  • Week provided more details of the Kopernikus 3 satellite launch profile which uses three burns of the Delta second stage This new Delta launch profile is more complex than for any other geostationary launch vehicle for instance the Ariane third stage burns only once and the Atlas Centaur makes two Centaur burns In the new Delta profile the Delta enters a standard low orbit on its first burn Two further burns then raise the apogee and perigee respectively to over 1000 km only at this point does the third stage spacecraft combination separate The third stage then fires to place the spacecraft in a geostationary transfer orbit this orbit has a high perigee but is otherwise normal The payload apogee engine can then be burned to achieve geostationary orbit This profile was used for the first time in August for the Satcom C4 launch and Kopernikus 3 was its second use By Oct 16 the three main apogee engine burns were complete and Kopernikus 3 was approaching its target longitude of 33 degrees East Erratum DFS 3 Kopernikus was built by Deutsche Aerospace not Aerospatiale as I said in the last report The companies collaborated on the Spacebus 100 design A Molniya communications satellite was launched into 12 hour elliptical orbit from Plesetsk on Oct 14 The Molniya launch vehicle consists of a Soyuz with an extra fourth stage the Blok L the fourth stage and payload are placed in low orbit and then the fourth stage ignites to place the payload in elliptical orbit The spacecraft launched on Oct 8 from Plesetsk is confirmed as a Foton materials processing flight Six small Gonets class comsats built by NPO Prikladnoi Mekhaniki of Krasnoyarsk were launched by a three stage Tsiklon rocket built by the Ukranian company NPO Yuzhnoye into 1400
