Florida ? Thunderstorms raking NASA’s spaceport kept space shuttle Atlantis in orbit an extra day Friday, giving the crew unwanted downtime as they aimed for a landing the next day.

After passing up two opportunities to land Friday at Kennedy Space Center, Mission Control thanked the seven astronauts for their patience.

The astronauts — fresh off successful repairs of the Hubble Space Telescope’s sophisticated instruments — intended to spend part of their day off watching DVDs. But when they tried to play the movies, they found out that their laptops didn’t have the proper software.
