Life in space ESA's Mars Express is searching for signs of life around the Red Planet. Evidence about available water will help engineers to judge the practicalities of sending astronauts to Mars. We are the first inhabitants of the Earth who, by astronomy and interplanetary projects, can explore the cosmic machinery that gave us birth, and search for existing life elsewhere. But we are also capable of carrying life into space ourselves. ESA is fully engaged in the pursuit of both forms of life in space, human and alien.         Claude Nicollier repairing Hubble     Europe’s astronauts           Zarya and Unity   International Space Station         Jean-Pierre Haigneré returns from MIR     Space medicine           A lasting impression   The future of human spaceflight         Mars Express     Life on Mars?           A starry birth and death   A habitable Universe         Huygens parachutes onto Titan     Recipes for life           Hipparcos spies a massive planet   Life among the stars?         Last update: 20 April 2004 Mars Express  •  - (http://www.esa.int/SPECIALS/Mars_Express/index.html) Rosetta  •  ESA's comet chaser (http://www.esa.int/SPECIALS/Rosetta/index.html) Related links  •  ESA Science (http://www.esa.int/esaSC/index.html)  •  Human Spaceflight and Exploration (http://www.esa.int/esaHS/index.html)  •  European Astronaut Centre (http://www.esa.int/esaHS/ESAJIE0VMOC_astronauts_0.html)  •  ESA's ISS homepage (http://www.esa.int/esaHS/iss.html)  •  Space medicine for Euromir 95 (http://www.esa.int/esapub/bulletin/bullet88/daman88.htm)  •  Has space a future?
