We’re experts working with NASA to deflect asteroids from impacting Earth. Ask us anything!
UPDATE: Thanks for joining our Reddit AMA about DART! We're signing off, but invite you to visit http://dart.jhuapl.edu/ for more information. Stay curious!
Join experts from NASA and the Johns Hopkins University Applied Physics Lab (APL) for a Reddit ‘Ask Me Anything’ on Monday, April 22, at 11:30 a.m. EDT about NASA's Double Asteroid Redirection Test. Known as DART for short, this is the first mission to demonstrate the kinetic impactor technique, which involves slamming a spacecraft into the moon of an asteroid at high speed to change its orbit. In October 2022, DART is planned to intercept the secondary member of the Didymos system, a binary Near-Earth Asteroid system with characteristics of great interest to NASA's overall planetary defense efforts. At the time of the impact, Didymos will be 11 million kilometers away from Earth. Ask us anything about the DART mission, what we hope to achieve and how!
