Two Expedition 59 cosmonauts are finalizing reviews before Wednesday morning’s spacewalk for maintenance outside the International Space Station. Meanwhile, the orbital residents are also readying completed experiments for return to Earth inside the SpaceX Dragon cargo craft next week.

Commander Oleg Kononenko is set to begin his fifth career spacewalk Wednesday at 11:44 a.m. EDT. He will lead first-time spacewalker Alexey Ovchinin during the six-hour-15-minute excursion on the Russian segment of the orbital lab. They will retrieve experiment hardware, clean lab windows and jettison old cables among other tasks.

The duo reviewed their spacewalk tasks and worksites alongside NASA astronaut Christina Koch this morning. Koch will assist the pair with their Russian Orlan spacesuits in the Pirs airlock before and after Wednesday’s spacewalk.

The SpaceX Dragon launched a multitude of life science experiments studying immunology, crystallography, microphysiology and other space phenomena to the station May 4. The completed research samples and science hardware will now return to Earth inside Dragon after it departs the station’s Harmony module June 3. NASA Flight Engineer Anne McClain is readying the commercial space freighter for departure and beginning the work to pack the finalized experiments for analysis in labs across the globe.

Astronauts Nick Hague and David Saint-Jacques spent Tuesday maintaining station systems and hardware. Hague first measured airflow in the Japan’s Kibo laboratory module before routing power cables in the U.S. Destiny laboratory module. Saint-Jacques reconfigured a robotics computer and routed communication cables then checked components on the Advanced Resistive Exercise Device.

The Expedition 59 crew is starting the Memorial Day weekend studying biology, physics and orbital manufacturing techniques. The space residents will also be busy on the U.S. holiday conducting more research and getting ready for the year’s fourth spacewalk at the International Space Station on Wednesday.

Astronaut David Saint-Jacques of the Canadian Space Agency (CSA) analyzed his own blood sample today testing the new Bio-Analyzer. The biomedical device from the CSA tests a variety of biomarkers to measure molecular signs of health on the station. He also worked on another biology platform that can produce gravity levels up to 2g for research on an array of materials and small organisms.

Japan’s Kibo laboratory module enables astronauts to place and retrieve space exposure experiments outside of the orbiting lab. Flight Engineer Nick Hague swapped some of those exposed samples today from a platform inside Kibo. The long-running materials exposure studies at the station help scientists understand how microgravity and radiation affect a variety of materials.

Christina Koch of NASA continued exploring the production of superior quality optical fibers inside the U.S. Destiny lab module’s Microgravity Science Glovebox. The variety of elements used in the manufacturing process are difficult to control on Earth with gravity bearing down on them. The space-created samples will be analyzed on the ground for their potential to improve a variety of applications such as medicine, navigation, communication and atmospheric monitoring.

At the end of the day, Flight Engineer Anne McClain checked out emergency space navigation techniques using a sextant. She peered at constellations from the cupola during an orbital night period while inspecting and calibrating the hand-held device.

Meanwhile, Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin continued setting up their spacesuits and tools today. Next week they will review procedures and timelines for their approximately six-hour spacewalk for external maintenance scheduled for around 11:45 a.m. EDT Wednesday.

The Expedition 59 astronauts focused on DNA editing, high-end physics and free-flying robotics aboard the International Space Station today. Two cosmonauts are also ramping up their preparations for next week’s spacewalk.

The orbiting complex is flying higher today after a docked Russian cargo craft fired its engines for 20 minutes. The orbital reboost places the station in the correct trajectory for the undocking and landing of three Expedition 59 crewmembers June 24.

The wide range of advanced space research taking place every day on the orbiting lab benefits humans on Earth and in space. Scientists use the results to treat terrestrial ailments and the negative impacts of microgravity more effectively. Engineers also take the data to improve industrial and commercial processes and design safer, more advanced spacecraft and habitats as NASA prepares to go to the Moon in 2024.

NASA astronaut Nick Hague is researching how space radiation damages DNA today using the CRISPR genome-editing tool. The Genes in Space-6 study also uses DNA extraction and sequencing tools to observe how the damaged DNA repairs itself in space. Results may advance the development of treatments for radiation exposure hazards in harsh environments.

Space manufacturing eliminates the detrimental effect of Earth’s gravity and may provide superior results than on Earth. Flight Engineer Christina Koch of NASA set up hardware in the Microgravity Science Glovebox to explore the production of high-quality optical fibers on the station. The study seeks to create a high commercial value product benefitting both Earth and space industries.

The Astrobee robotic assistant is being checked out today by Canadian Space Agency astronaut David Saint-Jacques. He set up the cube-shaped robotic free flyer to map the inside the of Kibo laboratory module and spun it rapidly afterward calibrating its navigation camera. Astrobee is being tested for its ability to perform routine maintenance duties and provide additional lab monitoring capabilities.
