Shuttle Atlantis unwrapped ahead of public debut

The Falcon 9 booster that launched four astronauts toward orbit last weekend arrived back on Florida’s Space Coast Thursday aboard a SpaceX drone ship, sailing into Port Canaveral with a lean but otherwise in seemingly good shape after it apparently slid across the ship’s deck in high winds and rough seas. Assuming post-flight inspections reveal no major issues, SpaceX aims to reuse the booster to launch the next Crew Dragon mission in 2021.

In one of its final preflight tests, a SpaceX Falcon 9 rocket ignited at pad 39A in Florida for several seconds Thursday, ramping up to full throttle in an end-to-end checkout of the booster before liftoff next week on a space station resupply flight.

A decade in the making, the core stage for NASA’s first Space Launch System heavy-lift rocket rolled into the Vehicle Assembly Building at the Kennedy Space Center Thursday to join up with twin solid rocket boosters and an Orion capsule for an unpiloted test flight around the moon.
