Text of Launch Announcements. 1999-035A FUSE (Far Ultraviolet Spectroscopic Explorer) is an American astronomical spacecraft that was launched by a Delta 2 rocket at 15:44 UT from Cape Canaveral. The 1,400 kg spacecraft carries a 2.4 m focal length telescope with a primary mirror made of four separated segments; two them are coated with silicon carbide (to reflect 90 - 110 nm wavelnghts ) and the other two with aluminum and lithium flouride (to reflect 100 - 119 nm). The focussed beams then fall on four separate (correspondingly coated) Rowland gratings that disperse the spectrum into four separate photon counting microchannel flat-plate detectors. A separate star tracking Fine Error Sensor (FES) enables location of the source and a pointing stability within 0.5 arcseconds so as to enable large integration times. While there have been other FUV satellites such as Copernicus, HST, etc., the investigative thrust on the FUSE data will be intergalactic clouds and interstellar clouds which, presumably, carry the pristine (Big Bang) deuteriums undepleted by the voracious consumption in steller cores. The D/H ratios so obtained may proxy the status of the universe minutes after the Bang. For more details, see http://fuse.pha.jhu.edu/. Initial orbital parameters were period 100 min, apogee 770 km, perigee 754 km, and inclination 25 deg. 1999-034A QUIKSCAT (QUIcKSCATterometer) is an American oceanographic satellite that was launched by a Titan 2 rocket from Vandenberg AFB at 02:15 UT. It will measure ocean winds and directions by monitoring wind-induced ripples by means of a microwave scatterometer. The scanning width is 1,800 km. The instrument is a followup to the scatterometer that was onboard the Japanese ADEOS spacecraft (1996-046A) that operated until 30 June 1997. It will also be onboard ADEOS 2, to be launched in 2000. Initial orbital parameters of the Sun-synchronous spacecraft were period 95.6 min, apogee 815 km, perigee 281 km, and inclination 98.7 deg. 1999-033A ASTRA 1H is the latest member of the ASTRA fleet of geosynchronous spacecraft owned and operated by SES consortium in Luxembourg. It was launched by a Proton-K rocket from Baikonur at 01:49 UT. The 2,300 kg spacecraft carries 30 Ku-band, 100 W transponders to provide direct-to-home voice and video programs after parking over 19.2 deg-E 1999-032A, IRIDIUM 14A and IRIDIUM 21A are the latest to join the American -032B IRIDIUM fleet of minisatellites to provide voice and data transmissions from/to mobile telephones located in areas beyond cellular networks. They were launched from Taiyuan in Shanxi province of PRC by a Long March 2C rocket. Initial orbital parameters were period 99 min, apogee 712 km, perigee 709 km, and inclination 86.5 deg. 1999-031A, GLOBALSTAR 52, 49, 25, and 47 are the latest to join the fleet 031B,031C, of communications spacecraft owned by that international consortium. 031D They were launched by a Delta 2 rocket from Cape Canaveral at 13:48 UT. The fleet enables voice and data links from/to phones far away from cellular networks. Initial orbital parameters of all four were similar: period 114 min, apogee 1,414 km, perigee 1,406 km, and inclination 52 deg. 1999-030B STARSHINE is a passive reflector that was released from STS 96 on 05 June 1999. (STS had been launched on 27 May 1999.) STARSHINE is a hollow sphere of 48 cm diameter and studded with 878 tiny mirrors which had been polished by school children in Zimbabwe, Pakistan and 16 other countries. Some 25,000 high school students around the world are expected to track the reflector during twilight hours. Initial orbital parameters of STARSHINE were period 92 min, apogee 395 km, perigee 376 km, and inclination 51.6 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. Updates or corrections to the list are possible only with information from the user community.) THE FULL LIST APPEARED IN SPX 545. (See http://nssdc.gsfc.nasa.gov/ spacewarn/) THE LIST WILL NOT BE REPEATED IN FUTURE ISSUES, UNTIL SIGNIFICANTLY REVISED AGAIN. 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]). FTP: igscb.jpl.nasa.gov [directory /igscb] WWW: http://igscb.jpl.nasa.gov/ E-Mail: igscb@cobra.jpl.nasa.gov The standard format of the GPS situation appeared in SPX-518. It will not be repeated since an excellent source of trajectory- and science-related GPS information is at URL http://www.utexas.edu/depts/grg/gcraft/notes/gps/gps.html#DODSystem. It provides many links to GPS-related data bases. The latest member of the GPS fleet is NAVSTAR 38 (1997-067A), launched on 6 November 1997. 3. Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation. (SPACEWARN requests updates or additions from readers to this list. An asterisk [*] indicates updates or additions to the list.) All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers invoked by USSPACECOM have sometimes differed from the numbers (NNNN) associated in Russia. The operating frequencies in MHz are computed from the channel number K. Frequencies (MHz) are L1 = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K. The standard format of the GLONASS situation appeared in SPX-545. It will not be repeated in view of the excellent updated source, with the URL http://www.rssi.ru/SFCSIC/glonass.html, maintained by the Coordinational Scientific Information Center (CSIC), Russian Space Forces. 4. Actual decays or landings of payload spacecraft and rocket bodies (R/B) only. No further information is available. Designations Common Name 1999 1986-031D (16686) R/B that launched Molniya 3-28 28 Jun 1999-033B (25786) R/B Proton-K 19 Jun 1969-084B (04120) R/B that launched Meteor 2 15 Jun 1994-043B (23186) R/B Long March 08 Jun 1999-024B (25728) R/B Delta 2 05 Jun 1994-079B (23414) R/B Atlas 2A 31 May 5. Miscellaneous Items. (This section contains information or data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.) The names of 1999-029A, -029B, and -029C that were launched by an Indian PSLV rocket were reported in SPX 547 as IRS-P4/OCEANSAT, KITSAT 3, and TUBSAT. However, USSPACECOM continues to list the names as KITSAT 3, TUBSAT, and OCEANSAT. We have contacted USSPACECOM and are awaiting their confirmation or correction. 6. Related NSSDC resources.

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. 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 be accessed through the World Wide Web (WWW). The URL is http://nssdc.gsfc.nasa.gov/spacewarn/ Users are encouraged to submit their comments and suggestions for the improvement of this bulletin to SPACEWARN Bulletin: WWAS@NDADSB.GSFC.NASA.GOV. 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: Occasionally, a list of bright, orbiting objects of visual magnitude 4 or brighter. The bulletin also carries launch dates, international IDs, 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 emails, news papers, and some Web sites.
