SpaceX has published an explanation for the debris from the Falcon 9 second stage that fell over Poland last week. Because of an oxygen leak, the expected deorbit burn didn't occur.

But the second stage failed to complete its second burn after a liquid oxygen leak. “Falcon 9’s second stage performed its first burn nominally, however, a liquid oxygen leak developed on the ...

For nearly a year, SpaceX has been trying out something new: super-cooling the liquid oxygen (LOX) which is a key ingredient in rocket fuel. It's called deep-cryo LOX, and the idea has been around ...
