The uncrewed cargo Dragon spacecraft and Falcon 9 rocket are scheduled to lift off from Kennedy’s Launch Complex 39A in just about 30 minutes, at 11:17 a.m. EST. The mission will deliver more than 6,400 pounds of supplies, equipment, and critical materials to support dozens of science and research experiments that will take place during Expeditions 64 and 65.

About 12 minutes after today’s launch, Dragon will separate from the Falcon 9 rocket’s second stage, beginning a series of carefully choreographed thruster firings to reach the orbiting laboratory. Here’s a full look at today’s countdown and ascent milestones. All times are approximate:
