✌️ Happy #TwosDay... FROM SPACE! Millions of miles from Earth, two asteroids are orbiting around each other—and we've got a date with one of them. Our Double Asteroid Redirection Test lifted off last fall, destined for the 530-foot-wide (160-meter) "moonlet" Dimorphos. #DARTMission will collide with Dimorphos, very slightly adjusting its trajectory around the much larger asteroid Didymos. Neither Dimorphos or Didymos pose any potential threat to Earth—but studying exactly how Dimorphos's orbit changes will help us to design larger, more powerful spacecraft that could nudge any future threatening asteroids far out of Earth's way. This clip is a visualization of Didymos and Dimorphos created by @johnshopkinsapl, the managing facility for the DART mission. DART is scheduled to make impact with Dimorphos in late September 2022.
