Here’s an interesting quandary: Mark Kelly, the astronaut husband of Congresswoman Gabrielle Giffords, can go into space in April as the commander of the final flight of the space shuttle Endeavour, which would last “at least a few weeks.” (Kelly has been to space three times before, most recently in June of 2008.) Or, he could stay by the side of his recuperating wife. On the one hand, his wife is struggling to recover after getting shot in the head. On the other hand … it’s space! It’s not like he has a hunting trip with his buddies that he planned months in advance. It’s space! Thoughts?
