Once in Mars orbit, PADME would carry out 16 flybys of Phobos followed by 9 flybys of Deimos. [5] Flybys would take place at two-week intervals. Flyby altitudes at closest approach to Phobos and Deimos would be ~2 km. [5] Following completion of its primary mission, PADME could remain in high Mars orbit for long-term monitoring of the martian system and search for potential additional moonlets ...
Both sets of findings support an origin of Phobos from material ejected by an impact on Mars that reaccreted in Martian orbit, [40] similar to the prevailing theory for the origin of Earth's moon. The moons of Mars may have started with a huge collision with a protoplanet one third the mass of Mars that formed a ring around Mars.
Phobos was the primary object of study for the Phobos 1 spacecraft. Phobos 1 was an uncrewed Soviet space probe of the Phobos Program launched from the Baikonour launch facility on 7 July 1988. [1] Its intended mission was to explore Mars and its moons Phobos and Deimos. The mission failed on 2 September 1988 when a computer malfunction caused ...

Numerous attempts [3] [4] [5] have been made over the years to determine an absolute Martian chronology (timeline) by comparing estimated impact cratering rates for Mars to those on the Moon. If the rate of impact crater formation on Mars by crater size per unit area over geologic time (the production rate or flux) is known with precision, then ...
Hubble's sharpest view of Mars: Although the ACS “Fastie finger” intrudes, it achieved a spatial scale of 5 miles, or 8 kilometres per pixel at full resolution. The history of Mars observation is about the recorded history of observation of the planet Mars.
Limtoc is an impact crater on the surface of Mars's moon Phobos. [1] The crater, the diameter of which is 2 kilometers, is located within the larger and better-known Stickney crater. [ 1 ] Limtoc was officially named by the International Astronomical Union on 29 November 2006, after a character from Jonathan Swift ’s 1726 satirical novel ...
