Orbital maneuver – In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. Orbital mechanics – or astrodynamics , is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft .
The College Board advises that students choosing AP English Language and Composition be interested in studying and writing various kinds of analytic or persuasive essays on non-fiction topics, while students choosing AP English Literature and Composition be interested in studying literature of various periods and mediums (fiction, poetry, drama ...
An animation showing a low eccentricity orbit (near-circle, in red), and a high eccentricity orbit (ellipse, in purple). In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object [1] such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such ...
Also angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance. A scalar measure of rotation rate. It refers to the angular displacement per unit time (e.g. in rotation) or the rate of change of the phase of a sinusoidal waveform (e.g. in oscillations and waves), or as the rate of change of the ...
Russian definition: <5,000 kg (11,000 lb) A small-lift launch vehicle is a rocket orbital launch vehicle that is capable of lifting 2,000 kilograms (4,400 lb) or less (by NASA classification) or under 5,000 kilograms (11,000 lb) (by Roscosmos classification) [ 1 ] of payload into low Earth orbit (LEO).

This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun").
The first US medium-lift vehicle was a purpose-built orbital launch vehicle, the Saturn I. Saturn I first launched in 1961, and the Saturn family would eventually grow into the heavy-lift Saturn IB and the super-heavy lift Saturn V. [4] ICBM-derived launch vehicles for the US include the Atlas, Titan, and Delta families.
