The B612 Foundation is a private nonprofit foundation with headquarters in the United States, dedicated to protecting the Earth from asteroid strikes. It is led mainly by scientists, former astronauts and engineers from the Institute for Advanced Study, Southwest Research Institute, Stanford University, NASA and the space industry.
As a non-governmental organization it has conducted two lines of related research to help detect asteroids that could one day strike the Earth, and find the technological means to divert their path to avoid such collisions. In 2012 the foundation announced it would design and build a privately financed asteroid-finding space telescope, Sentinel, to be launched in 2017–2018. Once stationed in an orbit similar to that of Venus, Sentinel's supercooled infrared telescope will then help identify dangerous asteroids and other near-Earth objects (NEOs) that pose a risk of collision with Earth.

The B612 project grew out of a one-day workshop on asteroid deflection strategies organized by Dutch astrophysicist Piet Hut along with physicist and former U.S. astronaut Ed Lu, presented at NASA's Johnson Space Center in Houston, Texas in October 2001. The seminar participants included Rusty Schweickart, a former Apollo astronaut, and Clark Chapman, a planetary scientist. Schweickart, along with Drs. Hut, Lu and Chapman then formed the B612 Project and later established the B612 Foundation on October 7, 2002.
Schweickart was an early public face of the foundation and served as its chair on its board of directors. He had, in 2010, as part of an ad hoc task force on planetary defense, advocated increasing NASA's annual budget by $250M–$300 million over a 10 year period (with an operational maintenance budget of up to $75 million/year after that) in order to more fully catalog the NEOs that can poise a threat to Earth and to also fully develop impact avoidance capabilities. That level of budget support would permit up 10–20 years of advance warning in order to allow for a sufficient deflection capability. Their recommendations were made to a NASA Advisory Council, but were ultimately unsuccessful in obtaining Congressional funding due to NASA, lacking a legislated mandate for planetary protection, not being permitted to request it.
In 2012, the foundation began a fundraising campaign to cover the approximate US$450 million cost for the development, launch and operations of an asteroid-finding space telescope, to be called Sentinel, with a goal of raising $30 to $40 million per year.
The need for an asteroid detection program has been compared to the need for monsoon, typhoon and hurricane preparedness. The B612 Foundation is one of several organizations to propose the cataloging of near-Earth objects (NEOs) and preventative measures such as asteroid deflection; others include the international Spaceguard Foundation and NEOShield. In 2009 Anatoly Perminov, the head of the Russian Federal Space Agency, proposed a deflection mission to 99942 Apophis, which at the time had been thought to pose a risk to Earth.
|“||REP. STEWART: ... are we technologically capable of launching something that could intercept [an asteroid with 2 years of advance warning]? ...
DR. A'HEARN: No. If we had spacecraft plans on the books already, that would take a year ... I mean a typical small mission ... takes four years from approval to start to launch ...
As a result of a set of hearings by the NASA Advisory Committee following the Chelyabinsk explosion in 2013, in conjunction with a White House request to double its budget, NASA’s Near Earth Object Program funding was increased to $40.5 M/year in its FY2014 (Fiscal Year 2014) budget. It had previously been increased to $20.5 M/year in FY2012 (about 0.1% of NASA's annual budget at the time), from an average of about $4 M/year between 2002 and 2010.
Asteroid hazard reassessment
On Earth Day, April 22, 2014 the B612 Foundation formally presented a revised assessment on the frequency of "city-killer"-type impact events, based on research led by Canadian planetary scientist Peter Brown of the University of Western Ontario's (UWO) Centre for Planetary Science and Exploration. Dr. Brown's analysis, "A 500-Kiloton Airburst Over Chelyabinsk and An Enhanced Hazard from Small Impactors", published in the journals Science and Nature, was used to produce a short computer-animated video that was presented to the media at the Seattle Museum of Flight. The nearly one and a half minute video displayed a rotating globe with the impact points of about 25 asteroids measuring more than one, and up to 600 kilotons of blast force, that struck the Earth from 2000–2013 (for comparison, the nuclear bomb that destroyed Hiroshima was about equivalent to 16 kilotons of TNT blast force). Of those impacts between 2000 and 2013, eight of them were as large, or larger, than the Hiroshima bomb.
