Astronauts Say Teary Farewell, Seal the Hatches

The crew of the space shuttle and station said a teary farewell, then sealed the hatches between them Sunday after more than a week of working tirelessly together to build a bigger and better scientific outpost in orbit. Atlantis was scheduled to undock early today, its load considerably lighter than when it arrived Feb. 9 with Europe's premiere space laboratory, Columbus.Astronaut Daniel Tani was especially emotional as he left the international space station, his home for the past four months. Before floating into Atlantis for his long overdue ride home, Tani paid tribute to his mother, Rose, who was killed in a car accident while he was in space. He couldn't wait to get back to his wife and his two little girls.
