The Deep Space Food Challenge aims to generate new food production technologies or systems, which would have little waste produced or resources required. Astronauts should be able to focus on their missions and have food production as only a secondary requirement, according to challenge documents, so that they can focus on science — the main purpose of their work in space.

The ideal result will be food that is safe for long-term spaceflight and nutritious for astronauts – as well as tasty, which will encourage people to continue eating during long space voyages. These food systems and technologies may be repurposed in places on Earth with poor food resources, or for people who are living in isolated, confined environments like simulated space habitats.

 "We are excited … to push the boundaries of food technology production that will help keep our future explorers healthy, knowing that some of these technologies could also have great terrestrial applications," Jim Reuter, associate administrator for NASA's space technology mission directorate, said in a NASA statement.

NASA and CSA each have their own application process, so pick the agency situated in the country where you are residing. People living in other countries may participate, but are not eligible for prizes; you can read more about international opportunities here. In all categories, Phase 1 submissions are due on July 30, 2021.
