Schweickart Prize Winner Joe DeMartini on Hunting for Asteroids in the Sun’s Shadow to Defend Earth

Joe DeMartini is the first recipient of the Schweickart Prize, awarded by the B612 Foundation for his innovative proposal to detect and track asteroids during twilight hours. Joe’s proposal could significantly enhance planetary defence by locating asteroids in the large section of the sky that’s difficult for telescopes to observe because of the sun’s light. Joe talks about the details of his proposal, about meeting Apollo 9 astronaut Rusty Schweickart who founded the B612 Foundation, and about the asteroid Apophis which will pass between Earth and the moon in just under 5 years, on April 13, 2029.
