Shuttle Atlantis unwrapped ahead of public debut

SpaceX’s first Falcon Heavy rocket is expected to roll out to pad 39A at NASA’s Kennedy Space Center for the first time next month for a hold-down firing of its 27 Merlin main engines, but the mega-rocket’s inaugural test launch will slip into January, officials confirmed Tuesday.

SpaceX launched a Korean communications satellite from Florida on Monday aboard the company’s third Falcon 9 rocket flight of the month. Liftoff from NASA’s Kennedy Space Center occurred at 3:34 p.m. EDT (1934 GMT), and the Falcon 9’s first stage landed on a floating barge in the Atlantic Ocean a few minutes later.

A SpaceX Falcon 9 rocket took off from Kennedy Space Center’s launch pad 39A on Thursday, then its first stage booster touched down on a nearby landing target after sending a U.S. Air Force X-37B spaceplane toward orbit.
