Expedition 59 Flight Engineers Nick Hague and Anne McClain of NASA will begin a spacewalk outside of the International Space Station at about 8 a.m. EDT Friday, March 22. NASA Television coverage of the spacewalk will begin at 6:30 a.m.
Watch the spacewalk on NASA TV and on the agency’s website.
This will be the 214th spacewalk in support of space station assembly and maintenance. McClain will be designated extravehicular crewmember 1 (EV 1), wearing the suit with red stripes. Hague will be designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes.
This is the first of two battery replacement spacewalks this month. McClain and Hague will replace nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station’s solar arrays. The batteries were transported to the station in September aboard the Japanese H-II Transfer Vehicle. The spacewalking work continues the overall upgrade of the station’s power system that began with similar battery replacement during spacewalks in January 2017.

Two Expedition 59 astronauts are checking their spacesuits today and reviewing procedures one final time before tomorrow’s spacewalk. The other four residents aboard the International Space Station assisted the spacewalkers, maintained the orbital lab and conducted space science.
NASA Flight Engineers Anne McClain and Nick Hague readied the Quest airlock today where they will begin the first spacewalk of 2019 Friday at 8:05 a.m. EDT. The spacewalkers will work outside for about 6.5 hours of battery upgrade work on the Port-4 truss structure. NASA TV begins its live spacewalk coverage at 6:30 a.m.

The duo also confirmed their U.S. spacesuits are ready for the excursion with all the necessary components, such as helmet lights and communications gear, installed. Afterward, Hague and McClain conducted one more spacewalk timeline review.
They then joined astronauts Christina Koch and David Saint-Jacques for a final conference with spacewalk experts in Mission Control. Both astronauts also charged and set up GoPro cameras before attaching them to the spacewalkers’ suit helmets.
Koch started her day cleaning ventilation screens in the Unity module and installing lights in the Permanent Multi-purpose Module. Saint-Jacques set up the AstroPi science education hardware in the Harmony module’s window then swapped fan cables in the Life Sciences Glovebox.
Commander Oleg Kononenko and fellow cosmonaut Alexey Ovchinin spent the majority of their day in the station’s Russian segment. Kononenko and Ovchinin first collected and stowed their blood samples in a science freezer for a Russian metabolism experiment. Ovchinin then unpacked supplies from the recently arrived Soyuz MS-12 crew ship. Kononenko also worked on heart and radiation detection research before assisting the U.S. spacewalkers.

The Expedition 59 crew is busy preparing for the first spacewalk of 2019 set to begin in just two days. Meanwhile, the orbital residents are still exploring the effects of space on their bodies while familiarizing themselves with emergency hardware.
NASA astronauts Nick Hague and Anne McClain continued organizing their tools this morning ahead of Friday morning’s spacewalk. The duo will enter the Quest module’s crew airlock and their spacesuits will go on battery power Friday around 8:05 a.m. EDT signaling the beginning of the spacewalk.

Hague and McClain will spend about six-and-a-half hours upgrading the International Space Station’s storage capacity. They will swap out old nickel-hydrogen batteries with new lithium-ion batteries and install battery adapter plates on the Port-4 truss structure. NASA TV begins its live space coverage Friday at 6:30 a.m.
Hague started Wednesday, however, in the Columbus lab module helping scientists understand how microgravity impacts the perception of time. McClain collected light measurements in the afternoon from two laboratory modules and the Quest airlock to document how new station LED lights affect crew wellness.
The station’s latest crew arrivals spent a couple of hours Wednesday morning checking out safety and communications gear. Hague along with Flight Engineers Christina Koch and Alexey Ovchinin split their time between the station’s U.S. and Russian segments looking at emergency hardware and procedures.
