initial orbit
11Air launch to orbit — is the method of launching booster rockets at altitude from a horizontal takeoff turbojet aircraft, either subsonic or supersonic. This method, when employed for orbital payload insertion, presents significant advantages over conventional… …
12Single-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… …
13Geostationary 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 …
14Parking orbit — A parking orbit is a temporary orbit used during the launch of a satellite or other space probe. A launch vehicle boosts into the parking orbit, then coasts for a while, then fires again to enter the final desired trajectory. The alternative to a …
15Earth's orbit — In astronomy, The Earth s Orbit involves the Earth orbiting the Sun at an average distance of about 150 million kilometers every 365.2564 mean solar days (1 sidereal year). From Earth, this gives an apparent movement of the Sun with respect to… …
16Muscles of orbit — Muscle Innervation Primary function Secondary function Tertiary function Levator palpebrae superioris Oculomotor nerve Elevation of the superior (upper) eyelid . . Superior rectus Oculomotor nerve Elevation Intorsion Adduction Inferior rectus… …

18Bi-elliptic transfer — In astronautics and aerospace engineering, the bi elliptic transfer is an orbital maneuver that moves a spacecraft from one orbit to another and may, in certain situations, require less delta v than a Hohmann transfer.The bi elliptic transfer… …
19Venus Express — Infobox Spacecraft Name = Venus Express Caption = Venus Express in Venus orbit Organization = ESA Major Contractors = EADS Astrium, Toulouse, France, leading a team of 25 subcontractors from 14 European countries. Mission Type = Orbiter Satellite …
20Aerobraking — is a spaceflight maneuver that reduces the high point of an elliptical orbit (apoapsis) by flying the vehicle through the atmosphere at the low point of the orbit (periapsis), using drag to slow the spacecraft. Aerobraking saves fuel, compared to …
