Live coverage: SpaceX supply ship returns to Earth

SpaceX’s final planned Crew Dragon test flight before astronauts ride the commercial spaceship into orbit is scheduled for Saturday, when an unpiloted crew capsule will fire off the top of a Falcon 9 rocket shortly after launch from the Kennedy Space Center in Florida to test the craft’s in-flight emergency escape capability.

SpaceX launched twin satellites for NASA Wednesday that will study how the electrically-charged solar wind interacts with Earth’s magnetic field, creating constantly changing and occasionally dangerous “space weather” affecting satellites, electrical grids and other critical systems.

Curt Blake, president of Spaceflight Industries, spoke with Spaceflight Now’s Stephen Clark on Sept. 29 about the Seattle-based company’s purchase of a dedicated rideshare mission on a SpaceX Falcon 9 rocket, and various trends and strategies in play in the small satellite launch market.
