On Nov. 23, the team in Mission Control Houston performed a change in electrical power routing to remove one of the eight International Space Station power channels from use. This procedure was performed in response to unexpected readings and intermittent tripping of the 1B power channel in the overnight hours. When the power channel tripped, the batteries were no longer charged at expected levels so flight operators moved the 1B powered equipment from 1B to 1A. Space station systems are in a stable configuration, and the team is evaluating the event and discussing forward plans. Upcoming space station operations including Saturday’s launch of NASA and SpaceX’s 26th commercial resupply mission, as well as spacewalks are not impacted.
