B. Text of Launch Announcements.

2002-040B MSG 1
(Meteosat Second Generation 1) is a European (Eumetsat
consortium) geostationary weather satellite that was launched by
an Ariane 5 rocket from Kourou at 22:45 UT on 28 August 2002.
The cylindrical, 2-tonne satellite will enable quicker and more
accurate weather forecast in Europe than in the past, after first
parking over 10 deg-E longitude for six months and later moving
the zero degree longitude. It carries two major instruments.
SEVIRI (Spinning Enhanced Visible and Infra-Red Imager) is a 12-
channel imager that will provide a set of surface and cloud-cover
images every 15 minutes at a spatial resolution of 1 km. Four of
the channels are in cloud- and soil-reflected visible wavelengths,
four infrared channels will measure temperature of clouds and sea-
surafce, and the remaining four infrared channels will provide water
vapor, ozone and carbon dioxide contents.

GERB (Geostationary Earth Radiation Budget) measures the radiation
coming from the Sun and the reflected/emitted radiation rom the
Earth to obtain the radiation balance.

Raw data from both instruments will be directly downlinked to
Darmstadt, Germany; the processed data will be uplinked to the
satellite to be rebroadcast to Europe and other regions.

Besides those two instruments, it carries receivers for weather-data
from remote/mobile sites, and a 406 MHz transponder for search-and-
rescue SOS operations conducted by the global COSPAS-Surat
organization. More details of the payload are available through

2002-040A Atlantic Bird
is a European (Eutelsat) geostationary communications
spacecraft that was launched by an Ariane 5 rocket from Kourou at
22:45 UT on 28 August 2002. The 2.7 tonne (dry mass), 5 kW satellite
will provide voice, video, and Internet services to Europe and
the eastern part of America through its 24 transponders after parking
over 12.5 deg-W
2002-039A Echostar 8
is an American geostationary communication spacecraft
that was launched by a Proton-K rocket from Baikonur at 05:15 UT on
22 August 2002. The 4.7 tonne satellite will provide digital TV
broadcast to North America through its 16 “spot beams” and 41
transponders in the Ku-band after parking over 110 deg-W longitude.
2002-038A Hot Bird 6
is a European (Eutelsat) geostationary communications
spacecraft that was launched by an Atlas 5/Centaur rocket from Cape
Canaveral at 22:05 UT on 21 August 2002. It was a maiden flight for
the Atlas 5 which has two stages (one a liquid oxygen and hydrogen,
the other a liquid oxygen and liquid hydrogen burner) and uses
Russian motors. The 4.9 tonne Hot Bird 6 will provide digital radio
and television coverage to Europe, North Africa and the Middle East
through its 28 Ku-band and four Ka-band transponders after parking
over 13 deg-E longitude.

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.

    Designations         Common Name                  Decay Date (2002)
    2002-037B (27471)  R/B(1) Proton-K                        26 July
    1999-072A (26040)  COSMOS 2367                            20 July

    2002-007B (27381)  R/B Ariane 44L                         01 July
    2001-034B (26885)  R/B(1) Delta 2                         01 July
  6. 60-day Decay Predictions.

    The USSPACECOM forecasts and maintains a
    list of decays of orbiting objects expected in the next 60 days , with fair
    accuracy. The list may be accessed through a NASA site,
    as follows:

    1. Select “OIG Main Page”.
    2. Select “Send Message to System administrator”, who will provide a login account.
    3. After getting an ID and a Password, click on “Registered User Login”.
      (Step (2) is not needed after obtaining an account.)
    4. Select “Continue”.
    5. Select “General information”.
    6. Select “Reports”.
    7. Select “Sixty Day Decay…”.

    Note: The login requirement is enforced due to the events on 11 September 2001.

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

    CONTOUR spacecraft (2002-034A) is reported to have lost contact with the
    ground control. A thruster was ignited on 15 August 2002 to boost it into
    a heliocentric orbit so as to obtain images of two comets over the next few
    years. But soon after the ignition there was no contact. Ground based
    telescopes seem to have photographed the spacecraft as two separate pieces.
    NASA has appointed panel to investigate the cause.

    The CRL, Kokubunji, Japan has notified us that NASDA expects to launch a
    geostationary DRTS (Data Relay Test Satellite) on 10 September 2002 by a
    H-IIA rocket.

    It appears that there is no national or international organization that
    defines the various alphabetically designated Communication and Broadcasting
    frequency bands. One of the extant lists has the following coverages. The
    Spacewarn Bulletin would appreciate input from the reader community to update
    the coverage status. (

                 L-Band   1.35-1.70 GHz
                 S-Band   1.70-2.30 GHz;   2.30-2.70 GHz
                 C-Band   3.40-4.20 GHz;   4.40-5.00 GHz; 5.725-8.40 GHz
                Ku-Band  10.00-13.25 GHz; 14.00-15.40 GHz
                 K-Bnad  17.30-24.05 GHz
                Ka-Band  25.25-31.80 GHz
