Artist's rendering of NASA's 2001 Mars Odyssey orbiting Mars. The following table is a list of Mars orbiters, consisting of space probes which were launched from Earth and are currently orbiting Mars. As of August 2023, there have been 18 spacecraft missions operating in Mars' orbit, 7 of which are currently active.
The satellites of Mars include : Non functional but (probably) orbiting: Viking 1 & 2 orbiter; Mariner 9; Mars Global Surveyor; Mars 2, 3, 5; Phobos 2;
Mars 2: Mars: Failure: Orbiter and lander, created the first human artifact on Mars Soviet Union: Mars 3: Mars: Success: Orbiter and lander, first successful landing on Mars US: Mariner 9: Mars: Success: Orbiter, first pictures of Mars' moons (Phobos and Deimos) taken Canada: ISIS 2: Earth: Success Japan: Shinsei: Earth: Partial success: First ...
Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
The Next Mars Orbiter (NeMO, earlier known as the Mars 2022 orbiter) is a proposed NASA Mars communications satellite with high-resolution imaging payload and two solar-electric ion thrusters. [ 2 ] [ 3 ]
Animation of InSight 's trajectory InSight · Earth · Mars Mars launch windows and distance from Earth In the context of spaceflight, launch period is the collection of days, and launch window is the time period on a given day, during which a particular rocket must be launched in order to reach its intended target.
A satellite in areosynchronous orbit does not necessarily maintain a fixed position in the sky as seen by an observer on the surface of Mars; however, such a satellite will return to the same apparent position every Martian day. The orbital altitude required to maintain an areosynchronous orbit is approximately 17,000 kilometres (11,000 mi).
