Vickie Kloeris is a food scientist with an out of this world career. She worked at NASA in space food systems for 34 years. She served as the NASA manager of the Shuttle first and then the International Space Station food systems. She and her teams worked through the complex challenges of creating tasty, nutritious, long-lasting, easy-to-prepare meals that support the dietary and psychological needs of astronauts living on the space station. Vickie has worked with 100s of astronauts to plan their favorite meals and holiday specialty meals for space travel.

We talk about the history of feeding our astronauts; working with the US military; evolution of food systems at NASA to feed our astronauts; depending on the Russian space agency in the initial days and also working with other space agencies. Vickie shared the challenges for the future manned mission to Mars; and how food science and technology has been at the core of so many food preparation and packaging technologies we take for granted. We also talk about how we might be able to use these technologies to address hunger and reduce food wastage.
