B.  Text of Launch Announcements.

1993-034A PROGRESS M-18, a C.I.S. automatic cargo craft, was launched from
          Baykonur cosmodrome to supply instruments and other supplies to
          MIR space station. Initial orbital parameters are period 88.7 min,
          apogee 258 km, perigee 194 km, and inclination 51.6 deg.

1993-033A RESURS F-2, a C.I.S. natural resources spacecraft, was launched from
          Plesetsk cosmodrome by a Soyuz booster at 10:15 UT. It carried
          spectro-photometers. Initial orbital parameters are period 88.9
          min, apogee 285 km, perigee 194 km, and inclination 82.6 deg.

1993-032A USA 91, a U.S.A. spacecraft in the GPS fleet, was launched by a 
          Delta rocket from Vandenberg AFB. It replaces the oldest of the
          GPS constellation, NAVSTAR 8, which was deactivated. The current 
          total of GPS spacecraft is 23. Initial orbital parameters are period 
          356 min, apogee 20,334 km, perigee 175 km, and inclination 34.9 deg.

1993-031B ARASENE, a French amateur radio relay spacecraft, was launched by an 
          Ariane 4 rocket from French Guiana Space Center. It was built by
          university students. Two of the three VHF relays are functioning
          normally. Initial orbital parameters are period 637 min, apogee
          36,075 km, perigee 223 km, and inclination 5 deg.

1993-031A ASTRA 1-C, a Luxembourg geostationary communications spacecraft, was
          launched by an Ariane 4 rocket from French Guiana Space Center. It
          is to join its two predecessors, 1-A and 1-B, at 19.2 deg longitude.
          It has a capacity of 16 transponders that cater for 48 channels, all
          to become operational by August 1993.

1993-030F COSMOS 2250, COSMOS 2249, COSMOS 2248, COSMOS 2247, COSMOS 2246, and
030E,030D COSMOS 2245, six C.I.S. spacecraft, were launched by a Tsiklon
030C,030B rocket. Approximate initial orbital parameters of the constellation
030A      are period 114 min, apogee 1,400 km, perigee 1,400 km, and inclination
          82.6 deg.



1993-029A COSMOS 2244, a C.I.S. spacecraft, was launched by a Soyuz rocket from
          Baykonur cosmodrome. Initial orbital parameters are period 89 min,
          apogee 274.4 min, perigee 204.4 km, and inclination 70.4 deg.

1993-028A COSMOS 2243, a C.I.S. spacecraft, was launched by a Soyuz rocket from
          Baykonur cosmodrome. Official response is unavailable at this time on
          reports that soon after launch the spacecraft broke up into 170
          pieces, the largest of which re-entered over the Indian Ocean.

1993-027A STS 55, a U.S.A. shuttle spacecraft, was launched. It carried a German-
          sponsored Spacelab D-2 for experiments in material science, life science,
          and technology, and for observations of Earth and celestial objects.
          Initial orbital parameters are period 90.5 min, apogee 306 km, perigee
          298 km, and inclination 28.4 km. 

1993-026A ALEXIS, a U.S.A. spacecraft, was launched by a Pegasus rocket from off
          the coast near Edwards AFB. As of this time, it has not been possible
          to establish communications with the spacecraft. It carried an array
          of low-energy x-ray imaging sensors. Orbital parameters are not 
          available.


C.  Spacecraft Particularly Suited for International Participation (Category I).

    1. Spacecraft with essentially continuous radio beacons on frequencies less
than 150 MHz, or higher frequencies if especially suited for ionospheric or
geodetic studies.  ("NNSS" denotes U.S. Navy Navigational Satellite System;
* indicates updated/new information since the last issue.)
