When you reflect on the spaceflight achievement of the past fifty years which we mark at some length in this issue, can I ask to you consider this question “Am I impressed or disappointed with what has happened since October 1957 ?

You might well be terribly impressed on account of the number and variety of launches (around 6,000) since then with exploration of almost all the planets in our solar system, the manned Moon Landings, the Hubble Space Telescope and the growing international cooperation in space research being amongst the many highlights. The growing desire for space participation amongst wealthy people will also mean that the signs are propitious that space travel will indeed become much more commonplace in the coming decades.

But then again what might have been and has not happened ? Despite predictions following the euphoria of the first manned Moon landings we are nowhere near the realisation of a permanent base on the Moon and predictions of a date for manned visits to Mars seem to suggest that this will not happen for some 20 or 30 years yet. We also might have expected that a sophisticated and much larger permanent space station would have been in place long ago, given the starting progress made in the 1970’s but budgetary, political and philosophical considerations in the USA and in Europe have meant that what we have now in the shape of the ISS is a very modest achievement.

Sputnik 50

by Arie Olckers

Editor of Nieuwsbrief

Quarterly journal of Ruimtevaart Filatelie Club Nederland Specially translated for Orbit by Eleanor Coker On 4th October 1957, 50 years ago, the Soviet Union launched its first earth satellite - Sputnik. It was made up of an aluminium sphere with a diameter of 58 cm and a weight of 83.6 kg. This first satellite had four protruding antennae at the back. Inside this sphere was instrumentation for the measurement of air density and temperature that also collected data regarding the concentration of electrons in the atmosphere. The orbit of Sputnik lay between 227 and 941 km in height, the radio frequency was at 20.005 and 40.002 MHz and chemical batteries were used. A modified R-7 (SS-6 Sapwood) intercontinental rocket launched Sputnik.

With the knowledge we have now one might think that the first Sputnik was nothing special, namely a sphere with 4 transmitter antennae, that had nothing to do with the very advanced installations that are currently used in satellites and space laboratories.

The shock that the successful launch of the Sputnik caused in the United States was a heavy blow, in spite of the fact that on 06-01-1957 there had been a long article in Pravda about earth satellites and an announcement regarding launch possibilities. The result was that in America everything was concentrated on space travel research.

It can thus be said that space research got into its stride after the launch of the first Sputnik, that took place a mere 50 years ago.

The context of the launch M.K.Tichonravov, one of the leading people in the Russian rocket industry, had declared on 4th October 1951 that the USSR was as far ahead technologically as the United States and that it could launch an artificial earth satellite. On 27th November 1953 Alexander Nesmejanov from the Soviet Academy of Sciences announced that the creation of an artificial earth satellite was a real possibility.

In 1954 it appeared such a visionary outlook that Sergej P. Korolev had had when he wrote that now was the correct moment in time to form a research team for the pioneering work in the area of satellites and to make an in-depth study of the problems connected with them. In 1955 the Soviet Academy for Sciences sent 100 scholars a circular in which they were asked to comment on the use of artificial earth satellites and what these could do in space. The answers differed widely from no interest in fantasies to detailed plans.

On 30 August 1955 the Central Committee of the Academy for Sciences gave a special order to accelerate work on artificial earth satellites. Sergej P. Korolev said that within 1½ years there should be a launch rocket and that no time should be lost. A scientific programme had to be set up and there had to be factories to make the instruments and equipment for 5 to 6 satellites. One of Korolev’s co-workers said that it cost an insane effort before the first Sputnik went into space.

Russian 2007 Cosmonautics Day stamps here on cover provided by our Murmansk based member Andrei Aphonin also marks the coincident 100th birthdate of Korolev and 150th anniv of the birth year of Tsiokovsky.

“Top Secret” Project

50 Years of the Space Era

But it took nearly two years for this concept to receive powerful backing and begin realisation after passing the enactment of the Central Committee of CPSU (Communist Party of the Soviet Union) and Council of Ministers of the USSR № 149-88cc (cc – is Russian abbreviation of the “top secret”). This document provided for creation an undirected satellite for scientific purposes in 1957-1958. The mass of the satellite was stipulated to be in the range of 10001400 kg (including 200-300 kg of the scientific instruments) and the date of test launch was to be summer 1957.

In an article specially commissioned for Russian space expert Alexander Zheleznyakov, writes about the historical context in which Sputnik came to be launched.

This article was translated for us by his friend and colleague Boris Spassky.

Orbit

Mankind’s aspiration to overcome Earth's attraction and to set off for the stars appeared a long time ago.

Our ancestors must have dreamed about it when they lived in caves and later the best brains thought about it.

But it was only in the second half of the Twentieth Century that man could make his dreams a reality.

The draft of the apparatus appeared as early as July 1956. Despite the fact that it was intended exclusively for scientific tasks, all work on its creation was classified as secret and the satellite received the code name “Object D”. This was in fact the satellite, which was planned as the first space launch.

Officially the Space Era began on the 4th of October 1957 at 19:28:34 Greenwich, when the intercontinental ballistic rocket R-7 (now – famously called “The Seven”) launched from the missile test range at Tyura-Tam deep in the Kazakh steppes, which nowadays is better known as cosmodrome Baikonur. Within nine minutes it was orbiting as the world’s first artificial satellite.

From the very beginning difficulties appeared, which even Korolev with his energy and enthusiasm couldn’t overcome. He hoped that the scientists would see the possibilities which the satellites could grant them.

He anticipated that he would be swamped with proposals, among which it would be necessary to choose the best and interesting one.

The satellite project, which in the true sense of the word allowed a man to head for outer space, began in Soviet Union in 1954. The initiator of this project as well as a lot of other things in Soviet cosmonautics was Sergey Pavlovich Korolev and it was he who generated the idea of using military missiles which were being developed at that time for placing payloads, into near-earth orbit.

Instead of this he was faced with sluggishness and even laziness from the “academicians”. They proposed experiments and measurements, which could endow nothing new to Two of the three stamps science. The instruments, issued by Russia on which could be installed Cosmonautics Day this year onboard the satellite, were related to Sputnik and Korolev, shown here with the Sputnik massive and bulky. postmark. (The third was for

1998 and 2002 issues from Ukraine showing Korolev and his early Sputniks whilst below Soviet issues from 1977 and 1986 commemorate the “The Chief Designer”

Tsiolokovsky)

But this wasn’t the most crucial for Korolev. He would consent to everything if only to be the first in space. But the schedule of the instruments’ preparation was constantly frustrated. As early as the beginning of Autumn 1956 Korolev realised that if he trusted the Academy of Sciences, the Americans would put a satellite into orbit first.

