The American Space Agency Nasa... is putting several million dollars into the project under its advanced concepts programme. At the heart of a space elevator would be a cable reaching up as far as 100, 000km from the surface of the Earth. The earthbound end would be tethered to a base station, probably somewhere in the middle of the Pacific ocean. The other end would be attached to an orbiting object in space acting as a counterweight, the momentum of which would keep the cable taut and allow vehicles to climb up and down it. A space elevator would make rockets redundant by granting cheaper access to space. At about a third of the way along the cable-36, 000 km from Earth-objects take a day to complete a full orbit. If the cable's centre of gravity remained at this height, the cable would remain vertical, as satellites placed at this height are geostationary, effectively hovering over the same spot on the ground. To build a space elevator such a geostationary satellite would be placed into orbit carrying the coiled-up cable. One weighted end of the cable would then be dropped back towards Earth, while the other would be unreeled off into space. Mechanical lifters could then climb up the cable from the ground, ferrying up satellites, space probes and eventually tourists. The biggest technical obstacle is finding a material strong but light enough to make the cable; this is where the carbon nanotubes come in. These are microscopically thin tubes of carbon that are as strong as diamonds but flexible enough to turn into fibre. In theory, a nanotube ribbon about one metre wide and as thin as paper could support a space elevator.

La NIAC (Institut des Concepts Avancées de la NASA) a publié une étude fin 2002 sur tous les aspects d'un système d'ascenseur spatial, de la construction aux opérations. Premièrement, l'ascenseur serait constitué d'un câble d'une longueur de 91 000 km et d'un diamètre variant de 1 micron à 11.5 cm. Ce filin serait mis en orbite à l'aide d'une navette spatiale aidée de quelques propulseurs supplémentaires, qui, une fois en orbite géostationnaire, serviraient de contrepoids. Les forces centripètes repousseraient alors la partie haute du filin vers l'espace tandis que la partie basse serait attirée par la Terre, mettant le tout en tension. Ce premier lien serait capable d'envoyer plus d'une tonne en orbite. Il suffira ensuite d'utiliser ce premier câble pour en mettre en orbite de nouveaux. Ces filins seront constitués de nanotubes de carbone. Le plus gros défi technologique serait de construire 91 000 km de nanotubes car aujourd'hui la technologie ne permet d'en construire que quelques centimètres. Le ratio actuel nanotube/résine epoxy est de 60/40. Il faudra réussir à descendre à 98/2. Les principaux risques liés au transport par ascenseur seront dus aux météorites, aux ouragans ou aux attaques terroristes. Le filin pourra être réparé in-situ. Ce système ne nécessiterait pas de maîtriser la fusion nucléaire. De simples batteries et panneaux solaires suffiront à alimenter l'ascenseur. La plupart des technologies nécessaires existent déjà ou existeront dans le court terme. Les prévisions actuelles prévoient un budget de 7 à 10 milliards sur 15 ans.

  • Spacecraft
DEF

A device which makes use of a planet’s magnetic field to stabilise a satellite.

CONT

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.

The ROCSAT3/COSMIC(Constellation Observing System for Meteorology, Ionosphere and Climate) mission consists of a constellation of 6 low-earth orbiting satellites. In conducting the atmospheric limb sounding using the GPS radio occultation technique(which is the main objective of the mission), the satellite orbits are precisely determined at any given moment by GPS "high-low" satellite-to-satellite tracking. These precise orbit determination(POD) data contain useful information about the Earth's gravitational field and its time variations, for both geophysical and climate-related research.

Even today, a geostationary satellite, whose useful life has ended, must be abandoned in space. The experimental servicing satellite ESS applies robotics to resolve the problem of servicing a non-cooperative target in or near to a geostationary orbit, a region of space still out of reach to manned spaceflight. A three-month demonstration flight of ESS has been planned and all phases of its mission have been defined. These include the acquisition, inspection and servicing of an orbiting satellite through to parking it in a "graveyard" orbit. The project builds on the experience gained with the robotics technology experiment Rotex, flown on the D2 Mission.

STEP :Satellite Test of the Equivalence Principle. Worden and Everitt have proposed to carry out an improved version of Galileo's Leaning Tower of Pisa experiment, by placing masses of different composition inside a satellite orbiting the Earth to obtain a long duration of free fall. Very high positional sensitivity can be achieved by cooling the experiment to 1. 8 K and using SQUIDs to detect in current changes in magnetic pickup coils. The test masses of different materials and the position measuring equipment are placed inside the satellite and micro Newton thrusters are used to cancel the small accelerations of the satellite due to air drag, radiation pressure and the solar wind which could couple to masses.

Orbiting Astronomical Observatory(OAO), series of four orbiting observatories launched between 1966 and 1972 by the National Aeronautics and Space Administration(NASA) to provide astronomical data in the ultraviolet and X-ray wavelengths filtered out by the earth's atmosphere. Only two of the four launches were successful, however. OAO-2, launched in 1978, which carried two large telescopes in addition to a cluster of four ultraviolet telescopes, four photoelectric telescopes, and a number of spectrometers and other devices, weighed 4, 200 lb(1, 900 kg) and was the heaviest satellite orbited to that time. Working primarily with ultraviolet radiation, it was able to photograph very young stars. OAO-3, which was also called Copernicus, was launched in 1972. Carrying what was at that time the largest telescope ever orbited and three smaller X-ray telescopes, OAO-3 was primarily used in the study of ultraviolet radiation from interstellar gas and dust and from stars near the edges of the Milky Way.
