Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, which is the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. Launched in 2009, the Kepler space telescope is detecting planets and planet candidates with a wide range of sizes and orbital distances to help us better understand our place in the galaxy.

The briefing participants are:

-- Paul Hertz, astrophysics director, NASA Headquarters, Washington
-- Roger Hunter, Kepler project manager, Ames Research Center, Moffett Field, Calif.
-- William Borucki, Kepler science principal investigator, Ames Research Center