At the presentation, alongside former NASA astronauts Dr. Tom Jones and Apollo 8 astronaut Bill Anders, Foundation head Dr. Ed Lu explained that the frequency of dangerous asteroid impacts hitting Earth was from three to ten times greater than previously believed. The reassessment is based on worldwide infrasound signatures recorded under the auspices of the Comprehensive Nuclear-Test-Ban Treaty Organization, which monitors the planet for nuclear explosions. Dr. Brown's UWO study used infrasound signals generated by asteroids that released more than a kiloton of TNT explosive force. The study suggested that "city-killer"-type impact events similar to the Tunguska event of 1908 actually occur on average about once a century instead of every thousand years, as was once previously believed. The 1908 event occurred in the remote, sparsely populated Tunguska area of Siberia, Russia, and is attributed to the likely airburst explosion of an asteroid or comet that destroyed some 80 million trees over 2,150 square kilometres (830 sq mi) of forests. The new higher frequency of such events is interpreted to mean that "blind luck" has mainly prevented a catastrophic impact over an inhabited area that could kill millions, a point stated near the end of the B612 video.
The Sentinel Mission program is the cornerstone of the B612 Foundation's current efforts, with its preliminary design and system architecture level reviews planned for 2014, and its critical design review to be conducted in 2015. The infrared telescope would be launched atop a SpaceX Falcon 9 rocket, to be placed into a Venusian orbit around the Sun. Orbiting between the Sun and Earth, the sun's rays would always be behind the telescope's lens and thus never inhibit the space observatory's ability to detect asteroids or other near-Earth objects (NEOs). From the vantage of its inner-solar system Venus-like orbit, Sentinel will be able to "pick up objects that are currently difficult, if not impossible, to see in advance from Earth", such as occurred with the Chelyabinsk meteor of 2013 that went undetected until its explosion over Chelyabinsk Oblast, Russia. With the Sentinel Mission providing an accurate dynamic catalog of asteroids and other NEOs made available to scientists worldwide from the International Astronomical Union's Minor Planet Center, the data collected will calculate the risk of impact events with our planet, allowing for asteroid deflection by the use of gravity tractors to divert their trajectories away from Earth.
In order to communicate with the spacecraft while it's orbiting the sun (at about the same distance as Venus), which can be at times as far as 270 million kilometres (170 million miles) from Earth, the B612 Foundation entered into a Space Act Agreement with NASA for the use of their deep space telecommunication network.
Design and operation
Sentinel is being designed to perform continuous observation and analysis during its planned six and a half year operational life, although B612 anticipates it may continue to function for up to 10 years. Using its 51 centimetres (20 in) telescope mirror with sensors built by Ball Aerospace (makers of the Hubble Space Telescope's instruments), its mission will be to catalog 90% of asteroids with diameters larger than 140 metres (460 ft). There are also plans to catalog smaller solar system objects as well.
The space observatory will measure 7.7 metres (25 ft) by 3.2 metres (10 ft) with a mass of 1,500 kilograms (3,300 lb) and will orbit the Sun at a distance of 0.6 to 0.8 astronomical units (90,000,000 to 120,000,000 km; 56,000,000 to 74,000,000 mi) approximately the same orbital distance as Venus, employing infrared astronomy to identify asteroids against the cold of outer space. Sentinel will scan in the 7- to 15-micron wavelength band across a 5.5 by 2-degree field of view. Its sensor array will consist of 16 detectors with coverage scanning "a 200-degree, full-angle field of regard". B612, working in partnership with Ball Aerospace, is constructing Sentinel's 51 cm aluminum mirror, designed for a large field of view with its infrared sensors cooled to 40 degrees Kelvin (–233 °C) using Ball's two-stage, closed-Stirling-cycle cryocooler.
B612 aims to produce its space telescope at a significantly lower cost than traditional space science programs by making use of space hardware systems previously developed for earlier programs, rather than designing a brand new observatory. Schweickart stated that about "80% of what we’re dealing with in Sentinel is Kepler, 15% Spitzer, 5% new, higher-performance infrared sensors", thus concentrating its R&D funds on the critical area of cryogenically-cooled image sensor technology, producing what it terms will be the most sensitive type of asteroid-finding telescope ever built.
