For decades, Mars has played an important role in the Solar System research activities of the German Aerospace Center (DLR). It has become increasingly clear that Earth’s neighbour in space shared more similarities with Earth in its early days than it does today. It is therefore considered to be the planet on which the existence of life long ago – or perhaps even today – is most conceivable. DLR scientists are involved in NASA’s Mars 2020 mission with the Perseverance rover, particularly for image processing and evaluation. In this video, they explain the scientific context of the mission, the process of the extremely technically demanding landing on Mars and the geology of the landing site in the Jezero Crater.
