(NASA) – In the wake of problems Sunday with the International Space Station’s Command and Control computers, the crew had a mostly off-duty day Monday, taking time for an emergency egress drill that is conducted periodically to maintain crew proficiency.

Space shuttle Endeavour is home after two weeks in space, having delivered the final U.S. module and a “room with a view” to the station. STS-130 Commander George Zamka guided Endeavour to a landing at the Kennedy Space Center’s Shuttle Landing Facility at 10:20 p.m. EST Sunday, to wrap up a 5.7-million-mile mission.

Meanwhile, flight controllers in Houston’s Mission Control Center isolated the issue that caused the three Command and Control computers to switch their roles as primary, backup and standby units.

Station Spacecraft Communicator Stan Love told Expedition 22 Commander Jeff Williams that the glitches were caused by S-band telemetry software that takes Columbus laboratory data, puts it into packets and sends it to the ground. For now, that particular piece of code will be bypassed and flight controllers will command the remaining systems back to their normal configurations, including Ku-band communications.
