Scientific hardware installations and biomedical monitoring topped the research schedule aboard the International Space Station on Wednesday. The Expedition 74 crew members also adjusted a spacesuit to prepare for a spacewalk and explored space physics to round out their day.

A series of shoebox-sized CubeSats will soon be deployed outside the Kibo laboratory module into Earth orbit for public and private research. One of the satellites, Hokushin-1 CubeSat, will test space technologies such as radio frequency, propulsion, and solar arrays. NASA flight engineer Jack Hathaway finished installing a small satellite orbital deployer, packed with the CubeSats, into Kibo’s airlock where it will soon be placed in the vacuum of space and grappled by the Japanese robotic arm. The deployer will be maneuvered with the robotic arm and positioned away from the orbital outpost to safely release the tiny satellites into Earth orbit.

Onboard the orbital outpost are a variety of research freezers—large, small, portable, and permanent—that house and preserve station research samples for analysis both on Earth and in space. One of them, a smaller glovebox freezer, is being installed inside Kibo’s Life Science Glovebox (LSG) by NASA flight engineer Jessica Meir for upcoming experiment operations. The freezer’s location inside the LSG allows the samples to be stowed and frozen immediately after processing to prevent degradation and preserve integrity during sensitive biology research.

Meir also assisted flight engineer Sophie Adenot of ESA (European Space Agency) as she set up wearable devices for a pair of biomedical tests on Wednesday. Adenot first measured her blood pressure to calibrate the PhysioTool technology demonstration gear. Next, she wore head and body sensors that measured her brain oxygen and blood flow levels as she performed cognitive and mental tasks on a computer. Researchers are testing the portable device onboard the station to potentially monitor crew health on missions to the Moon, Mars, and beyond.

Meir also had time to help NASA flight engineer Chris Williams pack cargo inside a SpaceX Dragon cargo spacecraft that will undock from the Harmony module’s forward port and soon return to Earth. Williams then maneuvered into the Quest airlock and adjusted a spacesuit’s legs, arms, and helmet, then ensured the suit’s switches and valves were correctly configured ahead of an upcoming spacewalk.

On May 27, during routine operations of the International Space Station’s Canadarm2, the system demonstrated an elevated motor current in a wrist joint and arm motion did not occur as expected. NASA worked alongside CSA (Canadian Space Agency) to understand the issue and determined a spacewalk will be required to replace the joint using a spare already aboard the orbital complex. The Canadarm2, which is designed to be repaired in orbit, is in a safe configuration and standard operations using the arm have been paused. In the coming weeks, NASA will host a news conference to discuss the repair and preview the planned Tuesday, June 30 spacewalk. NASA will share more on the spacewalkers closer to the activity.

Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev joined each other and explored space physics in the Zvezda service module. The duo observed how two different sized spheres drift freely in microgravity with no pushing movement from the crew. Results may lead to the design of newer space tools, improved robotics, and a deeper understanding of crew motion. Roscosmos flight engineer Andreu Fedyaev focused primarily on maintenance testing computer operations, cleaning ventilation systems, and transferring water between station tanks.

Finally, the space station is orbiting higher today after the Progress 95 cargo spacecraft fired its thrusters for over eight minutes early Wednesday raising its altitude by 1.9 miles. This adjusts the orbital outpost’s altitude ahead of the launch and docking of the Soyuz MS-29 crew spacecraft planned for mid-July.

Microbiology and human research were the main scientific focus aboard the International Space Station on Tuesday to protect health on and off the Earth. The Expedition 74 crew members also worked on advanced research hardware and sent down a congratulatory message to the Artemis III crew, who were named during an announcement from the Johnson Space Center in Houston.

Some common bacteria have shown an increased resistance to antibiotics in the space environment potentially affecting an astronaut’s ability to fight an infection. Flight engineers Jack Hathway of NASA and Sophie Adenot of ESA (European Space Agency) explored the antibiotic-resistant organisms inside the Kibo laboratory module’s Life Science Glovebox and the Harmony module’s maintenance work area by processing the microbial samples and preparing them for DNA extraction and analysis. Doctors will use the data to understand how microbes adapt to microgravity possibly informing countermeasures to reduce the risk to astronaut health and protect patients on Earth.

