Live coverage: Soyuz crew lands in Kazakhstan

With one last task to carry out, a space station Cygnus cargo ship loaded with trash and no-longer-needed equipment fell back to Earth Wednesday, hitting the discernible atmosphere 60 miles or so above the Pacific Ocean at nearly 5 miles per second.

SpaceX launched its Falcon 9 rocket at 2 a.m. EDT (0600 GMT) Thursday, two days after high winds prevented liftoff. The nearly 23-story booster carried the EchoStar 23 communications satellite into orbit from NASA’s Kennedy Space Center in Florida to provide broadcast television programming across Brazil.

Citing medical reasons, Russia’s space agency announced Wednesday that it is replacing two cosmonauts who were scheduled to fly on the next Soyuz mission to the International Space Station in April with backup crew members.
