Live coverage: Space station crew concludes 186 days in orbit

Blue Origin says it is “very, very close” to flying humans on suborbital launches to the edge of space after a successful test flight of a human-capable rocket and capsule Thursday.

Russian cosmonauts Alexander Misurkin and Anton Shkaplerov floated outside the International Space Station on Friday and installed an upgraded electronics box on a high-gain communications antenna at the aft end of the Zvezda service module.

The Atlas 5 rocket emerges from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station. Liftoff is set for Thursday at 5:55 p.m. EST.
