The International Space Station isn't working quite right. A NASA ISS update issued Monday focused on an upcoming
cargo resupply mission, but also mentioned "an issue with the International Space Station's electrical power system."
said the issue stems from a main bus switching unit (MBSU) that sends electrical power to two of eight power channels. The ISS solar arrays feed power through these channels to operate all of the station systems. Flight controllers are working on rerouting power through the six remaining channels.
NASA is trying to figure out what happened and if it can restore full power to the station. "There are no immediate concerns for the crew or the station," the space agency said. The ISS is currently home to six astronauts and cosmonauts from NASA, the Canadian Space Agency and Roscosmos.
A SpaceX Dragon resupply mission is scheduled to launch this week, but the power issue could put a crimp in those plans. "Discussions are underway to determine any impacts to SpaceX's CRS-17 cargo resupply mission targeted for launch May 1," NASA said.
