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.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Wednesday to begin a day-and-a-half pursuit of the International Space Station.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the GovSat 1 communications satellite into orbit around 32 minutes later.
