Live coverage: Dragon supply ship back on Earth

A Russian Progress cargo spacecraft laden with 5,300 pounds of fuel and supplies blasted off from the Baikonur Cosmodrome in Kazakhstan on Saturday, riding a Soyuz rocket smoothly into orbit on the first of two resupply launches heading for the International Space Station in the next two days.

A Falcon 9 rocket lifted off from Vandenberg Air Force Base at 4:39 a.m. PDT (7:39 a.m. EDT; 1139 GMT) Wednesday, and SpaceX successfully landed the rocket’s first stage on a drone ship in the Pacific Ocean. The mission’s primary objective is the deployment of 10 Iridium Next communications satellites into low Earth orbit.

NASA astronaut Mark Vande Hei and two cosmonauts blasted off from Kazakhstan Friday and docked with the International Space Station after a two-orbit chase, the first step in a record crew rotation requiring two launches and two landings with four different spacecraft in just three weeks.