So then Korolev made a difficult but necessary decision. When after a year of work the satellite mockups had still not been ready, he ordered his staff to prepare in parallel with the “Object D” something else, more simple. On the 25th of November 1956 young designer Nikolay Aleksandrovich Kutyrkin was given the task of the designing the simplest satellite, which was eventually to be launched as Sputnik.

Sputnik carried power-supply sources and two radio transmitters with the frequency 20.005 and 40.002 MHz. Satellite’s signals looked like telegraph transmission with the duration of 0.3 s. When one of the transmitters worked, the second had a pause.

Reception of their signals gave a possibility to investigate the conditions of the passage of radio waves from space to Earth and transmit information about pressure and temperature inside the satellite.

In the beginning of 1957 Korolev made a request to the Government to speed up preparation and realisation of the first launches of two rockets to put into orbit artificial satellites. He got permission but with the reservation: at first the intercontinental ballistic missile was to be perfected— and only then the satellite.

The satellite was undirected and the 4-antennae system provided nearly uniform beaming to all directions to exclude influence of its rotation on the intensity of the received radio signals. Electrochemical current source (silver-zinc batteries) with at least 2-3 weeks estimated period of work provided the power On the 15th of May 1957 the first R-7 rocket was supply for the onboard outfit. launched from Tyura-Tam, but to the dismay of its designers the launch was unsuccessful: the rocket The satellite was filled with nitrogen. The exploded within a minute of take-off because of a fire in temperature inside it was maintained at the level of 20 the tail section. to 30 oC by forced ventilation controlled with temperature gauges.

And the next launch was also abnormal. So it was only on the 21st of August that the rocket took off Officially the first Soviet satellite as well as the normally, passed all stages of flight without remarks and second one were launched in accordance with the the head section hit the mark. To strengthen the obligations undertaken at conferences during the success another “article” – this was the term used to International Geophysical Year. But it had a lot more, refer to samples of defence technology in the USSR – especially political significance. Its flight astonished the was launched on the 7th of September.

“Settled up” with the military, Korolev concentrated The New York Times newspaper wrote at that time his every efforts of his OKB-1 on the satellite.

“Energia”

The first Soviet satellite flew for 92 days till the 4 th of January 1958 and made 1440 rotations around the Earth. Then it entered the dense atmosphere layers and burnt. In physical sense the satellite died. But in a figurative sense it continues its flight in people’s mind even today.

People didn’t sleep at nights, strained themselves to breaking point doing their utmost, and on the 3 rd of October the rocket with the satellite was installed on the firing pad. And on the evening of the next day it headed for orbit.

No satellite before it could compare. Manufactured in the shape of a sphere, the satellite has four antennae which looked like spokes up to 2.9 meters in installed on its outer surface. Before launch they were folded up and “hidden” under the nose fairing and once in orbit hey were unfolded in operational position.

During the next 50 years a little fewer than 4900 space launches were realized in different countries.

4500 being successful. More than 6500 space vehicles have been put into near-Earth orbit and interplanetary routes. But all this happened later, after that simple but deeply significant “Bip! Bip! Bip!” sounded from the Earth orbit.

Un-manned Satellites on Postage Stamps : 23

By Guest Contributors Don Hillger and Garry Toth

Alouette and International Satellite for Ionospheric Studies (ISIS)

A checklist of postal items showing Alouette -series and ISIS-series satellites (http:// www.cira.colostate.edu/ramm/hillger/ Alouette.htm) is available on the Website developed by the authors for the unmanned satellites featured in this series of This is the twenty-third in a series of articles (http://www.cira.colostate.edu/ articles about un-manned satellites on ramm/hillger/satellites.htm).

Don Hillger Canadian satellite series: Alouette and can be reached at hillger@cira.colostate.edu International Satellite for Ionospheric Studies (ISIS). Two Alouettes were and Garry Toth at garry_toth@hotmail.com. launched, in 1962 and 1965.

Three ISIS were launched: ISIS-X, ISIS-1, and ISIS-2 in 1965, 1969, and 1971 respectively. A fourth in the ISIS series, ISIS-C, was canceled and never built.

Alouette-1 and 2 were small ionospheric observatories with various detectors and experiments, to study the effects of the ionosphere on communications. The bodies of these two spacecraft were similar, polyhedron in shape, about 1 m in diameter, but a bit flattened at the poles. The spacecraft were spin-stabilized at a slow rotation rate.

Among the several antennas were two dipole antennas, one pair up to 73 m long. The satellites had highly-inclined (80째) near-polar orbits: nearly circular at approximately 1000 km for Alouette-1, and elliptical (500 km perigee and 3000 km apogee) for Alouette-2.

ISIS-1 and 2 were also ionospheric observatories with numerous instruments, continuing the research successfully begun by the two Alouettes regarding the influence of solar activity on the ionosphere which directly affects communications.

The spacecraft bodies were all similar, polyhedron in shape, but a bit larger and less flattened than the Alouettes. Long dipole antennas like those on the Alouettes were used on ISIS as well. The satellites had highly-inclined (88째) near-polar orbits: elliptical (600 km perigee and 1500 km apogee) for ISIS-1, and nearly-circular at 1400 km for ISIS-2.

The earliest ISIS, ISIS-X, is better known as Explorer-31.

ISIS-X was launched in 1965 in conjunction with Alouette-2. Several instruments on board made direct measurements of selected ionospheric parameters.

The spacecraft was an octagonal prism about 0.7 m in diameter, launched into an elliptical orbit (500 km perigee and 3000 km apogee). The Explorer-series satellites were covered in the sixteenth article in this series.

Alouette has been featured on postal items from many countries besides Canada, but ISIS appears on only one stamp issued by Canada in 2000 (Scott 1831c).

Shuttle Story : 1994—STS-60, -62, -59, -65, -64, -68, & -66 The mission was launched on time at 7.10 a.m. EST on 3rd February and marked the first flight of a Russian cosmonaut on the Space Shuttle as part of an agreement between NASA and the Russian Space Agency on cooperation in human spaceflight.

The flight was the 60th shuttle mission and marked the return of the commercial Spacehab module to orbit. Spacehab carried twelve experiments, four involving materials science; seven involving life sciences and also a space dust collection experiment. Also on board was the Wake Shield Facility making the first of a series of flights.

The first attempt to deploy the Wake Shield Facility was made on flight day three. The free-flying experiment platform was designed to leave a vacuum wake in orbit in which high quality thin film layers of gallium arsenide and other semiconductor materials could be grown. However the first attempt was called off due to radio interference and difficulty in reading status signs on the platform. A second attempt was also called off due to problems with the platform’s attitude control system. The Wake Shield Facility remained suspended from the orbiter’s RMS where five out of a planned seven films were grown. The platform was scheduled to fly again in July 1995.

