NASA has selected 28 scientists for participation in the
2003 Mars Exploration Rover (MER) Mission. The mission
consists of two separate, though identical, rovers scheduled
for launch in mid-2003 and arrival at separate destinations
on Mars in early 2004.

The selected proposals were judged to have the best science
value among 84 proposals submitted to NASA last December in
response to the Mars Exploration Rover Announcement of
Opportunity. Each selected investigation will work with the
MER Program Office at NASA’s Jet Propulsion Laboratory (JPL),
Pasadena, Calif., and will become full MER science-team
members, joining previously selected scientists as part of
the Athena science team.

“The breadth, scope, and creativity of the scientists
selected is very encouraging,” said Dr. Ed Weiler, NASA
Associate Administrator for Space Science, Headquarters,
Washington. “By directly participating in NASA’s next mission
to the surface of Mars, they will help bring us closer to the
long-term objective of our Mars Exploration Program —
understanding Mars as a planet and determining whether life
ever existed there.”

The MER mission science objectives include: (1) study rocks
and soils for clues to past water activity; (2) investigate
landing sites that have a high probability of containing
evidence of the action of liquid water; (3) determine the
distribution and composition of minerals, rocks and soils
surrounding the landing sites; (4) determine the nature of
local surface geologic processes; (5) calibrate and validate
data from orbiting missions at each landing site; and (6)
study the geologic processes for clues about the
environmental conditions that existed when liquid water was
present, and whether those environments were conducive for
