-197°C, colder than BP of O2, so can use it to condense O2 out of air.
May also use it to cool the O2 tank before loading liquid O2 itself, also to precool the H2 tanks before loading Liquid H2.
Don't know for sure.

Used to use it in lab, a chem nubie had a leak in the vacuum setup and pulled air into the liquid N2 trap, condensed (made liquid) O2.
Liquid O2 is dangerous stuff if not handled with extreme care!
We drop the dewar off the trap and pulled the hood door down and went to lunch for 2 hours while the liquid O2 boiled off and was pulled out the vent stack.

Next try is for Friday around the same time 1:10am. If it doesn't launch Friday, then they'll try Satuday, but after that, it may be scrubbed all together.

Just saw it go up, it was AWESOME!

It started to turn and freaked me out a little, then the boosters fell off, it all happened pretty darn quick.

Very Cool!
