Instruments
The Phobos-Soil (Phobos-Grunt) payload contains several optical cameras that will obtain panoramic and stereo images of the surface near the landing site. One of the cameras, TSNN, is designed for landing and navigation support. A set of instruments will study the properties of the near-Mars plasma environment and its interaction with the solar wind. The internal structure of Phobos will be studied with the use of seismic methods and the long wave radar.
In addition to remote sensing instruments, the mission is equipped with a comprehensive suite of instruments to study the Phobos regolith in situ.
The lander will acquire samples of the regolith, including pebbles approximately 1 cubic centimeter in size, amounting to a total volume of about 100 cubic centimetres. The preliminary landing site has been chosen based on high resolution image data from Mars Express. It spans 7°N to 21°N and 214°W to 233°W.
Sample collection and in situ studies of regolith are limited by the reach of the manipulator device, which extends about 1 m from the spacecraft, although it has the capability to sample several points of the landing site.
The mission will also carry two life sciences experiments to test survivability of microbes in space.
