Landing in a comet

The European Space Agency put a 98 kg space probe in the surface of the comet 67P/Churyumov–Gerasimenko. The Philae probe bounced back into space a couple of times before landing, since the escape velocity from the comet is only 1.8 km/h. Science went well till Philae batteries exhausted. The Rosetta spacecraft will continue monitoring the comet for at least one year. More results to come.

The orbital approach to the comet is shown in the video below.
