Two astronauts took the morning off on Friday following a spacewalk the day before while the rest of the Expedition 68 crew conducted the latest space experiments and lab maintenance tasks. Meanwhile, the International Space Station is orbiting higher today to get ready for a pair of spaceships arriving this month.

Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) relaxed Friday morning after conducting a six-hour and 41-minute spacewalk on Thursday. The duo completed the installation of hardware on the station’s Starboard-4 truss readying the orbiting lab for its next roll-out solar array. The pair then went into the afternoon with standard post-spacewalk medical checks before cleaning up the Quest airlock where their spacewalking tools and Extravehicular Mobility Units (EMUs), or spacesuits, are stowed.

NASA astronauts Josh Cassada and Frank Rubio had their hands full on Friday as they explored how weightlessness affects a wide range of phenomena including biotechnology, agriculture, and physics. The ongoing microgravity studies provide scientists and engineers new insights that could promote state-of-the-art industries both in space and on Earth.

Cassada began his day configuring the BioFabrication Facility, a research device that will investigate the 3-D printing of organ-like tissues in microgravity, in the Columbus laboratory module. Afterward, he was back inside Columbus watering tomato plants growing inside the Veggie space botany facility. The Veg-05 study is studying a continuous fresh-food production system for space missions. Rubio set up the new Particle Vibration experiment inside the Destiny laboratory module’s Microgravity Science Glovebox. The physics study will investigate how particles organize themselves in fluids possibly advancing manufacturing techniques and providing new insights on astrophysics.

Commander Sergey Prokopyev assisted Flight Engineer Anna Kikina during her cardiac research early Friday as she attached sensors to herself to monitor her blood circulation in microgravity. Prokopyev then worked inside the Zvezda service module checking its systems. Kikina then spent her day inside Zvezda and the Nauka multipurpose laboratory module servicing their ventilation systems. Flight Engineer Dmitri Petelin spent all day Friday replacing air purification hardware before transferring filters from the ISS Progress 82 cargo craft to the Unity module.

The space station is orbiting higher, 260 miles above Earth at its highest point and 257.1 miles at its lowest, after the ISS Progress 81 resupply ship fired its engines for nearly fifteen minutes early Friday morning. The new orbiting altitude places the station at the correct altitude for the arrival of the new ISS Progress 83 cargo craft on Feb. 11 and the unpiloted Soyuz MS-23 crew ship on Feb. 21.

NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata concluded their spacewalk at 2:26 p.m. EST after six hours and 41 minutes.

Mann and Wakata completed their major objective for today, which was to complete the construction of a mounting platform on the 1A power channel that was started during a spacewalk on Jan. 20. In addition, they relocated an articulating portable foot restraint from the P6 truss for future spacewalk tasks and deployed cables for the installation of the next pair of International Space Station Roll-Out Solar Arrays (iROSAs).

The installation was part of a series of spacewalks to augment the station’s power channels with new iROSAs. Four iROSAs have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks following their arrival later this year on SpaceX’s 28th commercial resupply services mission for NASA.

It was the 259th spacewalk in support of space station assembly, upgrades, and maintenance, the second spacewalk of 2023, and the second spacewalk for both astronauts.

Mann and Wakata are in the midst of a planned six-month science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including to the Moon through NASA’s Artemis missions.

Mission managers have given the “go” for two astronauts to exit the International Space Station on Thursday and conduct a seven-hour spacewalk. While the spacewalk preparations were under way, the rest of the Expedition 68 crew kept up its ongoing schedule of human research, botany, and physics experiments.

Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) will set their Extravehicular Mobility Units (EMUs), or spacesuits, to battery power at 8:15 a.m. EST on Thursday. After their EMUs are set to battery power, the astronauts’ spacewalk officially begins and they will exit the Quest airlock into the vacuum of space and maneuver to the starboard truss structure. Once they arrive at the Starboard-4 truss, they will complete a modification kit installation job they began on Jan. 20 to prepare the station for its next roll-out solar array.

