Live coverage: Dragon cargo craft arrives at space station

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.

A Falcon 9 rocket soars skyward from Cape Canaveral carrying NASA’s TESS observatory on a mission to discover planets around other stars. This was the view from the Kennedy Space Center Press Site.

The Falcon 9 first stage booster assigned to launch as soon as March on SpaceX’s first mission with a previously-flown rocket has been test-fired at the company’s development facility in Central Texas.
