Beagle 2
Beagle 2 was a British-led Mars lander that was part of the European Space Agency's (ESA) Mars Express mission. Here are some key points about Beagle 2:
- Launch and Mission: Beagle 2 was launched on June 2, 2003, from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz-Fregat rocket, along with the Mars Express orbiter. Its goal was to search for signs of life on Mars, past or present, by examining the Martian soil and atmosphere.
- Design: The lander was designed by a team led by Professor Colin Pillinger of the Open University. It was named after the ship HMS Beagle, which carried Charles Darwin on his famous voyage. The lander was small, roughly the size of a dinner plate, and was equipped with scientific instruments including a gas analyzer for detecting organic molecules, a microscope, a stereo camera, and various sensors for environmental analysis.
- Descent and Landing: After detaching from Mars Express, Beagle 2 was supposed to enter the Martian atmosphere and land on Christmas Day, December 25, 2003. However, initial attempts to communicate with the lander failed, leading to fears that it had crashed or failed to deploy properly.
- Discovery: It was not until January 16, 2015, that images from NASA's Mars Reconnaissance Orbiter (MRO) HiRISE camera confirmed the location of Beagle 2 on the surface of Mars. The images showed that the lander had partially deployed its solar panels but did not fully open, likely due to a failure in one of the deployment mechanisms.
- Legacy: Although Beagle 2 did not achieve its scientific objectives, the mission provided valuable lessons for future Mars exploration efforts, particularly in the areas of entry, descent, and landing technologies. The spirit of exploration and the scientific ambition of the mission remain an inspiration in the field of planetary science.
