Live coverage: SpaceX’s Falcon 9 rocket lifts off, then lands at Cape Canaveral

SpaceX launched a classified payload for the National Reconnaissance Office on Monday after a first stage sensor problem halted a countdown Sunday. Liftoff from launch pad 39A at NASA’s Kennedy Space Center in Florida occurred at 7:15 a.m. EDT (1115 GMT), and the first stage landed at nearby Cape Canaveral around nine minutes later. The upper stage’s flight entered a pre-planned news blackout a few minutes after launch.