A number of NASA/RSA joint in-flight medical investigations were carried out and Russian cosmonaut Sergei Krikalev made use of the Shuttle Amateur Radio Experiment (SAREX) to talk to amateur radio operators in his native country. Conversations between the crew and the US President Clinton and Russian Prime Minister Chernomyrdin in Moscow also took place.

STS 60 carried the 100th Get Away Special canister to fly in space and the crew were involved in several deployments from GAS canisters. Six Orbital Debris Radar Calibration Spheres ranging in size from 5 to 15 cm were deployed to aid calibration of worldwide radar tracking systems. The German, University of Bremen’s BREMSAT was also deployed from a GAS canister to measure conditions such as acceleration forces affecting satellites.

Discovery's first attempt at a KSC landing on 11 February was called off due to unfavourable weather but a successful landing was achieved later in the day at 2:19 pm EST.

Unfavourable weather resulted in a one-day launch delay with lift-off taking place at 8.53am EST on March 4th.

Primary payloads located in Columbia’s payload bay were the US Microgravity Payload-2 (USMEL-2) which included five experiments investigating materials processing and crystal growth in microgravity and the Office of Areonautics and Space Technology-2 (OAST-2) which included six experiments focussing on space technology and spaceflight.

A variety of middeck experiments were also flown including Advanced Protein Crystal Growth, Commercial Protein Crystal Growth, Middeck Zero Gravity Dynamics Experiment and Bioreactor Demonstration Systems. The crew also conducted a number of biomedical activities aimed at better understanding and countering the effects of prolonged spaceflight.

The fourteen day mission came to an end on 18th March when Columbia glided down on to KSC runway 33 at 8.09 am EST to end a highly successful two weeks of microgravity research.

With a mission duration of over two weeks the flight of STS 65 became the longest shuttle flight to date.

Launch occurred on time on 8th July at 12.43 pm EDT following a smooth count-down. Aboard Columbia on its second flight was the International Microgravity Laboratory (IML) carrying more than twice the number of experiments and facilities flown on its first mission. The crew members, which included payload Specialist Chiaki Mukai, the first Japanese woman to fly in space, were divided into two teams to perform 24 hour research.

Over eighty experiments from six space agencies were located in the Spacelab module in the orbiter's payload bay. Fifty of these involved life science research including bioprocessing, space biology, human physiology and radiation biology. The Japanese Space agency provided the Aquatic Animal experiment unit which consisted of two independent systems that supported studies of live fish and small amphibians.

These contained Medaka fish goldfish and newts. Some of the equipment had flown on previous Spacelab flights such as ESA’s biorack which was making its third flight.

Nearly thirty experiments in materials processing were carried out using nine different types of facility. The solidification of materials from a liquid state in containerless environment was provided by the TEMPUS facility while crystals were grown in another facility called the Advanced Protein Crystallisation Facility.

The crew took time off during the mission to commemorate the 25th anniversary of the Apollo moon landing, noting it had also featured a spacecraft called Columbia. Aboard STS 65 was an Apollo 11 plaque

STS 68’s first launch attempt on 18th August was halted at T1.9 seconds when the orbiter computers shut down all three main engines after detecting an unacceptably high temperature in an engine turbopump turbine. As a result of this Endeavour was returned to the VAB to have all three engines replaced.

The launch was rescheduled for 30th September when lift-off occurred on time at 7.16 am EDT. STS 68 marked the second flight of the Space Radar Laboratory which had flown earlier in the year on STS 59.

Notably Mission Specialist Thomas Jones was making his second flight in the year. By flying the radar lab during different seasons it allowed scientists to compare changes between the two flights. Data were collected over the same locations as on the first flight but images were also obtained of an erupting volcano in Russia and several Japanese islands following an earthquake. The space radar on this flight also imaged a planned oil spill in the North Sea in order to test its ability to discern the difference between human induced and naturally occurring ocean film.

Other payload bad equipment included five Get Away Special canisters, two of which held 500,00 of the US Postal Service stamp commemorating the 25th Anniversary of Apollo 11 (as illustrated).

Middeck payloads included the Commercial Crystal Growth experiment to study the dynamics of protein crystallisation on CHROMEX-05, the fifth in a series designed to examine the effects of microgravity on plants.

Unacceptable weather in the KSC area resulted in Endeavour being diverted to Edwards Air Force Base in California where landing took place at 1.02 EDT on 11 October Above a launch and landing cover bearing the mission patch which depicts Exploration of Earth from space as the focus of the design of the insignia, the second flight of the Space Radar Laboratory (SRL-2).

Following a two year refurbishment, Atlantis lifted off on the final 1994 mission on 3rd November to carry out investigations of the Earth’s atmosphere and the effects of the Sun and human activities on its chemical composition.

Primary payloads aboard the orbiter were the ATLAS-3 instruments and the German built SPAS free-flying platform.

Flight

ATLAS-3 was a complement of six international experiments located on a pallet in the orbiter’s payload bay designed to study the Sun and map the Earth’s atmosphere. The ATLAS missions are planned to fly regularly over a 10 year period to analyse the chemical and physical components of the atmosphere.

MS MS MS MS

The free flying SPAS satellite was deployed from Atlantis on 4th November by French astronaut Jean-Francois Clervoy.

Carrying three infra-red telescopes and other instruments designed to create a three-dimensional map of the flow of gases in the Earth’s middle atmosphere the satellite spent eight days flying in formation with the Shuttle orbiter as it gathered data.

Tests were carried out with a middeck experiment called Heat Pipe Performance which involved applying specificallymeasured amounts of heat to various heat pipe designs flown, measuring the cooling capacity of the pipes and determining the limits of each design’s operation. The crew found time to perform additional tests beyond those originally planned.

These tests were aimed at providing data on cooling systems for the next generation of spacecraft and the space station.

Also onboard Atlantis were ten pregnant rats, the first pregnant mammals to fly aboard a US spacecraft and part of an experiment to examine how weightlessness affects foetal development.

The successful retrieval of the German SPAS satellite which had been trailing the orbit by upwards of 50 miles for most of the flight, rounded off the mission. The rendezvous with SPAS was attempted using a new method in anticipation of the 1995 Shuttle-Mir dockings. Normally an orbiter approaches its target from the front but on STS 66 Atlantis approached SPAS from below in order to avoid firing manoeuvring jets towards the satellite.

On a larger space structure as Mir on the international space station solar panels could easily be damaged by such firings.