NASA flight engineers Jessica Meir and Chris Williams partnered together loading a CubeSat-packed small satellite orbital deployer into Kibo’s airlock that will soon be placed into the vacuum of space. The Japanese robotic arm will grapple the deployer and point it away from the orbital outpost where it will safely deploy the shoebox-sized satellites into Earth orbit. A series of tiny satellites will be released for public and private research, including the Hokushin-1 CubeSat that will test space technologies such as radio frequency, propulsion, and solar arrays.

Roscosmos cosmonauts Sergey Kud-Sverchkov and Andrey Fedyaev worked on a pair of different investigations on Tuesday to continuously monitor how weightlessness affects the human body. Kud-Sverchkov, the orbital outpost’s commander, strapped an acoustic sensor around his neck that recorded his rapid exhalation to learn how living in space affects the respiratory system. Fedyaev wore a set of cuffs attached to his arms, wrist, and fingers measuring his blood pressure for a microgravity cardiac experiment. Roscosmos flight engineer Sergei Mikaev was back on artificial intelligence research studying new tools to boost crew efficiency and communications aboard a spacecraft.

Four of the station’s astronauts also sent down a message congratulating the four new Artemis III crew members commander Randy Bresnik of NASA, pilot Luca Parmitano of ESA, and NASA mission specialists Frank Rubio and Andre Douglas. The four flight engineers each spoke a few inspiring words with Meir stating, “Congratulations, Artemis III and godspeed on the journey ahead.” Watch the crew message on @Space_Station X.

Expedition 74 began the week bioprinting human cartilage tissue and harvesting alfalfa plants aboard the International Space Station to advance health and promote self-sustainable space crews. The orbital residents also retrieved materials exposed to the external space environment and conducted their own ultrasound vein scans to continuously learn how living in space affects physics and biology.

NASA flight engineer Jessica Meir opened up the Kibo laboratory module’s Life Science Glovebox on Monday and set up a bioprinter to produce viable cartilage tissues aboard the orbiting laboratory. NASA flight engineer Chris Williams assisted Meir collecting the frozen cartilage samples for thawing then mixing the living cells with a gel-like bioink for placement in a printing cartridge. The biotechnology study tests the manufacturing of cartilage in weightlessness to increase its stability for printing on demand implants using a patient’s own cells to treat a range of health conditions.

Earlier, Williams began his shift with NASA flight engineer Jack Hathaway harvesting alfalfa plants inside the Columbus laboratory module’s Veggie facility. The astronauts collected the plants and roots for photographing, placed the botanical samples inside foil, then stowed them inside a science freezer for later analysis for the Veg-06 study. Insights may lead to the development of advanced methods to grow plants for food on future space missions.

Afterward, Hathaway scanned Williams neck, shoulder, and leg veins using the Ultrasound 3 biomedical device as doctors on the ground monitored in real time. Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev also took turns scanning each other’s veins with the Ultrasound 3. The ultrasound imagery will help researchers protect crew members from space-caused blood clots.

Flight engineer Sophie Adenot of ESA (European Space Agency) and Meir joined each other during the first half of their shift retrieving containers of samples from Kibo’s airlock that were placed outside the orbital outpost for a materials exposure test. The samples included radiation shields, crew suit fabrics, optical fibers, and more to help engineers build robust technologies that can survive harsh environments both on Earth and in space.

Sergey Kud-Sverchkov and Sergei Mikaev, the orbiting lab’s commander and flight engineer, spent the majority of their shift inspecting and servicing the Zvezda service module’s treadmill. The space station’s other treadmill, COLBERT, is located in the Tranquility module.

Roscosmos flight engineer Andrey Fedyaev spent the first half of his shift locating and identifying computer components and video gear in the Zarya module to update the station’s inventory management system. Fedyaev wrapped up his day studying using artificial intelligence tools to boost crew efficiency and communications.

