B. Text of Launch Announcements.

2004-032A	Progress-M 50 is a Russian cargo carrier that was launched by a Soyuz-U rocket from Baikonur at 05:03 UT on 11 August 2004. It carried 2.5 tonnes of food, fuel, air and water to the International Space Station (ISS). It docked automatically with the Zvezda module of the ISS at 05:02 UT on 14 August 2004. In anticipation of the docking, the previously docked Progress-M 49 was undocked on 30 July, carrying a load of trash to de-orbit and burn up. The initial orbital parameters were period 91.7 min, apogee 363 km, perigee 352 km and inclination 51.6°.
2004-031A	Amazonas is a Spanish geostationary communications satellite that was launched by a Proton-M rocket from Baikonur at 22:32 UT. on 4 August 2004. The 4.5 tonne satellite carries 36 Ku-band, and 27 C-band transponders to provide broad-band video and internet services to the North and South American continents and western Europe after parking over 61° W longitude.
2004-030A	MESSENGER is an American (NASA) interplanetary probe that was launched by a Delta 2 rocket from Cape Canaveral at 06:16 UT on 3 August 2004. It will eventually flyby and then orbit around Mercury in 2011. Meanwhile it will undergo encounters with Earth (in August 2005) and with Venus (in October 2006, and June 2007). There will be three flybys over Mercury (in January 2008, October 2008, and September 2009) in order to initiate a capture orbit in March 2011. The orbit around Mercury will be highly elliptical, with altitudes ranging from 200-15000 km. The orbital period will be about 12 hours, and inclination about 80°. The 1.1 tonne, 640 W spacecraft carries several imagers and spectrometers at a temperature of -183° C. They are outlined below. The Principal Investigator is Sean C. Solomon of the Carnegie Institution in Washington, D.C. He will be backed by instrument-specific Lead Scientists. The Project Scientist is Ralph L. McNutt, Jr. at APL/JHU. Additional information on the mission is available in http://messenger.jhuapl.edu/. MDIS (Mercury Dual Imaging System) is a 7.9 kg, 10 W instrument and consists of wide-angle (10.5° FoV) and a narrow-angle (1.5° FoV) imagers in visible light, to image landforms in directions commanded by the investigating team. The wide-angle camera carries CCDs to map in 12 wavelength bands covering 400-1100 nm. The panchromatic narrow-angle camera will provide 18-meter resolution images. Louise Prockter (APL/JHU) is the Lead Scientist. GRNS (Gamma-Ray and Neutron Spectrometer) is a 13.1 kg, 23.6 W instrument that will capture the gamma rays and neutrons emitted by the atoms on Mercury’s surface and in the atmosphere that arise from the impact of cosmic rays. Edgar Rhodes (APL/JHU) is the Lead Scientist. XRS (X-Ray Spectrometer) is a 3.4 kg, 11.4 W, 12° FoV instrument that will measure the 1-10 keV X-rays from Mercury arising as fluorescent emissions during the impact by solar gamma rays and hard X-rays. Three gas-filled detectors will look to the planet while a solid-state detector will look sunward. It will enable inference of the composition of the surface elements. Richard Starr (GSFC/NASA) is the Lead Scientist. MAG (MAGnetometer) is a 4.4 kg, 4.2 W instrument mounted at the end of a 3.6 m boom that will map Mercury’s magnetic field and search for magnetized rocks in the crust. Brian Anderson (APL/JHU) is the Lead Scientist. MLA (Mercury Laser Altimeter) is 7.4 kg, 38.6 W infrared (1,064 nm) laser instrument that will enable accurate micro-topography of the surface. It will emit and receive eight pulses per second, enabling range measurement at an accuracy of 20 cm. David Smith (GSFC/NASA) is the Lead Scientist. MASCS (Mercury Atmospheric and Surface Composition Spectrometer) is a 3.1 kg, 8.2 W instrument that is sensitive to a wide band of wavelengths from infrared to ultraviolet and will map the atmospheric composition of atoms and molecules. William McClintock (U. Colorado, Boulder) is the Lead Scientist. EPPS (Energetic Particle and Plasma Spectrometer) is 3.1 kg, 7.8 W instrument that will monitor the energetic particles and plasma in Mercury’s magnetosphere. It is actually a two-instrument package: Energetic Particle Spectrometer (EPS) and Fast Imaging Plasma Spectrometer (FIPS). They both use time-of-flight detectors and energy detectors to obtain species counts and energies. Barry Mauk (APL/JHU) is the Lead Scientist. RS (Radio Science) will extract the doppler shift in the spacecraft telemetry signals accurately enough to infer the gravitational anomalies over Mercury, arising from crustal thickness variations. David Smith (GSFC/NASA) is the Lead Scientist.

C. Spacecraft Particularly Suited for International Participation

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.
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)

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.

The latest addition to the fleet is Navstar 54, 2004-009A.
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
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 last appeared in SPX-545. It
will not be repeated in view of the excellent updated source at:
http://www.glonass-center.ru/frame.html
maintained by the Coordinational Scientific Information Center (CSIC), Russian
Space Forces.
