The Kepler telescope
- Like the French mission Corot, NASA's project, called Kepler , will observe star fields (60000 in the case of Corot and 100000 for Kepler) with a very high photometric precision, in order to detect hundreds of earth-type planets. This space telescope will be launched in 2008.
Darwin : Darwin is an ESA mission. It is made up of 8 space vehicles designated to discover some planets comparable to the Earth, and analyse their atmospheres in order to eventually detect the chemical signature of life. 6 vehicles will take telescopes with diameters of at least 1.5 meters. The seventh vehicle will combine the light of the first 6 telescopes and will thus simulate a mirror with a much bigger diameter. The eighth one will communicate with the Earth and the other instruments. Darwin is expected to be launched in 2014.
TPF : Terrestrial Planet Finder of NASA. This project consists of a network of several satellites, and will be launched around 2020.
