With the OSIRIS-REx space probe, the NASA space agency succeeded in collecting some material from the surface of asteroid Bennu, which arrived on Earth in a small capsule in 2023. The analysis of the material by more than 40 scientific teams worldwide – including the team led by Prof. Frank Brenker from Goethe University – revealed a number of organic substances that form the basis for biomolecules. In addition, the minerals in the sample also indicate that the protoplanet from which Bennu originated once had liquid, salty water. Thus, this protoplanet possessed both ingredients for life and potential habitats.
