Mars 2007 Missions and beyond
Launch Period: 3 August 2007
Planned for launch in 2007 is a Scout mission,
a lander designed to study the surface and near-surface environment
of a landing site in the high-northern latitudes of Mars.
The spacecraft comprises an octagonal base supported on three landing legs.
Two octagonal solar panel wings extend from the base to provide power. The
science experiments and a robotic arm are mounted on the base. The
experiments are: the Microscopy, Electrochemistry, and Conductivity Analyzer
(MECA), the Robotic Arm Camera (RAC), the Surface Stereo Imager (SSI), the
Thermal and Evolved Gas Analyzer (TEGA), the Mars Descent Imager (MARDI),
and the meteorological station (MET).
There is a 22 day launch window for Phoenix opening on 3 August 2007 at 0935
UT (5:35 a.m. EDT). Launch is on a Delta II 7925 from Cape Canaveral Air
Force Station. Cruise to Mars will take approximately 10 months, with
landing on Mars in mid-May of 2008. All instruments will be deployed in the
first two days after landing. See the
9 July 2007 NASA press release
for more information.
Phoenix was selected for the 2007 launch from four proposals for future Scout missions to Mars.
For further information on the selection, see the
4 August 2003 NASA press release.

sensing orbiter and four small "Netlanders" but these have been
Launch Period: Late 2009
Mars Science Laboratory
A long duration rover (mobile scientific laboratory) equipped to perform many
scientific studies of Mars, to be chosen competitively, is planned for a
late 2009 launch. The primary scientific objectives of the mission will be
to assess the biological potential of at least one target area, characterize
the local geology and geochemistry, investigate planetary processes relevant
to habitability, including the role of water, and to characterize the broad
spectrum of surface radiation. The mission is planned to last at least one
martian year (687 days). The landing site has not been chosen, but will
be selected based on an assessment of its capacity to sustain life.
A synthetic aperture radar satellite developed with Italy
is also being considered for the 2009 launch window to Mars.

Future Mars Opportunities
In the second decade, NASA plans additional science orbiters,
rovers and landers, and the first mission to return the most
promising Martian samples to Earth. Current plans call for a
Mars Scout mission (to be determined) to launch in 2011 and the
first sample return mission to be launched no later than 2020.
A CNES Orbiter will collect the
samples from Mars Ascent Vehicles and bring them back to Earth.
Technology development for advanced capabilities
such as miniaturized surface science instruments and deep drilling
to several hundred feet will also be carried out in this period.
