Using a combination of robotics and spacewalking expertise, Discovery’s crew members installed a new Ammonia Tank Assembly (ATA) on the International Space Station’s Starboard 1 truss. Mission Control verified that electrical connections with the ATA are working. Because of a troublesome bolt, the spacewalkers fell behind the timeline and wer

On April 09, 2010 American astronauts Clayton Anderson and Richard Mastracchio performed the first of three planned spacewalks.
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.
On April 07, 2010 Space shuttle Discovery (STS-131 flight) docked with the International Space Station at 07:44 UTC.
Discovery delivered to the station new science racks and ammonia tanks. While there, two shuttle astronauts will perform three spacewalks to switch out ammonia tanks on the station.
