B. Text of Launch Announcements.

2000-017A IMAGE
(Imager for Magnetopause-to-Aurora Global Exploration) is an
American magnetospheric science spacecraft that was launched by a
Delta 2 rocket from Vandenberg AFB at 20:35 UT. The 494 kg, 250 W,
spin-stabilized (2 min period) octagonal (2.25 m wide and 1.52 m
high) spacecraft carries six instruments: HENA (High Energy Neutral
Atom; 10-500 keV) imager, MENA (Medium Energy Neutral Atom; 1-30
keV) imager, LENA (Low Energy Neutral Atom; 10-500 eV) imager, FUV
(Far Ultra-Violet) imager, EUV (Extreme Untra-Violet) imager, and
RPI (Radio Plasma Imager). HENA, MENA, and LENA synthesize images
from the arrival directions and
mass/energy of each neutral particle. (The energetic neutrals form
an ephemeral population when energetic ions charge-exchange with
the thermal population.) FUV carries three separate detectors: WIC
(Wide Angle Camera) to image aurora in a broad band and high spatial
resolution, SI (Spectroscopic Imager) to image aurora at selected
wavelengths, and GEO (GEOcorona) to image overall magnetospheric
hydrogen atoms. EUV images the population of He+ through the resonantly
scattered solar radiation at 30.4 nm wavelength.
Finally, RPI consists of a pulsed transmitter (stepped 3 kHz
to 3 MHz, 134 W peak) and a receiver, backed a radial dipole of 500
m length, another orthogonal 500 m dipole, and an axial 20 m dipole,
to get echoes from boundary regions in the magnetosphere.

http://image.gsfc.nasa.gov/
and the links
from it. Initial orbital parameters were period 856 min, apogee
45,995 km, perigee 993 km, and inclination 89.9 deg
2000-016B INSAT 3B
is an Indian geosynchronous communications spacecraft
that was launched by an Ariane 5 rocket from Kourou at 23:29 UT.
The 2,070 kg (with fuel), 1.7 kW, triaxially stabilized spacecraft
carries 12 Ext-C-band (15 W), and three Ku-band (55 W) transponders
for rural educational and health service programs receivable by the
thousands of VSATs (Very Small Aperture Terminals) in India, and a
single S-band mobile satellite service (MSS) transponder for
relaying voice, data, and facsimilies from/to mobile telephones
with suit case sized “terminals”, after parking over 83 deg-E
longitude. On 28 March, it was moved from the transfer orbit to
the geosynchronous orbit and its solar arrays were deployed by the
Master Control Facility in Hasan, located in southern India.
2000-016A AsiaStar
is an American geosynchronous communications spacecraft
that was launched by an Ariane 5 rocket from Kourou at 23:29 UT.
The 2,777 kg, 5.6 kW, triaxially stabilized spacecraft will relay
digital radio broadcasts to East Asia after parking over 105 deg-E
longitude.
2000-015A Fregat RB/Cluster 2
is a Russian experimental upper stage rocket
body (Fregat), and a dummy payload (Cluster 2) to simulate the
soon (June/July 2000) to be launched ESA’s Cluster mission. Fregat
is a reusable rocket and was described in the launch text of
Fregat (2000-009A) contained in
SPX 556.
The separation of the
rocket body and the dummy was not planned, but the separation was
simulated successfully. The couplet was launched by a Soyuz-U rocket
from Baikonur at 18:28 UT. It is likely that after these and more
successful launches of the Fregat rocket, future commercial or
scientific launches of the Soyuz-Fregat combine will take place from
French Guiana. Initial orbital parameters were period 320 min,
apogee 18,019 km, perigee 245 km, and inclination 64.6 deg.
2000-014A MTI
(Multi-spectral Thermal Imager) is an American quasi-military
reconnaissance spacecraft that was launched by a Taurus rocket from
Vandenberg AFB at 09:23 UT. The program is cosponsored by the
Deparment of Energy, Office of Nonproliferation and National
Security. The 587 kg spacecraft carries visible and infrared
sensors in 15 spectral bands to spot cooling ponds adjacent to
nuclear reactors and dust content associated with uranium ore
processing. The collected data will also have spin-off benefits to
civilian research involving atmospheric ozone, water vapor, and
such. More details are available at
http://nis-www.lanl.gov/nis-projects/mti/.
Initial orbital parameters were period 96.6
min, apogee 614 km, perigee 577 km, and inclination 97.4 deg.
2000-013A Express 2A
is a Russian geosynchronous communications spacecraft
that was launched from Baikonur by a Proton-K rocket at 04:07 UT.
(USSPACECOM had tentatively named it Express 6A.) The 2,600 kg
spacecraft carries 12 transponders in C-band and five in Ku-band to
provide voice, data, and video communications in Russia from the
parked longitude of 80 deg-E, supplementing the existing fleet of
seven Gorizonts, two Expresses and an EKRAN-M. Expresses are
scheduled to replace the aging Gorizont fleet.

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.)

    Note:
    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. (“NNN” denotes no national name. SPACEWARN
    would appreciate 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
    http://www.utexas.edu/depts/grg/gcraft/notes/gps/gps.html#DODSystem
    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.
    Entries marked “*” are updates or additions to the 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
    Russia.

    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:
    http://www.rssi.ru/SFCSIC/english.html
    maintained by the Coordinational
    Scientific Information Center (CSIC),Russian Space Forces.

  4. Actual decays/landings of payload spacecraft and rocket bodies (R/B)
