Brand new science is underway at the International Space Station with two new crews and a cargo ship arriving in March to replenish the Expedition 70 crew. The orbital residents explored a variety of space health technologies and more on Thursday.

NASA Flight Engineer Tracy C. Dyson, who is on her third spaceflight, worked in the Columbus laboratory module swapping hardware for a new experiment seeking to demonstrate 3D printing of antimicrobial parts in space. The investigation named Copper Anti-Microbial Prints, or CAMP, is examining the effectiveness of producing medical devices on-demand and how microgravity affects their anti-microbial properties.

NASA Flight Engineer Loral O’Hara processed messenger RNA (mRNA) and protein samples in the Life Science Glovebox for an experiment, recently delivered aboard the SpaceX Dragon cargo craft, to investigate nanomaterials that mimic DNA. The study, called DNA Nano Therapeutics-Demo 2, is exploring space-manufactured DNA nanomaterials in order to produce therapeutics that may benefit travelers in space and humans on Earth.

One space-caused phenomenon that concerns researchers is the headward fluid shifts that occur in astronauts. Once in space, a crewmember’s body fluids begin to flow upward affecting their eye structure and vision. Another more visible result is commonly called “puffy face.” NASA astronauts Matthew Dominick and Jeanette Epps partnered together Thursday afternoon and tested a specialized thigh cuff that may counteract these fluid shifts. Dominick wore the cuff on his leg and took ultrasound scans with assistance from Epps and doctors on Earth. Results may also impact treatments for fluid accumulations caused by Earth-bound conditions.

NASA astronaut Mike Barratt spent his day on space biology participating in the CIPHER suite of 14 human research studies. He participated in a series of cognition and robotics tests then collected his blood and urine samples for analysis. Results from the expansive investigation may provide scientists insights into the physiological and psychological effects of living in space long-term.

Roscosmos cosmonaut Oleg Novitskiy and Belarus spaceflight participant Marina Vasilevskaya, along with Dyson, are in their first week aboard the orbital outpost. Novitskiy and Vasilevskaya will return to Earth on April 6 bringing home O’Hara who has been aboard the station since Sept. 15. Dyson will stay in space until early fall.

Novitskiy joined his fellow cosmonauts Oleg Kononenko and Nikolai Chub and replaced hardware components inside the Soyuz MS-24 and MS-25 crew ships. Chub then teamed up with new cosmonaut Alexander Grebenkin and studied blood flow and cell respiration for a Roscosmos life science study. Vasilevskaya, with assistance from Chub, recorded her heart rate and tested a specialized suit’s theorized ability to help a crew member readjust to Earth’s gravity.

Ten crewmates now reside aboard the International Space Station after the arrival of the Soyuz MS-25 crew ship on Monday. They will live and work together the next several days before returning to a seven-member crew again and beginning the Expedition 71 mission in early April.

NASA astronaut Tracy C. Dyson arrived at the orbital lab on Monday with Roscosmos cosmonaut Oleg Novitskiy and Belarus spaceflight participant Marina Vasilevskaya. Dyson will stay in space for about six months as a member of the station crew. Novitskiy and Vasilevskaya will return to Earth with NASA astronaut Loral O’Hara on April 6.

The trio will return to Earth inside the Soyuz MS-24 spacecraft that has been docked to the Rassvet module since Sept. 15, 2023. O’Hara will have lived and worked on the orbital outpost for six-and-a-half months having conducted advanced space research and one spacewalk.

Dyson and her two Soyuz crewmates will be spending the next few days familiarizing themselves with space station systems. Next, they will turn their attention to a host of science and educational activities before returning home while Dyson stays in space until later this year.

Station flight engineers Matthew Dominick, Mike Barratt, Jeanette Epps, and Alexander Grebenkin are in the first month of their mission having arrived at the station on March 5 aboard the SpaceX Dragon Endeavour. They will stay in space until mid-summer researching a wide variety of phenomena including neurodegenerative diseases, the effects of microgravity and radiation on plants, and preventing space-caused fluid shifts in astronauts.

