The Space Show presents Dr. Ryan Dowdy on NASA food for the Shuttle & Artemis Missions

The Space Show Presents Dr. Ryan Dowdy re ISS & Artemis Astronaut Food, May 15, 2026, FridayQuick Summary:The Space Show featured Dr. Ryan Dowdy, a former NASA ISS Food System Manager, discussing food in space and his commercial food company ReadyBar. Dowdy explained how NASA’s 20-person team in Houston produces all space food, with 60+ signatures required for each item due to government regulations. He detailed the challenges of providing nutrition for astronauts, including the need for 500-calorie meal replacement bars and the importance of fresh food for psychological well-being. The discussion covered topics like packaging limitations, radiation effects on food, and the potential for growing food in space. Dowdy also shared information about his company ReadyBar, which makes meal-replacement bars designed to replace an entire meal with 30 grams of protein and 15 grams of fiber for $5.99, currently sold online with plans to expand to retailers and Amazon. The conversation explored how commercial space companies are developing their own food systems and the need for continued R&D investment in space food technology.Detailed Summary:Ryan discussed the challenges and innovations in providing food for astronauts, particularly focusing on NASA’s ISS and Artemis missions. He explained how meal replacement bars became popular due to cost and packaging efficiency considerations, noting that 60% of food weight on the ISS was packaging that was discarded. Ryan described his work at NASA from 2016, where he helped update the food menu by adding more fish, fruits, and vegetables to address astronauts’ nutritional needs for omega-3 fatty acids and antioxidants. The discussion concluded with Ryan sharing how he initially became interested in space food science through a professor’s suggestion to directly ask NASA about their challenges rather than proposing solutions without understanding their needs.Ryan also discussed his experience as the ISS Food System Manager at NASA’s Space Food Systems Laboratory, explaining how food scientists create meals designed to last up to two years in space. He described the process of working with astronauts to taste and rank approximately 200 menu items, noting that while shrimp cocktail was a popular choice, the Russian crew preferred more soup in their meals, leading to food exchanges between the two teams. When asked about future food options for space missions, Ryan clarified that while no insects were consumed on the ISS during his tenure, there is potential for growing food in space, though current plant growth experiments like the Veggie system didn’t provide sufficient daily calories. He concluded that while space food systems aren’t ready for long-duration missions like Mars yet, continued research through initiatives like the Deep Space Food Challenge is necessary.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentWe use Zoom phone numbers for program participation.For real time program participation, email Dr. Space at: [email protected] for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.
