Awwal 23, 1432 / April 27, 2011, SPA -- Pioneering science and celebrity attention will give added lift on Friday to U.S. space shuttle Endeavour's final launch, in which the shuttle commander and his convalescent congresswoman wife will be in the spotlight, Reuters reported. President Barack Obama and his family will be at the Kennedy Space Center to watch Endeavour blast off at 3:47 p.m. EDT (1947 GMT) in what will be the second-to-last flight of space agency NASA's 30-year shuttle program, which is being phased out this year.
