NASA has recently announced that its OSIRIS-REx spacecraft has begun a 2.5-year journey back to Earth after reportedly collecting samples from an asteroid called Bennu. Scientists said that since asteroids are debris from the solar system's formation around 4.5 billion years ago, they could contain clues to the origins of life on Earth. Mission involves collecting asteroid samples, sending them home.
