The Expedition 59 crew is going into the weekend preparing for another spacewalk on Monday. The International Space Station residents also continue microgravity research as they wait for two U.S. cargo ships to arrive before the end of the month.

Astronauts Anne McClain and David Saint-Jacques are getting their tools ready for another power upgrades spacewalk and will wrap up their final procedures review on Sunday. The spacewalkers will set their spacesuits to battery power around 8:05 a.m. EDT Monday signifying the start of their spacewalk and exit the space station’s Quest airlock.

The duo will work outside for about six-and-a-half hours installing truss jumpers to provide a redundant power source to the Canadarm2 robotic arm. McClain and Saint-Jacques will also install cables to update the station’s External Wireless Communications system. NASA TV starts its live coverage at 6:30 a.m. Monday.

Russia’s Progress 72 (72P) resupply ship delivered over 3.7 tons of food, fuel and supplies after docking to the Pirs docking compartment Thursday morning. Next up is Northrop Grumman’s Cygnus space freighter when it launches from Virginia on April 17 on a two-day ride to the station’s Unity module. SpaceX follows in late April when its Dragon cargo craft blasts off from Florida on a two-day trip to the orbital lab’s Harmony module.

Virtual reality filming and space research continued full pace inside the orbital lab today. Flight Engineer Christina Koch first strapped herself into an exercise bike to measure her aerobic capacity then set up a virtual reality camera inside the Unity module today. Nick Hague of NASA then recorded himself describing his space experiences for a short immersive, cinematic film.

Cosmonauts Oleg Kononenko and Alexey Ovchinin unloaded the new 72P and worked on an array of life science experiments in the orbital lab’s Russian segment. The duo photographed red blood samples and microbes to help doctors keep long-term crews healthy in space.
