This is so sad. Poor guy is stuck up in space.
Daniel M. Tani's 90-year-old mother died in an auto accident this week, but he has no way of getting home until late January. He must grieve from more than 200 miles away in orbit, aboard the international space station.
It's a heartbreaking situation no other American astronaut has experienced. And it's made all the more tragic by Tani's devotion to his mother, Rose, who raised him and his siblings alone in suburban Chicago after their father died when he was 4.
