'My lens cover isn't off yet, but I just had to show you a first look at my new home.' While NASA has numerous Mars landings under its belt, similar attempts have proved a difficult hurdle for many missions. The Soviet Union never managed to land on Mars, and both attempts by the European Space Agency flopped. By contrast, just one of Nasa's previous eight attempts have failed. The new InSight lander has landed in a region known as Elysium Planitia.
