The rubble contains water, a vital puzzle piece in understanding what made 'our world habitable'
A whole treasure chest of extraterrestrial material' is still waiting to be studied, said one scientist working on the mission,hopes evidence of the creation of Earth could be present in a 4.5-billion-year-old asteroid as the agency showcased samples collected from it in space.
The samples were collected three years ago from the surface of Bennu and then dropped off in a sealed container into the Utah dessert last month. The asteroid rubble holds water in the form of water-bearing clay minerals, which he explained is "how we think water got to the Earth." The age of asteroid Bennu means the formation is remnant of our early solar system and scientists believe it can help shed light on how planets formed and evolved.
