One of the major threats to intelligent life in our universe is a high probability of an asteroid colliding with inhabitable planets. STEPHEN HAWKING
LETTER FROM THE CEO This year has been a year of change, new discoveries, and growth. The support of our donors and the planetary defense community has allowed B612 to be at the forefront of efforts to prevent major asteroid impacts. Something that our B612 supporters can be justifiably proud of is that the 2008 Congressionally mandated goal of finding 90% of NEOs larger than 140 meters is within reach. We believe this goal can be reached because of full federal funding for the Large Synoptic Survey Telescope (LSST) in addition to potential NASA funding for the NEOCam infrared space telescope, which B612 advocates. Because of this progress, it is our intention to package our research on Sentinel as a design reference mission for solar orbiting infrared asteroid space telescopes so that other scientists can benefit from our findings. The 140 meter asteroid detection goal was established by what was thought technically possible in 2008. But 99% of asteroids capable of causing great damage are smaller than 140 meters. These asteroids will go largely undiscovered by LSST or NEOCam, but could still pack the explosive energy of a large nuclear bomb, such as the Tunguska asteroid in 1908 which was equivalent to over 5 Megatons of TNT impact energy. We have therefore been investigating a promising new technology called synthetic tracking. This technology could allow us to address this size range below 140 meters. Synthetic tracking uses extremely fast data processing to compensate for the rapid motion of small asteroids (which are necessarily closer to the telescope than larger asteroids). We have been working jointly with a group of scientists at CalTech and the Jet Propulsion Laboratory (JPL) and have already successfully demonstrated the technique on a ground based telescope. We are studying the possibility of testing a synthetic tracking telescope in Earth orbit.

LETTER FROM THE CEO
A consequence of the impending huge improvement in observing capabilities is that we face a deluge of new asteroid discoveries, and we will be forced to make asteroid deflection decisions in the coming years. In response, we are moving forward on the important job of creating a more capable and open system for understanding, analyzing, and assessing impact and deflection scenarios. This work, called the Asteroid Decision Analysis Machine or ADAM, continues to gain traction both within our donor community and with scientific and technology partners. Our public education activities included the second annual Asteroid Day on June 30th which was an international success. Through this effort, the scientific community comes together to share research and educate the public. After first announcing Asteroid Day in December 2014, we are pleased to see depth of interest in asteroid awareness and planetary defense. The UN will consider designating Asteroid Day as an officially recognized day by the end of this year. B612 has transitioned from a small group of committed people with visionary goals into a steady organization with a clear place in an important and emerging field. We have leveraged the donations from our supporters to help change the world. In the coming year we will continue this strategy of leveraging our supporters’ investments in the best possible way — for the maximum benefit to the field.
To our future,
Ed Lu Chief Executive Officer and Co-founder B612 Foundation

ABOUT US
Navigating a Dynamic and Emerging Field What started as a visionary idea to develop the technology to deflect an asteroid in 2002 between Ed Lu, Rusty Schweickart, Clark Chapman, Piet Hut, and 20 of the world’s top scientists, has grown into a world-renowned organization with an important role in the emerging field of planetary defense. For years, Ed and Rusty advocated for increased asteroid detection and many victories resulted from their efforts. Asteroid detection is now debated seriously in scientific, governmental, and public conversations. The landscape has shifted. Advancements in Asteroid Detection Since the announcement of the Sentinel Mission in 2012, a time when major efforts in asteroid detection were not being funded adequately, new telescopes, including the Large Synoptic

Survey Telescope (LSST), have been funded, and others are being considered. Given our technical expertise, B612 has an important role arguing for the best detection projects to be carried out and furthermore that the resulting asteroid deflection decisions are made in a systematic and open way. In the Coming Year B612 will build upon its work to advance the field of planetary defense, continuing with programs in science & technology and advocacy & public education. We have five primary objectives driving our work in the coming year. They are to: 1. Ensure the most effective technologies for detecting near-Earth asteroids are advanced. 2. Advance the research and tools needed to create a more efficient and open system for evaluating, analyzing, and assessing asteroid deflection scenarios through the Asteroid Decision Analysis Machine or Project ADAM. 3. Demonstrate synthetic tracking for space based asteroid observations using data from an existing Low Earth Orbiting satellite. 4. Package our research and work on Sentinel as a design reference mission, analyzing the performance of a solar orbiting infrared space telescope for detecting near-Earth asteroids. 5. Drive the global conversation around the need for increased asteroid awareness through activities such as Asteroid Day.

