Eye checks and “anti-gravity” suits were the main human research topics for the Expedition 70 crew on Wednesday. The International Space Station residents also worked on standard maintenance tasks while getting ready for the next Commercial Crew swap.

Doctors are constantly monitoring astronauts’ health to ensure long-term mission success and ease their return to Earth’s gravity after months or years in space. Vision is a critical parameter as researchers explore space-caused pressure on the eyes due to fluids shifting toward the head. The same fluid shifts quickly reverse when an astronaut reenters Earth’s atmosphere causing blood pressure and stability issues. Doctors are studying methods to offset these symptoms and reduce the time it takes for crews to adapt to gravity.

NASA Flight Engineer Loral O’Hara had her optical nerve, retina, and cornea scanned on Wednesday using standard medical imaging hardware. JAXA (Japan Aerospace Exploration Agency) Flight Engineer Satoshi Furukawa led the eye exams operating the optical gear in the Harmony module with assistance from doctors and technicians on the ground.

Earlier in the day, O’Hara wore a sensor-packed vest and headband, the Bio-Monitor gear from the Canadian Space Agency, being evaluated for their ability to comfortably monitor an astronaut’s health data. Furukawa continued setting up biology hardware for upcoming research inside the Kibo laboratory module.

Two cosmonauts, Nikolai Chub and Konstantin Borisov, tried on the lower body negative pressure suit again in the middle of the week exploring its potential to decrease fluid pressure in the head triggered by weightlessness. Doctors theorize the downward fluid shifts may help maintain a crew member’s heart rate and blood pressure when returning to Earth.

Meanwhile, astronauts Jasmin Moghbeli from NASA and Andreas Mogensen from ESA (European Space Agency) joined forces and spent the day inside the Quest airlock replacing advanced air conditioning equipment. The duo swapped hoses, seals, and a heat exchanger on the Common Cabin Air Assembly, a life support device that circulates, cools, and dehumidifies the station’s air.

Moghbeli and Mogensen, Commander and Pilot of the SpaceX Crew-7 mission, also continued packing gear for their return to Earth inside the SpaceX Dragon “Endurance” spacecraft. The duo along with Furukawa and Borisov are scheduled to depart the station ending their mission about one week after the SpaceX Crew-8 mission arrives.

Crew-8, led by Commander Matthew Dominick with Pilot Michael Barratt and Mission Specialists Jeanette Epps and Alexander Grebenkin, have been given the go to launch to the station at 12:04 a.m. EST on Friday aboard the SpaceX Dragon “Endeavour” spacecraft. The Commercial Crew quartet will take an automated ride aboard Dragon for a docking to Harmony’s forward port at 7 a.m. on Saturday.

NASA and SpaceX are also targeting no earlier than mid-March for launch of the company’s 30th commercial resupply services mission to the International Space Station. Liftoff of the SpaceX Falcon 9 rocket and Dragon cargo spacecraft is scheduled from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

During the NASA Administrator’s Briefing from Kennedy Space Center today, NASA’s International Space Station Program Manager Joel Montalbano discussed the upcoming crew and cargo missions.

The Expedition 70 crew focused mainly on operational maintenance activities throughout Tuesday. The International Space Station residents also continued their exercise research among a host of other ongoing science experiments.

Airlock activities filled the day for NASA Flight Engineers Loral O’Hara and Jasmin Moghbeli in the U.S. segment of the orbital lab. The duo started the day in the Tranquility module and finalized reconfiguring the NanoRacks Bishop airlock following a week of experimental robotic arm activities. Afterward, the NASA pair moved into the Quest airlock and serviced a pair of spacesuits then prepared Quest for upcoming advanced air conditioning work.

Commander Andreas Mogensen from ESA (European Space Agency) worked inside the Columbus laboratory module during the morning swapping out life support gear. Later, he set up the Lumina radiation detection experiment hardware in Columbus that measures in real time the fluctuating radiation environment aboard the space station.

JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa had a busy schedule as he worked on biology and robotics research all day. Furukawa first swapped sensors and checked vents on the Cell Biology Experiment Facility located in the Kibo laboratory module. Next, Furukawa checked out the performance of a free-flying camera robot inside Kibo.

