Two days prior to the docking of the Russian Multipurpose Logistics Module (MLM) to the ISS, the FDF was asked to provide contingency support as a risk mitigation. After docking, an inadvertent firing of the MLM thrusters caused ISS to lose control of its attitude and a spacecraft emergency was declared. FDF responded to the anomaly by providing additional console staffing, coordinating with all network elements, and ensuring that communication was maintained despite the unplanned thrusting.