FROM ATOM TO NUCLEAR POWERED SPACECRAFT PART 1: THE NUCLEAR THEORY by John Beenen

If we want to describe the history of the atom from the early beginning until the present generation of energy by nuclear reactors on Earth and in Space, we can divide our study into three phases. The first phase represents the discovery of the atom, the radio active radiation, the conversion of the elements and the chain fission, as a principle from earliest times but in effect from about 1895 until 1945. With a small overlap the development of the second phase, that from the atomic bomb, starts in 1939 and also lasts until 1945. After this year the emphasis is laid upon the peaceful application of nuclear energy first as a general source of energy, but also for the development of missiles with nuclear charge.

The Atom

(The first ideas about the structure of matter already date from the ancient Greeks. In the 5th century BC the atomic hypothesis was enunciated by Leucippos and Democritos.

According to them all matter is built from small units called ‘atoms’, which are the smallest particles from which a given substance can be divided.

That is contained in the word ‘atom’ which means ‘indivisible’.

At the same time a complete different hypothesis was formulated by Empedocles, and later on further developed by Aristotle. Both meant that matter originates from virgin dust called, ‘hyle’ or ‘ytem’, which is equal in all matter. The difference between substances is caused by the presence – in changing quantities – of certain properties imposed on the ‘first’ substance by the four basic elements: soil, water, air and fire.

(Aristotle, Cyprus 1978, M493) The great authority of Aristotle probably is responsible for this theory being held for over 2000 years. Even in the Middle Ages the Alchemists tried to obtain this ‘first’ substance from an other substance by eliminating the four basic elements. Doing so they thought that they should get other substances by adding the four elements again to the ‘first’ substance but now in different, the right, proportions.

Only in the 19th century via the work of John Dalton did the atomic theory appear again. By investigating how different elements were combining to form chemical substances Dalton concluded that every element

consists of atoms which form the indestructible and indivisible units of matter, but differ from atoms of other e l e m e n t s .

Today, knowing that more than a hundred elements exist this opinion should mean that the universe should contain the same amount of basic materials, for the time being a conclusion which is hard to believe.

In 1816 William Prout (1785-1850) came up with a kind of hybrid between both theories stating that all elements originate from one kind of atom, the hydrogen atom.

Modern atomic theory is considered to have started in 1789 when the German chemist Martin Heinrich Klaproth (1743-1817) in the mineral ‘pitchblend’ discovered the element uranium. Although he thought he had separated pure uranium later it appeared it was uranium oxide (see Canadian stamp Y744, 1980).

Finally the French chemist Eugène-Melchior Péligot (1811-1890) synthesized the first pure uranium.

Antoine Henri Bequerel (1852-1908)

(Becquerel, France 1946, M745) In 1896 French chemist Antoine Henri Bequerel discovered natural radio activity. And, somewhat before that time, Wilhelm Conrad Röntgen discovered a radiation causing fluorescence, which he called “X-rays” when he carried out electrical experiments in a high vacuum tube.

A year later, after a discussion with Henri Poincaré, Becquerel decided to compare these X-rays with his natural fluorescence. In his Paris laboratory he investigated the possibility that crystals of certain minerals after exposure to sunlight could emit roentgen radiation. Only one of these samples, a salt of uranium, appeared to have emitted a kind of radiation.

When these crystals, packed in black paper, were stored in a drawer for a couple of days lying on photographic paper they appeared to have caused a discolouration of the paper.

The radiation emitted from these crystals, however, differed from the X-rays and today such rays are called ‘gamma (γ)-rays’.

25

ORBIT

Becquerel very soon discovered that such radiation was harmful to men and badly affected human finger tips.

The Electron

(Thomson, Guinea 2001) The transport of electricity through gases at very low pressures was studied by a few scientists. As an electrical potential difference of several thousands of volts is applied between two poles melted in the ends of a glass tube, from which the air can be sucked away, at a certain low pressure one sees a greenish glow, a luminescence, in the tube.

The cause of this luminescence is some unknown radiation coming from the negative pole, the cathode, and this is why this kind of radiation is called ‘cathode rays’. The nature of this radiation was investigated by the Irishman Joseph John Thomson (1858-1940) who studied a series of electrical discharges in a high vacuum tube (discovered by the German Prof. Karl Braun in 1897). From the deviation of the rays by electrical plates he concluded that there were particles present much smaller than an atom. Such a particle received the name ‘electron’ and we now know it has a mass 1837 times smaller than the hydrogen atom. The electrical charge it carries is the smallest charge which can exist : every electrical charge is a whole multiple of the charge of an electron. This is an important realisation in understanding the essence of the quantum theory later on.

(Lorentz, The Netherlands 1928, Y217) The existence of the electron had already been predicted by others, including the Dutchman Hendrik Lorentz (1853-1928) (Y217,1928), but Thomson now showed it in practice.

In 1904 he suggested the atom as a small sphere with a positive charge around which electrons were orbiting influenced by electrostatic forces — the first representation of an atomic model.

Later it was discovered that there exist also other phenomena by which electrons were emitted such as the effect when substances, especially earth alkali metals (lithium, sodium, potassium, strontium) were irradiated by ultra violet radiation, producing the ‘photo electric effect’.

Also the former (and yet again present) radio tubes emit a flow of electrons, as some natural substances do such as Henry Becquerel discovered. This radiation was dubbed ‘beta (β)-radiation’.

Eventually (in 1903) Becquerel was awarded the

Nobel Prize for Physics for his discovery of natural radio activity.

Wilhelm Conrad Röntgen (1845-1923)

(Röntgen, Danzig 1939) But let us go back again to Wilhelm Conrad Röntgen. He received his basic education in The Netherlands, studied at the Utrecht University but passed his final exams in Zurich. Afterwards he worked at different Universities in Germany, but his most important work he carried out at Würzburg as a colleague from Helmholtz , Kohlrausch and Lorentz.

(X-rays, Germany 1995) In 1895 he studied the phenomena when he sent an electric current through a gas of extreme low pressure. On the evening of November 8th 1895 he found out, working in the dark, that when he wrapped the discharge tube in black cardboard, a piece of paper covered with a light sensitive material (barium platinum cyanide) started fluorescing even at a distance of two metres. Serial experiments showed that different objects placed within the source of radiation had a different effects on the photographic sheet. When he treated the hands of his wife the same way, he found at the development of the photographic sheet that the bone structure was clearly visible as well as her ring, but the flesh much less, so creating the first ‘roentgen picture’. (von Laue, Germany 1979, Y866) Because this kind of radiation was still unknown he called it ‘X-rays’. Later Max von Laue (1879-1960) showed that these were electromagnetic waves but with a much higher frequency than light. Finally they appeared to be identical to gamma rays.

In 1896 Pierre and Marie Curie called this kind of radiation ‘radio activity’ and synthesized the radio active elements polonium and radium form pitchblend.

The Curies

(Pierre and Marie Curie, France 1938, M433) After a scientific education at the Sorbonne in Paris Pierre Curie 1959-1906) finally ended as a professor at the Faculty for Science at the same University.

