  2. Orbital decay - Wikipedia

    en.wikipedia.org/wiki/Orbital_decay

    Orbital decay is a gradual decrease of the distance between two orbiting bodies at their closest approach (the periapsis) over many orbital periods. These orbiting bodies can be a planet and its satellite , a star and any object orbiting it, or components of any binary system .

  3. Video game modding - Wikipedia

    en.wikipedia.org/wiki/Video_game_modding

    Mod packs are groups of mods put into one package for download, often with an auto-installer. A mod pack's purpose is to make it easier for the player to install and manage multiple mods. [73] Mod packs may be created with the purpose of making the original game more accessible to new players or to make the game harder for veterans to enjoy.

  4. Trainer (games) - Wikipedia

    en.wikipedia.org/wiki/Trainer_(games)

    Game trainers are programs made to modify memory of a computer game thereby modifying its behavior using addresses and values, in order to allow cheating. It can "freeze" a memory address disallowing the game from lowering or changing the information stored at that memory address (e.g. health meter, ammo counter, etc.) or manipulate the data at the memory addresses specified to suit the needs ...

  5. 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 ...

  6. Zero-propellant maneuver - Wikipedia

    en.wikipedia.org/wiki/Zero-propellant_maneuver

    Spacecraft experience orbital decay due to drag. To maintain their orbit, thrusters are used to reboost the spacecraft to a higher altitude. Because on board propellant capacity is limited, the spacecraft can only perform a limited number of momentum desaturations or reboosts.

  7. Reboost - Wikipedia

    en.wikipedia.org/wiki/Reboost

    A reboost is the process of boosting the altitude of an artificial satellite in Low Earth Orbit [1] [2] [3] in order to delay its atmospheric re-entry due to orbital decay. [ 3 ] See also

  8. Adaptive tile refresh - Wikipedia

    en.wikipedia.org/wiki/Adaptive_tile_refresh

    Adaptive tile refresh is a computer graphics technique for side-scrolling video games.It was most famously used by id Software's John Carmack in games such as Commander Keen to compensate for the poor graphics performance of PCs in the early 1990s.

  9. Hulse–Taylor pulsar - Wikipedia

    en.wikipedia.org/wiki/Hulse–Taylor_pulsar

    [2] [10] [11] [12] The ratio of observed to predicted rate of orbital decay is calculated to be 0.997 ± 0.002. [12] The total power of the gravitational waves emitted by this system presently is calculated to be 7.35 × 10 24 watts. For comparison, this is 1.9% of the power radiated in light by the Sun.
