Rocket

The first rockets blasted Chinese fireworks into the sky a thousand years ago. Now they send people into space.

It is ROCKET SCIENCE, actually !

Wernher von Braun led the team behind the first US satellite and the Moon landings. By the way... My V-2 rocket flew at more than 3,420 mph (5,500 km/h), and delivered a ton of explosives.

We have liftoff!

To soar into the sky, a rocket needs enough fuel to lift its weight, have a safe way of burning that fuel very quickly, and be able to work in an airless environment if it gets to space. American scientist Robert Goddard was the first to solve these problems: He launched the world’s first liquid-fueled rocket in 1926. It was light, but packed enough punch to just about get it off the ground, though it didn’t reach space.

Wernher’s V-2

People realized that rockets could be used both to send humans into space and to fire weapons. German Wernher von Braun’s V-2 rocket was first used in 1944 during World War II. After Germany was defeated in the war, von Braun moved to the United States and pursued his dream of developing rockets for spaCe TRaVel.

It paved the way for…

The V-2 was the first ballistic missile. The first intercontinental ballistic missile, the soViet R-7, was launched in 1957.

The Mariner 2, launched by a rocket, became the first space probe to visit another planet when it reached Venus in 1962.

The Soviet Union (modern-day Russia and other Eastern European countries) blasted the first satellite into space in 1957 using the Sputnik rocket, designed by Sergey Korolev. Korolev also developed the Vostok rocket, which shot the first human being, Yuri Gagarin (left), into orbit in 1961.

Man on the Moon

Soon after, in the United States, von Braun designed the Saturn v rocket (right) that took the first people to the Moon during the Apollo 11 mission. The rocket was 363 ft (111 m) tall, but only the command module (the cabin for the astronauts) was designed to return to Earth. Most of the rocket consisted of tanks that housed the fuel needed to escape earth’s gravity.

Payload

HOW All rockets burn fuel, either solid or liquid, to provide thrust. IT WO R KS V-2 rockets used liquid fuel and liquid oxygen. These are stored in big fuel tanks. They are mixed together in the combustion chamber and burned to become hot gas. The gas is then pushed out the back of the engine to drive the rocket forward. Guidance system

Russia’s Mir space station was assembled in stages in space. It was manned for most of its 15-year life. america’s reusable space shuttle was launched exactly 20 years after yuri

GaGarin became the first person in space.
