New Frontiers program
OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer ) was a NASA asteroid-study and sample-return mission.[10]
The mission collected samples from 101955 Bennu , a carbonaceous near-Earth asteroid , and returned the samples to earth in September 2023.[11]
The material returned is expected to enable scientists to learn more about the formation and evolution of the Solar System , its initial stages of planet formation, and the source of organic compounds that led to the formation of life on Earth.[12]
OSIRIS-REx is the first United States spacecraft to return samples from an asteroid.
