NASA prepares to sample an asteroid

0
In 2020, after 18 months of observations, OSIRIS-REx will swoop close to Bennu and extend a long robotic arm equipped with its sample-collecting instrument, called TAGSAM. With a puff of nitrogen gas, it will blow some material off the asteroid's surface, gathering as much as 4.4 pounds of rock in the head of the sample.
