Giffords back in Houston after shuttle delay

Posted: Updated:

Congresswoman Gabrielle Giffords is back in Houston after NASA delayed the launch of space shuttle endeavor for the second time.

Endeavour will stay on the launch pad at Kennedy Space Center for at least another week.
Calling it a "typical electronics failure" but that means several days of testing.

Saturday's crowds are gone, and the shuttle astronauts are already back home in Houston.