His primary work was crystallography, where together with his brother, Jacques, he discovered the piezoelectric effect.

Piezo-electricity is the property of some crystals to create a difference in voltage when a mechanical force is applied to the crystal.

The phenomenon is reversible which means that the crystal will change a little in shape when it is submitted to a difference in voltage. The change will be measured in nanometers (10-6 mm), but is large enough for a series of applications such as electrical lighters, gramophone elements, sonar, microphones, micro balances and ultra fine tuning of optical instruments.

The most well-known crystals for such applications are quartz and Rochelle salt.

her work on radium.

From both Curies there exist plenty of stamps. I myself have discovered at least 60 of them but undoubtedly there exist many more. Underneath are some: (Marie Curie, Poland 1982, M2810), (Marie Curie, radium, Poland 1992, M3375, (Pierre Curie, Cameroon 1986) (Joliot-Curie, France 1982, M2347)

Working in the field of magnetism he also found that magnetic effect changed influenced by certain temperatures. Above a certain temperature some magnetic materials lose their magnetism. The temperature by which such a phenomenon takes place still is called ‘Curie point’.

(Marie Curie, Poland 2004) In 1895 he married Marie Sklodowska (1867-1934) whose origins were Polish.

Together with his wife he worked under serious conditions on the properties of radium (element 88) from which they separated 0,1 gram starting from 2000 kg pitchblend. They also discovered the element polonium (element 84) named after Marie’s homeland.

They further found that the element thorium (nr.90) radiated the same type of radiation of uranium and concluded that this should have to do with the atomic nucleus of the element. For this type of element they introduced the name ‘radio activity’ of ‘radiation activity’. Soon their discovery led to the realisation of unlimited possibilities in energy such nuclei carried inside, but also their possibilities for warfare.

The Curies also suffered from damaged finger tips and other physical effects because of their work with radio active substances.

(Radium, France 1998) In 1903 together with Becquerel the Curies received the Nobel Price for Physics for their work on radio activity. After the death of Pierre Curie in 1906 because of a fatal accident Marie Curie once again received the Nobel Price in 1911 now for Chemistry for

Together with her husband Jean Frédéric Joliot (19001958) (M2347, 1982) their daughter Iréne Curie (18971956) was active in this field and both received their Nobel Price in 1935. They especially worked on the image of the nucleus of an atom, which in 1932 directly lead to the discovery of the ‘neutron’ by James Chadwick (1891-1974) and the ‘positron’ by Carl David Anderson (1905-1991).

(Chadwick, Gabon 2001), (Anderson, Guinea 2001) Their greatest discovery, however, was artificial radio activity. At the bombardment of boron (a base element with 5 electrons), aluminium (13) and Magnesium (12) with alpha-particles, they produced ‘isotopes’ from nitrogen (with 13 instead of its normal 7 electrons), phosphor (with 30 instead of 15), silica (with 27 instead of 14) and aluminium (with 28 instead of 13). These elements are not found in nature and decompose spontaneously under emission of positive and negative electrons.

Later on they worked together on the fission of the uranium nucleus and on the chain reaction and the conditions for an atomic reactor based upon uranium and heavy water.

With the approach of the Nazis in 1940 they succeed in transferring their documents and substances to England. Joliot was active in the French underground movement ‘Resistance’ and a founder of the French Communist Party. In 1946 he became the First High Commissioner for Atomic Energy and together with his wife he constructed the first French atomic reactor.

His spouse also was a Science Professor in Paris and member of the commission for atomic energy. She was active in the French women’s movement and together with her husband a member of the World Peace Council.

Sir Ernest Rutherford (1871-1937) (Rutherford, Romania 1971, M3004) Some of the most important contributions to the better understanding of the atom and radio activity came from a man originating from New-Zealand, Ernest Rutherford.

He was born as the fourth child and second son in a family of seven sons and five daughters and studied in New-Zealand and after a brilliant final exam from 1894 onwards in Cambridge, England under J.J.Thomson.

There he worked on the behaviour of gases treated with X-rays, the photo electrical effect and reported in 1898 the existence of α- and β-rays in uranium radiation. In the same year he accepted a job in Canada where he discovered a new gas, an isotope form radon.

(Soddy, Sweden 1981, M1177) Together with Frederick Soddy (1877-1956), who came from Oxford, he composed laws which r u l e d t he c o n v e r s i on o f radioactive elements and showed how they could be united into three families starting from uranium or thorium after a series of conversions all ending with lead. This appeared to be a spontaneous process which started with the creation of Earth.

The decay or disintegration of such a sequence of elements is called a radioactive sequence. Such disintegrations can follow quite slowly, but also can be very quick. The amount of radioactive atoms can decrease quickly but also at a slower rate. The way such radioactivity decreases is called ‘half-life’ time, the time by which the amount of active atoms is decreased to half. All radioactive elements possess their own specific half-life times.

Back in England in 1913 Soddy discovered the principle of ‘isotopes’ - elements of different atomic weight but still with the same properties. The word ‘isotope’

comes form the Greek words ‘iso = equal’ and ‘topos = place’, as isotopes are at the same place in the periodic system of elements (see later).

By the way, it also was Soddy who even before the publication of Einstein’s famous formula predicted that an atom contains an enormous amount of energy and he stated that if this could be liberated it would change the world.

Periodic System of Elements

(Berzelius, Sweden 1979, M1073) Having arrived at this point. for a good understanding it is good to take a trip into chemistry and the Periodic System of the Elements. By the beginning of the 19th century the Swedish chemist Jöns Berzelius (1779-1848) had identified 34 elements, of which at that time carbon, oxygen, hydrogen and sulphur were the most important. Compared to the ancient alchemy the instruments were largely improved and application of ‘Volta’s pile’ lead to numerous electrical methods for investigation of the composition of substances.

A very fruitful method of analysis was founded on the fact that certain elements give a certain colour to a flame. From our fireworks we all know the red colour of the element strontium and the green of barium. Many chemists tried to create order in the newly discovered elements. It was already clear that there existed certain families with more or less equal properties, such as the halogens: chlorine, iodine, and bromine. In 1869 Lothar Meyer set out the atomic volume against the atomic weight thus showing that a periodic function in properties existed depending on atomic weight.

(Mendelejeff, Poland 1959, M1133) In 1872 the Russian chemist Dimitri Mendelejeff (1834-1907) constructed a table, in which he not only could divide the present 60 elements into eight classes but also could predict the existence of 26 by that time unknown elements.

The present table still contains 87 natural elements with a stable isotope.

