Video: Tower rollback prior to launch of Mars Pathfinder atop a Delta 2

The launch of a new U.S. weather satellite from Vandenberg Air Force Base in California has been delayed at least four days to Nov. 14, allowing time for technicians to remove and replace a faulty battery on the payload’s Delta 2 rocket, United Launch Alliance said Monday.

The U.S. Air Force on Thursday demolished towers once used to assemble Delta 2 rockets at Cape Canaveral for missions to Mars, four dozen flights to deploy the GPS navigation network, and numerous launches with scientific, commercial and military payloads.

After making landfall in South Florida, Hurricane Irma moved north over the state before losing strength and being downgraded to a tropical storm. NASA safety officials report the Kennedy Space Center lost electricity and water pressure during the storm, but a team of emergency personnel at the spaceport is safe.
