orbital-transfer maneuver
1Orbital mechanics — A satellite orbiting the earth has a tangential velocity and an inward acceleration. Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other… …
2Orbital inclination change — is an orbital maneuver aimed at changing the inclination of an orbiting body s orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector… …
3Orbital Express — Orbital Express: ASTRO and NEXTSat Orbital Express was a space mission managed by the United States Defense Advanced Research Projects Agency (DARPA) and a team led by engineers at NASA s Marshall Space Flight Center (MSFC). The Orbital Express… …

5Orbital maneuver — In spaceflight, an orbital maneuver is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth for example those in orbits around the Sun an orbital maneuver is called a deep space maneuver (DSM).[not… …
6Orbital station-keeping — In astrodynamics orbital station keeping is a term used to describe the orbital maneuvers made by thruster burns that are needed to keep a spacecraft in a particular assigned orbit. For many Earth satellites the effects of the non Keplerian… …
7Transfer orbit stage — The Transfer Orbit Stage (TOS) was an upper stage rocket developed by Martin Marietta on a subcontract to Orbital Sciences Corporation during the late 1980s and early 1990s. Orbital Sciences was the prime contractor for NASA for TOS. TOS was… …
8Orbital module — The orbital module is a portion of spacecraft used only in orbit. These have developed from the Soviet Soyuz spacecraft. Contents 1 Soyuz orbit module 2 Shenzhou orbit module 3 Other orbit modules 4 See also …
9Hohmann 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 …
