Emergency Simulation On Board Training (OBT): Today, the crew participated in a training exercise for ISS fire and rapid depressurization emergency scenarios. The emergency training consisted of crew and ground controllers utilizing simulator data to identify each of the emergency scenarios and executing the appropriate response procedure(s). During the exercise, the crew physically translated through ISS to the appropriate response locations to visualize the use of equipment and interfaces. The teams also practiced communication and coordination with the mission control centers in Houston and Moscow for each scenario. A post-simulation crew conference was conducted to discuss and evaluate the crew/ground control responses during the training exercise.
USOS Isolation Gather: Today, the crew gathered items to be transferred to the Russian segment for the upcoming USOS isolation period. The ECLS Community has been tracking an increase in nominal atmosphere leakage since September 2019. The crew will close several module hatches tomorrow in order for the ground team to monitor pressures throughout the weekend. The crew will remain isolated in the Russian Segment (SM/MRM2/Soyuz/Progress) until Monday afternoon.