Cosmonauts Oleg Kononenko and Nikolai Chub are due to stay in space for just over a year helping doctors understand how living long-term in microgravity affects the human body. The duo will depart the space station inside the Soyuz MS-25 spacecraft and bring home Tracy Dyson in early fall.

While the International Space Station was traveling more than 262 miles over the South Atlantic Ocean, a SpaceX Dragon cargo spacecraft autonomously docked to station’s Harmony module at 7:19 a.m. EDT, with NASA astronauts Loral O’Hara and Michael Barratt monitoring operations from the station.

The Dragon launched on SpaceX’s 30th contracted commercial resupply mission for NASA at 4:55 p.m. EDT, March 21, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. After Dragon spends about one month attached to the space station, the spacecraft will return to Earth with cargo and research.

Among the science experiments Dragon is delivering to the space station are:

Monitoring Sea Ice Thickness and Wave Height

(Nanoracks-Killick-1) is a CubeSat that measures sea ice parameters using Global Navigation Satellite System (GNSS) reflectometry or reflected signals. This monitoring system could contribute to a better understanding of important ocean phenomena and improved weather and climate models.

New Sensors for ASTROBEE

The Multi-resolution Scanner (MRS) Payload for the Astrobee (Multi-Resolution Scanning) tests a new set of sensors to support automated 3D sensing, mapping, and situational awareness functions. These systems could support future Gateway and Lunar surface missions by providing automated defect detection, automated and remote maintenance, and autonomous vehicle operations.

Improving Efficiency of Quantum-Dot Solar Cells

The Nano Particle Haloing Suspension payload tests the controlled assembly of nanoparticles in a liquid solution. A process called nanoparticle haloing uses charged nanoparticles to enable precise particle arrangements that improve the efficiency of quantum-dot synthesized solar cells. Conducting these processes in microgravity provides insight into the relationship between shape, charge, concentration, and interaction of particles.

Observing Photosynthesis in Space

Advanced Plant Experiment-09 (APEX-09), also known as C4 Photosynthesis in Space, observes carbon dioxide capture and mechanisms in two types of grasses. Researchers hope to learn more about photosynthesis and plant metabolism changes overall in space. Knowledge gained could support development of bioregenerative life support systems on future missions.

These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon through NASA’s Artemis missions and eventually Mars.

xpedition 70 Flight Engineer and NASA astronaut Jeanette Epps prepares tubes to collect samples from the crew for the Immunity Assay investigation.
Expedition 70 Flight Engineer and NASA astronaut Jeanette Epps prepares tubes to collect samples from the crew for the Immunity Assay investigation.

One crew and one cargo spacecraft on two different continents are counting down to launch as the seven orbital residents aboard the International Space Station spent Wednesday exploring how space affects the immune system, carrying out robotics activities, and connecting with students on Earth.

Three crew members are gearing up to launch from the Baikonur Cosmodrome in Kazakhstan on Thursday, March 21. NASA astronaut Tracy Dyson, cosmonaut Oleg Novitsky, and Flight Engineer Marina Vasilevskaya of Belarus will lift off aboard the Soyuz MS-25 spacecraft at 9:21 a.m. EDT and take a short ride to the station, docking only a few hours later at 12:39 p.m., joining the Expedition 70 crew in microgravity. This will be Dyson’s third trip to the orbital complex, where she will spend six months conducting research in low Earth orbit.

Only a few hours after the crew arrives, NASA’s SpaceX 30th commercial resupply mission will lift off from Space Launch Complex 40 in Florida. The Dragon cargo craft, scheduled to launch at 4:55 p.m. on Thursday, will carry an array of new science and technology investigations, as well as food and supplies for the crew. Dragon will orbit Earth before autonomously docking to the zenith port of the Harmony module at 7:30 a.m. Saturday, March 23.

In microgravity, the crew split up duties on Wednesday as they prepare for the upcoming station traffic. In the morning, Flight Engineer Matthew Dominick of NASA collected samples for the Immunity Assay investigation. Afterward, Flight Engineer Jeanette Epps of NASA processed the samples for the experiment. Immunity Assay looks at the impact of spaceflight on cellular immune functions in blood samples, tests that could only previously be conducted on Earth. With new tech, processing samples inflight helps researchers gain a better understanding of astronauts’ immune changes during long-duration space missions.

