And a fifth is sick, but undergoing treatment. The most spectacular pictures so far have been provided by Mars Express, the European Space Agency’s contribution to the fleet. On January 28th this reached its final working orbit (which takes it over both poles, and thus allows it to see the whole of Mars over the course of a few days as the planet revolves beneath it).

C. the performance of five craft launched to Mars
