  2. Mars cycler - Wikipedia

    en.wikipedia.org/wiki/Mars_cycler

    Earth orbits the Sun in one Earth year, Mars in 1.881. 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 ...

  3. Characteristic energy - Wikipedia

    en.wikipedia.org/wiki/Characteristic_energy

    After reducing the problem to the relative motion of the bodies in the plane, he defines the constant of the motion c 3 by the equation ẋ 2 + ẏ 2 = 2k 2 M/r + c 3, where M is the total mass of the two bodies and k 2 is Moulton's notation for the gravitational constant. He defines c 1, c 2, and c 4 to be other constants of the

  4. Cycler - Wikipedia

    en.wikipedia.org/wiki/Cycler

    A cycler encounters two or more bodies regularly by employing a free-return trajectory, this trajectory was analysed by Arthur Schwaniger in 1963 with a symmetrical orbit past the Moon and Earth. [1] Once the orbit is established, no propulsion is required to shuttle between the two, although some minor corrections may be necessary due to small ...

  5. Areosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/Areosynchronous_orbit

    [1] An areosynchronous orbit that is equatorial (in the same plane as the equator of Mars), circular, and prograde (rotating about Mars's axis in the same direction as the planet's surface) is known as an areostationary orbit (AEO). To an observer on the surface of Mars, the position of a satellite in AEO would appear to be fixed in a constant ...

  6. Longitude of the ascending node - Wikipedia

    en.wikipedia.org/wiki/Longitude_of_the_ascending...

    Denoted with the symbol Ω, it is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node (☊), as measured in a specified reference plane. [1] The ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image.

    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.

    The next two months are, according to astrology, a time to unwind. Between Jan. 28 and April 1, 2024, not a single planet will be in retrograde. That is the equivalent of astrological smooth sailing.

  9. Deimos (moon) - Wikipedia

    en.wikipedia.org/wiki/Deimos_(moon)

    Deimos (/ ˈ d aɪ m ə s /; systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]
