Mission Specialists Mike Foreman and Randy Bresnik began their mission’s second spacewalk a little later than planned today at 9:31 a.m. EST. Even though they started late, the spacewalkers plan to get all the scheduled tasks complete during what will now be a six-hour-long spacewalk.

That is 30 minutes shorter than was originally planned, which means that they will not have extra time in the schedule for get ahead work.

The International Space Station again experienced a false depressurization alarm that originated from the new Poisk Mini-Research Module overnight. The station’s automatic response resulted in a shutdown of ventilation systems, which led to two smoke detectors issuing a false alarm, as well – one in the Columbus European laboratory and one in the Quest airlock, where Foreman and Bresnik were camping out as part of the pre-breathe protocol that precedes spacewalks.

The alarm sounded at 9:53 p.m. Friday, more than two hours after Atlantis’ crew went to sleep for the night. Emergency procedures required the spacewalkers to move out of the airlock while teams on the ground verified that the alarms were false.
