Three astronauts from ISS landed safely in Kazakhstan this morning. Meanwhile, the next crew contingent passed its exams in Russia.
The space war continues. Lockheed is now planning a test flight of Orion capsule in 2013. The flight would occur, not on an Ares rocket, but on a Delta IV Heavy. More here.
Specifics of the proposed test flight haven’t been reported before. But those plans may run into flak as Republican lawmakers take control of House committees and subcommittees that oversee NASA, according to industry officials, including competitors, critical of Lockheed Martin’s efforts.
At least some of the incoming Republican panel chairmen and other senior GOP lawmakers, these officials said, may view the proposed test flight as circumventing congressional language to quickly develop a new heavy-lift NASA rocket able to transport astronauts past low-earth orbit. Congress has adopted language strongly favoring space-shuttle derived rockets for this purpose, rather than a version of the Delta IV. The Delta IV is operated by a joint venture between Lockheed Martin and Boeing Co.

Discovery’s launch delayed until December 17 at the earliest. Key quote:
Shannon said that one of the concerns was that another major crack might liberate a piece of insulating foam large enough to damage Discovery, as happened during the January 2003 liftoff of Columbia. A suitcase-sized chunk of foam punched a hole in Columbia’s wing, dooming the ship and her crew of seven astronauts when they reentered the atmosphere.
Shannon said that teams were also examining the possibility that the tanks have been flying with undetected cracks for years.
Cracks became more common after the 1998 debut of “super-lightweight” tanks built with a more brittle aluminum-lithium alloy. Since then, 29 cracks in stringers making up the ribbed “intertank” section that separates liquid hydrogen and oxygen tanks have been found and repaired in 18 tanks, including Discovery’s and a tank scheduled for use by the shuttle Atlantis next summer.

This week the Russians will give “final exams” to the main and backup crews for the next expedition to ISS.
Though NASA constantly rates its astronauts, it does not give them “exams.” This whole procedure (as well as how this Russian article is written) gives a nice flavor of the cultural differences between the U.S. and Russia.

NASA managers have once again delayed the launch of Discovery, now set for no earlier than December 3.
Almost literally, the probe Deep Impact flew through a snowstorm when it flew past Comet Hartley 2 on November 4. Below is one of the best pictures from the moment. More images can be found here. Key quote:
[The images] revealed a cometary snow storm created by carbon dioxide jets spewing out tons of golf-ball to basketball-sized fluffy ice particles from the peanut-shaped comet’s rocky ends. At the same time, a different process was causing water vapor to escape from the comet’s smooth mid-section. This information sheds new light on the nature of comets and even planets.
Note that all the close-up images taken by Deep Impact are going to be slightly out of focus, as the camera was launched with a defect.
NASA management is reviewing the “flight rationale” for Discovery’s next mission, considering the cracks in the external tank. Key quote:
Troubleshooters are assessing the structural integrity of the tank and its foam insulation to develop the necessary flight rationale, or justification, for proceeding with another launch as early as Nov. 30.

DARPA has completed its investigation on why a hypersonic test vehicle (HTV), launched on April 22, disappeared about 9 minutes into its flight. Key quote: “The HTV wobbled too much. Rather than risking an out-of-control flight, the bot self-destructed.”

A fourth crack has been found on Discovery’s external tank. How this will affect Discovery’s November 30 launch remains unknown. There will a briefing on Monday to discuss the status of the schedule. This quote however gives me the willies:
External tank crack repairs are not unusual. Some 29 stringer cracks were found in 18 previous tanks, according to an official familiar with their history. Four have now been found in Discovery’s tank, ET-137, and three were found in a tank scheduled for use by the shuttle Atlantis next summer, ET-138. Doublers were used in 23 repairs.
There is a saying that we always fight the last war. After the Challenger accident NASA made great effort to prevent another o-ring failure in the solid rocket boosters, and ignored the foam falling from the external tank. After the Columbia accident, NASA then made great effort to prevent another piece of foam from hitting an orbiter.
Unfortunately, it appears that NASA may now be ignoring this crack problem. Even though they have been able to repair past cracks, for this many cracks to occur this often should cause alarm bells to ring throughout the agency, forcing a look at the problem in toto. Instead, it appears management has been making catch-as-catch-can repairs.
What makes this situation even more difficult is the factory that makes the external tanks has shut down. No new tanks are available. Thus, there are not many options for flying these last few shuttle missions except by using the already existing tanks, and repairing them as needed.
Like I said, this is beginning to give me the willies.
Except for the failure to install a video camers, two Russian astronauts successfully completed a six hour spacewalk on ISS today, doing a variety of construction tasks on the station’s exterior.

This post by retired NASA engineer Wayne Hale explains why it probably is a good idea if Congress cuts the subsidies for new commercial space: The coming train wreck for commercial human spaceflight. This is the key quote, where Hale describes the regulations NASA is requiring these new companies to meet:
The document runs a mind-numbing 260 pages of densely spaced requirements. Most disappointing, on pages 7 to 11 is a table of 74 additional requirements documents which must be followed, in whole or in part. Taken all together, there are thousands of requirement statements referenced in this document. And for every one NASA will require a potential commercial space flight provider to document, prove, and verify with massive amounts of paperwork and/or electronic forms.
Is Spirit, the Mars rover, finally dead?
