OSIRIS-REx discovers water on asteroid, confirms Bennu as excellent mission target
(PHYSorg.com Space & Earth)

From August through early December, the OSIRIS-REx spacecraft aimed three of its science instruments toward Bennu and began making the mission`s first observations of the asteroid. During this period, the spacecraft traveled the last 1.4 million miles (2.2 million km) of its outbound journey to arrive at a spot 12 miles (19 km) from Bennu on Dec. 3. The science obtained from these initial observations confirmed many of the mission team`s ground-based observations of Bennu and revealed several new surprises.
