Astronaut-Physician Anil Menon Highlights Space Station Medical Research

India-West News Desk

HOUSTON, TX – NASA astronaut Anil Menon has shared an inside look at his first days aboard the International Space Station (ISS), highlighting a medical experiment that could transform healthcare not only for future missions to the Moon and Mars but also for emergency response on Earth.

In a social media post on July 17, Menon described spending the day inside the station’s Life Sciences Glovebox alongside NASA astronaut Jessica Meir, who was leading the IVGEN Mini experiment. The project aims to produce sterile, medical grade intravenous (IV) saline solution using the ISS’s drinking water.

“She’s running IVGEN Mini, our IV fluid generation experiment, and the idea is simple to say and hard to do: turn the station’s drinking water into sterile, medical grade IV fluid,” Menon wrote.

The technology addresses a major challenge in long duration spaceflight. According to Menon, conventional IV bags have a shelf life of about 16 months, while a crewed mission to Mars could last several years. Transporting enough IV fluid for medical emergencies is also impractical, as a single seriously ill crew member could require more than 100 liters.

Instead of carrying large quantities of saline, the system uses a filtration process to purify the station’s recycled drinking water to pharmaceutical standards before mixing it with premeasured sodium chloride to create normal saline.

“As a physician, this one hits close to home,” Menon wrote. “If we can make IV fluid 250 miles up, we can make it in a field hospital, a disaster zone, or anywhere the supply chain doesn’t reach.”

The experiment is part of NASA’s efforts to develop technologies that support astronaut health during future deep space missions while also yielding innovations with practical applications on Earth.

Earlier, on his first day aboard the orbiting laboratory, Menon posted an emotional video message expressing gratitude to family, friends, former colleagues at SpaceX, and the organizations that helped shape his career.

“Hello from the International Space Station. It’s day one for me,” he said, thanking his family and wishing his daughter Grace a happy birthday.

Menon also acknowledged his former colleagues at SpaceX, saying they had taught him “how to do the impossible,” a lesson he said he has relied on throughout his career.

Addressing members of the U.S. Space Force, he called space “the biggest domain” and said he was proud to serve alongside them. He also praised NASA’s ambitious plans for lunar and Mars exploration.

“I am happy to be working alongside of you, using the space station as a stepping stone to those huge dreams of ours. Let’s go, team. Let’s do this,” Menon said.

Menon is serving aboard the ISS as part of NASA’s latest long duration mission, where he will contribute to scientific research and technology demonstrations designed to advance human space exploration and improve life on Earth.
