(Newser) – NASA has scrapped tomorrow's tentative launch of space shuttle Endeavour, reports, saying that it needs more time to fix the broken auxiliary power unit that delayed the launch on Friday. "We're looking more toward the end of the week, maybe next weekend," says a NASA spokesman. "We won't know until tomorrow when our next launch opportunity is." The power unit is in a difficult-to-access section of the shuttle.
