SIMULATION #6 UNDERWAY
Simulation #6 is in-progress. In this simulation we successfully spun up science gyroscope #2 and we successfully performed the low temperature bakeout. Two key anomalies occurred during the running of this simulation; one was a planned anomaly used to train the staff for press conferences; the other was an unplanned GSE induced anomaly causing the activation of a number of safe mode actions. The team responded well to these issues. Action items from simulation #6 are in-work.
