* Orbital eccentricity, in astrodynamics, calculated from orbital state vectors as an absolute value of eccentricity vector or using other methods based on orbital energy and angular momentum

* Orbital simulations by Varadi, Ghil and Runnegar ( 2003 ) provide another, slightly different series for Earth orbit eccentricity, and also a series for orbital inclination.

e is Orbital eccentricity | eccentricity.

Orbital eccentricity | Eccentricity is indicated by yellow bars illustrating the object's maximum and minimum distances from Jupiter.

Solar radiation pressure will in general perturb the eccentricity ( i. e. the eccentricity vector ), see Orbital perturbation analysis ( spacecraft ).

Orbital mechanics require that the length of the seasons be proportional to the swept areas of the seasonal quadrants, so when the eccentricity is extreme, the seasons on the far side of the orbit can last substantially longer.

The Orbital eccentricity | eccentricity of the orbits is represented by segments ( extending from the perihelion to the aphelion ) with the inclination represented on Y axis.

The M25 motorway, or London Orbital motorway is a motorway that ( almost ) encircles Greater London, England, in the United Kingdom.

In the ZOE series, the BAHRAM military corporation is the primary developer of Orbital Frame technology and the general antagonist.

The most intimidating Orbital Frame, Anubis, is his frame of choice in his mission to eliminate the universe.

Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft.

Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary transfers, and is used by mission planners to predict the results of propulsive maneuvers.

Released in 1987 ; Roger, with his newfound status of Hero, is transferred to the Xenon Orbital Station 4 and promoted to head ( and only ) janitor.

The applied tools of the mathematics disciplines of Celestial mechanics or its subfield Orbital mechanics ( both predict orbital paths and positions ) about a center of gravity are used to generate an ephemeris ( plural: ephemerides ; from the Greek word ephemeros = daily ) which is a table of values that gives the positions of astronomical objects in the sky at a given time or times, or a formula to calculate such given the proper time offset from the epoch.

Orbital speed ( how fast the satellite is moving through space ) is calculated by multiplying the angular speed by the orbital radius:

Orbital angular momentum multiplexing is a relatively new and experimental technique for multiplexing multiple channels of signals carried using electromagnetic radiation over a single path.

According to a 2009 report, RKK Energia is considering methods to remove from the station some modules of the Russian Orbital Segment when the end of mission is reached for the ISS and use them as a basis for a new station, known as the Orbital Piloted Assembly and Experiment Complex.

Orbital expansion is attempted to revitalize the world.

The next raid takes place on the Orbital Vavatch, a massive artificial " ringworld " 14 million kilometres in diameter, which the Culture is about to destroy to prevent the Idirans taking it over.

The crew lands on an abandoned Megaliner cruising the Vavatch ocean, hoping to salvage its powerful laser weapons before the Orbital is destroyed, but one of the crew is killed soon after landing because he missed the briefing warning them that their antigravity devices would not work there, and more die when the ship crashes into a massive ice wall, which Kraiklyn had mistaken for a cloud bank, although Horza later discovers that Kraiklyn and several others managed to escape.

Jernau Morat Gurgeh, a famously skilful player of board games and other similar contests, lives on Chiark Orbital, and is bored with his successful life.

Quilan is then sent to Masaq Orbital ostensibly to persuade Mahrai Ziller to return to his native Chel.

In Iain M. Banks ' fictional Culture universe, an Orbital ( sometimes also simply called an O or a small ring ) is a purpose-built space habitat forming a massive ring ( though much smaller than a ringworld ) rotating to simulate gravity.

An Orbital is similar to a ringworld but is much smaller and does not enclose its primary star within itself, instead orbiting the star in a more conventional manner, making it much more intrinsically stable than a ringworld.

The low-pressure direct gasoline injection developed by R Sarich was tested by Ford in an automobile size 2-stroke engine, and in 2012, Orbital won a contract by the Australia government for a two-stroke, direct injection engine for airborne drones.

The first flight of Columbia ( STS-1 ) was commanded by John Young, a Gemini and Apollo veteran who was the ninth person to walk on the Moon in 1972, and piloted by Robert Crippen, a rookie astronaut originally selected to fly on the military's Manned Orbital Laboratory ( MOL ) spacecraft, but transferred to NASA after its cancellation, and served as a support crew member for the Skylab and Apollo-Soyuz missions.

Orbital complications were categorized by Chandler et al.

DoD wanted its own manned facility, however, and in December it announced Manned Orbital Laboratory ( MOL ), a small space station primarily intended for photo reconnaissance using large telescopes directed by a two-man crew.

Nevertheless, in late July it was announced that the Orbital Workshop would be launched as a part of Apollo mission AS-209, originally one of the Earth-orbit CSM test launches, followed by two Saturn I / CSM crew launches, AAP-1 and AAP-2.

By the end of 2012 cargo supply to the International Space Station will be flown by privately owned commercial craft under NASA's Commercial Resupply Services by SpaceX's successfully tested the partially reusable Dragon spacecraft, and Orbital Sciences ' Cygnus spacecraft ( also slated for testing in 2012 ).

As the fugitives warp away from Vavatch, they see the Orbital destroyed by the Culture warships.

These also serve to contain the atmosphere in those areas where the Orbital may not yet be complete, with those gaps in the plate ring being bridged only by forcefields.

Some plates mimic natural environments very closely, others are wild exaggerations possible only by advanced matter forming and intricate ( but usually hidden ) machinery -- such as a gigantic river circumnavigating the whole Orbital, which in some regions travels on immense, kilometre-high bridge-or mountain-range-like constructions, and in other regions might act as an immense ' waterslide ' for a floating event stadium.

By tilting the axis of the Orbital relative to its orbit around a star a convenient day-night cycle can be experienced by the inhabitants.
