The ill-fated Beagle 2 probe, released from the Mars Express spacecraft on December 19, stops transmitting shortly before its scheduled landing.
The Beagle 2 is an inoperative British Mars lander that was transported by the European Space Agency's 2003 Mars Express mission. It was intended to conduct an astrobiology mission that would have looked for evidence of past life on Mars.
The spacecraft was successfully deployed from the Mars Express on 19 December 2003 and was scheduled to land on the surface of Mars on 25 December. ESA, however, received no communication from the lander at its expected landing time on Mars, and declared the mission lost in February 2004 after numerous attempts to contact the spacecraft were made.The Beagle 2's fate remained a mystery until January 2015, when it was located on the surface of Mars in a series of images from NASA's Mars Reconnaissance Orbiter HiRISE camera. The images showed it landed safely but two of its four solar panels failed to deploy, blocking the spacecraft's communications antenna.
The Beagle 2 is named after HMS Beagle, the ship that took the naturalist Charles Darwin on his round-the-world voyage.
