Q&A with Curt Blake, president of Spaceflight Industries (members only)

The Starlink 6-66 mission comes near the end of a week during which SpaceX launched three Falcon 9 rockets in less than 20 hours and a Starship rocket. Liftoff from pad 40 at Cape Canaveral Space Force Station is set for 11:07 a.m. EST (1607 UTC).

SpaceX’s Falcon 9 rocket will go from the Kennedy Space Center to low Earth orbit in 10 minutes Saturday with a Dragon capsule heading for the International Space Station carrying nearly 5,500 pounds of supplies and experiments.

An official weather outlook issued by U.S. Air Force meteorologists Thursday calls for partly cloudy skies on Florida’s Space Coast for liftoff of a SpaceX Falcon 9 rocket just after sunrise Sunday with a clandestine payload for the U.S. government’s intelligence agencies.
