Description : 29 Mars 2018 - EVA 1
Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA completed a spacewalk lasting 6 hours, 31 minutes, moving the Pump Flow Control Subassembly (PFCS) from a spare parts platform on the station’s truss to the Dextre robotic arm.
On March 29, 2018 Andrew Feustel and Richard Arnold performed an unscheduled spacewalk (6h 10m). They installed wireless communications equipment (External Wireless Communications - EWC) on the station’s Tranquility module to enhance payload data processing for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) experiment being flown to the station on a future SpaceX Dragon cargo spacecraft (planned in June 2018). The experiment will measure the temperature of plants on Earth to better understand how much water they need and how they respond to stress.
The crew members also swapped out high-definition video cameras on the port truss of the station’s backbone and removed aging hoses from a cooling component on the station’s truss.
12 MAY 2018 - EVA 2
The second spacewalk in this expedition occurred on May 16, 2018 by Andrew Feustel and Richard Arnold (6h 31m). They moved a component called a Pump Flow Control Subassembly (PFCS) from a spare parts platform on the station’s truss "backbone" to the Special Purpose Dexterous Manipulator (Dextre) robotic arm. The PFCS drives and controls the flow of ammonia through the exterior portions of the station’s cooling system. Robotics controllers on Earth used Canadarm2 and Dextre to perform final installation on the port-side truss for checkout. The spacewalkers removed a failed PFCS and return it to the spare parts depot. They also replaced a camera system on the Destiny Laboratory and a communications receiver.
