(AP Photo/John Raoux) NASA has scrapped tomorrow's tentative launch of space shuttle Endeavour, reports Space.com, 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. Read These Next Cuba paid dearly in the US strike on Venezuela. Formal dining rooms may soon be a thing of the past.
