Phobos 2

The mission to Phobos was announced on 14 November 1984. ==Mission profile==

Phobos 2 started to develop problems during the interplanetary flight phase of the mission. Phobos 2 successfully carried out three preliminary encounters with Phobos by using its Videospectrometric Camera, the Combined Radiometer and Photometer for Mars and the Imaging Spectrometer for Mars. ==Spacecraft design==

Instruments The Phobos 2 infrared spectrometer (ISM) obtained 45000 spectra in the near infrared (from ) in the equatorial areas of Mars, with a spatial resolution ranging from , and 400 spectra of Phobos at 700 m resolution. These observations made it possible to generate the first mineralogical maps of the planet and its satellite, and to study the atmosphere of Mars. ISM was developed at IAS and DESPA (Paris Observatory) with support from CNES. List of instruments: • "VSK" TV imaging system • PROP-F "hopping" lander. • ARS-FP automatic X-ray fluorescence spectrometer • ferroprobe magnetometer • Kappameter magnetic permeability / susceptibility sensor • gravimeter • temperature sensors • BISIN conductometer / tiltmeter • mechanical sensors (penetrometer, UIU accelerometer, sensors on hopping mechanism) • "DAS" (long-lived autonomous station) lander • TV camera • ALPHA-X Alpha-Proton-X-Ray Spectrometer • LIBRATION Sun sensor (also known as STENOPEE) • Seismometer • RAZREZ anchor penetrometer • Celestial mechanics experiment • "ISM" thermal infrared spectrometer/radiometer – resolution • near-infrared imaging spectrometer • thermal imaging camera; magnetometers • gamma-ray spectrometers • X-ray telescope • radiation detectors • radar and laser altimeters • Lima-D laser experiment – designed to vaporize material from the Phobos surface for chemical analysis by a mass spectrometer • Automatic Space Plasma Experiment with Rotating Analyzer (ASPERA), an electron spectrometer and ion mass analyzer from the Swedish Institute of Space Physics. ==Results==

The craft took 37 photos of Phobos imaging the majority (80%) of the moon. ==Legacy==

The Phobos design was used again for the long delayed Mars 96 mission which ended in failure when the launch vehicle's fourth stage misfired. In addition, the Fobos-Grunt mission, also designed to explore Phobos, failed in 2011. There has yet to be a completely successful probe to Phobos. ==References==
