Shuttle Atlantis unwrapped ahead of public debut

The power and propulsion section of Orbital ATK’s next Cygnus supply ship, featuring new solar panel and fuel tank designs, arrived at NASA’s Kennedy Space Center in Florida on Wednesday to be joined with a cargo module for a Dec. 3 launch to the International Space Station.

Liftoff of a previously-flown Falcon 9 rocket from NASA’s Kennedy Space Center with a European-built television broadcast satellite has been pushed back from Saturday until at least next Wednesday night, officials said.

Maintaining a brisk flight rate three days after its last launch, SpaceX sent a Falcon 9 booster powered by a reused first stage into orbit Wednesday evening from Florida with an Airbus-built communications satellite for SES and EchoStar.
