On August 6, 2013, NASA celebrated "Curiosity" first year on Mars (August 6, 2012 to August 5, 2013) by programming the rover to perform the "Happy Birthday" song to itself.

Mars landing after Pillinger's death. The lander appears to have successfully landed but not deployed all of its power and communications panels. Shortly after the launch of Mars Express, NASA sent a pair of twin rovers toward the planet as part of the Mars Exploration Rover mission.
