Gabrielle Giffords' husband Mark Kelly to lead space mission
The husband of wounded US congresswoman Gabrielle Giffords has said he has decided to resume astronaut training to command the final flight of the space shuttle Endeavour in April.
Mark Kelly has been on leave since his wife was shot in the head by a gunman in Arizona nearly a month ago.
He said he made the decision to return to his career because his wife's condition had improved "very fast".
