GPS III launch scrubbed again -- this time for weather

A GPS III launch slated to fly from Cape Canaveral Air Force Station, FL, today has been canceled due to weather concerns at the launch site.

This is the third cancellation this week for the mission, which represents two significant firsts for the Air Force and the national security space launch community: the launch of the first Lockheed Martin-built GPS III satellite and the first time SpaceX and its Falcon 9 rocket will fly an NSS mission.

The first two launches were canceled due to an "out-of-family reading" from sensors on the launch vehicle.

Today's launch has not yet been rescheduled.
