NASA spacecraft lands on asteriod

48

CAPE CANAVERAL — After a two-year chase, a NASA spacecraft arrived Monday at the ancient asteroid Bennu, its first visitor in billions of years.

The robotic explorer Osiris-Rex pulled within 12 miles of the diamond-shaped space rock. It will get even closer in the days ahead and go into orbit around Bennu on 31 December. No spacecraft has ever orbited such a small cosmic body.

It is the first US attempt to gather asteroid samples for return to Earth, something only Japan has accomplished so far.

Flight controllers applauded and exchanged high-fives once confirmation came through that Osiris-Rex made it to Bennu — exactly one week after NASA landed a spacecraft on Mars.

“Relieved, proud and anxious to start exploring!” tweeted lead scientist Dante Lauretta of the University of Arizona. “To Bennu and back!”
