B. Text of Launch Announcements.

1993-052A

Progress M-19, a C.I.S. automatic cargo craft, was launched at 22:23 UT to dock with and deliver supplies to MIR space station. Initial orbital parameters are period 88.5 min, apogee 243 km, perigee 192 km, and inclination 51.6 deg.

1993-051A

Cosmos 2261, a C.I.S. spacecraft, was launched from Plesetsk cosmodrome by a Molniya booster. Initial orbital parameters are period 11 hr, 48 min; apogee 39,400 km; perigee 613 km; and inclination 62.8 deg.

1993-050A

NOAA 13, a U.S.A. meteorological spacecraft, was launched from Vandenberg Air Force Base by an Atlas-E rocket. It carried instruments to monitor atmosphere and clouds; also on board were instruments to monitor energetic electrons and protons. It has relaying capability for data gathered from floating buoys, balloons, and remote ground stations. There have been no radio communications with the spacecraft since August 21, 1993, because of failure of power from the solar panels to the instruments. Initial orbital parameters are period 102 min, apogee 876 km, perigee 860 km, and inclination 98.9 km.

1993-049A

Molniya 3-45, a C.I.S. communications spacecraft, was launched from Plesetsk cosmodrome by a Molniya booster at 00:52 UT. Initial orbital parameters are period 11 hr, 42 min; apogee 39,147 km; perigee 455 km; and inclination 62.7 deg.

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. To see a list select here.

2. Global Positioning System satellites useful for navigational purposes and geodetic studies. To see a list select here.

3. Actual decays/landings of payload spacecraft and rocket bodies (R/B) only. Additional information is not available.

4. Miscellaneous Items. (This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.)

   Mars Observer (1992-063A) is reported to have lost contact with the tracking stations since August 20, 1993, just prior to the scheduled Mars orbital phase.

   Hipparcos (1989-062B) ended its mission with the final loss of communication with the ground stations. During its mission it has provided accurate positions of 100,000 stars.
