Behind the Spacecraft: Kelly Fast

NASA planetary defender Dr. Kelly Fast has a hard and fast rule: “Find asteroids before they find us.” Working in NASA’s Planetary Defense Coordination Office, Kelly is helping send a first-of-its-kind mission to test what it would take to “nudge” an asteroid in space. Find out more about the #DARTmission: www.nasa.gov/DART

The DART mission is a test of a technique that could be used to mitigate the threat of an asteroid on a collision course with Earth should one be discovered in the future. DART’s target is not a threat to Earth. While no known asteroid larger than 140 meters in size has a significant chance to hit Earth for the next 100 years, only about 40 percent of those asteroids have been found as of October 2021.
