Students from Choctaw Nation Head Start, Jones Academy Elementary, and seven area public schools in Durant, Oklahoma, will have an opportunity this week to hear from a NASA astronaut aboard the International Space Station.

The Expedition 68 astronauts are cleaning up following three days of advanced bone repair studies while getting ready for an upcoming spacewalk. The International Space Station’s three cosmonauts continued their space physics and Earth imagery work, as well as maintained orbital lab systems.
NASA Flight Engineers Josh Cassada and Frank Rubio are cleaning up biology research hardware and finalizing sample processing after three full days of bone healing research. The duo worked inside the Kibo laboratory module servicing the samples then stowing them into science freezers. Those samples will be packed on a future SpaceX Dragon cargo mission for return then analyzed and compared to control samples in laboratories on Earth. The two astronauts also cleaned Kibo’s Life Science Glovebox and its components where the intensive bone investigation work took place this week.
Cassada also worked on space agriculture today collecting leaves from thale cress plants housed inside the Advanced Plant Habitat for stowage and analysis on Earth. He later tended to tomato plants growing inside the Veggie space botany facility for the Veg-05 experiment. Both studies are taking place inside the Columbus laboratory module.
Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata explored ways to enable on-demand production of nutrients for astronauts on long-term missions to the Moon, Mars, and beyond. The technology demonstration uses engineered microbes, or yeast, to ensure a safe and simple food production environment in space and offset the degradation of nutrients stowed over long periods.
The next spacewalk to continue upgrading the orbiting lab’s power generation system is planned for Feb. 2. Two spacewalkers will exit the Quest airlock in their Extravehicular Mobility Units (EMUs), or spacesuits, to finish installing a modification kit on the starboard truss structure. The hardware installation job will ready the space station for its next roll-out solar array. Ahead of the upcoming spacewalk, spacesuit gloves and tethers were inspected.
Commander Sergey Prokopyev continued more space physics experiment runs on Thursday as he explored how clouds of highly charged particles, or plasma crystals, behave in microgravity. Flight Engineer Dmitri Petelin of Roscosmos spent his day on life support maintenance before partnering with fellow cosmonaut Anna Kikina for ultrasound eye scans. Kikina resumed her Earth observations using ultraviolet imaging hardware to obtain a map of the nighttime glow of Earth’s atmosphere.

Wednesday was the last full day of research operations aboard the International Space Station to learn how to improve bone healing therapies both on Earth and in space. The Expedition 68 crew members also studied the human heart and plasma physics and set up Earth imagery hardware.
NASA astronauts Nicole Mann, Josh Cassada, and Frank Rubio and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata wrapped up three days of continuous research into bone growth. The quartet spent the day inside the Kibo laboratory module studying research samples in the Life Science Glovebox to understand the bone healing process in microgravity. Cassada will work on Thursday and Friday cleaning up the space biology hardware and completing sample processing.
Weightlessness inhibits bone tissue regeneration, or bone repair, and the Osteopromotive Bone Adhesive investigation seeks to reverse these effects on stem cells and bone tissue. Insights gained from the biology experiment may help doctors provide advanced treatments for bone injuries that occur in space and improve therapies for conditions on Earth such as osteoporosis.
Cardiac research in space is also very important as two cosmonauts joined each other on Wednesday morning learning how the circulatory system is impacted by long-term microgravity. Commander Sergey Prokopyev attached sensors to himself, with assistance from Flight Engineer Dmitri Petelin, for the cardiac study. The experiment seeks insights into how the heart adapts to microgravity and to prepare for the effects of returning to Earth’s gravity months later.
Prokopyev also continued this week’s space physics work studying the behavior of plasma crystals, or clouds of highly charged particles, inside a specialized chamber. Petelin studied kept up his observations of fluids exposed to magnetic and electric fields in microgravity. Both studies have the potential to advance space and Earth-bound industries as well as improve fundamental knowledge.
Flight Engineer Anna Kikina of Roscosmos began her day pointing a camera outside station windows and photographing the external condition of the Nauka, Zvezda, and Rassvet modules. She finished her shift installing and activating gear that will acquire ultraviolet imagery of Earth’s nighttime atmosphere.
The next SpaceX crewed mission to the space station is soon approaching. The Crew-6 crewmates are Commander Stephen Bowen and Pilot Warren “Woody” Hoburg, both from NASA, and Mission Specialists Andrey Fedyaev from Roscosmos and Sultan Alnedayi from the Mohammed bin Rashid Space Centre. The quartet will lift off aboard SpaceX Crew Dragon Endeavour at 2:07 a.m. EST on Feb. 26 and dock to the Harmony module’s space-facing port just over half-a-day later.
