The B612 Foundation believes we should find threatening asteroids before they find us. Today’s meteor explosion over Chelyabinsk is a wake-up call that the Earth orbits the Sun in a shooting gallery of asteroids, and that these asteroids sometimes hit the Earth. Later today, a separate and larger asteroid, 2012 DA14, narrowly missed the Earth passing beneath the orbits of our communications satellites. We have the technology to deflect asteroids, but we cannot do anything about the objects we don’t know exist. To date, less than 1% of asteroids larger than the one that leveled Tunguska in 1908 have been tracked. The B612 Foundation Sentinel Space Telescope, to be launched in 2018, will provide a comprehensive map of the locations and trajectories of threatening asteroids and will give humanity the decades of warning needed to prevent asteroid impacts with existing technology. By the end of its planned lifetime, Sentinel will have discovered well over 90% of the asteroids that could destroy entire regions of Earth on impact (those larger than 350ft in diameter) and more than 50% of the currently unknown DA14-like near-Earth asteroids.

The B612 Foundation has undertaken this Sentinel project as a non-governmental initiative, somewhat akin to a growing number of private space ventures originated in the past few years. The foundation, however, is not undertaking this project for profit; we are a non-profit corporation. Our motivation is strictly to ensure the survival of life on Earth – all of it. And while NASA is cooperating with us by providing certain communication and analytic services, we are excited, as a private venture, to welcome the participation of all the crew of Spaceship Earth in this great endeavor.

Does the crew of Spaceship Earth raise our awareness and accept responsibility for our voyage into the future? Or do we sit back as passengers, comfortably assuming that there must be a captain and crew doing this job on our behalf?

The B612 Sentinel mission is testament to our belief that we, together, are responsible for the future of life on our small planet; we invite you to join us in addressing this cosmic challenge.

Prototype Sensors – B612's Next Contract with Ball Aerospace

A couple of weeks ago, I shared with you the great news that our all-star Sentinel Standing Review Team (SSRT) had carefully reviewed our technical and management plans and found that we are on track towards a successful mission.

However, one of the main recommendations was that before we sign a comprehensive contract with Ball Aerospace to build Sentinel that we go ahead and build prototype versions of our Infrared Imaging Sensors and test them to ensure they perform as expected. The ability of these infrared sensors to operate at 40 degrees Kelvin with unprecedented low noise levels is critical to the success of Sentinel.

So we have executed a contract with BALL Aerospace, under the leadership of John Troeltzsch, to build and characterize a prototype infrared imaging sensor, which will be a smaller version of the final detector (which is an enormous 12” x 4” sensor).

You can read more about this in the joint press release issued today. This is one of several critical first steps before we commit to the full spacecraft design and manufacturing contract with BALL that will be signed under a fixed-price agreement. Getting the components and design right, prior to entering into the larger strategic contract, is crucial to our long-term success.

As we head into the last months of the year, we look forward to sharing with you our B612 end-of-the-year campaign efforts, along with additional updates on our progress and most importantly, how you – our crew members – can help to continue to secure support for the mission.
