NASA Develops Space IV Technology: IVGEN Mini Converts Drinking Water to Intravenous Fluid On Demand
Summary: In April 2026, NASA successfully demonstrated the IVGEN Mini system aboard the International Space Station, which can produce medical-grade intravenous (IV) fluid on demand from station drinking water. The system produces 1.2 liters of IV fluid per hour, solving a critical medical challenge for deep space missions where prepackaged IV fluid has a shelf life of only 16 months, while missions to Mars can last up to three years.

NASA has released detailed information about the IVGEN Mini (IntraVenous Fluid GENeration Miniaturized) system. The system was launched to the International Space Station on April 11, 2026, aboard NASA's 24th Commercial Resupply Services (CRS-24) mission and underwent operational demonstrations in April — with astronauts successfully producing 10 liters of IV fluid over two days.
How It Works
The IVGEN Mini operates by adding space station drinking water to a large supply bag, which is connected to the IVGEN Mini main unit. The system filters the water to remove all particulates and mineral ions, and the processed water flows into an output bag containing premeasured sodium chloride, ultimately creating sterile, medical-grade IV fluid that meets United States Pharmacopeia standards.
The system can produce 1.2 liters of IV fluid per hour, meeting medical needs for deep space missions. According to Courtney Schkurko, engineering project manager at NASA Glenn Research Center: "The fluid produced in space will be returned to Earth and analyzed to make sure the fluid that was generated in flight meets requirements and is safe to use."
Solving the Deep Space Medical Challenge
On every crewed mission, NASA packs pouches of a potentially life-saving liquid in its cargo, known as IV (or intravenous) fluid. A simple mix of sodium chloride and purified water, it can treat up to 30% of medical conditions in flight, including dehydration, burns, and more.
However, current IV fluid shelf life is limited to 16 months. For deep space missions that could last up to three years, this means packing large quantities of potentially expired prepackaged IV fluid. IVGEN Mini solves this by producing fluid on demand.
Schkurko added: "On a mission to Mars, if you needed to fly 100 liters of IV fluid, those 100 one-liter bags will take up a large amount of space, while IVGEN Mini takes up much less. It's that trade between packing IV fluid bags that are likely to expire during the mission or taking a small device and making it as you go. The latter means it will always be within expiration period, it will be available to the crew, and it's one less risk we have to worry about."
Technical Evolution
IVGEN Mini is the second iteration of this technology. The original IVGEN was demonstrated aboard the space station in 2010. Since the original required additional sensing equipment to prove the system worked, it was much larger. Building on that success, the team developed the miniaturized version.
"With IVGEN Mini, we've reduced the system's size and weight," said Schkurko. "The previous system used gaseous nitrogen to pump fluid through the system. Now, we have pumps that are miniaturized, which allow us to optimize our designs and refine the filtering process."
Future Applications
IVGEN Mini is managed by NASA's Mars Campaign Office as one of the many technologies developed to enable human exploration on the Moon and Mars. The team is currently planning for shelf-life testing of IV fluid produced by the system as the next phase of this technology.
