Shuttle Atlantis unwrapped ahead of public debut

The Falcon Heavy rocket was lowered to the horizontal position before sunrise Friday morning after less than a day standing at the launch pad.

SpaceX scrubbed the planned launch from the Kennedy Space Center of a Falcon 9 rocket Friday with the company’s next 57 Starlink Internet satellites and a pair of commercial Earth-imaging surveillance satellites. Officials did not immediately confirm a new target launch date.

The launch of the next test flight of Boeing’s Starliner crew capsule has been delayed to no earlier than April 2 after workers replaced spacecraft avionics units damaged in a power surge during testing.
