"It is sad to go to pieces like this but we all have to do it."
Mark Twain
Today, two astronauts conducted a seven hour twenty minute spacewalk in order to replace the wrist joints on the International Space Station's Canadarm 2. You have my sympathies, Canadarm - in my case, it's the knees that are showing signs of age, although I'm hoping to avoid any sort of similar replacement surgery.
