NASA to Make Contact With Asteroid That Could Threaten Earth | National Geographic

NASA s OSIRIS-REx mission plans to return a sample of asteroid Bennu to Earth in 2023 so that scientists can study pristine material left over from the early solar system. With a small chance that Bennu could impact Earth late in the 22nd century, the mission will also allow scientists to study how gravity and thermal forces can alter an asteroid s orbit, helping them predict where Bennu will be in the future. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world s premium destination for science, exploration, and adventure.