From the atomic number 88 (radium) onwards the elements become radioactive, and from the element 93 (neptunium) on they do not exist anymore in common nature, but are man made. In the meantime there exist one or more radioactive isotopes of every element . The most stable isotope of the most well-known artificial element plutonium (nr.94) has a half-life time of 82 million years.

28

ORBIT

By radioactive elements, which change slowly (and sometimes very quickly) under emission of a certain radiation, their half-life-time can be predicted, the time by which half of the initially present atoms will have disappeared, or ‘decayed’ in technical language.

Another term important for the understanding of radioactivity is the word ‘electron volt’. In nuclear physics this word is used in stead of ‘ erg’ or ‘joule’.

When a proton or an electron is accelerated in an electrical field it gets an energy proportional to the potential of the field passed. Thus, an electron volt is just that amount of energy which a proton or electron gets when he passes a potential difference of one volt.

The Proton

(Rutherford, New Zealand 1971) Together with Henry Gwyn Moseley (1887-1915) in 1913 Ernest Rutherford proved that every element had its own specific atom number, connected with its properties. It has been shown that the number of electrons orbiting around a nucleus forms the most important properties of the atom.

It determines its place in the Periodic System of Elements. Hydrogen which only has one electron takes the first position, helium with two electrons the second, oxygen the eighth and uranium is number 92. Atom models sometimes are subjects on stamps such as: (Japan, Germany 1955 Y86, Belgium/United Nations 1958 Airmail Y35, M1115)

The atomic number also determines also the chemical properties of an element as all chemical processes are caused by a change of the configuration of the electrons. The nucleus does not take part of these processes. The nucleus is only very small, about 10,000 times smaller than the atom as a whole. On the other hand the nucleus contains nearly all the mass. Hence, the nucleus is the siege of matter and if we want to know something about the structure of a substance we have to know the structure of the nucleus.

About 1919, mainly via the work of Francis William Aston (1877-1945), it was clear that most elements were not singular but a mix of different types of atoms differing in weight, isotopes. When the atomic weights of the separate isotopes were determined the astounding effect appeared that they were

nearly whole numbers, which could be expressed as a function of the atomic weight of the most simple substance, hydrogen. This led to the supposition that the nuclei of all elements were build out of hydrogen.

This hydrogen nucleus, containing one elementary positive charge, got the name ‘proton’ a Greek word literally meaning ‘the first’.

In 1919 this supposition made by Rutherford finally was proved experimentally. When together with Moseley using high-energetic alpha-particles he succeeded in disintegrating the nuclei of certain light elements such as nitrogen. By doing so he released hydrogen nuclei.

Rutherford concluded that the sole source of these nuclei was the nitrogen and therefore nitrogen should contain hydrogen nuclei. He suggested that the hydrogen nucleus, now known as element number one, is an elementary particle. This discovery is considered as the discovery of the proton, one of the building stones of the nucleus of an atom. Later it was proved that within this process also oxygen was released. So Rutherford actually was the first who converted one element into an other.

But now back to Rutherford and his co-operators such as Otto Hahn, who, in 1905-06, was to discover the fission of the nucleus.

(Bohr, Denmark 1963, M417) In Manchester Rutherford continued his investigations which led to his greatest discovery in 1910, the principal structure of the atom. In 1912 he received support from the Dane Niels Bohr (1885-1962) (Y427, 1963), who rearranged Rutherford’s theory to the— in the meantime by Max Planck postulated - Quantum theory, which will be discussed later.

(Atomic model, Turkey 1963, M1864) According this model an atom looks like a solar system built from a central nucleus and one or more electrons orbiting around it at different distances. The nucleus is positively charged and in its final structure the amount of electrons is such that their charge is just in equilibrium with that of the nucleus, the whole being electrically neutral. However, this only counts for neutral basic elements, not for magnetic. In such elements a surplus of electrons exists.

29

ORBIT

The Neutron and other -Ons (Chadwick, Maldives, 1995) It was only a few years before Sir James Chadwick (1891-1974) in 1932 discovered the ‘neutron’, thus, entering a little deeper into the composition of the atom.

He proved that the nucleus consists from positively charged protons and neutrons. Neutrons do not have a charge and have a mass about equal to protons. By light elements the amount of protons and neutrons is equal but as the element is heavier, the amount of neutron increases more rapidly until the level where the nucleus is becoming unstable and is emitting radiation.

This radiation can be alpha(α)-particles, helium nuclei consisting from two protons and two neutrons, beta(β)particles, electrons, or gamma(γ)-rays, electromagnetic waves of an extremely high frequency. (In reality it is much more complicated but that falls outside the scope of this article).

For a further knowledge of nuclear forces it is worthwhile to know that in general α- and β-particles only possess a minor penetrating effect, but that neutrons by their lack of charge are much more dangerous as well as γ-rays or, as formerly termed, Xrays. (de Hevesy, Hungary 1988, M3997, Use of radiation at oncology, I r a n ) The Hungarian Professor George de Hevesy (1885-1966), later especially known as the forerunner for the use of radioactive radiation in medicine, was one of Rutherford’s pupils. Together with the Dutchman Dirk Coster (1889-1950) in 1923 in Kopenhagen de Hevesy discovered also the element Hafnium (nr.72).

De Hevesy was a pioneer for the use of radioactive isotopes as tracers in medicine, the effect of X-rays on tumours and other investigations in the field of cancer, a specialist area nowadays known as radio chemistry.

Rutherford’s work created many more winners of the Nobel Prize such as: Aston (1921); Chadwick (1935), G.P.Thomson (1937), Appleton (1947), Blackett (1948), Powell (1950), and Cockroft and Walton (1951); with exception of Aston, who received the prize for chemistry, all for physics. He himself received the Nobel Prize for Chemistry in 1908.

Rutherford was married and had one daughter. He passed away on October 9th 1937 in Cambridge and is buried in Westminster Abbey besides Sir Isaac Newton and Lord Kelvin.

Units and Dose

To distinguish the activity of radioactive substances from each other some units were introduced. The unit of radioactivity is called after the discoverer, Becquerel.

One ‘Becquerel’ correspond with one disintegration per second. Formerly the far greater but very awkward unit the ‘Curie’ was used, corresponding with the radioactivity of 1 gram of radium i.e. 37 milliard (3,7*1010) disintegrations per second of emitted radiation.

But a unit exists also for absorbed radiation, the ‘Rad’ (Radiation Absorbed Dose) nowadays mostly the ‘Gray’ (symbol Gy) (1 Gray = 1 J/kg = 100 Rad), called after Louis Harold Gray (1905-1965), a British physicist working on radiation biology.

