More big space news to start the new year.
A NASA spacecraft has gone into orbit around an ancient asteroid, setting a pair of records.
The Osiris-Rex spacecraft entered orbit Monday around the asteroid Bennu, 70 million miles (110 million kilometers) from Earth.
It's the smallest celestial body ever to be orbited by a spacecraft.
Bennu is just 1,600 feet (500 meters) across.
The spacecraft's laps are barely a mile (1.6 kilometers) above the asteroid's surface, another record.
NASA's OSIRIS-REx spacecraft has found water locked deep inside the asteroid it hopes to bring a sample from back to Earth.
The craft finally arrived at asteroid Bennu last month, more than two years after blasting off from Cape Canaveral Air Force Station.
Now, NASA says it 'made the right decision' choosing its target.
'Recently analyzed data from NASA's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu,' NASA said.
'The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study the composition of primitive volatiles and organics,' said Amy Simon, OVIRS deputy instrument scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
'When samples of this material are returned by the mission to Earth in 2023, scientists will receive a treasure trove of new information about the history and evolution of our solar system.
