From: Jonathan's Space Report
Posted: Wednesday, March 16, 2011
Best wishes to my colleagues and readers in Japan. I understand that ISAS/Sagamihara is largely undamaged, but the ISS control center at JAXA/Tsukuba is out of action for the time being, thankfully with no casualties. I have not yet heard reports from the Kakuda hypersonic propulsion research center at Miyagi, near the epicenter.
I expect to be in Montreal on Apr 7 - do my Quebecois readers know if there are tours of CSA/St-Hubert?
Shuttle and Station
Soyuz TMA-01M undocked from the Station's Poisk module at 0427 UTC Mar 16. Crewmembers Aleksandr Kaleri (commander), Oleg Skripochka and Scott Kelly, formerly of Expedition 26, returned to Earth with landing in Kazakhstan at 0753 UTC. On the Station, Expedition 27 has now begun under the command of Dmitri Kondratev, together with flight engineer 5 Paolo Nespoli and flight engineer 6 Cady Coleman.
Space Shuttle Discovery was launched on Feb 25 on mission STS-133. Discovery's main cargo is Leonardo, the Permanent Multipurpose Module (PMM), a cargo storage unit now added to the station.
Discovery docked with the Station at 1914 UTC on Feb 26. On Feb 27 the Express Logistics Carrier 4 (ELC-4) was transferred from the Shuttle to the S3 segment of the stationt russ. ELC-4 carries spare parts for station external systems. On Feb 28 astronauts Bowen and Drew made a spacewalk from the Quest airlock to install a power cable between the Unity and Tranquility modules and move the failed Pump Module S/N 0002 from the mobile base system (where it was stashed during a previous spacewalk) to a longer term home on the ELC-2 carrier, freeing up the MBS attachment point to be used for other things. They also adjusted the track system for the Mobile Transporter so that it can move the robot arm down further along the S3 segment than before. The airlock was depressurized at 1541 UTC and repressurized at 2220 UTC; hatch open/close was 1546 to 2215 UTC.
The Station's SSRMS arm was used to move Leonardo from Discovery's cargo bay to the nadir port on the Unity module between 1346 and 1505 UTC on Mar 1.
On Mar 2 Drew and Bowen again used Quest to go outside, depressurizing it at 1535 UTC, and opening the hatch at 1541 UTC. Among other tasks they vented the failed Pump Module, retreived the LWAPA experiment support plate from Columbus and stowed it in the Shuttle payload bay, installed a camera on the Dextre arm, adjusted a camera sunshade and added a lighting system on the truss, and relocated the Strela adapter to the Zarya module from PMA3, where it had been stowed since 2006; the adapter was launched on STS-96 in 1999.
Discovery undocked from the PMA-2 adapter on the Harmony module at 1200 UTC on Mar 7, reducing the station's crew complement from 12 to 6. The spaceship made its 39th and final landing on runway 15 of Kennedy Space Center at 1657 UTC on Mar 9.
The Johannes Kepler ATV is docked at the Zvezda module; Kounotori-2 is berthed at Harmony nadir (on Mar 10, after the departure of Discovery, the SSRMS arm moved it there from Harmony zenith); Progress M-09M is at the Pirs module; and Soyuz TMA-20 at Rassvet. Launch of Soyuz TMA-21 has been delayed until April.
Taurus XL launch failure
The Orbital Sciences Taurus rocket suffered its second launch failure in a row on Mar 4. Once again the fairing failed to separate, and the extra mass being carried by the rocket meant that after stage 4 burnout the velocity was a few tenths of a km/s too low, giving the payload the correct orbital apogee but a negative perigee with impact probably in the Antarctic.
Orbital says that they used a different fairing separation system on this flight, one that has flown successfully in the past year on the Minotaur rocket, but the similar nature of the failure to the one that destroyed the Orbiting Carbon Observatory mission on the previous launch will inevitably be a blow to the company's reputation. The T8 failure was thought to be due to the failure of the separation system to pressurize; on this T9 flight, the system did pressurize but the fairing still did not separate. It may turn out that the pressurization issue wasn't the true cause of the T8 problem either.
The main instrument on NASA's Glory satellite lost in the Taurus flight 9 failure was an aerosol polarimetry sensor (APS) that would have provided a global map of aerosol particulates (soot and sulphates) which would have helped calibrate climate change models. This compounds the loss of OCO on Taurus flight 8, which would have made a global map of carbon dioxide. Even if a replacement APS is built, the delay of several years in these projects seems to me to be a significant blow to climate change research - in contrast to my own field of astronomy, a few years delay in improving our understanding of climate change may really matter to the world. Glory also carried a radiometer to measure the total solar output; this would have replaced the one that has been flying on the SORCE satellite since 2003.
Three cubesat payloads were also lost in the launch: Montana State University's Explorer 1 Prime, the University of Colorado's Hermes and the University of Kentucky's KySat-1.
