Ridiculous claim. What do you think they make oxygen masks out of?

Oh, don't be stupid. Nitrogen is 2.7% of the Martian atmosphere.
There are also minerals that are over 25% nitrogen by weight.

That was only because they were doing a ground test, which meant they
had pure oxygen at over 15 PSI. Pure oxygen was used for Mercury,
Gemini, and Apollo, both before and after the Apollo 1 fire.
and try to keep up, learn some actual facts.

Almost any silicate, for example. Lots of silicates on Mars.

But there are apparently large piles of bat shit between your ears.
