Terrestrial Planet Finder

The Terrestrial Planet Finder (TPF) was a proposed project by NASA to construct a system of telescopes for detecting extrasolar terrestrial planets. TPF was postponed several times and finally cancelled. There were actually two telescope systems under consideration, the TPF-I, which had several small telescopes, and TPF-C, which used one large telescope.

Famous quotes containing the word planet:

    “Until they saw, over the mists
    of Venus, two fish creatures stop
    on spangled legs and crawl
    from the belly of the sea.
    And from the planet park
    they heard the new fruit drop.”
    —Anne Sexton (1928–1974)
