Terrestrial Planet Finder

(plan for space telescopes to find smaller exoplanets)

The Terrestrial Planet Finder (TPF) was a NASA plan for one or more spacecraft designed to find Extra Solar Planets. One plan was for multiple telescopes, possibly on separate spacecraft to function as an Interferometer. The other was for a single larger telescope, larger than Hubble Space Telescope, with a Coronagraph to block starlight. Congress canceled funding 2007 and NASA canceled the project in 2011.
