Watch as Progress docks with Space Station bringing a holiday delivery

A twin-engine Northrop Grumman Antares rocket climbed into orbit Saturday from Virginia’s Eastern Shore carrying a Cygnus supply ship bound for the International Space Station with a compact electron microscope, a flame combustion experiment, a range of biological investigations, fresh cheese, fruit and vegetables for the research lab’s three-person crew.

Clad in white spacesuits, astronauts Scott Kelly and Kjell Lindgren recently floated outside the International Space Station on a pair of spacewalks, and the duo carried cameras with them to document the excursions.

Concern about a possible ammonia coolant leak Wednesday prompted astronauts on the International Space Station to evacuate the U.S. segment of the complex and shelter in the Russian portion of the outpost while flight controllers scrambled to untangle initially confusing telemetry.
