Space Shuttle Discovery landed safely today at the Johnson Space Center at Cape Canaveral, Florida after a 13-day, 5.3-million mile journey.

During this trip, which incidentally features two African Americans astronauts, Captain Robert Curbeam, USN, and Joan Higginbotham, the International Space Station was repaired, and also upgraded with new functionality.

In fact, Captain Curbeam performed a NASA single-mission four (4) extra-vehicular activity (EVA, or in popular parlance, spacewalks) tasks.

Welcome back.
