SpaceX engineers are at Cape Canaveral, Florida, this morning, gearing up to launch two communications satellites atop a Falcon 9 rocket. After boosting the satellites into orbit, the rocket will navigate back down to a floating platform at sea and, hopefully, land itself upright and undamaged. SpaceX has pulled off this impressive maneuver three times already—let’s see if the streak continues.
Liftoff is set for 10:29 a.m. ET.