NASA Provides Update on Space Station Leak

NASA Provides Update on Space Station Leak

The station pictured from the SpaceX Crew Dragon
The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a flyaround on Nov. 8, 2021.

The Zvezda service module’s transfer tunnel, known as the PrK, on the International Space Station has experienced cracks since 2019 that have resulted in small atmosphere leaks and prompted ongoing monitoring and repair efforts by Roscosmos. NASA and Roscosmos have worked together to identify the root cause while Roscosmos has been applying leak mitigation measures, including temporary and permanent sealants.

The week of June 1, during Progress 95 spacecraft cargo operations, Roscosmos noted an increase of the previous leak rate to two pounds per day and identified new suspected leak areas in the PrK. Following this observation, Roscosmos made the decision to begin work toward a more extensive inspection and structural repair effort Friday morning. This revised approach involved cutting a bracket to better access an area identified as a possible leak source for further inspection, using a method that could have resulted in elevated risk to the structure in the area. In response, NASA directed the four SpaceX Crew-12 members and NASA astronaut Chris Williams, who flew to station aboard the Soyuz MS-28 spacecraft, to take a heightened safety posture, known as a safe haven, inside the SpaceX Dragon spacecraft during the procedure.

Later Friday morning, Roscosmos paused and did not perform the structural repair work in favor of conducting additional measurements and data assessments, which included inspection of suspected areas of interest and review of areas where sealant was previously applied. NASA strongly supported that decision, and as a result, following that decision, Crew-12 and Williams ended their safe haven activities and returned to normal operations aboard the orbiting laboratory.

NASA will continue to work with our Russian counterparts, along with the rest of the international partners that support the space station, to assess and ensure a resolution to this matter.

3D bioprinting and stem cell research were the main research topics aboard the International Space Station on Thursday. The Expedition 74 crew members also photographed growing plants and lab windows for inspection while continuing to pack a U.S. cargo spacecraft.

Flight engineers Jessica Meir of NASA and Sophie Adenot of ESA (European Space Agency) joined each other at the beginning of their shift and tested the operation of a 3D bioprinter inside the Kibo laboratory module. Adenot first mixed cartilage cell samples with bio-ink then handed them to over Meir for insertion inside a bioprinter cartridge to print human tissue. The biotechnology device may advance regenerative medicine leading to on-demand, personalized medical implants using the patient’s own cells. Later, Meir nourished blood stem cell samples inside Kibo’s Life Science Glovebox at the end of her shift for another investigation. The cell samples are growing inside a research incubator to help doctors learn how to manufacture and commercialize space-designed therapies for a variety of blood cancers and immune diseases.

Adenot later partnered with NASA flight engineer Jack Hathaway packing cargo inside a SpaceX Dragon cargo spacecraft as it nears the end of its stay docked to the Harmony module’s forward. Hathaway spent the first half of his shift tending plants growing for a pair of botany studies to promote space agriculture and self-sustaining space missions. He began watering and photographing alfalfa plants growing inside the Columbus laboratory module’s Veggie facility for the Veg-06 study. Next, he photographed microgreens, or plants with higher vitamin and mineral content than mature leaves, growing inside specialized chambers in the Destiny laboratory module. Hathaway wrapped up his shift downlinking data to Earth that documents how space radiation affects semiconductor transistors.

NASA flight engineer Chris Williams primarily spent his day on hardware maintenance beginning inside Kibo and cleaning dust and debris collected in the module’s ventilation system. Williams then moved over to the Columbus lab and relocated parts and components associated with the European Enhanced Exploration Exercise Device. Next, he collected space radiation data recorded on the Lumina device before inspecting tethers that secure spacewalkers on the space station.

The station’s three cosmonauts, Sergey Kud-Sverchkov, Sergei Mikaev, and Andrey Fedyaev, coordinated throughout Thursday on inspections in the orbital outpost’s Roscosmos segment. The trio partnered together in the Zvezda service module inspecting its hull and photographing windows in the Zvezda and Poisk modules.
