The mission’s second spacewalk is proceeding well.
After Nicholas Patrick removed a quick disconnect cap, a small amount of ammonia crystals was observed. Based on conservative flight rules, Patrick’s suit is considered contaminated, although Patrick reported that he could not see any crystals on his suit.
If crystals are discerned, Patrick will try and wipe them off before reentering the airlock. As a precaution, the astronauts will spend additional time in the airlock to allow for any possible flakes to be cleansed from their suits through the airlock environmental system.
Inside the station, astronauts have completed the installation of the Advanced Resistive Exercise Device (ARED) in the Tranquility node.
