Two NASA astronauts are preparing for Friday's spacewalk to continue upgrading the power system of the International Space Station.
Three other Expedition 63 crew members today explored various microgravity phenomena to improve the health and industry of the earth and space.
Commander Chris Cassidy and flight engineer Bob Behnken reviewed the tools and procedures they will use on Friday's spacewalk on Monday afternoon. NASA astronaut Doug Hurley (Doug Hurley) also joined them, he will assist the duo in and out of their spacesuits and monitor their spacewalk activities. The two spacewalkers then inspected their American spacesuits and organized the Quest airlock, where they will go on a Friday excursion.
Cassidy and Behnken will set their spacesuits to internal power at around 7:35 AM Eastern Time on Friday, officially starting their spacewalk. The two will replace the old NiMH batteries with new lithium-ion batteries on the Starboard-6 truss structure. The batteries store electricity collected from the space station’s main solar array and distribute it throughout the orbital laboratory.
Hurley spent the first half of Monday studying fluid and combustion physics. He first explored how microfluidics can cause biochemical reactions in the blood, revealing the mechanism hidden on the earth. Next, he studied the manufacture of composite materials to learn how to repair and build structures in future space missions.

This year, @AstroBehnken and @Astro_Doug and their son left special memories in the #LaunchAmerica mission. This Father’s Day, listen to these dads sharing the fun of space flight with their children. pic.twitter.com/iEYdez5a9e
Material Science Laboratory-Sample Holder Assembly-Gravity Influence of Sintering Deformation (MSL SCA-GEDS)-Germany: The staff performed the required replacement of the processed scientific sample holder assembly (SCA) with the new SCA running in C3 Activity. Liquid phase sintering is an important method for manufacturing mesh composite materials suitable for a range of industries. The science of liquid phase sintering has a history of about 50 years, but the practice can be traced back to the 1400s, when gold was used to bond platinum in Colombia and Ecuador. Today, it has become a mainstay in many fields such as metal cutting tools, armor-piercing bullets, automobile engine connecting rods and self-lubricating bearings. Future applications include the use of liquid phase sintering as a means of space manufacturing and repair, such as the use of lunar weathered layers to make structures on the moon or the use of metal powders to make alternative parts during extraterrestrial exploration. The MSL SCA-GEDS-German experiment focuses on determining the basic scientific principles to predict the density, size, shape and characteristics of liquid sintered bodies of various components under the conditions of Earth's gravity (1g) and microgravity (μg).
Capillary-driven microfluidics: The staff performed a plate replacement to start the third ink cartridge run. Capillary-driven microfluidics in space (capillary-driven microfluidics) studied the suction of fluid into small tubes under microgravity. The results may improve current mathematical models and understanding of microfluidic systems, and improve fluid control in various devices. Diagnostic equipment needs to separate blood cells and plasma with different densities, and the absence of sedimentation and buoyancy-driven convection in a microgravity environment improves the efficiency of this separation.
Red eye: The crew presses the JEM airlock to prepare the JEM slide table expansion. The special purpose smart manipulator (SPDM) will capture and manipulate the REDEYE-3 satellite for deployment. The RED-EYE program developed and demonstrated the use of Kaber microsatellite deployers connected to a special purpose smart manipulator (SPDM) to improve the utility of low-cost microsatellites.
S6 Battery Extravehicular Activity (EVA) Preparation: Today, the staff of the International Space Station continued to prepare for the upcoming S6 battery upgrade EVA by performing equipment lock-in preparations for the Extravehicular Mobility Maneuver Unit (EMU) 3004 and 3006. In addition, the procedure review and procedure meeting ISS staff and ground support teams have also been completed. The first of the two S6 channel 1B battery EVAs is scheduled to be completed on June 26, 2020.
H-II transfer vehicle (HTV) 9 cargo operations: Today, the crew continues to perform HTV9 cargo transfer operations. The ground team estimates that it will take approximately 8 hours of freight operations to complete the available freight operations.
Waste and sanitary compartment (WHC) maintenance: Today, staff removed and replaced the (R&R) WHC urine container and plug-in filter. After the replacement, the WHC was functionally tested and declared that the WHC was operational. During the previous maintenance period, the staff found sediment in the pretreatment urine line downstream of the WHC pump separator. Before R&R, the staff checked the pipeline to ensure that the sediment did not return to the WHC.
