SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Friday, heading due east over the Atlantic Ocean to deliver the JCSAT 14 communications satellite into orbit 32 minutes later.

Boeing engineers in New Mexico are readying a Starliner spacecraft for a critical pad abort test this fall to demonstrate the capsule’s ability to escape an emergency on the launch pad before green-lighting the capsule to carry astronauts.

A barge and command ship chartered by SpaceX are stationed in the Atlantic Ocean off Florida’s East Coast in a bid to recover a used-up Falcon 9 rocket stage Tuesday in a long-theorized — but never tried — maneuver that could lay the groundwork for a big advance in space technology.