In June 2012, B612 announced the Sentinel Space Telescope project because at the time there were no funded prospects for large telescopes that could fully address the problem of finding asteroids larger than 140 meters. Since then, private donors have enabled B612 and Ball Aerospace to model and verify the Sentinel Mission performance and advance our scientific understanding of how telescopes like Sentinel would perform under realistic circumstances. Efforts with Sentinel also helped catalyze progress in the field by increasing the pressure for federal support. Since 2015, there have been two major developments. First, LSST received full federal government funding and is slated to begin operations in 2022. Second, the NASA’s proposed NEOCam infrared space telescope mission has been selected as a finalist by the NASA Discovery Program, competing to win selection for flight, with a final decision to be made at the end of 2016 or early 2017. B612 has publicly stated its support for NASA to select NEOCam for funding. With regards to Sentinel, B612 plans to publish our findings so our work can serve as a design reference mission for others interested in advancing infrared space telescopes. B612 is now investigating new and potentially much less expensive technologies to help solve the still unresolved issue of detecting asteroids <140 meters which are vastly more numerous than asteroids larger than 140 meters yet still capable of great destruction. This technology, called synthetic tracking, is described later in this report.

HOW WILL WE KNOW WHICH ASTEROIDS ARE REAL THREATS THAT REQUIRE ACTION? AND, HOW WILL WE MAKE INFORMED DECISIONS ABOUT THOSE THREATS?
INTRODUCING ADAM The Asteroid Decision Analysis Machine or ADAM is a new B612 project that will provide analytical tools needed to help world leaders, scientists and citizens interpret, understand, and manage the unprecedented flood of asteroid discoveries expected within the coming decade. ADAM will provide theoretical analysis to understand asteroid deflection scenarios, as well as tools to analyze specific asteroid threat cases. Advancements and New Challenges Since the the founding of B612 in 2002, the planetary defense community has grown substantially and the number of telescopes capable of mapping Near Earth Objects (NEOs) has increased. Today there are hundreds of scientists around the world working to protect the Earth from asteroid impacts. Paradoxically, these advances have lead to a new set of challenges. The new and vastly improved capability to track asteroids and to know in advance of potentially threatening NEOs means that we will increasingly be faced with decisions of whether or not to mount an actual asteroid

deflection campaign. The current discovery rate of asteroids is about 30 per week. In a few years, when the discovery rate of asteroids is thousands of asteroids per week, we must ask ourselves, how will we know which asteroids are real threats that require action? How will we make informed decisions about those threats?
INTRODUCING ADAM
11
Risk Assessment, Deflection and Geopolitical Concerns Once an asteroid is discovered, an initial best fit orbit is calculated. Asteroids whose orbital tracks intersect the Earthâ&#x20AC;&#x2122;s orbital track have a possibility of eventually impacting Earth. The planetary defense community must ask whether or not action needs to be taken to mount an asteroid deflection campaign. Through ADAM, B612 will investigate the variety and number of asteroid decision cases

then ensure that the international community is informed and empowered to take part in the inevitable decision-making process of protecting against asteroid impacts. After the analysis of an individual asteroid is completed, the decision on whether or not to launch an asteroid deflection campaign remains complex because such a decision involves political as well as technical factors. Different countries will have unique political, social, and economic motivations and constraints, and will weigh these factors differently. The International Asteroid Warning Network (IAWN) at the United Nations is being set up to address these issues, although their work is still in its infancy.

