Discovery successfully docked with the station late Monday. Less than three hours after docking the crew’s work schedule was interrupted to inspect Discovery’s left wing, after a sensor indicated an object may have struck the shuttle. NASA will decide if further inspection is needed Tuesday.
Also on Tuesday Christer Fuglesang and his crewmate Robert Curbeam will make the first of three space walks. They’ll be attaching a two ton aluminium truss segment expanding the station.
During two other space walks they will be rewiring and upgrading the station’s electrical system.
