The president will bring his wife, Michelle, and two daughters, Sasha and Malia, to the launch, now scheduled at 3:47 p.m. a week from Friday
Sources close to the discussion said several factors played into his decision to attend.

Rep. Gabrielle Giffords (D-Ariz.), severely wounded during an assassination attempt in January, also is planning to attend and watch her husband, Endeavour commander Mark Kelly, lead a crew of six into orbit. Supporters see the trip as a sign she is recovering from her gunshot wounds.