Finally, Furukawa spent the rest of Tuesday participating in the CIPHER experiment, a suite of 14 human research studies to understand the effects of weightlessness on the body. He began with deadlift exercises on the advanced resistive exercise device for one portion of the study. Next, he wore the Bio-Monitor vest and headband recording his physiological data then calibrated breathing gear. CIPHER is providing doctors vital insights that may help keep crews safe and healthy on longer term missions to the Moon, Mars, and beyond.

All three astronauts and Roscosmos Flight Engineer Konstantin Borisov also spent an hour each throughout the day packing for their upcoming departure and return to Earth. The quartet will undock from the Harmony module’s space-facing port aboard the SpaceX Dragon Endurance spacecraft a week after the SpaceX Crew-8 members arrive. Crew-8 is due to launch at 12:04 a.m. EST on Friday aboard the SpaceX Dragon Endeavour spacecraft and dock to Harmony’s forward port on Saturday at 7 a.m.

Veteran cosmonaut Oleg Kononenko and Flight Engineer Nikolai Chub spent most of the day installing cargo containers inside the Zarya module. Kononenko later jogged on a treadmill while attached to electrodes and sensors for a regularly scheduled fitness assessment at the end of the day. Daily exercise aboard the station is necessary for crews to maintain bone and muscle health due to the lack of gravity. Borisov also worked on computer and ventilation maintenance in the station’s Roscosmos segment.

Human research, space physics, and airlock operations started the week for the Expedition 70 crew aboard the International Space Station. Back on Earth, four Commercial Crew members are counting down to their launch aboard the SpaceX Dragon spacecraft to the orbital outpost.

Exercising daily in space is critical to maintain crew health due to the effects of living long-term in weightlessness. Astronauts work out on specialized exercise gear designed specifically for the microgravity environment including a treadmill, an exercise cycle, and the advanced resistive exercise device. Doctors frequently monitor these exercise sessions while crew members are attached to sensors, electrodes, and breathing gear.

Flight Engineer Jasmin Moghbeli of NASA and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) took turns pedaling on the exercise cycle Monday morning for a workout study. The duo exercised inside the Destiny laboratory module for the regularly scheduled aerobics and fitness test that measures heart and breathing rate.

Moghbeli then moved on and joined NASA Flight Engineer Loral O’Hara to work on the NanoRacks Bishop airlock inside the Tranquility module. Both astronauts spent Monday afternoon reconfiguring Bishop after it was reattached to Tranquility following a week of experimental GITAI-S2 robotics tests. The autonomous robotic arm demonstration explores using automated robots to build habitats and spacecraft on future lunar and planetary missions. Furukawa also assisted with the airlock work after he inspected hatches in the U.S. segment of the space station.

Physics was also on the research schedule as O’Hara and Commander Andreas Mogensen from ESA (European Space Agency) serviced samples and hardware for a pair of different experiments. O’Hara swapped optic fiber samples inside the Microgravity Science Glovebox for an investigation exploring how to manufacture fiber optic cables superior to those produced on Earth. Mogensen replaced components inside the Combustion Integrated Rack for a space fire safety experiment.

Roscosmos Flight Engineer Nikolai Chub had a fitness evaluation on Monday as he jogged on a treadmill with electrodes attached to his chest measuring his heart rate. Cosmonauts Oleg Kononenko and Konstantin Borisov tried on a suit being tested for its ability to help crew members adjust to Earth’s gravity after living for months or years in space.

Meanwhile, the space station is orbiting higher after the docked Progress 87 resupply ship fired its engines for over 17 minutes on Friday. The orbital reboost positions the station for next month’s launch of the Soyuz MS-25 crew ship and the departure of the Soyuz MS-24 crew ship.

Back on Earth, four Commercial Crew members representing the SpaceX Crew-8 mission are at the Kennedy Space Center in Florida preparing for their launch aboard the SpaceX Dragon Endeavour spacecraft. Commander Matt Dominick, Pilot Mike Barratt, and Mission Specialists Jeanette Epps and Alexander Grebenkin will lift off aboard Dragon at 12:04 a.m. EST on Friday. They will dock to the Harmony module’s forward port at 6 a.m. on Saturday beginning a six-month space research mission on the orbital lab.
