Endeavour's final landing - some nice infrared video

The Confederate soldier was peculiar in that he was ever ready to fight, but never ready to submit to the routine duty and discipline of the camp or the march. The soldiers were determined to be soldiers after their own notions, and do their duty, for the love of it, as they thought best. Carlton McCarthy

Cool!

I think the last launch (Atlantis in July?) will be very historic, in a backwards sorta way.

Also, 2 notes after watching the video:

1) With all of the money NASA uses.....you think they'd be able to put up some stadium-brightness lights around the runway.
2) Thought the blinking yellow light on top of the shuttle at first was, well a light. Had no idea that it had bursts of flames after it landed...guess I've only really watched the day landings!

1. They probably don't want to blind the pilot (just my guess) - his eyes are coming out of the darkness

2. Yes that really shows up on the IR video - is that exhaust from an APU (auxiliary power unit)?

OK, at 2:03, it sure looked like flame in front of the vertical stabilizer. :hair:

Yes, I just looked it up - it is in fact APU exhaust and yes occasionally it ignites - no big deal.

Question: I was lucky enough to be staying in Titusville, FL, when STS-106 Atlantis landed and was glued to the NASA broadcast in my hotel room. I noticed after the landing that there were jets of what appeared to be steam spurting intermittently at the base of the tail after the landing. Is this normal and what is it? Sincerely Bryan McComb

Answer: The exhaust plumes from the auxiliary power units (APUs) exit the orbiter at the base of the tail (APU 1 and APU 2 on the port side, and APU 3 on the starboard). Occasionally the exhaust plumes can ignite (the plume is composed of hydrogen, ammonia, and nitrogen), as happened post-landing on STS-106. This poses no danger to the crew or the orbiter, but the flame is very impressive! The pulsing is caused by the method used to control the APU speed - the fuel is sent to the APU until it reaches a certain speed, then the fuel flow is cut off until a lower speed is reached, then repeats. The water spray boilers (WSBs), used to cool APU lube oil and the hydraulic fluid, also exhaust at the base of the tail. All three WSBs exhaust steam continuously (vs. pulsing) out the starboard side.
