Live coverage: Space station crew back on Earth

SpaceX launched a Falcon 9 rocket Sunday from Cape Canaveral with 143 small satellites, a record number of spacecraft on a single mission, giving a boost to startup space companies and stressing the U.S. military’s tracking network charged with sorting out the locations of all objects in orbit.

Orbital ATK’s Antares rocket will deliver the commercial Cygnus supply ship to an orbit with an altitude between 130 miles and 179 miles within about nine minutes of liftoff from Virginia’s Eastern Shore.

A SpaceX Falcon 9 rocket ferried a multinational crew into orbit at the break of dawn Friday with a spectacular sky-lighting launch from NASA’s Kennedy Space Center in Florida, dazzling early risers along the East Coast with a flawless start to a planned six-month expedition on the International Space Station.
