Space exploration

A Hubble Space Telescope image of the globular star cluster, Messier 4. The cluster is a dense collection of several hundred thousand stars. Astronomers suspect that an intermediate-mass black hole, weighing as much as 800 times the mass of our Sun, is lurking, unseen, at its core. Credits: ESA/Hubble, NASA

Members of NASA’s OSIRIS-REx curation team work with a glove box at the agency's Johnson Space Center in Houston. The curation team will be among the first to see and handle the sample OSIRIS-REx is returning from asteroid Bennu. They are also responsible for storing and distributing the sample to science team members around the world. Most of the sample will be stored for future generations.
