The chugging sound is the APU chuffing flame, it's not quite visible but believe me, it's HOT and it it's there. Right up near the base of the rudder, above the OMS pods. At night you can see the flame chuffing out. It's normal. Usually you don't get the audio like in the one.
these babies dont have any engines..so they rely purely upon drag and gravity...the nose is pointed down to obtain terminal velocity and so controlling its decent down..as soon as they come down towards the runaway they pull up to cancel out the velocity to a point where there is a fine balance on the decent (angleing up as they come down)..
since the engines in planes slow down on landing, a parachute is used as a substitute.
I think the "chugging" sound is the remaining propellant discharging from one of the directional thrusters. The whining noise is the Auxiliary Power Unit's (APU) the shuttle has 3.
The sound you heard was the ammonia spray boilers venting. The reason it was so prominent this landing was the shuttle happened to come to a stop at the location where the NASA TV microphones were placed before landing.
I made the similar question on another video post of the Shuttle Endeavour's landing and someone did replied that it was the APU and the lights could be seen on the evening landings of Space Shuttle Atlantis. But the noise on the background was the one that called my attention, cause I have never heard that weird noise!
Can someone explain what is that noise that you hear after landing of Endeavour at 2:50? It was something that you hear and if you look the infra-red screen, there is like lights or smoke and I never heard that on a Space Shuttle.

Next thing you know were landing a freckin spaceship. -___-

20 times steeper decent than a commercial airliner, wow!!

I was at cape kennady when it landed

That was a great clip, I didn't realise the descent rate and glide path was so high compared to a commercial aircraft.
What was that "chugging" sound at the end of the clip ? It sounded like a steam train.

I as well would like to know what that noise is. I've heard it at previous landings too. Some kind of APU or something?

APU exhausts, surely?

So what exactly do the ammonia spray boilers do?

saw it live and it is great to have the chance now to look at that excellent landing performed by commander Scott Kelly again!
