Before the European Space Agency astronaut Alexander Gerst, the International Space Station (ISS) landed safely on Earth on Sunday, he had time to conduct a microgravity demonstration of a historic landing on comet 67P / Churyumov-Gerasimenko.
Using the inactive microsatellite sphere (which is currently being tested on the ISS) as a comet, Gerst uses an velcro to simulate a landing. This is the only place, with the exception of computer simulation and parabolic flights, where you can really recreate a large-scale landing model.
