Because the times count precise down to NASA’s OSIRIS-REx spacecraft’s Touch-And-Lag asteroid pattern sequence strive, Southwest Learn Institute scientists safe helped pick what the spacecraft can build a query to to arrive serve from the arrive-Earth asteroid Bennu’s surface. Three papers published online by Science on Oct. 8 discuss the color, reflectivity, age, composition, foundation and distribution of supplies that make up the asteroid’s tough surface.
On October 20, the spacecraft will tumble to the asteroid’s boulder-strewn surface, touch the ground with its robotic arm for a couple of seconds and accumulate a pattern of rocks and dirt — marking the first time NASA has grabbed items of an asteroid for return to Earth. SwRI scientists played a arrangement within the preference of the pattern sites. The main strive will be made at Nightingale, a rocky dwelling 66 feet in diameter in Bennu’s northern hemisphere. If this historic strive is unsuccessful, the spacecraft will strive again at a secondary blueprint.
