NASA's space probe, "Osiris-Rex", transported a valuable cargo to Earth: substance from an extraterrestrial celestial body. The probe had previously visited the dangerous asteroid “Bennu” and collected material there that is of particular importance for science.
Asteroids are considered relics from the early days of the solar system and could provide valuable information about that era. It is debated whether they were the source of water or even the basis of life on earth. Was asteroid ‘BennU’ a fragment of an ancient ocean world?.
