Jonathan's Space Report No. 660 2012 Jun 19 Somerville, MA USA -------------------------------------------------------------------------------- Space Station ------------- Expedition 31 continues with commander Oleg Kononeko, and astronauts FE-1 Gennadiy Padalka, FE-2 Sergey Revin, FE-3 Joe Acaba, FE-5 Andre Kuipers and FE-6 Don Pettit. Space station docking ports: Port Spacecraft --------------------- PMA-2 vacant PMA-3 vacant Zvezda Edoardo Amaldi (cargo) Pirs Progress M-15M (cargo) Poisk Soyuz TMA-04M (ferry) Rassvet Soyuz TMA-03M (ferry) Harmony vacant (was Dragon C2+,cargo) The mass of Dragon C2+ was probably around 6650 kg at launch. (Thanks to Bernd Leitenberger for useful pointers to Dragon masses). It's still not clear how much of this is the mass of the trunk versus the mass of the reentry capsule; my guess is around 500 to 1000 kg for the trunk and solar panels. Dragon C2+ was unberthed from Harmony at 0807 UTC May 31 by the station SSRMS arm, and released at 0949 UTC. The deorbit burn from 1451 UTC to 1501 UTC reduced the spacecraft's velocity by 100 m/s and lowered the orbit to around 62 x 392 km. The trunk separated at 1509 UTC and entry began at 1525 UTC. Splashdown at approximately 120N 27W in the Pacific occurred at 1542 UTC. Shenzhou 9 ---------- The Shenzhou 9 mission is a major step for the Chinese space program, featuring their first piloted docking. It's roughly comparable to a combination of the Gemini 8/Agena and Soyuz-11/Salyut-1 missions (but I hope it will end more successfuly than either of those flights). Tiangong-1 is smaller than the early Salyuts, and has caused some pedantic discussion about the definition of a space station (regular readers will appreciate that pedantic is not a derogatory term in my book :-)); In the spirit of my friends the Pluto-killers, I will count TG-1 as a 'dwarf space station'. Launch of China's Shenzhou 9 spacecraft took place on Jun 16. The crew is commanded by Brig. (daxiao) Jing Haipeng (who flew on SZ-7) and includes Brig. Liu Wang and Maj. (shaoxiao) Liu Yang. Major Liu is the first woman to fly in a Chinese space crew, and her launch as the 56th woman in space came on the 49th anniversary of the flight of Valentina Vladimirovna Tereshkova. (Note: the daxiao rank is sometimes translated 'Senior Col.' and is roughly equivalent to UK 'Brig.', but no direct US equivalent I think.) The Shenzhou program is managed by the Zhongguo zairen hangtian gongcheng bangonghsi (China Manned Space Engineering Office) which is part of the PLA's Zong Zhuangbei Bu (General Armaments Dept). At about 1440 UTC on Jun 17 the ship maneuvered from 261 x 315 km to 315 x 326 km. On June 18 at 0608 UTC the Shenzhou 9 spaceship docked with the Tiangong 1 spacelab. At 0910 UTC the three astronauts opened the TG-1 hatch and entered the lab for the first time. (The robot Shenzhou 8 ship had docked with TG-1, but this is the first visit with a crew). ZX-2A ----- On May 26 China launched a CZ-3B rocket from Xichang placing the ZX-2A (Zhongxing-2A, Chinastar-2A) spacecraft in a 207 x 35786 km x 27.1 deg geostationary transfer orbit. ZX-2A is believed to be a new generation strategic military communications satellite for the Zhonggou Renmin Jiefangjun (Chinese People's Liberation Army) and may have the classified name Shentong-2. On Jun 15 the spacecraft was in a 35780 x 35793 km x 0.2 deg geostationary orbtit over 98E, following an apogee burn sometime around May 30. YW-15 ----- On May 29 Yaogan Weixing shiwu hao ('Remote Sensing Satellite No. 15') was launched from Taiyuan space center by a three-stage CZ-4C into a 1201 x 1206 km x 100.1 deg sun-synchronous orbit with a 2:30pm local time descending node. The CZ-4C third stage made a depletion burn to lower its orbit to 966 x 1207 km. GRAIL ----- The two GRAIL spacecraft, Ebb and Flow, in a 25 x 86 km lunar orbit, completed their primary mission on May 29 and their science instruments were turned off until Aug 30, when they will begin a several-month extended mission in a 23-km altitude orbit. IS-19 ----- On Jun 1 Sea Launch flew a Zenit-3SL from the Odyssey launch platform on the equator, at 154W 0 N. The rocket's second stage flew to a -2174 x 188 km trajectory, followed by the first burn of the DM-SL third stage which reached a 180 x 1065 km x 0.0 deg parking orbit at 0536 UTC. After a second burn the payload was delivered to an 882 x 35804 km x 0.4 deg geostationary transfer orbit. On Jun 15 the spacecraft was in a 35665 x 35866 km x 0.2 deg orbit over 170.8E. Payload of the Zenit is Intelsat IS-19, a Loral 1300 type satellite with a C and Ku-band communications payload for Intelsat. One of the satellite's solar arrays was damaged during ascent, shortly after fairing separation, and investigation is still underway. NuStar ------ NASA's NuStar satellite was launched on Jun 13. It is the first X-ray astronomy satellite with optics able to focus `hard' X-rays (about 10-100 keV in general, 6-80 keV in this particular case); an extendable mast carries two optics modules, each 0.38m in diameter and focussing images onto 64 x 64 pixel CdZnTe detector arrays, with 40 arcsecond spatial resolution. The spacecraft will be particularly useful for studying obscured black holes (ones whose other radiation is absorbed by surrounding material) and the distribution of chemical elements in supernova remnants. The L-1011 airplane took off from Kwajalein at 1500 UTC and dropped the Pegasus at 1600:37 UTC over 167.70E 6.74N. The vehicle reached orbit at 1610 UTC, and NuStar separated from the third stage at 1613 UTC in a 627 x 633 km x 6.0 deg orbit. The equatorial orbit avoids the high particle background seen by polar orbit satellites. The NuStar optics module boom will be deployed on June 20 if all goes well. The 360 kg satellite is a small telescope, but the hard X-ray band is relatively little-explored. The major X-ray observatories - Chandra and XMM-Newton - work in the 0.5-10 keV `normal' X-ray range, and the gamma-ray observatories start paying attention around 100 keV and upwards. Suborbital launches ------------------- On Jun 7 a training launch of a Topol' missile from Kapustin Yar to Sary Shagan was widely observed from Armenia, Iran and other countries in the region. Several astronomy sounding rockets are at White Sands preparing for launch in the coming weeks. 2012 Orbital launch summary to date ----------------------------------- 33 launches: China 10, Russia 9, US 7, Europe 3, India 1, Japan 1, Iran 1, N Korea 1 (failed). I am counting Sea Launch as US, taking into account that the Blok DM-SL upper stage of the Sep 2011 AB-7 launch was registered with the United Nations by the United States.
