The implementation of a comprehensive scientific program with the use of these two spacecraft and a network of geophysical observatories in various countries began after the separation. 1991-088A PRC 34, a communications satellite, was launched on December 28, 1991 by the PRC using the Long March 3 carrier rocket. The satellite has been placed in a high elliptical orbit with an apogee of 35,176 km. 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.

Launching Reports and Updated Information. 1. Postlaunch announcement. (This section covers only those reports that are sent directly to us by the national agencies.) Spacecraft Name: TELECOM-2A Country: France - launching pad in KOUROU (French Guiana) Launching Agency: CNES (Centre National d'Etudes Spatiales Launcher: Ariane 44L Obrit Type: Geostationary Orbital Position: 3 deg EST Initial On-Station Mass: 1380 km Transmitting Frequencies and Orbit Power C-Band (6/4 GHz) 10 transponders - 10 Watts each Ku-Band (14/12 GHz) 11 transponders - 55 Watts each X-Band (8/7 GHz) 5 transponders - 20 and 40 Watts Expected Life Duration: 10.25 years Spacecraft Mission: TELECOM-2 is a family of three communcations satellites: A, B, and C. The objectives of TELECOM-2A are to succeed the TELECOM-1 family (which reaches its end of life) providing for telephone, FAX, TV, and data transfer services between mainland and French overseas departments; government communications; high-rate data transfer for professional applications of French industrial firms; and TV retransmission for commercial channels. 2. Prelaunch announcement. (This section covers only those reports that are sent directly to us by the national agencies.) Spacecraft Name: ATLAS-1 (Atmospheric Laboratory for Applications and Science-1) Planned Launch Date: March 14, 1992 Country: United States of America Mission Description: The Spacelab Atmospheric Laboratory for Applications and Science (ATLAS) mission is a configured payload complement of experiments previously flown on the early Spacelab missions. The ATLAS-1 payload consists of experiments for atmospheric physics, plasma physics, solar physics, astronomy, and Earth observations. The Spacelab configuration consists of two pallets and an IGLOO which contains the standard Command and Data Management System elements.
