Noguchi and the crew trained for this flight until February 2003, when STS-107, the flight immediately prior to STS-114, broke up while returning to Earth, destroying the Space Shuttle "Columbia" and killing the seven astronauts on board; following this all shuttle flights were delayed. Since STS-114 was scheduled to be the next mission to fly following STS-107, its designation and crew were assigned as the "return to flight" mission, their flight remained relatively similar although new tasked needed to verify the changes made to the shuttle and the shuttle flight plan were added to the flight. Also, the delay in shuttle flights meant the launch of Expedition 7 was moved from STS-114 to Soyuz TMA-2, leaving three more seats to be filled on STS-114, NASA astronauts Charles Camarda, Wendy Lawrence and Andrew Thomas were added to the crew to take their place.