Mann and Wakata started Wednesday readying their spacesuits and its components inside Quest. Afterward, NASA Flight Engineer Frank Rubio joined the duo and began organizing spacewalking tools and hardware before a final procedures review and a conference with specialists on the ground. Roscosmos Flight Engineer Anna Kikina also handed the spacewalking astronauts dosimeters, or radiation detectors, to attach to their spacesuits. NASA TV, on the agency’s app and website, will begin its live spacewalk coverage at 6:45 a.m. on Thursday.

Rubio began his day with NASA Flight Engineer Josh Cassada collecting and processing blood samples for spinning in a centrifuge, stowage in a science freezer, and later analysis. The pair then split up configuring advanced research hardware and an ultra-high resolution video camera. Cassada relocated two TangoLab facilities from a research rack in the Destiny laboratory module to a research rack in the Columbus laboratory module. The TangoLab cube modules enable a variety of space research from microbiology to chemistry. Cassada also watered tomato plants growing for the Veg-05 space botany study. Rubio installed the Sphere Camera-1 inside Destiny to evaluate its ultra-high resolution capabilities that may assist future space travelers with vehicle inspections, as well as Earth and space observations.

Commander Sergey Prokopyev continued testing a 3-D printer checking its performance while being controlled from a computer. Roscosmos Flight Engineer Dmitri Petelin worked throughout the day packing the ISS Progress 82 resupply ship with trash and discarded gear before replacing air filters inside the Zvezda service module. Kikina, after handing over radiation detectors in the morning, worked inside the Nauka multipurpose laboratory module testing operations with the European robotic arm.

Two Expedition 68 astronauts continue gearing up for a spacewalk scheduled for Thursday at the International Space Station. The orbital residents also kept up a host of research activities as they serviced science gear, studied human research, and explored future technologies.

The next spacewalk is scheduled to begin at 8:15 a.m. EST on Thursday to continue upgrading the space station’s power generation system. Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) will spend about seven hours in the vacuum of space completing the hardware installation job that they began on Jan. 20 during their first spacewalk. NASA TV, on the agency’s app and website, will begin live spacewalk coverage at 6:45 a.m.

Mann and Wakata started Tuesday morning organizing their tools, tethers, and other spacewalking components inside the Quest airlock ahead of Thursday’s excursion. Afterward, the duo split up as Mann worked in the Columbus laboratory module and cleaned up the BioLab facility that enables research into microbes, cells, tissue cultures, and small invertebrates. Wakata later took a robotics test on a computer measuring his performance, behavior, and cognition while living in space.

NASA Flight Engineers Josh Cassada and Frank Rubio worked throughout the day maintaining physics and biology hardware. Cassada installed the BioFabrication Facility in the Columbus lab that will be used to investigate manufacturing human organs in microgravity. Rubio worked in the Kibo laboratory module cleaning up the Life Science Glovebox following several days of advanced bone healing studies last week.

Two cosmonauts took turns today studying how future space crews might pilot spacecraft or robots on potential planetary missions. Roscosmos Commander Sergey Prokopyev and Flight Engineer Anna Kikina both wore a helmet with electrodes attached and simulated piloting techniques, such as docking a spaceship or commanding a robot on a planetary surface, on a computer.

Flight Engineer Dmitri Petelin spent his morning investigating fluids exposed to magnetic and electric fields in microgravity. During the afternoon, he moved on to orbital lab maintenance and worked on an oxygen generator before servicing water and drainage valves.

The remotely-controlled Canadarm2 robotic arm jettisoned flight support equipment during the day that was delivered aboard the SpaceX Dragon cargo ship on Nov. 27, 2022, toward Earth’s atmosphere. The flight hardware secured a pair of roll-out solar arrays inside Dragon’s trunk during its ascent to orbit and rendezvous with the space station. The jettisoned support equipment drifted safely away from the station and will eventually harmlessly burn up in the atmosphere with no chance for recontacting the space station.

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.
