Shuttle Atlantis unwrapped ahead of public debut

SpaceX simulated an in-flight emergency Sunday to verify the company’s Crew Dragon spacecraft has the capability to catapult away from a failing Falcon 9 rocket.

A top secret payload developed in secrecy for the U.S. government is set to ride into orbit from Florida’s Space Coast aboard a SpaceX Falcon 9 rocket Thursday.

SpaceX’s second Falcon Heavy, outfitted to produce more thrust than the heavy-lifter’s debut flight last year, was raised vertical at launch pad 39A in Florida on Wednesday ahead of a launch attempt with the Arabsat 6A communications satellite.
