Here is a story which does not answer one question.
"European Space Agency astronaut Thomas Pesquet, who has been aboard the International Space Station since November, posted photo to social media of two wedding rings floating in micro gravity.
The flight engineer from France tweeted that he carried in his personal items the wedding bands of two friends tying the knot this Summer."
The story link which is pretty much the same on every site which carried it is pretty much the same and has a photo of the two wedding rings floating in space. But as far as I can tell from the photo from the story, the rings are not tethered to anything so how does he get them back in?
In the journalistic world of who, what, where, why and how, the "how" is missing.
