"Plan for your
future,
because that is where you are going
to spend the rest of your life."
Mark Twain
Now that's what I call rocket fuel!
The liquid hydrogen in the Space Shuttle
main engine is -423 degrees Fahrenheit
(-253 degrees Centigrade), the second
coldest liquid on Earth, and when burned
with liquid oxygen, the temperature in
the engine's combustion chamber reaches
+6,000 degrees F. (+3,316 degrees C.)
