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.
