In an orbiting spacecraft, zero gravity is experienced as weightlessness. 7, record 1, English, - weightlessness
Record number: 1, Textual support number: 1 OBS
A condition of apparent absence of an acceleration field. This may be experienced during unopposed acceleration at that rate imposed by the gravitational field (e.g. free fall in a vacuum or within a closed vessel), when the gravitational force is countered by an equal and opposite force (as in orbital flight) or during flight at escape velocity. Partial simulation is commonly conducted by immersion in a liquid of specific gravity close to that of the body. 6, record 1, English, - weightlessness

L'impesanteur, dans le domaine de l'astronautique comme dans tout autre, est l'état d'un corps tel que l'ensemble des forces gravitationnelles et inertielles auxquelles il est soumis possède une résultante et un moment résultant nuls. L'impesanteur [...] est donc le phénomène ressenti en l'absence de pesanteur. L'impesanteur n'est donc pas provoquée par l'éloignement de la Terre ou de tout autre corps céleste attractif : l'accélération due à la gravité à une hauteur de 100 km par exemple n'est que de 4 % moindre qu'à la surface de la Terre. En réalité, l'impesanteur est ressentie lorsque l'accélération subie égale la gravité, ce qui recouvre aussi le cas où le champ de gravité serait nul, ce qui n'arrive pas puisque l'influence de la gravité est partout dans l'Univers. 8, record 1, French, - impesanteur

Se define ingravidez como el estado en el que un cuerpo tiene peso nulo. El motivo por el cual el peso se hace nulo es que la fuerza gravitatoria sea contrarrestada por la fuerza centrífuga (en un sistema de referencia solidario con el cuerpo) o por alguna fuerza de igual intensidad que el peso, pero que actúe en la dirección opuesta. 1, record 1, Spanish, - ingravidez

For launches into Earth orbit the main constraints are the desired orbit, the point of injection into that orbit, and the possibility of a collision with other orbiting spacecraft or orbital debris. For launches to interplanetary trajectories, the time of launch is constrained by the relative positions of the planets, at the time of both launch and encounter(i. e. the spacecraft must be aimed at a point in space that the planet will have reached by the time of encounter). A spacecraft launched outside the launch window would require more propellant and/or more time to reach its target. 2, record 6, English, - launch%20window

The angular momentum of a tumbling orbiting satellite is changed to reduce the spinning of the spacecraft such that the spacecraft can operate in an essentially stabilized condition. The change in spin rate is accomplished by the development of a magnetic torque by commutation of magnetic air coils in response to Earth sensor signals controlled by spacecraft logic. The coils are disposed to produce magnetic dipoles transverse to the satellite spin axis such that by interacting with the Earth's magnetic field a torque is developed in a direction opposite the spin vector. The logic selects the proper magnetic dipole based upon data from sensors detecting the presence of the Earth for the development of the desired magnetic torque. 5, record 8, English, - magnetotorquer

Even in a gravity gradient attitude, accelerations caused by crew movements, equipment operations, and occasional thruster firings can disrupt the quiescent low-gravity environment and may affect microgravity science experiments. Accelerations at particular frequencies may interrupt one type of experiment but have no effect on others. These accelerations are measured at fractions of Earth’s gravity; for instance, 10~ g is equal to 1/100,000 of the gravity on Earth. 3, record 13, English, - microgravity%20environment

Un environnement en microgravité offre aux scientifiques une occasion unique de contrôler les phénomènes liés à la gravité. De plus, en microgravité, le traitement sans contenant peut être pratiqué sur de plus gros échantillons, car les force acoustiques et électromagnétiques utilisées pour manipuler ne sont pas dominées par la gravité. 2, record 13, French, - environnement%20en%20microgravit%C3%A9

Returning to the Earth involves the problem of decreasing the spacecraft's great speed. To do this, an orbiting spacecraft uses small rockets to redirect its flight path into the upper atmosphere. This action is called de-orbit. A spacecraft returning to the Earth from the moon or from another planet also aims its path to skim the upper atmosphere. Air resistance then provides the rest of the necessary deceleration(speed reduction). 1, record 14, English, - air%20resistance

The scientific objective of POLO [Polar Orbiting Lunar Observatory] is to make a complete global survey of the Moon's physical and chemical properties using two spacecraft, one in low-altitude polar orbit about the Moon, the other in high-altitude lunar orbit. The basic payload of the Orbiter would contain X-and gamma-ray spectrometers, a multispectral stereo imaging system, a reflectance spectrometer, an altimeter, a magnetometer and an alpha-particle detector. 1, record 15, English, - reflectance%20spectrometer
