Carrying more science research gear to the International Space Station than ever launched before by U.S. commercial logistics vehicles, the next Orbital ATK Cygnus freighter takes flight Tuesday.

A day after launching from the Kennedy Space Center, NASA astronauts Doug Hurley and Bob Behnken docked with the International Space Station aboard SpaceX’s Crew Dragon spacecraft at 10:16 a.m. EDT (1416 GMT) Sunday to complete a 19-hour transit on the new commercial crew capsule.

Two astronauts floated outside the International Space Station early Friday for the first of four planned spacewalks to wrap up a complex multi-year job to replace 48 aging batteries in the lab’s solar power system with 24 more powerful lithium-ion units.
