NASA hopes OSIRIS-REx data will explain an asteroid’s mini-eruptions
NASA's OSIRIS-REx spacecraft made a startling discovery shortly after arriving at its target, a 1614-foot-wide rock called Bennu: the asteroid was ejecting particles from its surface. While that's common behavior on icy comets, it's much rarer on ast...
NASA's OSIRIS-REx team has selected four potential sites for the agency's first asteroid sample return mission. The spacecraft started mapping asteroid Bennu's surface as soon as it arrived in late 2018, and scientists part of its ground team thought...
An asteroid slightly wider than the Empire State Building has confused scientists by shooting out plumes of dust, as a new set of close-up images from NASA shows. Bennu, the near-Earth asteroid that NASA's OSIRIS-REx mission has been observing since...
After NASA's OSIRIS-REx arrived at asteroid Bennu in early December, its ground team quickly started measuring and mapping out the celestial body. They needed all the information they could get in order to enter Bennu's orbit, since the asteroid has...
It didn't take long for NASA's OSIRIS-REx spacecraft to glean valuable insights from the asteroid Bennu. The vessel has helped scientists discover water trapped inside Bennu's clays thanks to its two spectrometers, which spotted the hydroxyls (bonded...
NASA's OSIRIS-REx spacecraft has officially arrived at the asteroid Bennu after a more than two-year-long journey. The spacecraft rendezvoused with its target around noon EST, and NASA confirmed the arrival a few minutes thereafter during a live even...
The holiday season has officially kicked into high gear, which means it's time to gather around the hearth, count your blessings and quietly roll your eyes as uncle Jerry launches once again into why smoke wouldn't rise straight up if the Earth weren...
NASA's spacecraft OSIRIS-REx is just 75 miles from its destination and, just like you would near the end of a light, it's starting to stretch out. The craft successfully tested its Touch-and-Go Sample Acquisition Mechanism (TAGSAM), a robotic arm tha...
