B. Text of Launch Announcements.

2007-052A,   2007-052B,   2007-052C
Cosmos 2431, Cosmos 2432, and Cosmos 2433 are the latest craft to join the Russian Glonass fleet of navigational satellites. They were launched by a Proton-K rocket from Baikonur at 7:35 UT on 26 October 2007. The launch had been delayed until Kazakhstan lifted the ban on Proton launches after the explosion of a Proton-M (on 06 September) spilled 219 tonnes of toxic heptyl fuel. The Glonass fleet will be completed in 2008, expanded to 24 satellites from the current 13, to become fully operational at all hours of the day. The initial orbital parameters of all three were period 675.7 min, apogee 1,935 km, perigee 1,925 km, and inclination 64.9°.
2007-051A
Chang'e 1 (named after a Chinese goddess who flew to the Moon) is a Chinese lunar orbit mission that was launched by a Long March 3A rocket on 24 October 2007 at 10:05 UT from Xichang launch center. It will enter the lunar orbit on 05 November 2007 after three Earth orbits with activated thrusters at each perigee. The 2.3 tonne (with fuel) craft carries a number of instruments:
Stereo Camera and Spectrometer Imager. Its resolution is 160 m, at the wavelength band of 0.48-0.96 microns.
Laser Altimeter. It is to operate at 1,064 nm outputting pulses of 150 micro-Joule, and will provide altitudes at 1.0 m accuracy.
Gamma and X-ray Spectrometer. The energy ranges are 0.3-9.0 MeV, and 0.5-50 keV
Microwave Radiometer. It will operate at 3.0, 7.8, 19.35 and 37 GHz sensing the soil at less than 1.0 m depth, at a temperature resolution of 0.5 K
High Energy Particle Detector and Solar Wind Detectors. It is capable of monitoring incident solar wind, and electrons and ions up to 700 MeV.
Full details of the mission is available at http://210.82.31.82/index.asp?modelname=eng\en-news. The instruments will enable the determination of the mineral content of the surface by means of the identified 14 atomic elements. The circular lunar orbit will be at an altitude of 200 km, and inclined from lunar equator by 64°. The orbital period will be 127 min. Wu Ji of the Chinese Academy of Sciences (CAS), and Ouyang Ziyuan of the China National Space Administration (CNSA) are among the chief scientists in the mission.
2007-050A
STS 120 is an American shuttle satellite that was launched from Cape Canaveral at 15:38 UT on 23 October 2007, on its way to the International Space Station (ISS). It carried seven astronauts (six Americans and an Italian) and several tonnes of material to the station. It docked with the ISS on 25 October. In the first spacewalk on 26 October, two astronauts moved and installed an Italian-built, 4.4 m diameter, 7.2 m long, 14.3 tonne aluminum tubular module named Harmony to facilitate connecting, in future missions, the European Columbus laboratory in December 2007, and the Japanese Kibo laboratory in February and April of 2008. Harmony will be the passage corridor between the American Destiny labs and these future labs. On the second spacewalk, two astronauts moved a pre-installed massive truss to a different location. The truss work continued on the third spacewalk, when it was noticed that there was a 90 cm long tear on the solar panel. Additionally, the rotary joint that aims another solar panel to the Sun was also discovered to be in need of repair/replacement. The fourth four-hour long spacewalk by a single astronaut on 03 November was confined to successfully repairing the torn solar panel with "cuff links", and ensuring full power availability. The rotary joint problem was deferred until the next shuttle mission. The contemplated additional inspection of the shuttle tiles was also determined to be ignorable. The shuttle is scheduled to leave the station on 05 November 2007, returning to Earth by 07 November.
The initial orbital parameters were period 91.4 min, apogee 344 km, perigee 340 km, and inclination 51.6°.
2007-049A
Cosmos-Oko, also known as Cosmos 2430, is a Russian military satellite that was launched by a Molniya-M rocket from Plesetsk at 04:39 UT on 23 October 2007. It is part of a fleet to detect rocket launches by infrared light. The initial orbital parameters were period 704 min, apogee 39,170 km, perigee 522 km, and inclination 62.8°.
2007-048A,   2007-048B,   2007-048C,   2007-048D
Globalstar-A, Globalstar-B, Globalstar-C, and Globalstar-D are the latest to join the American Globalstar fleet. They were launched by a Soyuz rocket from Baikonur at 20:12 UT on 20 October 2007.
The launch completes the first generation fleet of 40 satellites, with further additions from second generation models. The fleet of craft, each of mass 420 kg, services mobile telephones and fixed point transmitters carrying voice and data transmissions, by an array of C-band transponders and mediated by dedicated ground stations. The latest four craft are tentatively subscripted as -A, -B, -C, and -D, pending the assignment of formal names. The initial orbital parameters of all four were similar: period 103.47 min, apogee 930 km, perigee 914 km, and inclination 51.98°.
2007-047A
GPS 2R-17, also known as Navstar 60 and as USA 196, is the latest addition to the American fleet of navigational satellites. It was launched by a Delta 2 rocket from Cape Canaveral at 12:23 UT on 17 October 2007. It will replace the aging GPS 2A-14 in Plane F and Slot 2. The initial orbital parameters were period 356.6 min, apogee 20,369 km, perigee 192 km, and inclination 40°.
2007-046A
WGS F1 (Wideband Global SATCOM F1, also known as USA 195) is an American geostationary military communications spacecraft. It was launched by an Atlas 5 rocket from Cape Canaveral at 00:22 UT on 11 October 2007.
2007-045A
Soyuz TMA-11 is a Russian passenger transport craft that was launched by a Soyuz-FG rocket from Baikonur at 13:22 UT on 10 October 2007. It carried three astronauts (a Russian, an American and a Malaysian) toward the International Space Station (ISS). It docked with the ISS (Zarya module) at 14:50 UT, on 12 October 2007 and the astronauts joined their colleagues already on-board the ISS. The initial orbital parameters were period 91.4 min, apogee 344 km, perigee 340 km, and inclination 51.64°.
2007-044B
Intelsat 11 (also known as PAS 11) of the Bermuda-based company is a geostationary communications satellite that was launched by an Ariane 5 rocket at 22:02 UT on 05 October 2007. It carries 25 C-band and 18 Ku-band transponders to provide direct-to-home (DTH) voice and video transmissions in Latin America, after parking over 317° E longitude. It will be phased-in to eventually replace Intelsat's 6B and 3R satellites.
2007-044A
Optus D2 is an Australian geostationary communications satellite that was launched by an Ariane 5 rocket from Kourou at 22:02 UT on 05 October 2007.

The standard format of the GPS situation appeared in SPACEWARN Bulletin No. 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 60, 2007-047A.

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 SPACEWARN Bulletin No. 545. It will not be repeated in view of the excellent updated source at: http://www.glonass-ianc.rsa.ru/ maintained by the Information-Analytical Center (IAC), Russian Space Agency.

According to CSIC the latest additions to the fleet are 2007-052A, 2007-052B, and 2007-052C.
