Live from launch pad 39A (members only)

SpaceX sent a cargo capsule with nearly 5,500 pounds of experiments and supplies on a three-day trip to the International Space Station on Sunday, firing the automated spaceship through low-hanging clouds and into orbit from the same launch pad where Apollo astronauts began voyages to the moon.

Following two Falcon 9 launches from both California and Florida, SpaceX closed out the first weekend of December with a Falcon Heavy static fire test. The ignition of the 27 Merlin engines comes a week ahead of the planned launch of the U.S. military’s secretive X-37B spaceplane.

Stymied by Russian government dithering that has indefinitely grounded a launch on a modified Soviet-era missile, Iridium officials say that SpaceX agreed to move up to July the first of seven Falcon 9 launches from California with the company’s next-generation mobile communications satellites.
