Live coverage: Space station crew safely returns to Earth

Bound for the International Space Station with a max load of fresh supplies, a commercially-operated cargo ship was mounted atop its booster rocket today for liftoff from Cape Canaveral on March 22.

The first launch of a Russian Proton rocket since June has been delayed until at least January to conduct additional checks on the three-stage booster and its Breeze M upper stage, Russian space officials said.

Astronauts Butch Wilmore and Terry Virts suited up and ventured outside the International Space Station on Sunday on their third spacewalk in eight days to install equipment to help future commercial crew capsules built by Boeing and SpaceX navigate to the complex.
