International Space Station programme managers decided to postpone the U.S. spacewalks planned for Aug. 21 and 29 until the fall to allow new Long Life Batteries to be delivered to the station aboard the SpaceX-4 commercial resupply services flight. A potential issue with a fuse within the battery of the US Spacesuits prompted the decision. The delay in completing the proposed spacewalks does not affect any daily operational capabilities of the station.
