Shuttle Atlantis unwrapped ahead of public debut

SpaceX tested astronaut slidewire escape baskets and fire suppression capabilities Friday at launch pad 39A in Florida, demonstrating systems that would be activated in the event of an emergency before liftoff of a crewed mission.

With eyes on Tropical Storm Eta approaching South Florida, the four astronauts set to launch next Saturday on a SpaceX Crew Dragon spacecraft arrived at NASA’s Kennedy Space Center on Sunday after flying from their home base in Houston.

SpaceX’s next Falcon 9 booster is being readied for liftoff from Cape Canaveral, but most of the launcher’s ascent into orbit will be under a news blackout at the request of the U.S. government customer that owns the top secret Zuma payload fastened to the top of the rocket.
