When Chinese astronauts made their first spacewalk outside China’s new Space Station, Scott Parazynski watched, and it brought a smile to his face because they seemed to be having fun.

The retired NASA astronaut flew five times on NASA’s Space Shuttle and walked in space seven times primarily working on construction and repairs to the International Space Station.
