The U.S. Navy has declared the primary orbit-raising system aboard its new MUOS No. 5 communications satellite failed, leaving controllers scrambling to design a rescue plan.

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.

Boeing’s Starliner crew capsule flew into the wrong orbit soon after lifting off from Cape Canaveral on an unpiloted demonstration flight Friday morning, burning too much fuel and precluding the new commercial spaceship from docking with the International Space Station. Mission managers say the capsule will target an early landing in New Mexico Sunday.
