MOFFETT FIELD, Calif. — Weather permitting, San Francisco Bay Area residents will have a good opportunity to see space shuttle Discovery and the International Space Station pass overhead at approximately 7:25 p.m. PST on Tuesday, March 8.

The shuttle crew and station with the Expedition 26 crew aboard is nearly 220 miles above Earth’s surface. Together, they will look like a bright star in the twilight sky as they approach from the northwest, fly almost directly overhead and travel southeast.

Space enthusiasts may also track the current position of the station and other spacecraft orbiting Earth using the NASA App for the iPhone and iPod touch, as well as the NASA App HD on the iPad. The Apps also allow users to find and share current visible sighting opportunities for the station and shuttle. iPad, iPhone 3GS and 4 users also will see a working compass at the top of the screen to help locate the visible pass approach and departure path. Both Apps are available free of charge at the App Store from Apple.
