This GIF has been making rounds on Twitter for a few days already. I think if I had not searched Youtube for the video, I would not have seen any other version either. Among others, I'm quite certain that it was also shared by former NASA astronaut Mike Massimo [0] who has quite a few followers on Twitter [1]. (More people might know him from a (few?) cameo appearances in Big Bang theory though.) It is easy to have seen this on Twitter by now.
