B. Text of Launch Announcements.
2002-037A Cosmos 2392 (also known as Arkon) is a Russian military reconnaissance satellite that was launched by a Proton-K rocket from Baikonur at 15:13 UT on 25 July 2002. The 2.6 tonne (with fuel) satellite carries a high-resolution imager with a 1.6 meter mirror telescope to provide images at a resolution of one meter. The images will be distributed for sale by a Russian company. The initial orbital parameters were period 120 min, apogee 1,834 km, perigee 1,507 km, and inclination 63.5 deg.
2002-036A,  2002-036B Cosmos 2390 and Cosmos 2391 Cosmos 2391 and Cosmos 2390 are Russian military communications satellites that were launched by a Cosmos-3M rocket from Plesetsk at 06:36 UT on 8 July 2002. (These 200 kg satellites are reported to belong to the "Strela-3 class" of satellites.). The initial orbital parameters of both were close: period 115.7 min, apogee 1,507 km perigee 1467 km, and inclination 82.5 deg.
2002-035B N-STAR 3 is a Japanese geostationary communications spacecraft that was launched (along with STELLAT 5) by an Ariane 5 rocket from Kourou at 23:22 UT on 5 July 2002. The 1,625 kg (with fuel), 1,400 W triaxially-stabilized satellite will provide mobile telephony, data transfer and maritime communications to Japan and neighboring area through its S- and C-band transponders after parking over 135 deg-E longitude.
2002-035A STELLAT 5 is a European geostationary communications spacecraft that was launched (along with N-STAR 3) by an Ariane 5 rocket from Kourou at 23:22 UT on 5 July 2002. It will provide television and two-way Internet services to Europe, North Africa and Middle East through its 35 Ku-band and 10 C-band transponders after parking over 5 deg-W longitude.
2002-034A CONTOUR CONTOUR (Comet Nucleus Tour) is an American (NASA) heliospheric spacecraft that was launched by a Delta 2 rocket from Cape Canaveral at 06:47 UT on 3 July 2002. The 970 kg will remain in Earth-orbit until about 15 August 2002, when it will begin the heliospheric voyage of four or more years to meet at least two comets, Comet Encke on 12 November 2003, and Comet Schwassmann-Wachmann 3 (SW3) on 19 June 2006, at a distance of 100 km from each nucleus. Before each encounter, it will undergo a speed boost by an Earth swingby. It carries four instruments to image the comets and analyze the emitted dust and gaseous material.

CRISP (Contour Remote Imager/Spectrograph) is a 12 kg, 36 W instrument. It will provide one panchromatic and nine color images of the comets at frequent intervals, through its 10-cm aperture, 68-cm focal length telescope. It will also provide UV spectra in 256 channels.

CFI (Contour Forward Imager) is a 4 kg, 2 W instrument that will scan and provide images of far-away comets, to be imaged later by CRISP at close range.

NGIMS (Neutral Gas Ion Mass Spectrometer) is a 9 kg, 23 W instrument that will analyze the gaseous emissions from the cometary coma.

CIDA (Comet Impact Dust Analyzer) is a Time-of-Flight (ToF) ion mass spectrometer that will measure the mass distribution of the impacting dust particles.

More details of the mission and the experiments are available in http://www.contour2002.org/, and http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=2002-034A.

The Principal Investigator for all the CONTOUR experiments is Joseph Viverka of Cornell University, Ithaca, NY. The Project Manager is Edward Reynolds of the Applied Physics Lab/JHU, Laurel, MD. The initial parameters of the geocentric phase are period 2,482 min, apogee 108,498 km, perigee 183 km, and inclination 30.2 deg.
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.

    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.colorado.edu/geography/gcraft/notes/gps/gps_f.html 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 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.

    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, 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.

  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, http://oig1.gsfc.nasa.gov/scripts/foxweb.exe/app01?. 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".

    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.)

    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. (wwas@nssdca.gsfc.nasa.gov)
