Breaking down Bennu: OSIRIS-REx finds life’s building blocks in asteroid sample

NASA’s OSIRIS-REx mission has returned pristine samples from asteroid Bennu to Earth, and the early results are remarkable. Sample analysts have confirmed the presence of abundant organic compounds, nitrogen-rich material, and evidence of past liquid water, all key ingredients that could help us understand the role asteroids played in delivering the building blocks of life to Earth. This week, we’re joined by Scott Sandford, co-investigator on OSIRIS-REx and a research scientist at NASA’s Ames Research Center. He explores the first two sample analysis papers published by NASA’s OSIRIS-REx team. Then, Bruce Betts joins us for What’s Up, where we look back at humanity’s history of sample return missions.
