Early Wake Up Call on ISS
False alarms scrub airlock camp out, Reuters
“Astronauts Bill McArthur and Jeffrey Williams retired to the U.S. airlock module Monday night for what was expected to be an undisturbed night. But loud alarms rang out twice during the night due to a software glitch that falsely detected low levels of carbon dioxide. NASA cancelled the camp out at 12:43 a.m. EDT (5:43 a.m. British time), said spokesman Kyle Herring.”