INTRODUCING ADAM
The canyons of Arizona from the International Space Station, by Ed Lu
A goal of ADAM is to develop a long term robust solution to the challenge of asteroid threat analysis by making our analysis tools open to the planetary defense community. In this way, the community will be able to analyze and understand asteroid threats in a way that they currently cannot independently do. Ultimately, this will lead to better decision making because the various members of the community will be better informed. Long term, because the capability to understand asteroid impact threats will be distributed, we will be more effective at determining deflection scenarios. We will work with the planetary defense community to define and build useful analysis tools and will ensure there is open access to the raw observational data upon which these analyses will be built. ADAM will be carried out in three phases over the next several years:
PHASE 1
PHASE 2
PHASE 3
Build and test basic asteroid threat analysis tools
Use software tools and build theoretical models to better understand impact uncertainty and deflection options and implications
Make the software tools widely accessible to the planetary defense community
User Community and Public Education A critical part of this work will be to inform and educate policy makers and the public on the meaning of asteroid threats. A whole new vocabulary surrounding asteroid threats will need to be made, analogous to the way that weather forecasters have been able to present hurricane predictions. This will require extensive efforts to engage the public over a number of years.
INTRODUCING ADAM

SYNTHETIC TRACKING TECHNOLOGY DEVELOPMENT Advancements in Telescope Technology Over the last year, B612 has supported a development project with colleagues at Caltech on a new technology called synthetic tracking for improving the capability of telescopes to discover small asteroids. The problem is that the smaller the asteroid, the closer it must be to the telescope in order to be seen. And the closer a moving object is to a telescope, the faster it transits across the field of view, resulting in a smearing of the image. Smaller asteroids are therefore even more difficult to discover because this smearing of their images makes them harder to spot against the background sky.
A constellation of such small telescopes can provide significantly better NEO tracking capability at significantly less cost than other options currently being considered. DR. ED LU, B612 CEO
Synthetic tracking uses extremely high fast data processing to enable motion compensation of moving objects, such as asteroids, in which you do not initially know the location or velocity of the still undiscovered object. This allows telescopes to take longer exposures without being subject to the reduction in sensitivity caused by the smearing of the asteroid images.
While this work is still in its early stages, we have already shown that it has great promise. We have been able to observe asteroids from a small ground based telescope that would not have been detectable without synthetic tracking. Most importantly, this opens up the possibility of using much smaller (and therefore much less expensive) telescopes than previously thought needed in the search for NEOs. In fact, a telescope capable of detecting small asteroids could be mounted on a relatively simple and inexpensive satellite. The cost of such a small satellite (SmallSat) should be roughly a hundred times less expensive than the large telescopes such as Sentinel or NEOCam needed to do a survey of >140 meter asteroids. We have already done a preliminary analysis showing that several of these small synthetic tracking satellites deployed as a constellation in Solar orbit could track the great majority of asteroids as small as Tunguska (45 meters). Before such a constellation can be considered however, it is necessary to first demonstrate the full synthetic tracking capability in space (not just on the ground).

SYNTHETIC TRACKING TECHNOLOGY DEVELOPMENT
A project to catalog asteroids smaller than 140 meters using synthetic tracking could be carried out in four phases:

PHASE 2
PHASE 3
PHASE 4

Phase One: Feasibility Study In the first phase of this work, we: â&#x20AC;˘â&#x20AC;&#x2C6; Showed that a constellation of fewer than eight SmallSats equipped with 15 cm synthetic tracking telescopes can find >70% of NEOs larger than 45 meters in <six years using existing and relatively inexpensive technology. The following figure shows the results of computations of asteroid detection performance for varying telescope size, number and orbit.
SYNTHETIC TRACKING TECHNOLOGY DEVELOPMENT

• Successfully implemented the synthetic tracking algorithm in hardware and showed it has sufficient computational speed to process a 4K x 4K detector with a 10 second frame rate. • Demonstrated synthetic tracking in post-processing on images taken on a ground based telescope and used this to observe NEOs that would not have been discoverable by that telescope without motion compensation. The middle photo below shows an asteroid detected using synthetic tracking that is not visible in the raw image on the left.
Phase Two: Demonstration Using Data Gathered in Space Because there are differences in observing asteroids from the ground and from in space, our next step is to demonstrate synthetic tracking on data gathered in space. In the fall of 2016 we plan to turn around an operating Earth mapping satellite to point towards deep space to observe a known asteroid. We will transmit the data to the ground, and apply the synthetic tracking algorithms to the data set to detect the asteroid.

