I have a question: where in the space shuttle is an APU power?
Firstly, for the third time I'm hoping someone can answer my question about "spreading" - sometimes MCC will call the orbiter to let the crew know that there will be a loss of comm due to this spreading. What is spreading in this context?

What is spreading in this context?At the time when I heard it, I remember thinking it was the plume obscuring the RF, but that doesn't make sense if it was going up through TDRSS. Maybe multipath? (I figured on the 3rd try, a non-RF guy was allowed to guess.)
Appreciate your research AnalogMan, in Reply 2106 above, but that's not what I'm referring to. It actually looks like steam, it comes out in pulses, there is a sound that accompanies it, and it's coming out right at the location where the outlets for the water spray boilers are on either side of the tail after the Orbiter has come to a stop at the SLF, but has yet to shut off its APUs. Venting from the water spray boilers is the only thing that makes sense. I just wanted to make sure that it wasn't APU, expended hypergol "exhaust", because these vents are very close to the water spray boiler vents. Not a big deal, it's just that this looks so incongruous ("locomotive breath") coming out of a relatively high-tech Orbiter.

I never really made the time, or was too busy to watch the landings until the I found this site (and the time) to watch the last two SLF landings, and the last one would have been STS-119. I recall that the NSF coverage on the landing day thread that someone made a comment on what a noisy beast she was exactly at the point that I'm describing. This isn't the only time I've seen it, but can't recall any specific missions. But my impression was that this was completely normal. Indeed, the PAO on NASA TV never made any mention of it, either.

Banjul, also no longer used, is Yundum International Airport. NASA built a dedicated building at each of those locations.
"negative Moron, select Banjul."
