SUMMARY: NASA has selected two new concepts to advance the search for extrasolar planets; one of the technologies will eventually be selected for the Terrestrial Planet Finder mission. The first choice involves the use of an Infrared Interferometer, where multiple spacecraft will simulate a much larger observatory and search for the infrared signature of a planet around a distant star. The other concept is a Visible Light Coronagraph; a telescope 4 times as large and 10 times as powerful as Hubble, capable of imaging distant planets directly. NASA will choose one path in 2005-2006.
