interplanetary orbit
11Orbit of the Moon — Not to be confused with Lunar orbit in the sense of a selenocentric orbit, that is, an orbit around the Moon The Moon completes its orbit around the Earth in approximately 27.3 days (a sidereal month). The Earth and Moon orbit about their… …
12Orbit equation — In astrodynamics an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time. Under standard assumptions, a body moving under the influence of a force, directed to a… …
13Interplanetary Magnetic Field — The Interplanetary Magnetic Field (IMF) is the term for the Sun’s magnetic field carried by the solar wind among the planets of the Solar System. [ heliospheric current sheet is a three dimensional form of a Parker spiral that results from the… …
14Orbit phasing — In astrodynamics orbit phasing is the adjustment of the time position of spacecraft along its orbit, usually described as adjusting the orbiting spacecraft s true anomaly. This is predominantly used in satellite positioning, especially if the… …
15Orbit Jet — The Orbit Jet was a fictional spaceship in the 1954 TV series Rocky Jones, Space Ranger. It strongly resembled a V 2 rocket in overall form, with a very prominent exhaust plume when flying, but had wings in addition to tailfins (even its radio… …
16Hohmann transfer orbit — In astronautics and aerospace engineering, the Hohmann transfer orbit is an orbital maneuver using two engine impulses which, under standard assumptions, move a spacecraft between two coplanar circular orbits. This maneuver was named after Walter …
17Geocentric orbit — Earth orbit redirects here. For the motion of the Earth around the Sun, see Earth s orbit. Earth orbiter redirects here. For the shuttle simulator, see Earth Orbiter 1. The following words may have more than one definition or other non Earth… …
18Single-stage-to-orbit — The VentureStar was a proposed SSTO spaceplane. A single stage to orbit (or SSTO) vehicle reaches orbit from the surface of a body without jettisoning hardware, expending only propellants and fluids. The term usually, but not exclusively, refers… …
19Gate orbit — Gate orbits are optimal circular departure orbits for transfer from one planet to another. At certain specific orbits around a cosmic body, the additional delta v required to go from orbital velocity to hyperbolic trajectory for an interplanetary …
20Geostationary orbit — Geostationary orbit.To an observer on the rotating Earth (fixed point on the Earth), the satellite appears stationary in the sky. A red satellite is also geostationary above its own point on Earth. Top Down View …
