OSIRIS-REx asteroid Bennu mission
OSIRIS-REx ready for pre-ship review

Physicist: For this mission, due to launch soon, I can not do better than quote the description on the NASA mission page and provide three links:

OSIRIS-REx will travel to a near-Earth asteroid called Bennu and bring a small sample back to Earth for study. The mission is scheduled to launch Sept. 8, 2016. As planned, the spacecraft will reach its asteroid target in 2018 and return a sample to Earth in 2023.
