![]() These systems guided the 1,260-pound (570-kilogram) box-shaped spacecraft through the final 56,000 miles (90,000 kilometers) of space into Dimorphos, intentionally crashing into it at roughly 14,000 miles (22,530 kilometers) per hour to slightly slow the asteroid’s orbital speed. The spacecraft’s sole instrument, the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), together with a sophisticated guidance, navigation and control system that works in tandem with Small-body Maneuvering Autonomous Real Time Navigation (SMART Nav) algorithms, enabled DART to identify and distinguish between the two asteroids, targeting the smaller body. Just a small change in its speed is all we need to make a significant difference in the path an asteroid travels.” “Now we know we can aim a spacecraft with the precision needed to impact even a small body in space. ![]() “Planetary Defense is a globally unifying effort that affects everyone living on Earth,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. Researchers expect the impact to shorten Dimorphos’ orbit by about 1%, or roughly 10 minutes precisely measuring how much the asteroid was deflected is one of the primary purposes of the full-scale test. The investigation team will now observe Dimorphos using ground-based telescopes to confirm that DART’s impact altered the asteroid’s orbit around Didymos. The mission’s one-way trip confirmed NASA can successfully navigate a spacecraft to intentionally collide with an asteroid to deflect it, a technique known as kinetic impact. Neither asteroid poses a threat to Earth. It orbits a larger, 2,560-foot (780-meter) asteroid called Didymos. “As NASA studies the cosmos and our home planet, we’re also working to protect that home, and this international collaboration turned science fiction into science fact, demonstrating one way to protect Earth.”ĭART targeted the asteroid moonlet Dimorphos, a small body just 530 feet (160 meters) in diameter. “At its core, DART represents an unprecedented success for planetary defense, but it is also a mission of unity with a real benefit for all humanity,” said NASA Administrator Bill Nelson. EDT.Īs a part of NASA’s overall planetary defense strategy, DART’s impact with the asteroid Dimorphos demonstrates a viable mitigation technique for protecting the planet from an Earth-bound asteroid or comet, if one were discovered. Mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, announced the successful impact at 7:14 p.m. Is this a time-lapse? Because earth seems to be rotating quite fast from just 250 miles up.After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted its asteroid target on Monday, the agency’s first attempt to move an asteroid in space. Thanking NASA for the visual treat, one user wrote, ''Mesmerizing!!! Wish I could see that too with my eyes not just through pic or videos.'' Another commented, ''This might be the most beautiful video I've seen. Since being posted, the clip has accumulated 80 lakh views, 7.4 lakh likes and more than 2000 comments. Internet users were mesmerised after watching the stunning clip and expressed their delight in the comments section. ''Let you imagine yourself as a station crew member with an hour off duty and nothing better to do than look out the window as the world, literally, passes by,'' the caption reads further. ![]() ![]() Notably, the ISS which orbits the Earth at a height of 409 km, completes one revolution of Earth in 90 minutes. A post shared by NASA the caption, NASA also provided more information saying that the ultra-high definition video scenes were captured between March 2022 and March 2023 during the International Space Station's Expeditions 67 and 68.
