Whole New Mercury Promised by NASA Spacecraft

NASA will hold a press conference today (Sept. 29) to unveil the latest discoveries on Mercury by a spacecraft orbiting the small rocky planet.

The NASA teleconference is set for 2 p.m. EDT (1800 GMT) and will reveal new details about Mercury observed by the space agency's Messenger spacecraft. The unmanned probe arrived at Mercury on March 17 and is the first spacecraft ever to orbit the innermost planet of the solar system.  [Messenger's latest photos of Mercury]

Several Messenger mission scientists will give presentations during today's teleconference, NASA officials said in a statement. They include:

  • Ed Graykzeck, Messenger program manager, NASA Headquarters, Washington
  • James Head, III, professor of geological sciences, Brown University
  • David Blewett, Messenger participating scientist and staff scientist, Johns Hopkins University Applied Physics Laboratory (APL), Laurel, Md.
  • Patrick Peplowski, staff scientist, APL
  • Thomas Zurbuchen, professor of space science and aerospace engineering, University of Michigan

NASA's $446 million Messenger mission to Mercury launched in 2004 on a 6 1/2-year journey to innermost planet. The spacecraft's name is short for the bulky moniker MErcury Surface, Space ENvironment, GEochemistry, and Ranging.

Since entering orbit around Mercury, the Messenger has been continuously snapping photos of the planet's stark, rocky surface, as well as using other instruments to study the planet's interior and tenuous atmosphere.

NASA will post information on how to listen in on the Mercury teleconference today here.
