Amazonseller center: Astronauts replace old batteries in 1st of 5 spacewalks

Astronauts hustled through the first of five spacewalks to replace old batteries at the International Space Station on Sunday. Christina Koch and Andrew Morgan removed three old batteries and installed two new ones delivered just a week ago, getting a jump on future work. Koch and Morgan will venture back out Friday for more battery work 250 miles (400 kilometers) up.
