Mark Kelly is trending on news that he has decided to fly the space shuttle Endeavor on its upcoming mission in April. The astronaut-husband of wounded Arizona Congresswoman Gabrielle Giffords has been conflicted because commanding the space mission will mean leaving his wife’s side for weeks as she continues her rehabilitation from being shot in the head in early January. The Endeavor mission is the last planned flight for NASA’s space shuttle program and will be Kelly’s fourth and presumably final time in orbit.
