NASA's first asteroid samples land on Earth after release from spacecraft
- NASA has successfully returned the largest soil sample from the asteroid Bennu to Earth. This sample is composed of the original materials of the solar system and is considered a relic of the early solar system.
- The hypothesis is that asteroids and comets delivered organic material and potentially water to Earth, which helped life flourish here. Bennu, a carbon-rich asteroid, is believed to contain water molecules locked in minerals and has a low density.
- NASA will use a quarter of the sample immediately for experiments and will share small amounts with mission partners. The majority of the sample will be saved for future scientific analysis.
