U.S. EVA-49

Veteran spacewalkers Drew Feustel and Ricky Arnold, both with prior experience working outside the International Space Station, are set for a six-and-a-half-hour excursion on March 29 to complete a series of outfitting and repair tasks on the exterior of the U.S. Segment. The 209th EVA in ISS Assembly, Maintenance & Upgrades has the primary objective of expanding the Space Station's external WiFi network for an upcoming ecosystem-sensing instrument arriving later this year. Additional EVA objectives include the removal of a pair of ammonia hosts to return to the ground for leak inspection and the replacement of a camera group on the Station's truss that lost its ability to pan and tilt.
