This weekend will see the landing of NASA’s first asteroid sample return mission, OSIRIS-REx. The spacecraft visited asteroid Bennu to study, photograph, and scoop up a sample from it, and now OSIRIS-REx is on it’s way back to Earth and is almost here.
As the spacecraft approaches, telescopes on the ground have been able to track it, even though the craft is just a few meters across — or about the size of a van. This week, an image was released by the European Space Agency from its Optical Ground Station telescope in Tenerife, Spain, showing the incoming spacecraft.
