USERS (Unmanned Space Experiment Recovery System) was a Japanese microgravity experimental satellite. After 8.5 months in orbit, a reentry vehicle was to be returned to earth with the materials manufacturered in space. DRTS (Data Relay & Tracking Satellite) is an inter-satellite communications experiment satellite to relay data between the target spacecraft (low earth orbit satellites, space stations, etc.) and ground stations.
Geostationary Transfer OrbitEchoStar VIII was an American geostationary communications satellite which is operated by EchoStar. It is positioned in geostationary orbit at a longitude of 77° West, from where it is used to provide high-definition television direct broadcasting services to the Contiguous United States.
Geostationary Transfer OrbitEutelsat 8 West C, known as Hot Bird 6 prior to 2012 and Hot Bird 13A from 2012 to 2013, is a French communications satellite. Operated by Eutelsat, it provides direct to home broadcasting services from geostationary orbit.
Geostationary Transfer OrbitThis was the second launch of the Arkon-1 electro-optical reconnaissance. The 17S40 Blok DM5 upper stage and satellite were placed by the Proton into a parking orbit. The DM then made two burns to place the satellite in its 1500 x 1836 km x 64.4 deg operational orbit.
Low Earth OrbitThe CONTOUR (Comet Nucleus Tour) probe, built and operated by the Johns Hopkins University's Applied Physics Laboratory (APL), began its five year mission to explore three comets, using repeated encounters with the earth to modify its orbit in order to reach each target.
