B. Text of Launch Announcements.

1995-020A
PROGRESS M-24, a Russian cargo spacecraft was launched by a Soyuz-U (-V ?) rocket from Baykonur cosmodrome at 19:34 UT to dock with and transfer 2.4 tonnes of supplies to the MIR space station; it docked at 21:01 UT on April 11. Initial orbital parameters were period 88.6 min, apogee 242 km, perigee 193 km, and inclination 51.6 deg.
1995-019A
MSAT is an American spacecraft. No information on the payload is available. Initial orbital parameters were period 721 min, apogee 20,334 km, perigee 20,176 km, and inclination 26.4 deg.
1995-018A
OFEQ 3 is an Israeli surveillance satellite that was launched westward by a Shavit launcher at 11:16 UT from the Palmahim launch site. Initial orbital parameters of the 189 kg/180 W spacecraft were period 95.6 min, apogee 729 km, perigee 367 km, and inclination 143.3 deg.
1995-017C
MICROLAB 1 is an American minisatellite that was launched by a Pegasus rocket carried aloft by an L-1011 aircraft flying out of Vandenberg AFB. The main instrument is a global lightning mapper; the other is a radio receiver to monitor the transmission from any GPS spacecraft that appears near the horizon and to infer temperature and humidity in its path. Initial orbital parameters were period 99.6 min, apogee 747 km, perigee 734 km, and inclination 69.9 deg.
1995-017B, 1995-017A
ORBCOMM FM2 and ORBCOMM FM1 are American minisatellites that were launched by the same Pegasus rocket which launched the MICROLAB 1. The main payload is a transponder to relay the GPS-determined locations of cargo trucks, and data from oil pipeline monitors. Both spacecraft are currently experiencing transmission or reception problems; efforts are underway to remedy the problems. The initial orbital parameters were period 99.6 min, apogee 747 km, perigee 734 km, and inclination 69.9 deg.
1995-016B
HOT BIRD 1 is a geostationary communications spacecraft of the European EUTELSAT consortium that was launched along with BRASILSAT-B2. After parking at 13-E longitude, it will provide live television (only) coverage to the European and Mediteranean countries.
1995-016A
BRASILSAT-B2 is a Brazilian geostationary communications spacecraft that was launched by an Ariane rocket from Kourou, French Guiana, at 23:14 UT. After parking at 65-W longitude, the 1,780 kg spacecraft will provide telephone, television, and data transmission services to Brazil and its southern neighbors by means of 24 C-Band and several X-Band transponders.
1995-015A
USA 109, better known as DMSP/F13, is an American science/military spacecraft that was launched from Vandenberg AFB by an Atlas-E rocket at 14:05 UT. It carries the same set of instruments that have been carried in the earlier DMSPs: imaging photometers, electron/ion flux monitors, and others. Initial orbital parameters were period 101.9 min, apogee 851 km, perigee 845 km, and inclination 98.8 deg.

C. Spacecraft Particularly Suited for International Participation

    NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft. Some data are on line for electronic access. Please contact the NSSDC Request Coordination Office, Code 633, NASA/GSFC, Greenbelt, Maryland, 20771, U.S.A., for specific information (REQUEST@NSSDCA.GSFC.NASA.GOV). Precomputed trajectory files and orbital parameters of many magnetospheric and heliospheric science-payload spacecraft may be FTP'ed from NSSDC's ANON_DIR:[000000.ACTIVE] and its several subdirectories. (See About the SPACEWARN Bulletin for access method; a file in the ACTIVE directory named AAREADME.DOC, outlines the contents.)
