B. Text of Launch Announcements.

2001-022A Cosmos 2377
is a Russian military spacecraft that was launched
from Plesetsk cosmodrome by a Soyuz-U rocket at 17:55 UT on 29 May
2001. Initial orbital parameters were period 89.7 min, apogee 382
km, perigee 176 km, and inclination 67.1 deg.
2001-021A Progress M1-6
is a Russian automatic cargo carrier that was
launched from Baikonur by the new Soyuz-FG rocket at 22:42 UT on 21
May 2001. It carried 2.5 tonnes of food, fuel, water, and life-support
material to deliver to the International Space Station
(ISS). Nearly one tonne of the fuel is for raising the altitude of
the ISS. It docked automatically at a port on the Zvezda module on
23 May at 00:15 UT. Initial orbital parameters were period 90.4 min,
apogee 316 km, perigee 270 km, and inclination 51.6 deg.
2001-020A USA 158
is an American geosynchronous military spacecraft of the
National Reconnaissance Office (NRO) fleet. It was launched by a
Delta 2 rocket from Cape Canaveral AFS at 17:45 UT on 18 May 2001.
It is reported to be a laser communications technology demonstrator.
2001-019A PAS 10
(PanAmSat 10) is an American geosynchronous communications
spacecraft that was launched from Baikonur by a Proton-K rocket
(with a DM-3 booster) at 01:11 UT on 15 May 2001. The 3.7 kg (with
fuel) satellite carries 48 transponders (24 in C-band and 24 in Ku-band)
to provide direct-to-home video channels to Europe, Middle-East,
and South Africa after parking over 68.5 deg-E longitude.
2001-018A XM 1,
also known as Roll, is an American geosynchronous relay
satellite that was launched by a Zenit rocket from a floating
platform, Odyssey on the equatorial Pacific ocean at 10:10 UT on
8 May 2001. (XM 2, also known as Rock, was launched in March 2001.)
It will provide one hundred channels of digital music and
entertainment to motorists in North America after parking over 85

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. (“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:  [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.
    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

    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.

  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, 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.
