The large billowing cloud that you see on US rocket launches is from the steam of the noise abatement system, its not from burning hydrogen. If you notice, the Shuttle only produces such a plume while its running its SRB’s, once it separates and goes to its Main Engines the smoke plume stops. Here is what is in the SRB propellant:

he propellant mixture in each SRB motor consists of ammonium perchlorate (oxidizer, 69.6% by weight), aluminum (fuel, 16%), iron oxide (a catalyst, 0.4%), a polymer (such as PBAN or HTPB, serving as a binder that holds the mixture together and acting as secondary fuel, 12.04%), and an epoxy curing agent (1.96%).[3][4] This propellant is commonly referred to asAmmonium Perchlorate Composite Propellant, or simply APCP. This mixture develops a specific impulse of 242 seconds at sea level or 268 seconds in a vacuum.

No hydrogen in the SRB's…

Liquid Hydrogen, along with Liquid Oxygen is contained in the External Tank, which in turn feeds the Shuttles Main Engines. There is little to no visible trail left after SRB sep, and ascent to orbit on the remaining Main Engines. You can clearly see the steam/smoke stop in this video immediately on separation:

Perhaps I am confused on where the water vapor actually comes from....

I've read things in the past that led me to believe that the exhaust was all (or mostly) water vapor, here is an example:

www.nasa.gov...


Exhaust from the main engines of NASA’s space shuttle, which is about 97 percent water vapor, can travel to the Arctic in the Earth’s thermosphere where it forms ice to create some of the Earth’s highest clouds that literally shine at night, according to a new study led by the Naval Research Laboratory and jointly funded by NASA and the Office of Naval Research.


So if the burning hydrogen doesn't create large plumes of vapor, why is NASA saying that 97% water vapor exhaust creates clouds? Your video does indeed show a lack of large exhaust plume, which has got me confused. What is NASA saying creates the clouds then?

The point he was making is that almost all of the 'cloud' you see in the OP is not from the burning fuel. It's from liquid water that was heated by the engine firing. If you think about the amount of steam that comes from your stove when you boil water, I think you can start to see that this amout of water vapor is rather insignificant.

The people being forced to move sucks I will admit (assuming its true as I didn't check), but you can seriously get hurt just from the noise if you're too close.

From the paper you linked:


About half of the water vapor exhaust from the shuttle’s main fuel tank is injected into the thermosphere, typically at altitudes of 64 to 71 miles

So they are talking about the thin clouds that are left behind by the Main Engines at high altitude creating Noctilucent Clouds, not the thick steam cloud left by the SRB Engines. To my knowledge the thick clouds created by the SRB are solely a result of the water used in the Noise Abatement System at launch. Again, in case you missed my first post, this is the Noise Abatement System being tested:

…And here again is a Russian Rocket with no Noise Abatement System:

Notice that the Russian rocket also does not leave the thick steam cloud that the shuttle leaves on initial take off.

Nothing to see here(non-sarcastic). I'm very open minded about a lot of the stuff on this site, but this is an ordinary thing that has been going on for a long time. Since there is nothing to hide, the government, in this case, doesn't. You can go visit Stennis Space Center and they will tell you everything you want to know. And in this case, it isn't just what they want you to know. Wow. Threads like this make me question questioning everything.

Alright I get it now, I was confused by the term "clouds" since I assumed they were talking about the large billowing ones at takeoff.

Thanks for setting me straight

this could provide an explanation for all of the loud "booms" everyone has been hearing... especially in wisconsin recently.
