Launch Date	Sept. 8, 2016 \| 23:05 UT
Launch Site	Cape Canaveral, Florida, USA
Destination	Asteroids, 101955 Bennu
Type	Orbiter, Sample Return
Status	In Progress
Nation	United States

Goals

Travel to a near-Earth asteroid Bennu (formerly 1999 RQ36), and bring at least a 2.1-ounce sample back to Earth for study. The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth.

Accomplishments

This spacecraft is en route to its primary destination.

A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA’s Opportunity rover to suspend science operations. But across the planet, NASA’s Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust.
