The Origins Spectral Interpretation Resource Identification Security -- Regolith Explorer spacecraft will travel to a near-Earth asteroid, called 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.

Simple and complex versions included.

NASA will launch the spacecraft 2016 and use a robotic arm to pluck samples that could better explain our solar system's formation and how life began. The mission will be the first U.S. mission to carry samples from an asteroid back to Earth augmenting the two Japanese Hayabusa missions. After traveling three years, OSIRIS-REx will approach the primitive, near Earth asteroid Bennu in 2019. Once within three miles of the asteroid, the spacecraft will begin six months of comprehensive surface mapping. The science team then will pick a location from where the spacecraft's arm will take a sample. The spacecraft gradually will move closer to the site, and the arm will extend to collect more than two ounces of material for return to Earth in 2023.

Bennu averages about 500 meters in diameter or roughly the size of five football fields. The asteroid, little altered over time, is likely to represent a snapshot of our solar system's infancy. The asteroid also is likely rich in carbon, a key element in the organic molecules necessary for life. Organic molecules have been found in meteorite and comet samples, indicating some of life's ingredients can be created in space; scientists want to see if they also are present on Bennu.

Still trying to figure out how to get an image uploaded. Put in two and ended up with other random files attached to the page. Can't seem to delete the earlier try so there's two copies up for now ...
