SPX-505 November 25, 1995 SPACEWARN BULLETIN 505 A publication of NASA NSSDC/WDC-A-R&S as the WWAS for IUWDS/COSPAR (All information in this publication were received between October 25, 1995 and November 25, 1995) A. List of New International Designations and Launch Dates.

Text of Launch Announcements. 1995-063A GALS 2 is a Russian television relaying geostationary spacecraft that was launched by a Proton-K rocket from Baykonur cosmodrome at 14:25 UT. The 2.5 ton spacecraft carries three multichannel high power transponders so that ground stations in the far-eastern Siberia and the Pacific coast countries can capture signals with small dishes. 1995-062A ISO (Infrared Space Observatory), an ESA spacecraft, was launched by an Ariane rocket from Kourou base in French Guiana at 01:20 UT. The 2.5 tonne spacecraft of height 5.3 m and diameter 2.3 m carries a telescope with a primary mirror of 60 cm diameter. The mirror feeds (a) a visual photopolarimeter at 2-245 microns, providing images at 100-200 micron wavelengths through two cameras, and spectra at 3-16 microns; (b) a camera to provide sky maps at 2.5-17 microns; and (c) a spectrometer at 2.5-45 microns. The 2,150 liters of liquid helium supply will enable about 20 months of operation of all instruments. A few days after launch, the orbital parameters were period 24 hr, apogee 70,500 km, perigee 1,000 km, and inclination 5.25 deg. 1995-061A STS 74 is an American shuttle spacecraft that was launched from Cape Canaveral to dock with the Russian space station, MIR. The main mission was the docking exercise to transport to/from MIR about 500 kg of supplies. The docking module that was carried by STS 74 was successfully installed on MIR and remained after the end of the mission whose purpose was to develop know-how's for building a proposed international space station, Alpha. Initial orbital parameters of the STS were period 92.4 min, apogee 396 km, perigee 391 km, and inclination 51.6 deg. 1995-060A USA 115, also known as MILSTAR 2, is an American military spacecraft that was launched from Cape Canaveral Air Station by a Titan 4 rocket. The geostationary 4,500 kg spacecraft will be parked at 4 deg, east longitude. Developed during the days of nuclear war threats, the jam-proof and virtually disruption-proof spacecraft has capability to transpond securely an extensive volume of information with simultaneous access to a thousand users. Its companion, MILSTAR 1, remains parked at 120 deg, west; four more will join the constellation during 1999-2002. 1995-059B SURFSAT (Summer Under-graduate Research Fellowship SATellite) is an American microsatellite that was designed to assist tests on the upgraded soft-/hardware at the Deep Space Network stations that are primarily dedicated to capture the weak signals from Heliospheric probes. The 55 kg spacecraft remained attached to the second stage of the Delta 2 rocket (that had launched RADARSAT 1). Initial orbital parameters were period 109.6 min, apogee 1,495 km, perigee 935 km, and inclination 100.6 deg. 1995-059A RADARSAT 1 is a Canadian remote sensing spacecraft that was launched from Vandenberg AFB by a Delta 2 rocket at 14:22 UT. It carries a synthetic aperture radar for mapping natural resources. Initial orbital parameters were period 100.6 min, apogee 790 km, perigee 785 km, and inclination 98.6 deg. 1995-058A COSMOS 2322, a Russian military spacecraft, was launched by a Zenit-2 rocket from Baykonur cosmodrome at 19:19 UT. Initial orbital parameters were period 101.97 min, apogee 877.9 km, perigee 851.9 km, and inclination 71 deg. C. Spacecraft Particularly Suited for International Participation. 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; an asterisk [*] indicates updated/new information since the last issue. Updates or corrections to the list are possible only with information from the user community.) THIS SECTION HAS NOT RECEIVED ANY USER INPUTS/UPDATES FOR A YEAR. THE CONTENT REMAINS THE SAME AS IN SPX-504. THE SECTION WILL BE REVIVED FROM TIME TO TIME WHEN A SIGNIFICANT VOLUME OF UPDATES WOULD BE AVAILABLE FROM THE USER COMMUNITY. 2. Global Positioning System satellites useful for navigational purposes and geodetic studies. ("NNN" denotes no national name. SPACEWARN Bulletin appreciates suggestions to update this list. An asterisk [*] denotes changes in this issue.) High precision (< 20 cm), GPS constellation tracking data obtained from the network of about 80 dedicated global stations that are of interest to geodetic study may be obtained through the following services provided by the International Association of Geodesy (IGS).

Miscellaneous Items. (This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.) 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 Request Office, NSSDC, 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 the last page of the bulletin for the access method; a file in the ACTIVE directory named AAREADME.DOC outlines the contents.) It can also be accessed through WWW URL: http://sscop1.gsfc.nasa.gov/ssc.html This html also enables executing several codes related to the orbits of many geocentric science payload spacecraft. The codes related to the heliospheric spacecraft trajectories can be executed through URL: http://nssdc/space/helios/heli.html SPACEWARN Bulletin ------------------ The Bulletin is intended to serve as an international communication medium for the rapid distribution of information on satellites and space probes. The material it contains is based on guidelines in the COSPAR Guide to Rocket and Satellite Information and Data Exchange, COSPAR Transactions #8, December 1972, and various Committee on Space Research (COSPAR) resolutions. Hard copy recipients and electronic accessers are encouraged to disseminate the bulletin to interested individuals and institutions in their regions or countries. All bulletins beginning with January 1991 (SPX-447) are now available on line; the SPX number increases by one for each succeeding month (for example, the January 1993 bulletin is SPX-471).

The bulletin may also be accessed through the World Wide Web (WWW). The URL is http://nssdc.gsfc.nasa.gov/spacewarn/spacewarn.html. Users are urged to submit their comments and suggestions for the improvement of this bulletin to SPACEWARN Bulletin, World Data Center-A for Rockets and Satellites, Code 633, Goddard Space Flight Center, Greenbelt, Maryland 20771 U.S.A. Categories of Spacecraft To improve the effectiveness of international distribution of satellite and space probe information via the SPACEWARN system, spacecraft are identified in categories according to the urgency and detail of information needed by the scientific community as follows: CATEGORY 1: Spacecraft that carry essentially continuous telemetry or radio beacons, usually on frequencies less than 150 MHz. CATEGORY 2: GPS constellation of positioning/navigational spacecraft. CATEGORY 3: GLONASS constellation of positioning/navigational spacecraft. CATEGORY 4: Occassionally, a list of bright, orbiting objects of visual magnitude 4 or brighter. The bulletin also carries launch dates, international ID's and USSPACECOM catalog numbers, followed by a brief outline of the payload and orbital parameters, re-entry of major objects, and miscellaneous sections. These data are based on launch announcements or on information received from individuals, launching authorities, FBIS and USSPACECOM telexes, and news magazines.
