B. Text of Launch Announcements.

2002-033A Progress-M46
is a Russian automatic cargo carrier that was launched
by a Soyuz-U rocket from Baikonur at 06:36 UT on 26 June 2002. It
delivered 2.5 tonnes of fuel, food, oxygen, water and equipment to
the International Space Station after docking with the ISS at
07:22 UT on 29 June 2002. The initial orbital parameters were
period 88.6 min, apogee 245 km, perigee 193 km, and inclination
51.7 deg.
2002-032A NOAA 17
is an American (NOAA/NASA) weather satellite that was
launched by Titan 2 rocket from Vandenberg AFB at 18:23 UT on 24
June 2002. The triaxially-stabilized, 1,500 kg (plus 760 kg fuel)
satellite with a length of 4.2 m and a diameter of 1.9 m has a solar
array of 16.8 square-meters that generates 830 W power. It carries
several Earth weather-related instruments, named AVHRR-3, HIRS-3,
AMSU-A, AMSU-B, and SBUV-2; and a space weather package named SEM.
The data are stored on-board and transmitted over Fairbanks (Alaska)
and Wallops Island (Virginia). The Program Manager (PM) for NOAA 17
is Karen Halterman of the Goddard Space Flight Center. (No one is
listed as PS or PI.) More details on NOAA 17 are available in
Initial orbital parameters were period 101.2 min, apogee 823 km,
perigee 807 km, and inclination 98.8 deg.

AVHRR-3 (AdVanced High Resolution Radiometer 3) has six wavelength
channels (0.58-0.68, 0.625-1.00, 1.58-1.64, 3.55-3.93, 10.3-11.3, and
11.5-12.5 microns), of which the first three monitor the back-scattered
solar radiation, and the second three monitor the emissions
from land, sea, ice and clouds, all with a spatial resolution of 1.1 km.

HIRS-3 (High-resolution InfraRed Sounder 3) monitors the atmosphere
in 20 closely spaced wavelength channels (one in visible, seven in
shortwave IR, and 12 in longwave IR channels) to provide the
vertical temperature profile out to 40 km, at a spatial resolution
of about 20 km.

AMSU A/B (Advanced Microwave Sounding Unit, A and B) capture the
water vapor emissions to obtain tropospheric humidity profile, with
help from HIRS-3 data. AMSU-A operates at 15 channels in the range
23.8-89.0 GHz and AMSU-B operates in five channels in the range
89-183 GHz.

SBUV-2 (Solar Back-scatter UV 2) monitors the solar irradiance and
the back-scattered radiations in 12 bands covering the wavelength
range, 160-400 nm to obtain total ozone and its vertical

SEM-2 (Space Environment Monitor 2) carries two detectors: TED (Total
Energy Detector) captures the particle radiation in several bands
covering 0.05-20.0 keV; and MEPED (Medium Energy Proton and Electron
Detector) covers the 30 keV-6.9 MeV range in several channels.

SAR (Search And Rescue) instruments monitor the international
emergency radio bands at 121.5, 243.0, and 406.05 MHz. The SARR
instrument captures the calls in all three frequencies, only to
transpond instantaneously to a ground station, if any, in sight.
The SARP instrument captures a 406.5 MHz call, stores it on-board
so as to retransmit over known ground stations. The ground stations
Doppler-analyze the signals to locate the position of the distress
site with an accuracy of a few kilometers.

2002-031A, 2002-031B Iridium 97 and Iridium 98
are the two American Iridium
communications satellites that were launched by a Rockot rocket from
Plesetsk at 09:34 UT on 15 May 2002. (Rockot is a modified SS-19
ICBM.) These two 690 kg satellites augment the fleet of in-orbit
spares to 14 satellites that are intended as backup to the
operational fleet of 66 Iridiums. The fleet provides L-band links
between mainly mobile telephones, many of which have been recently
DoD/Pentagon-owned. The initial orbital parameters of both were
close: period 98.0 min, apogee 670 km, perigee 658 km, and
inclination 86.6 deg.
2002-030A Galaxy 3C
is an American geostationary communications spacecraft
that was launched by a Zenit 3SL rocket from the Odyssey Launch
Platform on the equatorial (154 deg-W longitude) Pacific Ocean at
22:39 UT on 15 June 2002. The 2.8 tonne satellite will provide
direct-to-home broadcast of video and internet services to the
subscribers in the USA and Latin America through its 24 C-band
(34 W) and 53 Ku-band (120 W) transponders after parking over 95
deg-W longitude
2002-029A Express 4A
(also named in the press as Express 41R and Express
41P) is a Russian geostationary communications spacecraft that was
launched by a Proton-K rocket from Baikonur at 01:15 UT on 10 June
2002. The 1.6 tonne spacecraft will provide television and radio
services in digital format to Russia and neighboring countries.
2002-028A STS 111
is an American shuttle spacecraft that was launched from
Cape Canaveral at 21:23 UT on 5 June 2002. It carried a crew of
seven astronauts (four American, two Russian and a French) and
material to the International Space Station (ISS). Three of the
astronauts (one American and two Russians) will remain on ISS for
four months, relieving its earlier crew of three. The crew repaired
a malfunctioning gyroscope and installed debris shields on the Zvesda
module. They repaired the wrist joints on the Canadian robotic
arm/crane, and also facilitated its (eventual) full mobility across
the full length of the ISS. The shuttle returned on 19 June 2002 to
Edwards AFB in California with four of its crew, plus the three
astronauts who had stayed on the ISS for over six months. The
initial orbital parameters of the shuttle were period 91.9 min
apogee 387 km, perigee 349 km, and inclination 51.6 deg.
2002-027A Intelsat 905
is a geostationary communications spacecraft of
the international ITSO consortium that was launched by an Ariane
44L rocket from Kourou at 06:44 UT. It will provide voice, video,
and internet services to all countries adjoining the Atlantic Ocean
through its 72 C-band and 22 Ku-band transponders after parking over
24.5 deg-W longitude.(It replaces the aging Intelsat 603, which had
been retrieved from a useless orbit by a space Shuttle crew in 1992
and ejected back to be functional till 2002.)
2002-024A, 2002-024B Haiyang 1 and Fengyun 1D
are the official names of the two Chinese
spacecraft that had been tentatively named as Payload A
and Payload B in SPX 583.

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.
    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.

    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:  [directory /igscb]

    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
    It provides many links to GPS related databases.

  3. Russian Global Navigational (Positioning) Spacecraft, GLONASS
    constellation. (SPACEWARN requests updates/additions from readers to this list.)

    All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers
    (nnnn) invoked by USSPACECOM have often differed from the numbers (NNNN)
    associated in Russia; when different, the USSPACECOM COSMOS numbers are shown
    in parentheses. The corresponding GLONASS numbers are Russian numbers, followed
    by the numbers in parentheses that are sometimes attributed to them outside

    The operating frequencies in MHz are computed from the channel number K.
    Frequencies (MHz) = 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 at:
    maintained by the Coordinational
    Scientific Information Center (CSIC),Russian Space Forces.

    The latest addition to the GLONASS fleet are Cosmos 2380, Cosmos 2381, and
    Cosmos 2382.

  4. Visually bright objects.

    A comprehensive list of visually bright
    objects with their two-line orbital elements is available from USSPACECOM, via a
    NASA site, The list, however,
    does not include visual magnitudes, but are expected to be brighter than
    magnitude 5.

  5. Actual decays/landings of payload spacecraft and rocket bodies (R/B)
    only. No further information is available.
