| 2001-009A | USA 157 is an American geosynchronous military communications spacecraft that was launched by a Titan 4/Centaur combination from Cape Canaveral at 21:20 UT. The 4.5 tonne spacecraft is the first in the Milstar 2 series which is capable of higher data rates and is more secure against disabling efforts. |
|---|---|
| 2001-008A | Progress-M 44 is a Russian, automatic cargo carrier that was launched by a Soyuz-U booster from Baikonur at 08:09 UT. It carried 2.5 tonnes of food, water, fuel, oxygen, and equipment to dock with the Zvezda module of the International Space Station (ISS) which has been hosting the first crew of astronauts (two Russian and one American) since early November 2000. In preparation for the docking, that crew repositioned the Soyuz TM-31 escape craft from its port on Zvezda to a port on the Zarya module. It docked at 09:47 UT on 28 February. Initial orbital parameters were period 88.64,apogee 243 km, perigee 193 km, and inclination 51.6 deg. |
| 2001-007A | Odin is a Swedish dual disciplinary (astrophysics and atmospheric science) spacecraft that was launched by a START 1 rocket from Svobodny cosmodrome in far-eastern Siberia at 08:48 UT. (START 1 is a modified Topol ICBM.) The 250 kg, 340 W spacecraft has a pointing accuracy of 15 arcsec and a data storage capacity of 100 MB. It carries a cryogenic radiometer to monitor three millimeter-bands at 118.25-119.25, 486.1-503.9, and 541.0-580.4 GHz, at a resolution of 0.1-1.0 MHz. It carries also a cryogenic optical spectrometer to cover three visible and infrared bands at 280-800 nm, and another infrared band at 1,270 nm. The target gases of astrophysical interest are carbon iodide (CI), water vapor, hydrogen sulfide, ammonia and a few others. For atmospheric studies, the gases are chlorine monoxide, nitrous oxide, nitrogen dioxide, hydrogen peroxide, nitrous oxide, nitric acid, and a few others. Both instruments were fed by a 1.1 meter Gregorian telescope. Initial orbital parameters were period 97.6 min, apogee/perigee 622 km, and inclination 97.83 deg. |
| 2001-006B | Destiny is an American module on the ISS that was carried by STS 98 and fitted robotically to one of the ports on the Unity module of the ISS on 10 February. The 8.4 meter long and 4.2 meter wide cylindrical structure of mass 15 tonnes will function as a science and technology module as well as a primary control module for the ISS. |
| 2001-006A | STS 98 is an American shuttle spacecraft that was launched from Cape Canaveral at 23:13 UT. It carried a large module, Destiny, and a crew of five astronauts to deliver it to the International Space Station (ISS). It docked with the Unity module on 9 February, and delivered Destiny (2001-006B) to another port on Unity. After many hours of spacewalking, the astronauts secured the electrical connections and mechanical fittings. The crew also delivered over a tonne of food, fuel and equipment to the ISS. STS 98, with all five astronauts, landed at Edwards AFB in California on 20 February at 20:33 UT due to persistent wind problems at Cape Canaveral. Initial orbital parameters were period 92 min, apogee 378 km, perigee 365 km, and inclination 51.5 deg. |
| 2001-005B | Skynet 4F is a British geosynchronous military communications spacecraft that was launched by an Ariane 44L rocket from Kourou at 23:05 UT. The 1.5 tonne (with fuel) spacecraft carries a total of eight transponders in the SHF-, UHF-, and S-bands to provide secure communications after parking over either 1 deg-E or 6 deg-W. |
| 2001-005A | Sircal is an Italian geosynchronous military communications spacecraft that was launched by an Ariane 44L rocket from Kourou at 23:05 UT. The 1.25 tonne (dry mass), 3.3 kW, 3.4 m x 4.9 m, triaxially-stabilized spacecraft carries a total of nine transponders in the SHF-, UHF-, and EHF-bands to enable secure communications after parking over 16.2 deg-E longitude. [SHF: Superhigh Frequency. UHF: Ultrahigh Frequency. EHF: Extremely High Frequency. Band ranges are not available now.] |

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).
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.
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.

Note: Until about 1990, our Bulletins (or any other known to us) did not carry the names of rockets that launched Soviet spacecraft.
