101Apollo 15, Return to Earth — After the Apollo 15 Lunar Module Falcon lifted from the lunar surface it rendezvoused and docked with the Command/Service Module Endeavour . After transferring across the lunar samples and other equipment, Falcon was jettisoned. It would fire its …
102Kepler orbit — Gravitational attraction is the force that makes the Solar system stick together with the planets orbiting the Sun and the Moon orbiting the Earth. Isaac Newton formulated the physical law for this gravitational attraction which explained Kepler… …
103Hohmann 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 …
104Medium Earth Orbit — (MEO), sometimes called Intermediate Circular Orbit (ICO), is the region of space around the Earth above low Earth orbit (convert|2000|km|mi|0) and below geostationary orbit (convert|35786|km|mi|0). [ [http://e words.us/w/MEO.html MEO… …
105Low Earth Orbit — Ein Satellitenorbit ist die Umlaufbahn eines Satelliten um die Erde. Dieser Artikel befasst sich mit der Flughöhe. Zur genauen Beschreibung der Flugbahn bedarf es weiterer Kenngrößen, die die Artikel Bahnelemente und Satellitenbahnelemente… …

107Graveyard orbit — A graveyard orbit, also called a supersynchronous orbit, junk orbit or disposal orbit, is an orbit significantly above synchronous orbit, where spacecraft are intentionally placed at the end of their operational life. It is a measure performed in …
108Halo orbit — A halo orbit is a periodic, three dimensional orbit near the L1, L2, or L3 Lagrange points in the three body problem of orbital mechanics. A spacecraft in a halo orbit does not technically orbit the Lagrange point itself (which is just an… …
109Osculating orbit — In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space (at a given moment of time) is the gravitational Kepler orbit (i.e. ellipse or other conic) that it would have about its central body (corresponding to… …
110Geostationary transfer orbit — A Geosynchronous Transfer Orbit or Geostationary Transfer Orbit (GTO) is a Hohmann transfer orbit around the Earth between a low Earth orbit (LEO) and a geosynchronous orbit (GEO). It is an ellipse where the perigee is a point on a LEO and the… …
