To give astronauts better food, engineers test a fridge prototype in microgravity Note to journalists: A video of the researchers testing their fridge design in microgravity is available on YouTube. Additional footage and photos of the experiments aboard the ZERO-G flights are available via Google Drive. Journalists visiting campus should follow visitor health guidelines. WEST LAFAYETTE, Ind. — Astronauts have been going to space since 1961, but they still don’t have a refrigerator to use for keeping food cold on long missions to the moon or Mars.

One of the main challenges of space travel has been food storage. While mankind has been sending people to space as early as 1961, there has never been any refrigerator to keep food cold and fresh during long missions.

Prototype refrigerator for use in microgravity undergoes testing Shane McGlaun - May 28, 2021, 6:29am CDT One of the biggest challenges in long-term space exploration is a source of food for astronauts. While humans have been traveling in space since the 1960s, the way food is stored hasn’t changed much. In particular, food is still typically freeze-dried, and there is no refrigerator to help things last. A team of engineers from Purdue University, Air Squared Inc., and Whirlpool Corporation is at work on a prototype refrigerator that can operate in microgravity. The rese...

Listen to this article WEST LAFAYETTE, Ind. — For astronauts to go on long missions to the moon or Mars, they'll need a refrigerator. But today’s fridges aren’t designed to work in zero gravity – or upside down if oriented that way when a spacecraft lands on another planet. A team of engineers from Purdue University, Air Squared Inc., and Whirlpool Corporation is working on building a fridge for zero gravity that operates in different orientations and just as well as the one in your kitchen, giving astronauts access to longer-lasting and more nutritious food. In May, the ...
