Every opposition has some significance because Mars is visible from Earth all night, high and fully lit, but the ones of special interest happen when Mars is near perihelion, because this is when Mars is also nearest to Earth. One perihelic opposition is followed by another either 15 or 17 years later. In fact every opposition is followed by a ...
Roving Mars is a 2006 American IMAX documentary film about the development, launch, and operation of the Mars Exploration Rovers, Spirit and Opportunity. [3] The film uses few actual photographs from Mars, opting to use computer generated animation based on the photographs and data from the rovers and other Mars probes. [ 4 ]
The animated science fiction film, one of several in the Starship Troopers franchise, features a demoted general stationed on Mars who has to train poorly-performing troopers. The military has to confront alien bugs that decide to target Mars. [24] Stranded (Spanish: Náufragos) 2001: A human mission to Mars crash-lands on the planet, stranding ...
Substituting the mass of Mars for M and the Martian sidereal day for T and solving for the semimajor axis yields a synchronous orbit radius of 20,428 km (12,693 mi) above the surface of the Mars equator. [3] [4] [5] Subtracting Mars's radius gives an orbital altitude of 17,032 km (10,583 mi). Two stable longitudes exist - 17.92°W and 167.83°E.

In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
Phobos orbits so fast (with a period of just under one third of a sol) that it rises in the west and sets in the east, and does so twice per sol; Deimos on the other hand rises in the east and sets in the west, but orbits only a few hours slower than a Martian sol, so it spends about two and a half sols above the horizon at a time.
Mars comes into opposition from Earth every 2.1 years. The planets come into opposition near Mars's perihelion in 2003, 2018 and 2035, with the 2020 and 2033 events being particularly close to perihelic opposition. [192] [193] [194] Mars seen through a 16-inch amateur telescope, at 2020 opposition
