From the "science lost" files: Beagle-2 spacecraft discovered on Martian surface
Lost since 2003, the UK-led Beagle-2 Mars lander has finally been discovered on the Martian surface by NASA's Mars Reconnaissance Orbiter (MRO). Analysis of the images revealed that the lander survived its Dec. 25, 2003 touchdown, partially deploying on the surface of the Red Planet. No signal was received from the lander following its expected landing time, and the robotic explorer was feared destroyed.
