  2. Orbiter (simulator) - Wikipedia

    en.wikipedia.org/wiki/Orbiter_(simulator)

    Orbiter was developed as a simulator, [14] with accurately modeled planetary motion, gravitation effects (including non-spherical gravity), free space, atmospheric flight and orbital decay. [15] [16] The position of the planets in the solar system is calculated by the VSOP87 solution, while the Earth-Moon system is simulated by the ELP2000 ...

  3. Orbit of Mars - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Mars

    Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...

  4. Orbit modeling - Wikipedia

    en.wikipedia.org/wiki/Orbit_modeling

    Orbit modeling is the process of creating mathematical models to simulate motion of a massive body as it moves in orbit around another massive body due to gravity.Other forces such as gravitational attraction from tertiary bodies, air resistance, solar pressure, or thrust from a propulsion system are typically modeled as secondary effects.

  6. Elon Musk's Tesla Roadster - Wikipedia

    en.wikipedia.org/wiki/Elon_Musk's_Tesla_Roadster

    The Roadster is in a heliocentric orbit that crosses the orbit of Mars and reaches a distance of 1.66 au from the Sun. [6] With an inclination of roughly 1 degree to the ecliptic plane, compared to Mars' 1.85° inclination, this trajectory by design cannot intercept Mars, so the car will neither fly by Mars nor enter an orbit around Mars. [40]

  7. Hohmann transfer orbit - Wikipedia

    en.wikipedia.org/wiki/Hohmann_transfer_orbit

    The diagram shows a Hohmann transfer orbit to bring a spacecraft from a lower circular orbit into a higher one. It is an elliptic orbit that is tangential both to the lower circular orbit the spacecraft is to leave (cyan, labeled 1 on diagram) and the higher circular orbit that it is to reach (red, labeled 3 on diagram).

  9. Mars general circulation model - Wikipedia

    en.wikipedia.org/wiki/Mars_General_Circulation_Model

    Mars climate simulation models date as far back as the Viking missions to Mars. Most Mars climate simulation models were written by individual researchers that were never reused or open-sourced. By the 1990s the need for a unified model codebase came into being, due to the general impact of the internet on climate modelling and research. This ...
