I agree that this should point to the whole video, no to the last secconsds.

I prefer a variation of the submitted title:

"Space Station astronauts put GoPro camera into a floating ball of water in space"

The interesting part is that they put a camera there.

A slightly unrelated question about English usage: How do you call this rounded floating thing? It's a water bubble or a water drop?

I would not call it a "bubble" - to me that implies air surrounded by water. I would call it a "drop" or a "blob". However, as I've learned to my cost in another thread, not everyone agrees with me about the usage of language. Since it's got water in it, and it's big and round, some people will call it a "bubble."
