This happens because the air heats up so much due to friction that it forms into another state of matter called plasma

Can someone confirm this? I was told the plasma is caused by compression not by friction.

Yup, I think that's an oopsie by NSF.

Plasma's basically caused by heat right?

Probably more technically energy. Think you can make plasma with accelerators. But energy is heat anyway basically. Not that I want to make myself out to be an expert because I'm absolutely not. I don't really know.

This is the first time the human race has seen reentry plasma live from external cameras.

Presumably they mean only humans on the ground? Did/do the Shuttle/Soyuz/Dragon have external cams viewable by the astronauts?
