  2. Mars cycler - Wikipedia

    en.wikipedia.org/wiki/Mars_cycler

    Neither orbit is perfectly circular; Earth has an orbital eccentricity of 0.0168, and Mars of 0.0934. The two orbits are not quite coplanar either, as the orbit of Mars is inclined by 1.85 degrees to that of Earth. The effect of the gravity of Mars on the cycler orbits is almost negligible, but that of the far more massive Earth needs to be ...

  3. Interplanetary spaceflight - Wikipedia

    en.wikipedia.org/wiki/Interplanetary_spaceflight

    It is possible to put stations or spacecraft on orbits that cycle between different planets, for example a Mars cycler would synchronously cycle between Mars and Earth, with very little propellant usage to maintain the trajectory. Cyclers are conceptually a good idea, because massive radiation shields, life support and other equipment only need ...

    The orbiter reached Mars orbit on September 24, 2014. Through this mission, ISRO became the first space agency to succeed in its first attempt at a Mars orbiter. The mission is the first successful Asian interplanetary mission. [6] Ten days after ISRO's launch, NASA launched their seventh Mars orbiter MAVEN to study the Martian atmosphere.

  5. Areosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/Areosynchronous_orbit

    The areosynchronous orbits (ASO) are the synchronous orbits for artificial satellites around the planet Mars. They are the martian equivalent of the geosynchronous orbits (GSO) on the Earth . The prefix areo- derives from Ares , the ancient Greek god of war and counterpart to the Roman god Mars , with whom the planet was identified.

  6. Areostationary orbit - Wikipedia

    en.wikipedia.org/wiki/Areostationary_orbit

    Several factors make placing a spacecraft into an areostationary orbit more difficult than a geostationary orbit. Since the areostationary orbit lies between Mars's two natural satellites, Phobos (semi-major axis: 9,376 km) and Deimos (semi-major axis: 23,463 km), any satellites in the orbit will suffer increased orbital station keeping costs due to unwanted orbital resonance effects.
