| Nasa has pushed back by a year its internal target date for flying the successor to the shuttle. Agency officials say they are now aiming for September 2014 for the first crewed mission of the Orion ship. This is a year later than Nasa had hoped for, but still inside its March 2015 absolute deadline. The officials say the funds currently available to develop Orion and its Ares launch rocket mean the faster timeline is no longer tenable.
