The Antares was raised upright in anticipation of a launch later today, 19-Dec. However due to the cooling control valve problem on the space station the launch was postponed until mid-January.

We sort of knew the delay was coming, so it’s not a big surprise. As for the cooling valve, the fix will be accomplished by a series of spacewalks by (NASA) astronauts Rick Mastracchio and Mike Hopkins to replace the pump module.

The spacewalks will occur on December 21, 23 and 25. The replacement pump module is one they have “on the shelf” on the external stowage platform. The offending control valve is mounted on this pump module in case you were wondering.

I hope to be watching as coverage is going to be on NASA-TV and a link here if one is available and usually NASA is very good about such things. I am very interested in how the pump module is interfaced, always open to new ideas you see. The spacewalks are going to take six and a half hours EACH. Wow! Hope the suits work well and there is not water in the helmet issues. TV coverage (and hence the linked video) will begin at 06:15 EST / 11:15 UTC.

As for the raised Antares rocket, they will lower it and put it in “storage” out of the elements.
