Two American astronauts will take a 6.5-hour spacewalk outside the International Space Station on Thursday, March 29.
Expedition 55 flight engineers Andrew Feustel and Ricky Arnold are scheduled to exit the station at approximately 9 a.m. EDT.
The spacewalk will be the seventh for Feustel's career and the third for Arnold's career.
According to NASA, the astronauts "will install wireless communications equipment 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. 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 will swap out high-definition video cameras on the port truss of the station’s backbone and remove aging hoses from a cooling component on the station’s truss."
