A remarkable feat in human history has been achieved by European Space Agency (ESA) when Rosetta mission’s Philae lander landed on a comet successfully.
This achievement is not only a great achievement for ESA but it can be useful for space science and technology in general as now humanity knows that it is doable!
Congratulations ESA and all the scientists, engineers and everyone involved with the mission.