Data gathered by Sentinel will be provided through existing scientific data-sharing networks that include NASA and academic institutions such as the Minor Planet Center in Cambridge, Massachusetts. Given the satellite's telescopic accuracy, Sentinel's data may prove valuable for other possible future missions, such as asteroid mining.
Sentinel mission funding
B612 is attempting to raise approximately $450M to fund the development, launch and operational costs of the telescope, approximately $100M less than a single Next-Generation Bomber for the U.S. Air Force. The $450 million cost estimate is composed of $250 million to create Sentinel, plus another $200 million for 10 years of operations. In explaining the Foundations current bypassing of possible governmental grants for such a mission, Dr. Lu stated their public fundraising appeal is being driven by "[t]he tragedy of the commons: When it’s everybody’s problem, it’s nobody’s problem", referring to a lack of priority and funding that governments have assigned to asteroid threats, also stating on a different occasion "We’re the only ones taking it seriously." According to another B612 board member, Rusty Schweickart, "The good news is, you can prevent it — not just get ready for it! The bad news is, it's hard to get anybody to pay attention to it when there are potholes in the road." After providing earlier Congressional testimony into the issue Schweickart was dismayed to hear from congressional staff members that, while U.S. lawmakers involved in the hearing understood the seriousness of the threat, they would likely not legislate funding for planetary defense as "making the deflection of asteroids a priority might backfire in [their] reelection campaigns".
In the aftermath of the February 2013 Chelyabinsk meteor explosion—where an approximate 20 metres (66 ft) asteroid entered the atmosphere undetected at about Mach 60, becoming a brilliant superbolide meteor before exploding over Chelyabinsk, Russia —the B612 foundation experienced a "surge of interest" in its project to detect asteroids, with a corresponding increase in funding donations. After providing Congressional testimony Dr. Lu noted that the many online videos recorded of the asteroid's explosion over Chelyabinsk made a significant impact on millions of viewers worldwide, saying "There’s nothing like a hundred YouTube videos to do that."
In 2014 eight key staff positions were designated, covering the offices of the Chief Executive Officer (CEO), Chief Operating Officer (COO), Sentinel Program Architecture (SPA), Sentinel Mission Direction (SMD), Sentinel Program Management (SPM), Sentinel Mission Science (SMS) and the Sentinel Standing Review Team (SSRT), plus Public Relations.

He is currently Program Head in Interdisciplinary Studies at the Institute for Advanced Study in Princeton, New Jersey, former home to Albert Einstein.
Hut's specialization is in "stellar and planetary dynamics; many of his more than two hundred articles are written in collaboration with colleagues from different fields, ranging from particle physics, geophysics and paleontology to computer science, cognitive psychology and philosophy." Dr. Hut was an early adviser to Dr. Lu and served as a founding member of the B612 Foundation’s Board of Directors.
His education includes an M.Sc. from the University of Utrecht and a double Ph.D. in particle physics and astrophysics from the University of Amsterdam in 1977 and 1981 respectively. He is the namesource for Asteroid 17031 Piethut in honor of his work in planetary dynamics and for his co-founding of B612.
The B612 Foundation is a California 501(c)(3) non-profit, private foundation. Financial contributions to the B612 Foundation are tax-exempt in the United States. Its principal offices are in Mountain View, California; they were previously located in Tiburon, California.
The B612 Foundation is named in tribute to the home asteroid of the eponymous hero of Antoine de Saint-Exupéry's best-selling novella The Little Prince. In aviation's early pioneer years of the 1920s, Saint-Exupéry made an emergency landing on top of an African mesa covered with crushed white shells. Walking around in the moonlight he kicked a black rock and soon realized it was a meteorite that had fallen from space.
That experience later contributed, in 1943, to his literary creation of Asteroid B-612 in his philosophical fable of a little prince fallen to Earth, with the home planetoid's name having been adapted from one of the mail planes Saint-Exupéry once flew, bearing the registration marking A-612.
Also inspired by the story is an asteroid discovered in 1993, though not identified as posing any threat to Earth, named 46610 Bésixdouze (the numerical part of its designation represented in hexadecimal as 'B612', while the textual part is French for "B six twelve"). As well, a small asteroid moon, Petit-Prince, discovered in 1998 is named in part after The Little Prince.