Dominick and Epps later teamed up to reconfigure some of the cameras aboard station that the crew uses to take photos of research, Earth, and more.

In the Japanese Experiment Module, Flight Engineer Michael Barratt of NASA powered on the free-flying Astrobee robots and conducted a Zero Robotics tech demonstration. Zero Robotics allows students on Earth to write software to control Astrobee, inspiring the next generation of scientists, engineers, and explorers.

Afterward, Barratt teamed up with Flight Engineer Loral O’Hara of NASA to conduct an ISS Ham Radio session with a school in Greece. During the session, Barratt and O’Hara answered questions from students about living and working in space.

In the Nauka module, Flight Engineer Nikolai Chub replaced air ventilation filters, then moved on to collect and process water samples from the Roscosmos water processing system. Flight Engineer Alexander Grebenkin practiced his piloting techniques during a Pilot-T session, while Commander Oleg Kononenko prepped for Soyuz’s arrival as he will be on deck to monitor the autonomous docking of the spacecraft.

Equipment installs, health investigations, and training occupied the schedule aboard the International Space Station on Tuesday as the seven orbital residents near the arrival of three crew members and a cargo delivery.

NASA’s SpaceX 30th commercial resupply mission to the station is scheduled for launch at 4:55 p.m. EDT Thursday, March 21 from Space Launch Complex 40 in Florida. The Dragon cargo craft will deliver food, supplies, and new science investigations to the crew, including a set of sensors for the free-flying Astrobee robots and a new botany experiment to examine how two types of grass capture carbon dioxide from the atmosphere. Dragon will autonomously dock to the zenith port of the Harmony module at 7:30 a.m. Saturday, March 23.

Ahead of Dragon’s liftoff, three crew members—NASA astronaut Tracy Dyson, cosmonaut Oleg Novitsky, and Flight Engineer Marina Vasilevskaya of Belarus—will launch from the Baikonur Cosmodrome in Kazakhstan at 9:21 a.m. Thursday, March 21. The international crew will take a short ride to the station, docking only a few hours later at 12:39 p.m., before opening the hatch and joining the Expedition 70 crew in microgravity. Dyson will begin a six-month microgravity research mission once aboard, while Novitsky and Vasilevskaya will spend 12 days on station before departing back to Earth with NASA astronaut Loral O’Hara.

Aboard station, the crew is back to work following a few days off-duty. Throughout the day, O’Hara and two of her NASA crewmates, Michael Barratt and Matthew Dominick, completed a round of SpaceX Dragon rendezvous training ahead of Dragon’s cargo arrival.

In the morning, Barratt assisted O’Hara with a blood sample collection for the CIPHER investigation. O’Hara then moved on to complete additional CIPHER tasks, including a Robotics On-Board Trainer research session to assess her cognitive performance and spatial cognition changes while conducting robotics maneuvers such as grappling and docking a spacecraft. CIPHER, or Complement of Integrated Protocols for Human Exploration Research, is an all-encompassing, total-body approach that examines how humans adapt to spaceflight.

Later on, Barratt installed the Space Automated Bioproducts Lab for future life, physical, and material science investigations. Dominick installed a new humidifier in the Cell Biology Experiment Facility for upcoming Space Organogenesis research. This investigation uses the microgravity environment to enable 3D cell growth to promote regenerative technology that could someday help people in need of transplants on Earth.

NASA Flight Engineer Jeanette Epps spent the morning collecting biological samples for the Standard Measures investigation then moved into the Destiny laboratory module to set up the Robotic Arm Repair Satellite (RSat). RSat, installed in the Microgravity Science Glovebox, explores how CubeSats fitted with a robotic arm might be used to repair larger satellites.

Cosmonauts Alexander Grebenkin and Nikolai Chub spent the day working with the Roscosmos water processing system, running a distillation cycle and collecting samples. Commander Oleg Kononenko of Roscosmos donned a belt packed with sensors to monitor blood circulation in microgravity then practiced his piloting techniques during a Pilot-T session.