As the biological effect is not alike for every kind of radiation sometimes this is also considered. Fomerly (and still now and then) this was expressed in ‘Rem’(Roentgen Equivalent Man). For roentgen and gamma radiation the Rad is equal to Rem. Today, for the equivalent dose ionising radiation, by which man is exposed over a certain period, the ‘ sievert ’ (symbol Sv), has been introduced, called after the Swedish medical physicist Rolf Sievert (18961966). One Sievert is equal to a received dose of 1 J/kg and equal to100 Rem. As we should like to know which are the effects of radiation to man here are examples: A massive dose at one time over the whole body of 1000 Rad or 10-20 Gray is lethal. This corresponds with a quantity of about 1000 Joule for an adult. Actually this is only very little energy corresponding with the energy in 60 mg of sugar.

At 300 Rad one has a 50% chance of survival. During X -ray, you get a dose of about 50 millirad or 0,05 Rad, but at the radiation of cancer tumours locally a dose rate of even some thousands of Rads is imposed.

But even without these extreme exposures we get our daily dose of radiation. In fact the natural radiation is still the most important source of radiation to man.

The yearly amount of radiation which we receive from the cosmos is about 28 millirad, but at some places on earth more radiation can be found outside and the 30

ORBIT

imposed dose can increase with a factor of ten. Such areas have been found at Italy (Lazio, Campania) and France, but especially in India (Kerala, Tamil Nadu) and Brazil (Espirito Santo, Minas Gerais).

The radiation we receive from radioactive sources from our appliances mostly is alpha radiation, from which penetration is very limited. Most radiation will be kept out by walls or glass in our houses and buildings.

(Cosmic Radiation, Macao 2004) Cosmic radiation is responsible for about 7% of the daily dose we receive.

When we are flying by airplane we receive some additional amount of radiation from about 0,5 millirad per hour. Astronauts take more risks passing the van Allen radiation belt in which a larger amount of high-energy particles are present. They receive an extra dose of between 150-500 millirad.

Natural background radiation varies strongly with location, but as a mean the effective dose for a member of the population is about 1m5 mSv per year. Certainly in the meantime norms have been set to which radiation sources have to comply. For our population a yearly burdening of maximum 170 millirad or millirem is set as a target. But of course for people handling radiological apparatus other limits are in force.

Further radiation is introduced in our bodies by food especially over an isotope of carbon, carbon-14 (C14).

By the way, for the whole body this is not more than 1,3 millirad per year, but from other isotopes we receive much more. An isotope of potassium ( 40K) gives 17 millirad over the whole body and 27 millirad in the red bone marrow.

Also water introduces some radiation. In normal areas this is less than 0,001 Becquerel Uranium-238 (238U) per litre, but also here there exist areas where this can increase to as much as 30 Becquerel.

Almost finally, every day we receive a small amount of uranium, thorium and radium responsible for 0,1 millirad per year in the soft tissue and 2 millirad in the periosteum (bone membrane).

But still this is not all. There exists a radioactive gas ‘radon’ which enters our homes through the creeping spaces under our floors. As a matter of fact, this is the most important source of radiation we receive, about 55%.

Quantum theory

Quantum theory (quantum = quantity) is especially important in the understanding of the composition of the atom. It describes the behaviour of energy and matter at the level of the atom. From the time of the drafting of quantum theory it was already known that an atom is constructed from a nucleus with orbiting electrons. With the theory present at that time, however, it was not understood why these electrons did not circle slowly around the heavy nucleus as satellites do to earth. That does not happen otherwise we would not exist.

In 1690 the Dutchman Christiaan Huygens supposed that light was made up of waves. Isaac Newton explained in 1764 that light comprises particles. Since then it became known that light has wavelike but also particle like characteristics.

The mean received dose by breathing outdoor air is about 1 millirad in our lungs, but in our houses this may raise with a hundred times more especially when we ventilate too little.

(de Broglie, France 1994, M3022) In 1923 Louis deBroglie (1892-1987) supposed that matter particles showed wavelike properties which in 1927 was also shown to be the case for electrons by Clinton Davisson (1881-1958) and Leslie Germer (1896-1971).

Also some building products contain radon gas, such as granite, brick and concrete. Synthetically produced gypsum as a side-product of the fertilizer production is notorious by its radioactive radium-226 (226Ra) content. Radium 226 is about one million times more radioactive than uranium and has a half-life time of 1602 year and slowly decays into radon gas. The gas formerly therefore was also called (radium) ‘emanation’.

I will not go too deeply into the theory therefore I will leave it that slowly it became clear that the wavelike aspect of such particles referred to the probability of the condition and the position of the particle. Finally this led to the ‘Uncertainty Principle’ developed by Werner Heisenberg (1901-1976), which explains that the place in space or its speed can be detected precisely from a particle but never the two together.

Via all of these burdens we get finally yearly something in the region of 100 millirad of radiation.

(Planck’s Constant DDR 1958, Y344) The basis for quantum theory was led at the beginning of the 20th century by scientists such as: Albert Einstein, Max 31

Planck, Niels Bohr, Erwin Schrödinger, Werner Cambridge and in 1931 started a group at Kharkov. In Heisenberg, Max Born, John von Neumann, Paul Dirac, 1921 Pyotr Kapitsa (КАПИЦА,1894-1984) came to and Wolfgang Pauli.

Especially because of the work of Max Planck (1858-1947) Among other work he carried out the first experiment (Sweden, Y1034, 1978; DDR with a cloud-chamber and studied the deviation of alpha Y344, 1958) around 1900 it particles in a strong elector magnetic field. Back in became clear that wave energy Moscow he not only worked at this subject but also did could be described as consisting low-temperature research and in 1937 discovered the from small packages (quanta) of super fluidity of helium. In WW II he produced oxygen energy showing particle like for low-pressure expansion tubes. After the war he properties. The energy is so-to-say divided in packages developed heavy microwave generators and discovered and is not a continuous flow. a new kind of high pressure plasma discharge with a temperature over one million degrees.

He studied how radiation emitted by a black body depended on the body’s temperature. He detected that Vladimir Vernadsky (ВЕРНАДСКИЙ, 1863-1945) was a if he multiplied the frequency of the wave with a scientist with very broad interests working on subjects constant he got the energy of the wave. This constant such as geochemistry, mineralogy, bio-geometry and today is called the: ‘Planck’s Constant’ and is expressed crystallography. As a biochemist he created of the term by the character ‘h’ in the formula: E = h . v, in which ‘biosphere’.

‘E’ represents the energy and ‘v’ the frequency. The value for Planck’s Constant is: 6,626068x10-34 m2 kg/s.