SYNTHETIC TRACKING TECHNOLOGY DEVELOPMENT
The idea is to raise awareness of, not only the dangers of asteroids, but also the fact that we have solutions in hand to find dangerous asteroids and do something about it. TOM JONES, ASTRONAUT, B612 STRATEGIC ADVISOR, ASTEROID DAY EXPERT PANEL MEMBER
A Global Effort B612 is a founding partner and major supporter of Asteroid Day, acknowledged on June 30th of every year with asteroid experts, astronomers, astronauts and the general public participating in events across the globe. Through this effort, the scientific community comes together to share research and educate the broader public.
ASSOCIATION OF SPACE EXPLORERS
This year we were pleased to host Asteroid Day co-founder Grig Richters and three Asteroid Day summer interns at the B612 headquarters. The Asteroid Day team worked alongside the B612 Crew in the weeks leading up to the event on June 30th. There were a number of high profile press pieces this year, including an OpEd in the Guardian reiterating why we must stay vigilant for hazardous asteroid impacts. The OpEd was co-written by astronaut and ASE member Tom Jones; Brian May, Astrophysicist and guitarist from QUEEN; and B612 co-founder and B612 Board Member Clark Chapman.

ASTEROID DAY
Asteroid Day Premier Event in San Francisco For the second year, B612 and California Academy of Sciences teamed up for one of the world’s premier Asteroid Day events in San Francisco featuring a day of speakers and a night of asteroid-themed NightLife. The highlights of the day included presentations from renowned asteroid experts including Dr. Clark Chapman, planetary scientist, B612 Board Member and Asteroid Day Expert Panel member; Dr. Lynne Jones, Performance Scientist for the Large Synoptic Survey Telescope; Geoff Notkin, host of the Science Channel’s Meteorite Men and the STEM Journals; and Scott Manley, astronogamer, YouTube personality and Kerbal Space Program aficionado. California Academy’s incredible planetarium show, Incoming!, was played throughout the day and into the evening. Incoming! is narrated by George Takei and features B612’s technical expertise, along with dozens of other science advisors.
“ It was important to me to sign the 100X declaration because I believe so strongly in the need for people to be aware of asteroids. Not only aware of the dangers but of the good things that we can learn from asteroids. What we can learn and what we could possibly achieve. There are a lot of things that asteroids bring to us in the way of knowledge and to have more and more people looking and studying is important.” CAROLYN SHOEMAKER, ASTRONOMER, CO-DISCOVERER OF COMET SHOEMAKER–LEVY 9 AND ASTEROID DAY 100X SIGNATORY
“ The Committee endorsed a recommendation for the global observance of an international asteroid day annually on 30 June, to be proclaimed by the General Assembly at its 71st session later this year. An international asteroid day will raise public awareness of the asteroid impact hazard and inform the public of global communication measures in case of a credible near-Earth object threat.” UNITED NATIONS OFFICE FOR OUTER SPACE AFFAIRS (UNOOSA), PRESS RELEASE FROM JUNE 21, 2016
“ Our goal is to dedicate one day each year to learn about asteroids, the origins of our universe, and to support the resources necessary to see, track and deflect dangerous asteroids from Earth’s orbital path. Asteroids are a natural disaster we know how to prevent.” BRIAN MAY, QUEEN GUITARIST, ASTEROID DAY CO-FOUNDER AND B612 STRATEGIC ADVISOR
