Looks like we are ready to rock and roll
CAPE CANAVERAL, Fla. – The seven STS-123 astronauts have arrived at Pad 39A where shuttle Endeavour awaits a 2:28:12 a.m. EDT (0628:12 GMT) liftoff. The astronauts will enter Endeavour one by one, beginning with veteran shuttle commander Dominic 'Dom' Gorie, to prepare for this evening’s launch. The launch team is not working any technical issues and the countdown so far has been smooth and uneventful. |

The exhaust from the APUs is essentially invisible in normal light, that's why you never notice it on images of daytime landings. But it's a very hot exhaust, so it shows up like a whale's plume on the IR cameras they use for night landings.
I have to remind myself that this is the first night Shuttle landing in more than five years... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

QUOTE (dvandorn @ Mar 26 2008, 11:03 PM)  I have to remind myself that this is the first night Shuttle landing in more than five years... STS-115 was the last night landing in Sept 06; STS-114 the Return to Flight also landed at night. Although it was normal, most longtime observers are saying they haven't seen it this pronounced in a long time. One said that STS-51 was about the same. -------------------- |

QUOTE (BPCooper @ Mar 27 2008, 06:30 AM) Although it was normal, most longtime observers are saying they haven't seen it this pronounced in a long time. Huh. Maybe the APUs didn't consume as much fuel, or there was a higher then normal interior pressure in the tanks? Truth be told, hydrazine scares the hell out of me. F-16s use it for their starter mechanism, heard a lot of flightline urban legends/horror stories; nasty stuff, but guess that's true of all hypogolic fuels. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
