Shuttle Atlantis unwrapped ahead of public debut

SpaceX’s second Falcon Heavy rocket lifted off Thursday with the Arabsat 6A communications satellite. The world’s most powerful operational launcher lifted off from pad 39A at NASA’s Kennedy Space Center in Florida at 6:35 p.m. EDT (2235 GMT), and its three first stage boosters landed less than 10 minutes later — two back at Cape Canaveral and one on a drone ship at sea.

SpaceX’s new Falcon Heavy rocket successfully soared into orbit Tuesday, and its two strap-on boosters came back to Cape Canaveral for an electrifying double-landing punctuated by quadruple sonic booms.

A SpaceX Falcon 9 rocket is scheduled to take off Thursday from Florida’s Space Coast with a secret cargo for the National Reconnaissance Office, which broke with standard practice to procure the launch commercially, outside of the government’s established contracting schemes.
