Among with other STEM courses, a career with lucrative paychecks.
Were you able to even get a job in the fast food industry with YOUR degree ?

They DID, you just were not paying attention.

No, there is no such thing as you say, as HEAT energy can not be used to 
form ice.
Not even getting into the question of where the water to make the ice would 
come from.
You don't even know how ice sublimation works, and that it would not only 
have been impractical for use by apollo, but downright impossible.

Heat has to be disipated, and those packs had no venting or radiating 
ability whatsoever.
Especially in unrenting direct sunlight without even an atmoshpere to filter 
out any part of the radiation.

And speaking of cars,....even with air around one to disspate heat, a car 
sitting in the sun ON EARTH, gets awfully hot both inside and out.
Now imagine if there were no air around it to disspate even part of that 
heat. Paint would bubble. plastic would melt

You know nothing other than the NASA propaganda fairytales , and are not 
even worth further replies.
....Good day sir.
