Man On The Moon Revisited (Again!)

The debate whether man has set foot on Earth's only natural satellite rages on 39 years after the last flight of the Apollo space program in 1972. Many conspiracy theorists point out the 'irregularities' showing up in the photos but recently a forumner said that his own SCIENCE teacher is not convinced that Neil Armstrong et al has reached the moon. His reason?

"The moon's too hot...even hotter than the volcano (lava that is)...At night its too cold...colder than the Poles (North and South Poles that is, not people from Poland!) so that engines and equipment  are unable to function"

And also "Combustion needs oxygen....how can the engines fire when there is no oxygen on the moon?"

Bear in mind that it was a SCIENCE teacher who said that.....

As a note:

1. The moon (or indeed, the space) is very hot during the 'day'...but not as hot as lava. Average 'day' temperature on the moon is 117 degrees Celcius whilst lava is anywhere from 700 to 1,200 degrees Celcius. At 'night', it is indeed colder than the Poles with an average of -203 degrees Celcius.

2. That range of temperature exists not only on the moon but also just outside our atmosphere where there were hundreds (if not thousands) of satellite operating perfectly since Sputnik in 1957.....

3. About the last point, has the teacher never heard of liquid oxygen?
