U.S. President Barack Obama and his family left NASA’s Kennedy Space Center April 29 without seeing Space Shuttle Endeavour launch on what is to be its last mission. However, the first family proceeded with plans to tour shuttle facilities at Kennedy.
A problem with an auxiliary power unit aboard the orbiter forced NASA to scrub the launch less than four hours before Endeavour was scheduled to lift off on its 14-day mission to the international space station. NASA rescheduled the launch for no sooner than May 2.
Endeavour’s STS-134 mission is the second to last shuttle mission NASA plans to fly.
