NASA Just Arrived at an Asteroid! SciShow News

NASA's Osiris Rex spacecraft has reached the asteroid Bennu after a two-year journey. Bennu is valuable for understanding the solar system's formation due to its proximity and chemical composition. Osiris Rex will collect samples using a nitrogen gas jet and return them to Earth by 2023. Meanwhile, new research suggests a potential fifth RNA base, Innocine, which could have played a role in early life on Earth. This discovery may expand the search for life beyond Earth.
