Space Shuttle Launch: WATCH IT LIVE

Posted: Updated:

The space shuttle Atlantis is set to blast off today at 2:01pm for its most dangerous mission ever: repairing the Hubble Telescope. The mission will require five risky spacewalks and NASA is so concerned that something may go awry that they have the space shuttle Endeavour and a second crew ready to go should an emergency rescue operation be necessary.

Watch the shuttle launch live below.
