ORLANDO, Fla. -- The next possible launch of the space shuttle Endeavour has been pushed back again, this time to no earlier than May 10.
NASA spokesman Kyle Herring said the mission management teams probably will wait until at least Friday before setting a firm launch date.
The teams met Monday and determined they will need most of this week to see if there are any problems left once they replace a faulty switchbox, probably late Tuesday. That trouble-shooting effort will take a minimum of two days.
The first launch attempt, on Friday, was scrubbed when NASA engineers found problems with a heating system that moderates temperatures of fuel lines controlling the shuttle's hydraulic systems. At first, NASA hoped to launch as early as Monday, then pushed that to next Sunday, and now to the following Tuesday.
