This week, the six-member Expedition 43 crew worked a variety of onboard maintenance tasks, ensuring crew safety and the upkeep of the International Space Station's hardware.
In this image, NASA astronauts Scott Kelly (left) and Terry Virts (right) work on a Carbon Dioxide Removal Assembly (CDRA) inside the station's Japanese Experiment Module. The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.
The crew also is packing the SpaceX Dragon space freighter readying the vehicle for its return home and splashdown May 21.
