The view was still extraordinary, but the work, even more so for the Axiom-4 (Ax-4) crew. With Earth turning silently below them, the crew, including India’s Group Captain Shubhanshu Shukla (Shux) spent their third day aboard the International Space Station (ISS) studying cancer, cognition, microalgae , the building blocks of long-term spaceflight, and more.
The experiments being carried out by Shux and other crew members are part of the more than 60 scientific investigations from 31 countries, including India, the US, Poland, Hungary, Brazil, Nigeria, and Saudi Arabia. After all, Ax-4 is the most research-intensive private mission to the ISS to date.
Shux, who had kicked off his research activity with a muscle loss study the previous day, was hard at work on a project that’s microscopic in size but potentially massive in impact. He deployed sample bags and imaging tools for a space microalgae experiment, studying how these tiny organisms fare in orbit.
Rich in nutrients and capable of recycling carbon dioxide, microalgae could become a key part of long-duration space missions — a source of food, oxygen and life support rolled into one. He was also part of, along with other AX-4 crew, the “Neuro Motion VR” study, which uses virtual reality headsets and brain-monitoring technology (fNIRS) to observe how astronauts’ cognitive and motor functions respond to spaceflight.
“Alongside that, they collected data for ‘ Telemetric Health AI ’, a project that merges biometric tracking with AI analytics to better understand how spaceflight affects the cardiovascular and balance systems. These studies aren’t just academic. They’re building the foundations for safe, extended human missions into deep space,” Axiom Space said.
Commander Peggy Whitson , a seasoned astronaut on her fourth spaceflight, devoted much of the day to the Cancer in LEO (low-Earth orbit) investigation. Working with the Sanford Stem Cell Institute, she captured imaging samples of cancer cells exposed to microgravity. The stress of space may change the way these cells behave, potentially offering clues to tackling aggressive, metastatic cancers back on Earth.
Her camera didn’t stop there. Whitson also photographed student-designed science experiments and artwork for the Saudi Space Agency’s Microgravity Challenge — a competition that drew over 80,000 entries from young innovators across the Arab world. With submissions ranging from sustainable farming ideas to space-inspired art, it’s an example of how missions like Ax-4 can inspire the next generation of scientists, engineers and dreamers.
Mission specialist Suave (Slawosz Uznanski) focused his attention on the microfluidic design experiment to observe how fluids behave in low gravity. The end goal? Developing microfluidic devices that test drug stability and quality — a vital step toward bringing autonomous health care to future space travellers.
And yet, research isn’t the only focus. The crew also reached out to Earth. Tibor Kapu shared a live conversation with Hungarian PM Viktor Orbán, while Whitson and Suave spoke with Axiom Space Chief Scientist Dr Lucie Low about protecting astronauts from space radiation — a challenge no future mission can ignore.