(Ioffe, CCCP 1980, M5007) Abram Ioffe (ИОФФЕ,1880-1960) (USSR, M5007, By the way, it is interesting to note that Planck did 1980) led a group in Leningrad, which originate this theory, but he did not completely believe included Igor Kurchatov (КУРЧАТОВ, in it. Einstein was a opponent of quantum theory 1903-1960, Rossya 2003) later to be because it did not fit in his beliefs about the Universe director of the Soviet a tomic and also because the uncertainty principle put an end programme. They studied all aspects of to the fact that in science everything is measurable. the physics of the atom. In 1932 they built together the first Russian cyclotron. In later years Quantum theory had an enormous impact on our Ioffe refused the position of the director of the Soviet insight in elementary processes and therefore our atomic bomb and accordingly was relieved from his technical skills. A direct result from quantum theory is post in 1950. the transistor, the laser and the electron microscope.

But quantum theory is so complicated for a layman, At the end of the thirties different cyclotrons were such as your writer, that for the rest I will keep silent. erected in Russia.

“A Life in Space” by Tim Furniss, featuring the Challenger cover-up SPACEPORT PUBLISHING…….PRESENTS: Buy the e-book at www.spaceport.co.uk!

Available now! Easy purchasing via PayPal for download!

The Challenger Cover Up The Space Shuttle Challenger accident on 28 January 1986 was not caused by an O- ring failure on one of the solid rocket boosters but by a structural failure of the booster in the region of the semicircular attach ring, which attached it to the external tank.

As Challenger rose into the skies, the right hand booster was shedding pieces from the damaged booster and was fishtailing slightly through the sky - a fact that was clearly recognised by the crew, who had worked out was wrong, were on the point of saving the orbiter and crew but ran out of time. They were within 1 sec of saving the mission with a contingency abort!

This is revealed in a book published by British spaceflight journalist Tim Furniss, who was the spaceflight correspondent of Flight International magazine from 19842006.

“A Life in Space”, an ebook, tells the story of a 12 year-old boy whose enthusiasm for space was fired by Yuri Gagarin’s flight on 12 April 1961. Tim purchased his first copy Flight International in 1962, when the magazine featured a Space Special issue and continued to read it every week.

Tim’s ambition was to become a spaceflight journalist and to meet astronauts, visit spaceports and to see launches. He witnessed Apollo, Shuttle and other launches from Cape Canaveral, Kennedy Space Centre and Baikonur.

In 1984 he became Flight International’s space correspondent. His ambition reached its peak, when he was the first British journalist to watch a manned launched from the Baikonur Cosmodrome, in 1988. As he stood on Gagarin’s launch pad 1, Tim remembered with thanks to God for that day in 1961.

His inspirational story - like “The Rocket Boys” (October Sky) and “Billy Elliot” – screenplay in progress - is linked with a first hand history of the space age, which began on 4 October 1957, with the launch of Sputnik 1 - from the same launch pad that launched Gagarin - to the present day, including all the main events, including Gagarin, Apollo 11 and the Challenger accident.

The official cause of this accident was an O-ring failure, a conclusion made in great haste by the Rogers Commission, which overlooked or disregarded vital evidence but was also not provided with the full information from NASA. Like a good detective story, concerns about the O rings in cold weather were raised by engineers at Morton Thiokol but these were actually a red herring.

were on the point of saving the orbiter but ran out of time.

Dick Scobee and Mike Smith were within 1 sec of saving the mission with a contingency abort!

NASA very carefully censored any images that showed what was really happening - unlike the hundreds of views from several angles that were usually published after a launch. The space agency also misidentified the crew cabin falling into the sea, which explained why it took so long to find the fallen seven-person crew, which included the schoolteacher, Christa McAuliffe.

Amateur video coverage seen from the north of the Kennedy Space Centre, clearly shows the right hand booster shedding debris and trailing a third “spluttering” contrail.

American aereospace engineer, Ali Abutaha dedicated years investigating the accident but was persecuted and rubbished

by NASA, which took all his findings aboard and redesigned the Shuttle - including a fully-circumferential attach ring which was clear to see on the Shuttle’s Return to Flight in 1989. “No reader could find what you're writing about anywhere else!”, says Ali. “A Life in Space”, the inspiring, amusing, moving, frank, intimate, surprising and feel-good read, can be purchased from Spaceport Publishing as a download on Tim’s website, www.spaceport.co.uk. An outline synopsis is also available on the website. A short biography is also available.

Challenger snippets ….. “messy” contrail coming from one of the SRBs …TV image going in and out of focus …the SSMEs gimblal in an unusual fashion…it has been reported that Challenger hit a “54kt wind shear at T+50s” in the flight... NASA did not launch Space Shuttles into wind shear!…The “wind shear” was the Challenger “zigzagging” due to a breached booster… NASA photo team noticed the third plume seen from New Smyrna Beach north of the KSC and even told the Commission but this was not taken up!.…a private video taken from the north shows an extra trail… the Rogers Commission showed only the final two seconds!...Five key pieces of the SRB fell off during the launch …an airline pilot flying SE said smoke was seen streaming “out of the wall” of the right hand booster… he saw the SRB separation motors fire...who fired them? … the crew knew the SRB was in trouble!!…Ali Abutaha, a dynamics engineer examined hundreds of Time magazine images … some show that the fire started at lift-off and continued through the ascent! …Time never published them!…the crew was obviously aware, used the readouts from the upper cable tray (giving the pressure in the upper segments) and punched the SRBs away - but it was just too late…NASA took six weeks to the find the crew compartment because it identified the wrong object!….Abutaha’s findings were rejected by NASA but the agency used his analysis to change the Shuttle ……. MUCH MORE!!!!.

Dear Jeff, Browsing through my collection for another Orbit story I found a postal cancel from the Belgian Post for astronaut Dirk Frimout, who was the leading player in the piece “Apollo 3000—A Rollercoaster in Space,” published in Orbit no 74 for June 2007. The cancel illustration below shows the shuttle Atlantis in which Frimout flew in March 1992 orbiting around Earth.

“Viering Dirk Frimout (Celebrating D.F.)” says the text of the cancel from Poperinge, the Flemish birthplace of the astronaut. The date is May 23, 1992. The Europe 14F stamp used depicts the satellite Olympus.

Editor’s note—an example from Ian’s web pages….. the exploration of space. The abstract nature of these stamps 1991 Europe in Space (GB) will have intrigued and baffled in equal measure.

These four stamps, joined in two pairs, honour the work of Stanley Gibbons nos. 1560–1563 European astronomers at the Roque de los Muchachos Observatory on La Palma in the Canary Islands, where the UK plays a major role. Contributing to the pan-European spirit behind the issue, the stamps were designed by a Belgian artist, Jean-Michel Folon. According to the Royal Mail, they were meant “to set minds wondering about the mysteries of space”. The 22p pair is intended to convey the idea of looking out into space while the 37p pair supposedly suggests someone looking back at us. An eye on each stamp symbolizes
