NASA SELECTS PROPOSALS FOR FUTURE MARS MISSIONS AND STUDIES
WASHINGTON - On Monday, NASA selected for concept study development
two proposals for future robotic missions to Mars. These missions
would increase understanding of Mars' atmosphere, climate and
potential habitability in greater detail than ever before.
In addition, NASA also will fund a U.S. scientist to participate in a
proposed European Mars mission as well as fund instrument technology
studies that could lead to further contributions to future Mars
missions.
"These mission selections represent unprecedented future research that
will lead to further advancing our knowledge and understanding of the
Red Planet's climate, and atmospheric composition," said Mary Cleave,
associate administrator for NASA's Science Mission Directorate, NASA
Headquarters, Washington.
Each Mars mission proposal will receive initial funding of
approximately $2 million to conduct a nine-month implementation
feasibility study. Following these detailed mission concept studies,
NASA intends to select one of the two proposals by late 2007 for full
development as a Mars Scout mission. The mission developed for flight
would have a launch opportunity in 2011 and cost no more than $475
million.
The selected Mars mission proposals are:
* Mars Atmosphere and Volatile Evolution mission, or MAVEN: The
mission would provide first-of-its-kind measurements and address key
questions about Mars climate and habitability and improve
understanding of dynamic processes in the upper Martian atmosphere
and ionosphere. The principal investigator is Bruce Jakosky,
University of Colorado, Boulder. NASA's Goddard Space Flight Center,
Greenbelt, Md., will provide project management.
* The Great Escape mission: The mission would directly determine the
basic processes in Martian atmospheric evolution by measuring the
structure and dynamics of the upper atmosphere. In addition,
potentially biogenic atmospheric constituents such as methane would
be measured. The principal investigator is Alan Stern, Southwest
Research Institute, Boulder, Colorado. Southwest Research Institute,
San Antonio, will provide project management.
NASA has selected Alian Wang of Washington University, St. Louis, to
participate as a member of the science team for the European Space
Agency's ExoMars mission. Wang will receive approximately $800,000 to
study the chemistry, mineralogy and astrobiology of Mars using
instrumentation on the ExoMars mission, scheduled for launch in 2013.
NASA also has selected two proposals for technology development
studies that may lead to further NASA contributions to ExoMars or
other Mars missions. The two technology development studies, funded
for a total of $1.5 million, are:
* Urey Mars Organic and Oxidant Detector: The Urey instrument would
investigate organics and oxidant materials on Mars using three
complementary detection systems. The principal investigator is
Jeffrey Bada, University of California at San Diego.
* Mars Organic Molecule Analyzer, or MOMA: The instrument would
investigate organic molecular signatures and the environment in which
they exist using a mass spectrometer and gas chromatograph. The
principal investigator is Luann Becker, University of California at
Santa Barbara.
These selections were judged to have the best science value among 26
proposals submitted to NASA in August 2006 in response to an open
announcement of opportunity.
NASA's Mars Exploration Program seeks to characterize and understand
Mars as a dynamic system, including its present and past environment,
climate cycles, geology and biological potential. The Mars
Exploration Program Office is managed by NASA's Jet Propulsion
Laboratory, Pasadena, Calif., for the Mars Exploration Program,
Science Mission Directorate, Washington.
