NASA is working to keep space station going despite bluster from Russia
Work continues onboard the orbiting laboratory as it does every day. On Tuesday, the day Russia announced it was leaving the station, Russia's Oleg Artemyev, the current space station commander, was working on a cardiac research study designed to help doctors learn how to keep astronauts safe on long-duration space missions. Along with fellow cosmonaut Denis Matveev, he helped put away the tools used in a spacewalk last week while the third cosmonaut on the station, Sergey Korsakov, was checking the robotic arm on the Russian side of the station.
