The spacecraft - which is the size of a compact car - was destroyed, but the collision was documented by a small satellite called LICIACube that trailed behind. The space rock - which is some 6.5 million miles from Earth - holds no threat to the planet, but is a perfect subject to test a new system that could knock a dangerous asteroid off course, scientists say.ĭART smashed into Dimorphos and successfully knocked it out of its 12-hour orbit, scientists say. “A giant leap for humanity in the name of planetary defense.” “We have impact!” one of NASA news editor’s Samson Reiny said in the live video. in an event that was live streamed by the space agency on its website. The room of NASA scientists and engineers erupted in cheers and applause as the spacecraft made impact. The Double Asteroid Redirection Test (DART) collided with a 530-foot-wide interplanetary body named Dimorphos at 7:14 p.m. NASA practiced saving the Earth by ramming the vending-machine-sized spacecraft into an asteroid in an attempt to prove it can deflect planet-threatening space rocks. ![]() NASA successfully crashed a spacecraft into an asteroid at 15,000 miles per hour Monday night in a test run to prepare for when a massive space rock actually threatens Earth. Not just balloons: Here’s how China spies on the US Piece of sun breaks off, stuns scientists: ‘Very curious’ Engineers and curation experts are designing specialized gloveboxes, tools, and storage containers to preserve the sample in pristine condition.Solar storm speeding toward Earth could affect radio, GPS signalsĬuriosity Mars rover finds ‘best’ evidence of water in rippled rocks NASA's Johnson Space Center in Houston built a new curation lab specifically to store the sample. NASA is working closely with the Air Force and Army to practice capsule retrieval and transport to onsite facilities at the Utah range. With just less than a year to go, the mission team is already preparing for the sample's arrival.

After releasing the sample return capsule on Sept. This video displays the orbit of OSIRIS-REx returning to Earth with its sample of asteroid Bennu. A series of maneuvers beginning in July 2023 will bring OSIRIS-REx even closer, to 155 miles (250 kilometers) off the surface, close enough to release its sample capsule for a precision landing-via parachute at the Air Force's Utah Test and Training Range in the Great Salt Lake Desert. Following this course adjustment, OSIRIS-REx would pass about 1,367 miles (2,200 kilometers) from Earth. Last month's maneuver was the first time the OSIRIS-REx team changed the spacecraft's trajectory since it left Bennu on May 10, 2021. ![]() "We have to cross Earth's orbit at the time that Earth will be at that same location." Wibben works closely with the Lockheed Martin team in Littleton, Colorado, that flies the spacecraft. To ensure a safe delivery, "Over the next year, we will gradually adjust the OSIRIS-REx trajectory to target the spacecraft closer to Earth," said Daniel Wibben, trajectory-and-maneuver design lead with KinetX Inc. "Angled too low, it will burn up in Earth's atmosphere." "If the capsule is angled too high, it will skip off the atmosphere," said Mike Moreau, OSIRIS-REx deputy project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The delivery itself, however, is not a simple parcel drop on Earth's front doorstep: NASA's OSIRIS-REx-formally the Origins Spectral Interpretation Resource Identification Security-Regolith Explorer-must approach Earth at a precise speed and direction to deliver its sample return capsule into Earth's atmosphere. ![]()
