With this the driller can create 4-D images (three dimensions plus time) of oil reservoirs via a seismic vibration sensor attached to the end of a fiber-optic cable pushed down into a well.

Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet's surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars' rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet's internal temperature.
