The Deep Space 2 (DS2) project is a New Millenium mission
consisting of two probes which will penetrate
the surface of Mars near the south polar layered terrain and send back data on the
sub-surface properties. Also named the Mars Microprobe Project, the probe mission has as
scientific objectives to: 1) test for the presence of water ice below the surface, and if
ice exists, attempt to resolve the mineral phases in which the ice is stored; 2) determine
the thermal and physical properties and temperature gradient of the subsurface material;
3) measure the atmospheric pressure and temperature. Data may also be obtained on the
atmospheric density profile and near-surface soil stratification using deceleration
measurements during atmospheric entry and landing. The mission will also serve as a
technology test for many of the components of the probes and a demonstration of passive
atmospheric entry and survivable hard impact.
