Astronauts prepare for Endeavour's final flight

Navy Capt. Mark Kelly, the husband of wounded Congresswoman Gabrielle Giffords, and his five crewmates have arrived at NASA's Kennedy Space Center to begin the official countdown to the launch. The mission is the penultimate flight before the US space shuttle programme is wound up. 


Mr Kelly said he was looking forward to seeing his wife attend the shuttle launch. She has been in Houston, where she is undergoing rehabilitation for a gunshot wound to the head. She was attacked Jan. 8 in her Tucson, Arizona, hometown. 

"I'm personally looking forward to my wife, Congresswoman Gabrielle Giffords, getting here pretty soon, to be here in time for our launch on Friday," he told the crowd of family members and journalists.
