Mars 2007 Missions and beyond

Mars 2007

Launch: 4 August 2007

Phoenix Lander

Phoenix, is 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).

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.

The CNES (French Space Agency) had planned to launch a remote sensing orbiter and four small "Netlanders" but these have been postponed indefinitely.

Mars 2011

Launch Period: Fall 2011

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 fall 2011 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.

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.
