Group of former astronauts and scientists wants to launch space telescope to track asteroids headed for planet Earth
Since its birth, the California-based B612 Foundation, named after the home asteroid of the Earth-visiting prince in Antoine de Saint-Exupery's The Little Prince, has focused on finding ways to deflect an incoming asteroid. Ideas include sending an intercepting spacecraft to aiming a nuclear bomb, but none have been tested. Last year, the group shifted focus to seek out asteroids with a telescope. It is working with Ball Aerospace & Technologies Corporation, which has drawn up a preliminary telescope design. Read more
The $US200 million Sentinel telescope, when launched in 2017, will become the first privately funded deep space probe ever. Designed by the Ball Aerospace and Technologies Corporation, the same folks that brought us the Kepler and Spitzer telescopes, the Sentinel shares much of their technologies. The Sentinel employs an HD camera made up of multiple, smaller detectors to scan 165 square degrees per hour for moving objects around 50m in diameter. This will allow scientists to generate a map of our celestial neighbourhood and begin calculating the orbits of nearby asteroids, creating an early warning system of sorts. Read more
Asteroid hunters announce private deep space mission
Details have been released of an ambitious asteroid-hunting mission that a Californian non-profit organisation hopes to launch later this decade. The Sentinel infrared telescope would be put in space to find and track potentially hazardous rocks near Earth. The B612 Foundation project will cost several hundred million dollars, and big donations are being sought from around the world to fund the exercise. Read more
