B. Text of Launch Announcements.

1994-076C, 1994-076B, 1994-076A
Cosmos 2296, Cosmos 2295, and Cosmos 2294 are the three latest additions to the Russian fleet of global positioning spacecraft (GLONASS), and were launched by a Proton-K rocket from Baykonur cosmodrome at 00:09 UT. The fleet now totals 21 spacecraft plus a reserve; three more spacecraft that are to be launched in 1995 will complete the constellation of 24 spacecraft. The GLONASS series enables position measurement at land or sea within an error of 100 meters. Initial orbital parameters were period 2 hr, apogee/perigee 19,000 km, and inclination 71 deg. (The three spacecraft will be listed in section C-3 of a later issue, after additional data could be procured.)

PROGRESS M-25, a Russian automatic cargo ship, was launched from Baykonur cosmodrome by a Soyuz-U rocket, and headed to dock with the MIR space station to provide supplies to the station. The cargo ship carried more than two tons of supplies, and a returnable RADUGA capsule to bring back about 150 kg of experimental results from MIR. Initial orbital parameters were period 92.4 min, apogee 394 km, perigee 342 km, and inclination 51.6 deg.

RESURS-01, a Russian natural resources spacecraft, was launched from Baykonur cosmodrome by a Zenit-2 rocket at 05:46 UT in a Sun-synchronous orbit. This is the third of the RESURS-01 series , and a likely alternative name may be RESURS 1-3. Initial orbital parameters were period 98 min, apogee 691.4 km, perigee 663.8 km, and inclination 98 deg.

CRISTA-SPAS, a German spacecraft, was released from STS 66 on 4 November and captured back on 12 November. It carried spectraphotometers to monitor gases in the middle atmosphere and lower thermosphere. Orbital parameters were close to those of STS 66.

STS 66, a U.S.A. shuttle spacecraft, was launched from Cape Canaveral at 06:59 UT. The primary payload was the ATLAS-3 laboratory containing two instruments (SOLCON, and SOLSPEC) to measure solar emissions in the visible and UV bands, and a UV backscatter monitor to measure ozone concentrations. The shuttle also carried many pregnant and nonpregnant rats for biological studies. Initial orbital parameters were period 90.6 min, apogee 310 km, perigee 296 km, and inclination 57 deg.

Cosmos 2293, a Russian military spacecraft, was launched by a Tsiklon-2 rocket. The initial orbital parameters were period 92.7 min, apogee 436 km, perigee 412 km, and inclination 65 deg.

Wind is a U.S.A. spacecraft in the International Solar Terrestrial Program (ISTP), and was launched by a Delta-2 rocket from Cape Canaverl at 23:31 UT. It carried instruments to measure the solar wind plasma and magnetic field, besides several instruments to measure very energetic particles and gamma rays. After several orbits extending to close proximity of the Moon (at about 60 Earth-radii), and involving several thrust-firings during that phase, the spacecraft will eventually reach the first Lagrangian point (L-1) located at about 275 Earth-radii in the Sun-ward direction, and orbit around that point. Orbital parameters are very variable even during the first two years.

ASTRA 1-D is a geostationary spacecraft of the European Space Society that was launched by an Ariane 42P rocket from Kourou in French Guiana at 00:37 UT, to provide direct TV and radio broadcast to most of Europe, after reaching the parking longitude of 19.2 E. It carried 18 transponders.

ELECTRO is a Russian geostationary weather spacecraft that was launched from Baykonur cosmodrome by a Proton rocket. It will provide cloud cover, and sea temperature maps, along with the data on the upper boundaries of clouds and wind speeds, to enable hurricane, floods, and typhoon warnings. It will be parked at 76-E longitude over the Indian ocean just south of India.
