NASA’s OSIRIS-REx today made its official rendezvous with a promising and potentially perilous asteroid named Bennu, after two years of closing in on it.
“We have arrived,” telecommunications engineer Javi Cerna announced during a NASA webcast from mission control at Lockheed Martin Space in Colorado.
It’s a major step in OSIRIS-REx’s mission to study a near-Earth object at close range and snag samples for return to Earth in 2023.
The car-sized spacecraft has been creeping up on the 0.3-mile-wide (half-kilometer-wide), diamond-shaped space rock for weeks, but today a 28-second thruster firing stabilized its position at a point less than 12 miles (20 kilometers) away from the asteroid (and more than 75 million miles or 121 million kilometers from Earth).
