NASA to Announce New Planetary Science Mission Today
WASHINGTON -- NASA will host a media teleconference at 5 p.m. EDT today to discuss the selection of a new Discovery-class mission that will further NASA's exploration of the solar system. The selection will be the 12th in NASA's series of Discovery-class missions.

The panelists for the briefing are:

Created in 1992, the Discovery Program sponsors frequent, cost-capped solar system exploration missions with highly focused scientific goals. In May 2011, NASA selected three mission concepts from 28 proposals for funding to conduct preliminary design studies and analyses.

Recent Discovery missions include MESSENGER, Dawn, Stardust, Deep Impact and Genesis. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the program for the agency's Science Mission Directorate.
