Ax-4 Mission Update: Flight Day #12

July 6, 2025
Ax-4 Commander Peggy Whitson uses her years of experience capturing photos in microgravity to document the mission aboard the International Space Station.

HIGHLIGHTS
Now past the halfway point of their mission aboard the International Space Station, the Axiom Mission 4 (Ax-4) crew’s momentum remains strong, and their impact continues to grow with each passing day on orbit. Commander Peggy Whitson, Pilot Shubhanshu “Shux” Shukla, and Mission Specialists Sławosz “Suave” Uznański-Wiśniewski and Tibor Kapu have spent the last ten days committed to their busy schedule of scientific research, technology demonstrations, and global outreach.

RESEARCH
Shux continued investigating how microgravity accelerates muscle atrophy by performing microscopy and collecting cellular samples for the myogenesis study. This work is helpful for uncovering how muscle tissue deteriorates in space and for developing strategies to protect astronaut health during extended missions.

Shux also redeployed a culture bag for the Space Micro Algae experiment. With the potential to produce food, oxygen, and even biofuel, microalgae could become essential companions on future missions to the Moon and Mars.

Meanwhile, Tibor spent time observing the Fruit Fly DNA Repair study, which will investigate how space radiation affects genetic integrity. By studying how fruit fly DNA responds to radiation experienced during Ax-4, scientists hope to develop strategies to protect human DNA in space.

The crew contributed to the Wireless Acoustics project, testing a wearable acoustic monitor designed to measure sound levels aboard the space station. This commercially available device is being evaluated for comfort, usability, and accuracy, with its data compared to on board traditional fixed sound meters.

A crewmember underwent an ultrasound scan to track changes in cardiovascular and balance systems for the Telemetric Health AI study. This project aims to enable real-time health monitoring and predictive healthcare on orbit and on Earth.

The crew participated in the Acquired Equivalence Test, a cognitive experiment designed to explore how microgravity affects associative learning. The results could shed light on how the brain adapts to the unique demands of space.

Finally, the crew is exploring the potential of nanomaterials through the Mxene in LEO study. These ultra-thin, 2D inorganic compounds are being tested in six biometric sensor prototypes to evaluate their performance in space. The findings could lead to the next generation of wearable health tech, supporting astronauts on missions and transforming medical monitoring here on Earth.

From muscle cells to nanomaterials, each of these experiments brings us one step closer to safer, smarter, and more sustainable space exploration.

OUTREACH
Peggy and Suave teamed up for a live mission update. During the conversation, Suave added a personal touch by sharing a special food item he's been enjoying aboard the station — one that brings a comforting reminder of home. Tune in to see what it is and catch the latest insights from life on orbit!

Tomorrow at 6:00 a.m. CT/1:00 p.m. CEST, Suave will speak with members of the Polish media about the importance of the Ax-4 mission and his role in advancing Poland’s scientific research goals. His contributions aboard the space station represent a proud moment for his nation’s growing presence in space. Click here to watch the event live.

As a leader in the commercial space industry, Texas continues to shape the future of space exploration. Axiom Space is bringing together key stakeholders from the Texas state government, Texas Space Commission, and Texas Aerospace Research and Space Economy Consortium to speak with the Peggy tomorrow from the space station. Their discussion will focus on the significance of commercial space, the strength of Texas leadership, and the importance of workforce development in supporting the industry's rapid growth.
