Asteroid samples collected by NASA’s OSIRIS-REx not only contain the pristine building blocks for life, but also the salty remains of an ancient water world. The spacecraft was able to help unlock these discoveries because it collected samples directly from the asteroid and carefully preserved them on the way back to Earth. These findings support the idea that asteroids delivered the building blocks of life to our planet early in its history, and may have delivered them elsewhere in the solar system. The success of this mission justifies the development of future sample retrieval missions to other cosmic bodies within our solar system.
