(NASA) – At 1:24 a.m. EDT, a smoke alarm sounded aboard the International Space Station’s Zvezda service module. Expedition 23 Commander Oleg Kotov quickly assessed that it was a false alarm that occurred while he was cleaning air filters in the module. The Expedition 23 and STS-131 crews are continuing their joint operations aboard the International Space Station.

STS-131 Mission Specialists Rick Mastracchio and Clayton Anderson wrapped up the first of three planned spacewalks at 7:58 a.m. EDT Friday. They configured an old Ammonia Tank Assembly (ATA) for removal and prepared a new ATA for installation. On the center-most portion of the station’s backbone, they replaced a Rate Gyro Assembly, part of the station’s navigation system. The spacewalk lasted six hours, 27 minutes.

The crews continue to unload the Leonardo Multi Purpose Logistics Module and transfer 17,000 pounds of science racks and other supplies into the station, a job that will take several days.

Anderson and Expedition 23 Flight Engineer Soichi Noguchi opened the hatch to the “moving van” at 7:58 a.m. Thursday. The module was relocated from Discovery’s payload bay to a port on the Harmony node at 12:24 a.m.

The Italian-built module’s more than 17,000 pounds of cargo includes four experiment racks along with the final private crew quarters. This is the final roundtrip to the station for the 21-foot-long, 15-foot-diameter Leonardo. Once back on Earth, the module will be reconfigured with increased shielding on the outside for the STS-133 mission in September when it will be left on the station as a permanent module.

STS-131 is the 33rd shuttle mission to the station.

Perfect job,unbeliveble skill reducing paylod at ISS-131 about (17,000)pounds and improving the property of velocity in the space shuttle,regenration of power,now changing of coolant ammonia tanks at satellites ISS-130,and cleaning simultanously filters for the effeciency of engines.SPACE SHUTTLE-STS-130-EVA-126-STS-127-STS-131 is well technically equiped from necessary work(exploration...)
