Jonathan's Space Report No. 573 2006 Nov 18, Somerville, MA ------------------------------------------------------------------------------- Shuttle and Station -------------------- Progress M-58 was launched on Oct 23 carrying supplies for the Station. It soft-docked with the Zvezda module at 1429 UTC on Oct 26. However there were indications that the Kurs rendezvous orientation antenna mounted on the docking ring at the forward end of the Progress did not retract correctly. The Station remained in free drift for several hours; eventually it was decided that the antenna was fine, the latches between Progress and Zvezda were driven closed at around 1806 UTC, and the Station resumed active attitude control. STEREO ------ NASA's STEREO mission was launched on Oct 26 at 0052 UTC. The Delta entered a 165 x 171 km parking orbit at 0102 UTC; the second burn raised it to 166 x 3179 km x 28.49 deg at 0109 UTC. Stage 2 separated and the spinning stage 3 fired to place itself in a translunar orbit, planned prelaunch to be 182 x 403810 km x 28.5 deg. At 0117 UTC two despin weights were jettisoned and the STEREO A/B pair separated from the Star 48B stage. At 0119 UTC STEREO A and B were scheduled to separate from one another. They will remain in the translunar orbit several months and then use lunar gravity assists to enter solar orbit. The third stage was expected to reenter early on Nov 6; it was not cataloged. On Dec 15 at 1350 UTC STEREO B will pass 10745 km above the lunar surface and be thrown into a 130000 x 870000 km x 27.9 deg phasing orbit. Five minutes later, STEREO A will fly 5937 km above the Moon and enter a 180000 x 1750000 km x 33.6 deg orbit; ignoring the Sun's gravity, the instantaneous Keplerian orbit is formally bound (below escape velocity) but in fact STEREO A will escape the Earth-Moon system around Dec 24. On Jan 21 at 1552 UTC, STEREO B will re-encounter the Moon with a 16029 km altitude flyby and also end up on a departure orbit. STEREO A will end up in a 0.95 x 0.97 AU x 0.12 deg, 344 day orbit around the Sun, leading the Earth. STEREO B will end up in a 0.99 x 1.09 AU x 0.03 deg, 389 day orbit trailing the Earth. The two spacecraft will observe the Sun, allowing coordinated observations of solar activity from vantage points inaccessible for Earth-orbiting spacecraft. Optical and UV imagers, radio burst monitors and particle detectors will provide space weather information and allow study of Earthbound coronal mass ejections from the side. Messenger --------- The Messenger probe, launched in 2004, made its first Venus flyby on Oct 24. It passed 2990 km from the surface of Venus at 0834 UTC on a hyperbolic trajectory with an inclination of 116 deg to the Venus equator and an eccentricity of 3.27. Before the flyby Messenger's orbit around the Sun was 0.60 x 1.05 AU inclined 2.6 deg to the ecliptic. Now it is 0.55 x 0.90 AU with an increased inclination of 8.1 deg.

It is the first of a new heavy Chinese communication satellite series, DFH-4, with a communications payload by Alcatel Alenia. Xinnuo-2 and the CZ-3B third stage were placed in a 186 x 35797 km x 28.7 deg geostationary transfer orbit. After the first burn of Sinosat-2's apogee motor its orbit was 3372 x 35827 km x 18.1 deg. It reached geosynchronous orbit at 92E on Nov 5. XM Radio-4 ---------- Boeing Sea Launch orbited another Zenit-3SL on Oct 30 (reaching initial parking orbit early on Oct 31). The rocket put a Boeing 702 class satellite for XM Satellite Radio into geostationary transfer orbit. XM Radio-4, or XM Blues, joins the company's existing fleet of three satellites (XM Rock, Roll and Rhythm). By Nov 13 Blues was in geosynchronous drift orbit over 111 deg W. DMSP ---- A Boeing Delta 4M launched a US Air Force weather satellite on Nov 4. The Defense Meteorological Satellite Program (DMSP) Block 5D-3 spacecraft S-17, which became F-17 (Flight 17) when assigned to a launch, reached an 846 x 850 km x 98.8 deg sun-synchronous orbit after a single burn of the Delta 4 second stage, and separated at 1411 UTC. The Delta 4M could have launched a much heavier satellite and the stage had a lot of fuel left over. This was meant to be used to nosedive the used rocket stage into the Pacific with impact at around 1550 UTC, leaving only the DMSP in orbit together with two instrument covers from the main OLS (Operational Linescan System) imager. Justin Ray of spaceflightnow.com confirms to me that the stage was indeed tracked to reentry. However, SpaceTrack has now cataloged a large number of debris objects in orbit; this debris appears to have been generated around the time of the Delta deorbit, suggesting some kind of problem during the firing. The payload appears to be operating correctly although NOAA reports indicate a safemode associated with software issues. In addition to the OLS, DMSP S-17 also carries a microwave imager-sounder, ultraviolet spectrometers, particle detectors, a magnetometer, and a laser threat warning sensor which will alert operators if the spacecraft is attacked with a laser. Mass of DMSP F-17 is probably about 1200 kg, slightly smaller than its civilian cousin NOAA 18. Both DMSP and NOAA satellites are now operated by the NOAA weather agency. Badr 4 ------ Arabsat 4B, also known as Badr 4, was launched from Baykonur on Nov 8 by a Proton-M with a Briz-M upper stage. Dry mass of the EADS-Astrium Eurostar 2000+ satellite is 1487 kg; fully fuelled it is 3304 kg. It provides Ku-band communications for the Arab League. The Proton reached a near-orbital -390 x 173 km x 51.5 deg trajectory; the Arabsat/Briz separated and at the end of the first Briz burn was in a low 173 x 174 km orbit. Briz made 4 burns and deployed Arabsat into a 3127 x 35802 km x 14.1 deg orbit. It reached a near-geosynchronous 35593 x 35782 km x 0.1 deg orbit on Nov 16. Erratum ----------- The Sep 25 GPS launch was SVN 52, not SVN 58. GPS 58 ------ GPS navigation spacecraft SVN 58, the 3rd of the IIRM type, was launched by a Boeing Delta 2 on Nov 17. Kosmos-2423 ----------- Russia's Don spy satellite, Kosmos-2423, was destroyed in orbit on Nov 17 at the end of its mission.
