NOTE TO EDITORS/NEWS DIRECTORS:

GLENN SCIENTIST SHARES EXPERIENCES WITH THE MARS EXPLORATION ROVER MISSION

Glenn Research Center scientist Dr. Geoffrey Landis will share his experience of being at the Jet Propulsion Laboratory for the two successful rover landings and talk about his study involving the rovers on Thursday, February 19, at 1 p.m. in Glenn's Visitor Center.

Landis is the principal investigator for the "Study of Solar Energy and Dust Accumulation on the Rovers," one of 28 scientific studies of Mars selected for the mission. He is interested in how much energy solar cells will be able to generate under Mars' sunlight and how dusty a solar array can get before the rovers begin to lose power. Determining the efficiency of solar cells is critical to powering the computers that control the rovers and scientific instruments that send and retrieve data from Earth.

Media representatives interested in coming to Glenn for this event should contact Sally Harrington or the Media Relations Office at 216-433-2901 by noon on Thursday, February 19, so they can be cleared through security.
