Way back in 2013 I naively asked a question on the Observation Deck about a member of that year’s astronaut class. This week she was one of three new crew members arriving at the International Space Station to begin Expedition 59 and I got a definitive answer to that question.

So yes, Christina Koch is wearing her glasses in space. As I found out NASA is okay with it and even veteran astronaut Mark Kelly wore glasses during his year in space.

But that image of Koch being greeted upon her arrival at the ISS raises another question. Why is she wearing what looks like two watches on her wrist?
