It’s a win-win situation, and all we have to do is get moving.

The B612 Foundation is a group of scientists, engineers, and astronauts who want to literally save the world… from asteroid impacts.
 They know the first step in doing so is to build a telescope that can spot space rocks, map their orbits, and compile a list of potential Earth-whackers. Their Sentinel mission will do just that: It will circle the Sun near the orbit of Venus, surveying the sky to look for potentially threatening rocks (it will actually do some of its best prospecting right after launch, while it’s still near Earth). The mission is ambitious, and funded through private donations.
 That’s where you come in.
