Two astronauts stranded on the International Space Station (ISS) for over six months are surviving on resourceful but unconventional means, including soup made from recycled urine. NASA astronauts Sunita “Suni” Williams, 59, and Barry “Butch” Wilmore, 61, were originally set for an eight-day mission in June 2024, but technical malfunctions have delayed their return until February 2025.
The Mission That Turned Into an Ordeal
The NASA astronauts were left stranded when the Boeing Starliner spacecraft, which was supposed to bring them back to Earth, suffered from helium leaks and thruster malfunctions. Deemed unsafe for a return trip, the spacecraft forced Wilmore and Williams to extend their stay aboard the ISS indefinitely until a SpaceX Dragon capsule could be prepared to rescue them.
Initially, their meals included fresh fruits, roast chicken, and pizza, but as their mission stretched on, they transitioned to freeze-dried casseroles, powdered milk cereal, and soups reconstituted with water recycled from their own urine and sweat. The ISS employs an advanced 530-gallon water recycling system to ensure minimal waste.

Health Concerns and Resource Management
The astronauts’ reliance on these unconventional food and water sources has sparked concerns about their health. NASA has emphasized that the astronauts receive 3.8 pounds of food per day, carefully monitored to meet nutritional needs. However, recent images of Williams have led to speculation about weight loss.
Williams addressed these concerns in a video, attributing her appearance to microgravity-induced “fluid shifts,” which redistribute bodily fluids and make astronauts’ faces appear puffier while their limbs appear thinner. “We’ve been on the workout gear,” she said, adding that rigorous exercise, including squats and weightlifting, has even increased her muscle mass.
NASA specialists reiterated that food supplies aboard the ISS are sufficient, and emergency reserves are available to sustain extended missions. Meals are prepared on magnetized trays with utensils to prevent floating mishaps, a necessity in the zero-gravity environment.
Waiting for Rescue
A SpaceX Dragon craft is scheduled to bring the astronauts home in February 2025, but until then, Wilmore and Williams will continue adapting to the challenges of extended space travel. Their ability to endure this ordeal highlights the ingenuity and resilience required for human space exploration.
These NASA astronauts’ survival on soups made with recycled urine underscores the extreme measures necessary to sustain life in space. While unconventional, their experience offers invaluable insights into resource management and the psychological endurance required for future missions beyond Earth.
