Technicians at NASA Kennedy Space Center\u2019s Launch Pad 39A in Florida continue testing various systems inside space shuttle Endeavour associated with a newly installed power distribution box, called a Load Control Assembly 2 (LCA-2). So far, all systems have checked out. Overnight, teams will retest power for Endeavour\u2019s reaction control system.<\/p>\n
Endeavour\u2019s no earlier than launch date remains May 10, but senior NASA managers will meet Friday to evaluate the progress of repairs and select a new launch date for the STS-134 mission to the International Space Station.<\/p>\n
Engineers have been doing forensic engineering testing on the failed LCA-2, which was removed from Endeavour on Tuesday. The LCA-2 feeds power to a variety of systems, including heaters on the fuel line for Endeavour\u2019s auxiliary power unit-1 (APU-1). APUs control the shuttle\u2019s hydraulic system. Teams are trying to determine what caused a circuit inside the power box to short out. <\/p>\n
