The National Aeronautics and Space Administration (NASA) is soliciting the submission of multiinstitutional team-based proposals for research as participating members of the Solar System Exploration Research Virtual Institute (SSERVI), hereafter referred to as "the Institute."
Some 135 years after its discovery, Mars' largest moon Phobos is seen in fantastic detail - and in 3D - in an image taken by ESA's Mars Express spacecraft as it passed just 100 km by.
This picture of Phobos near the limb of Mars was captured in 2010 by Mars Express currently orbiting Mars. Phobos is a heavily cratered and barren moon, with its largest crater located on the far side.

Phobos is the larger and closer of the two natural satellites of Mars. Despite decades of Martian exploration, we still know very little about Phobos. Many fundamental properties of this small potato-shaped body stay vague, for example, its gravitational field.
