The Mission Control team at NASA’s Johnson Space Center in Houston confirmed Friday night that a backup computer on the exterior of the International Space Station (ISS) called a Multiplexer-Demultiplexer (MDM) is not responding to commands.

The station’s MDM computers control some systems associated with robotics aboard the space station. The primary MDM operating aboard the space station is functioning normally and there is no immediate impact to space station operations.

The computer outage does not pose a risk to the six crew members aboard the space station. ISS teams are assessing next steps to attempt to bring the computer back online or replace it. Replacing the backup MDM, if needed, would require a spacewalk.

The backup MDM would provide redundancy for robotic systems that will be needed to attach the SpaceX Dragon spacecraft currently scheduled to launch on Monday and rendezvous with the ISS on Wednesday. NASA is continuing to work toward a Monday launch of the SpaceX cargo resupply mission pending further evaluations by the ISS Program.
