B. Text of Launch Announcements.

2001-017A Soyuz-TM 32
is a Russian passenger craft that was launched from
Baikonur by a Soyuz-U rocket at 07:37 UT. It carried a three man
crew (two Russian and one adequately trained, but a nonprofessional
American) to the International Space Station, ISS. It docked
automatically with the ISS at 07:57 UT on 30 April, just a few hours
after the shuttle STS 100 undocked. The crew will stay for a week.
The initial orbital parameters were period 90.3 min, apogee 326
km, perigee 254 km, and inclination 51.6 deg.
2001-016A STS 100
is an American shuttle spacecraft that was launched from
Cape Canaveral at 18:41 UT to dock with the International Space
Station (ISS). It carried a crew of four Americans, one Russian, one
Canadian and one Italian. The main mission was to install an 18
meter, 1,700 kg Canadian robotic arm named Canadarm-2 on the ISS,
and to transport an Italian cargo container, Raffaello, which
delivered 4,500 kg of supplies and equipment to the station. It
docked with the ISS at 13:59 UT on 21 April. The robotic arm was
hooked to the ISS with the help of the shuttle’s own 16 meter arm,
and two of the crew members. The seven-joint arm was not permanently
bolted to the ISS, and will crawl along the exterior walls under
computer control, temporarily anchoring wherever needed. There was a
sequential failure of the three onboard computers on the ISS, but
after four days of effort a backup computer was activated sufficiently
to enable the Canadarm-2 to hand over its own packing crater
to the shuttle arm. STS 100 undocked from the ISS on 29 April after
retrieving Raffello and landed at Edwards AFB
in California on 01 May. Initial orbital parameters were period
92.3 min, apogee 394 km, perigee 377 km, and inclination 51.6 deg.
2001-015A GSat 1
is an Indian, 1,500 kg (scaled-down) test model of a future,
geosynchronous communications spacecraft. It was launched by a GSLV-D1
rocket from Shriharikota (at 13 deg-N and 80 deg-E, on the
eastern coast of India) at 10:13 UT. The expectation/test was
on the 400 tonne rocket assembly which is an augmented version of
the well-proven PSLV rocket, with a third cryogenic stage. The
motor for the cryogenic, hydrogen-oxygen stage had been purchased
from Russia. After a series of gas burns to lift the spacecraft
from the transfer orbit (180 km x 32,000 km with an inclination of
19.2 deg), and move the orbital plane to the equator, the GSat 1
ran out of a necessary 10 kg more of fuel. Preliminary analysis
revealed a shortfall of 0.5% in the thrust, probably of the third
stage motor, that resulted in a short fall of the transfer orbit
apogee. In the end, the parameters of the drifting (about 13 deg/day)
orbit were period 23 hours, apogee 35,665 km, perigee 33,806
km, and inclination 0.99 deg. The fully functional transponders and
transmitters on board may be deactivated if the International
Telecommunications Union so advises.
2001-014A Mars Odyssey
is an American heliospheric spacecraft that was
launched by a Delta 2 rocket from Cape Canaveral at 15:02 UT. It is
scheduled to arrive near Mars on 24 October 2001. After a thruster
firing to slow it down, it will circle the planet in a highly
elliptical orbit with a period of 25 hours. With the help of
aerobraking during the next 76 days, it will reach a Sun-synchronous
polar orbit at an altitude of 400 km and with a period
of about two hours, and initiate a 917 Earth-days long mapping
program. It will also serve as a communications relay for the
American and international landers expected to arrive in 2003/2004.
In the Martian orbit, it will map the distribution of elements and
minerals on the surface, the distribution of hydrogen (embedded in
water ice) and the radiation environment. The second is to assess
the likelyhood of past or present life, and the third is to assess
the radiation hazard to manned missions. The three major instruments
on board are THEMIS (Thermal Emission Imaging System at the visible
and infrared light) for the distribution, at 100 meter resolution,
of minerals that form only in the presence of water, GRS (Gamma Ray
Spectrometer) for determining hydrogen and other elements, and MARIE
(presumably, MArs RadIation Environment) for determining the
radiation hazard. THEMIS will also enable site selection for a
future manned landing. THEMIS is expected to provide 15,000 images,
each covering 20 x 20 km. GRS carries two neutron monitors also.
The gamma rays and neutrons come out of the surface in distinct,
element-specific energies, released by cosmic ray bombardment. The
site, http://mars.jpl.nasa.gov/odyssey/ is a good source for more
details.
2001-013A Ekran-M 18
is a Russian geosynchronous communications spacecraft
that was launched by the new/upgraded Proton-M rocket from Baikonur
at 03:47 UT. The two tonne spacecraft will provide direct-to-home
video and voice channels to Siberia and far-eastern regions.
(Proton-M can launch satellites 1.5 tonnes heavier than those
launched by Proton-K, uses environment-friendly fuel that, in fact,
will be fully burnt before the rocket re-enters, and its re-entry
location can be controlled to a small, specific location. The fourth
stage of the rocket is the well tested Breeze-M which may soon
by replaced by a crygenic hydrogen-oxygen stage named KVRB, so
as to compete with Ariane-5’s capability. Ekran-M 18 will replace
the recently failed Ekran-M 15 that has been operating since
October 1992, after parking near 105 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.)

    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.

    The latest addition to the GPS fleet is Navstar 50 (2001-004A).

  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. Visually bright objects.

    A comprehensive list of visually bright
    objects with their two-line orbital elements is available from USSPACECOM, via a
    NASA URL, http://oig1.gsfc.nasa.gov/files/visible.tle. 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.
