OSIRIS-REx is an ongoing mission. It returned samples of asteroid Bennu to Earth on Sept. 24, 2023, and is now moving on to study asteroid Apophis in 2029.

NASA OSIRIS-REx asteroid sample return team has revealed exciting evidence of the precursors of life in the pieces of space rock Bennu.

A piece from NASA's OSIRIS-REx asteroid mission samples has been unveiled at the Smithsonian's Natural History Museum.

2029: OSIRIS-REx begins extended mission to asteroid Apophis. OSIRIS-REx was carried into space atop an Atlas V rocket from Cape Canaveral, Florida. Why did OSIRIS-REx go to Bennu?

NASA's OSIRIS REx mission cost $1.16 billion for just under 9 ounces of asteroid dust. But it's hardly the most expensive material in science. Here's where it ranks.

OSIRIS-REx: To Bennu and Back is a local public television program presented by AZPM.

The seven-year Osiris-Rex mission ended on Sunday with the return of regolith from the asteroid Bennu, which might hold clues about the origins of our solar system and life.

This could explain the pebbles present in Aguas Zarcas, making the meteorite the first physical evidence of the geological process observed by OSIRIS-REx on Bennu.

The instruments on the OSIRIS-REx spacecraft made observations of reflected light that revealed the most abundant minerals and organics when it was near asteroid Bennu.

“From OSIRIS-REx we know that these particle ejection events are much more frequent than these high-velocity impacts,” said Heck, “so they probably play a more important role in determining the makeup ...
