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.

On-Orbit Status Report

AstroPi: Today the crew transferred the AstroPi IR (infrared) unit to the Node 2 window in support of the upcoming European AstroPi Challenge. In this challenge, students and young people are offered the opportunity to conduct scientific investigations in space by writing computer programs that run on Astro Pi's special Raspberry Pi computers aboard ISS. Students can choose either Life in space or Life on Earth as themes for their experiments.

Payload Network Attached Storage (NAS) Vent Clean: Using the AC vacuum cleaner, the crew performed this routine maintenance to clean vents on the front, back, and left side of the Payload NAS. NAS is a file server with 5 hard drive bays that provide a total of 20 terabytes of raw disk space when used with 4 terabyte hard drives. Among other capabilities, the PL NAS supports user file transfers from their machine via web browser and allows onboard ISS systems to access a shared folder location on the NAS.

Hatch Seal Inspection: The crew completed this scheduled maintenance to clean and inspect the USOS hatch seals (Node 2, Node 3, Permanent Multipurpose Module [PMM], Japanese Experiment Module [JEM] and Columbus), hatch plate sealing surface and hatch handle mechanism for Foreign Object Debris (FOD) and/or damage.
