The veteran spacewalkers wrapped up a spacewalk on Friday after six hours and 7 minutes swapping five aging nickel-hydrogen (NiH2) batteries with two new lithium-ion (Li-Ion) batteries. They will go out again on Wednesday starting at 7:20 a.m. EDT to swap one more NiH2 battery for a Li-Ion battery on the Starboard-6 truss structure worksite. NASA TV will begin its live coverage at 6 a.m.
Flight Engineer Doug Hurley joined his Expedition 63 crewmates today in a review of Wednesday’s spacewalk procedures with ground specialists. Hurley once again will assist Cassidy and Behnken in and out of their spacesuits and monitor the pair during the excursion.
Space station managers also are planning two more spacewalks in July to keep up the battery upgrades. After Cassidy and Behnken complete Wednesday’s spacewalk, mission planners will finalize the future spacewalk tasks along with target dates and times.
Cosmonauts Anatoly Ivanishin and Ivan Vagner spent Monday working on a variety of Russian communications gear and life support hardware. The duo also worked on a pair of Earth science studies exploring how natural and man-made activities on the surface affect the upper and lower atmosphere.
Cassidy and Behnken will be removing existing nickel-hydrogen batteries and replacing them with new lithium-ion batteries that arrived on a Japanese cargo ship last month. The batteries store electricity for one pair of the station’s solar arrays, and the swap will upgrade the station’s power supply capability. The batteries store power generated by the station’s solar arrays to provide power to the microgravity laboratory when the station is not in sunlight as it circles Earth during orbital night.
This is the 228th spacewalk in support of space station assembly and maintenance. Cassidy is extravehicular crew member 1 (EV 1), wearing the spacesuit with red stripes, and using helmet camera #18. Behnken is extravehicular crew member 2 (EV 2), wearing the spacesuit with no stripes and helmet camera #20. It is the seventh spacewalk for both astronauts.
The duo will set their spacesuits to battery power about 7:35 a.m. EDT Friday, signifying the start of their spacewalk, which may last as long as seven hours. NASA will begin its live coverage on NASA Television and the agency’s website at 6 a.m.
NASA posted a video providing an animation of the spacewalk activities to depict how they will be replacing existing nickel-hydrogen batteries on one of two power channels on the far starboard truss (S6 Truss) of the station with new lithium-ion batteries that arrived on a Japanese cargo ship last month.
They are scheduled for a second spacewalk to continue the work on Wednesday, July 1. The battery replacement work is the final series of power upgrade spacewalks that began in January 2017.
This will be the 228th spacewalk in support of space station assembly and maintenance. Cassidy will be extravehicular crew member 1, wearing the spacesuit with red stripes, while Behnken will be extravehicular crew member 2, wearing the spacesuit with no stripes. It will be the seventh spacewalk for each astronaut.
They will disconnect aging nickel-hydrogen batteries from the Starboard-6 truss structure and stow them on an external pallet. The duo will then install new lithium-ion batteries in their place upgrading the orbital lab’s power systems. The batteries store power collected from the main solar arrays and for use throughout the station.
Cassidy and Behnken organized their spacewalk tools and readied their U.S. spacesuits inside the Quest airlock during the morning. They were joined in the afternoon by Flight Engineers Doug Hurley of NASA and Ivan Vagner of Roscosmos for a quick review of tomorrow’s spacewalk procedures.
Hurley and Vagner have been reviewing their roles all week to assist tomorrow’s spacewalk. The pair will help the spacewalkers in and out of the Quest airlock as well as their spacesuits. Both crewmembers will also monitor and help choreograph the spacewalk, in conjunction with specialists on the ground, from inside the station.
NASA TV begins its live coverage of the spacewalk activities at 6 a.m. This will be the seventh spacewalk for both Cassidy and Behnken who each have conducted six spacewalks on previous missions at the space station.
Veteran cosmonaut Anatoly Ivanishin spent his morning on lab maintenance on the station’s Russian segment. Afterward, Ivanishin set up sensors to monitor the radiation environment in the orbital lab.

Following a day of spacesuit fit checks, the three NASA astronauts aboard the orbiting lab split up on Wednesday to keep space science moving along. Commander Chris Cassidy started the day servicing a science freezer that stores biological samples for analysis. During the afternoon, Cassidy checked on samples for a physics study with commercial applications taking place in the Fluid Science Laboratory rack.
The duo ended the day conducting a medical emergency drill in space. Hurley and Behnken practiced cardiopulmonary resuscitation (CPR) techniques, located medical equipment and coordinated communications with mission controllers.
Hurley also joined cosmonaut Ivan Vagner in the morning and reviewed their responsibilities to assist Cassidy and Behnken during Friday’s spacewalk. Hurley and Vagner will help the astronauts in and out of their spacesuits and monitor the spacewalk scheduled to start about 7:35 a.m. EDT. NASA TV begins its live broadcast at 6 a.m.
Vagner then partnered up with veteran cosmonaut Anatoly Ivanishin for cargo operations inside Russia’s Progress 74 cargo craft. Ivanishin spent the rest of the day working on Russian science experiments and life support maintenance.
