Ignition and liftoff! SpaceX’s Falcon 9 rocket and uncrewed Dragon spacecraft are climbing away from Kennedy Space Center’s Launch Complex 39A, beginning the company’s 25th resupply services mission to the International Space Station. Liftoff occurred right on time at 8:44 p.m. EDT.
Dragon will deliver more than 5,800 pounds of cargo to the orbiting laboratory, and its arrival is planned for Saturday, July 16. Coming up in the next minute, SpaceX’s Falcon 9 will pass through Max Q – the moment of peak mechanical stress on the rocket. After this, the rocket’s first and second stages will separate.
