The countdown for a Saturday afternoon launch of the shuttle Discovery began today around noon our time. The Kibo laboratory has been closed out on the pad and is ready to go. The crew arrived at the Kennedy Space Center today to begin final preparations for the countdown.

I watched the mission brief this afternoon, and learned that Kibo is the largest object ever lofted by the Shuttle, but it is not the heaviest. Launches to the ISS are limited in the weight they can carry because of the steep inclination that is needed to get to the station. Earlier missions (not to the space station) have lofted satellites that are heavier than Kibo, and the main truss assembly for the station weighed more, though it was not as large.

Parts needed to repair the toilet in the Russian section of the station are being flown to the cape in a diplomatic pouch from Russia, and will be loaded onboard the mid-deck of the shuttle sometime tomorrow. Apparently one of the pumps that operates the toilet is kaput, and considering what the Russians consider to be a balanced diet, you can see why this is an immediate problem. Weight and center of gravity balance are critical on any mission, and Kibo is affecting the COG on this launch, so some 35 pounds of non-critical spares were offloaded to make room for the needed repair parts.

Launch is scheduled for 3:02 PDT on this Saturday afternoon. The weather is expected to be clear, so the video from the launch ought to be particularly spectacular.

It's launch day and the weather at the Cape looks pretty good this morning, and is expected to only improve as launch time approaches.

There isn't much happening at the pad right now, but they will commence tanking soon.

We have about 8 hours to go before the first launch window opens....

Does that mean "getting tanked" comes with a new meaning? :-)

We just entered the T-Minus 9 minute hold, and there is about 58 Minutes remaining until launch. Right now there are no contraints to launch, and the weather in Florida is clear.

Looking good!

OBTW, today marks the first time NASA has ever broadcast a launch in High Definition, so the ascent videos ought to be really something...

Truly, the Greatest Show on Earth! Spectacular launch, and it was so clear that you could see the entire Florida peninsula fade into the distance behind the shuttle as it launched...

Someone loved a spectacular launch? Sounds like another Florida vacation to view another launch before they finally stop launching the STS program?

I'd rather follow it on TV, especially since they have transitioned to High Definition. Any good digital ready TV will benefit from Hi-Def transmissions, and you really need to watch the ascent video replay to see what I mean.

The crew also has new HiDef hand held cameras, and are sending back a lot more crew video than earlier missions. This should be a fun and very interesting mission.

to back up a step, yesterday during the crew manup of Discovery, the NASA channel had an off-duty member of one of the backup closeout crew (the white room) narrating the live video, and explained everything that was going on, all in hi-def of course. It was fascinating to listen to, and I didn't realize how much work it took them to close, secure, seal and test the crew hatch...

This is great stuff...

I've heard some of this content on FVTV and over nasa's web site.. Your correct, its really cool!
