To quote from Microcom's Space Newsfeed for Spetember 28, 2003:
http://www.spacenewsfeed.co.uk/2003/28September2003.html BilSat-1, KAISTSat-4, Larets, Mozhayets-4, NigeriaSat-1 and UK-DMC Launched: 27 September 2003 Site: Plesetsk Cosmodrome, Russia Launcher: Kosmos 3M International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: BilSat-1 Owner: Tubitak-ODTU Bilten (Turkey) Contractor: Surrey Satellite Technology International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: KAISTSat-4 Contractor: Korea Advanced Institute of Science & Technology (KAIST) International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: Larets International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: Mozhayets-4 International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: NigeriaSat-1 Owner: National Space Research & Development Agency (Nigeria) Contractor: Surrey Satellite Technology International Number: 2003-042? Orbit: LEO, apogee: 681 km, perigee: 664 km: inclination: 98.2° Name: UK-DMC Owner: British National Space Centre (BNSC) Contractor: Surrey Satellite Technology This Kosmos 3M launch placed six microsatellites into LEO. Three of the satellites launched (BilSat-1, NigeriaSat-1 and UK-DMC) will form part of the Disaster Monitoring Constellation. Each satellite has a mass of about 100 kg. The first satellite in the constellation, AlSAT-1, was launched last November and is now fully operational. KAISTSat-4 will carry the SPEAR (Spectroscopy of Plasma Evolution from Astrophysical Radiation) ultraviolet telescope which will measure the glow over the whole sky from gas between the stars that has been heated by supernova blast waves, blazing hot stars and colliding interstellar clouds. The satellite will also carry other experiments to measure energetic particles bombarding the Earth's atmosphere and causing auroras. SPEAR also will work in conjunction with these experiments by looking downward to capture the auroral ultraviolet emissions. SPEAR will gaze away from the sun and, during the course of a year, steadily scan a thin wedge of the sky from north to south, moving one degree each day to complete a full-sky map in the far ultraviolet. For the second year, SPEAR will concentrate on particularly fascinating features in the sky that were identified in the all-sky survey. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
