The invention, which cooks cylinder-shaped pizzas and other foods, recently moved on to the final phase of NASA's Deep Space Food Challenge.
One Boulder scientist is working to change the game when it comes to food in space.
A true engineer with the obsession of an inventor and the tenaciousness of a tinkerer, Sears had already converted his garage into a full workshop with a milling machine, lathe, bandsaw and microscopes. Located on a quiet residential cul-de-sac in Boulder, it's stuffed to the brim with hardware, electrical components and parts that he used to begin prototyping his idea.
He named his invention the SATED oven, which stands for"safe appliance, tidy, efficient and delicious." On Christmas Day 2020, he invited his family to the garage to taste some cylindrical pancakes and “inside-out” pineapple cake. It wasn’t entirely edible — Sears had yet to dial in the recipes — but it was a milestone nonetheless: He had proven that his SATED oven could cook.
“So right now, the food system is based on packaged food on the ISS, but they do have to resupply — they take fresh foods sometimes as well as treats to replenish the menu and give it some variety,” explains DSFC manager Angela Herblet. “But when you think about deep space, we’re not going to be able to do that. So it has to be many things. It can be pre-packaged food, it can be fresh food, 3D-printed food, mushroom protein. ...
In March, two NASA judges visited Sears's garage for an on-site demonstration, which he says was a rousing success. They stayed for four and a half hours and made eight different meals. Sears originally made them a pepperoni and cheese pizza, “and then one of the judges, she took over and made everything else from then on," he says."And so they had the thrill of discovery themselves...and that was exactly what I was trying to create.
Once ready, Abuhamad used two 3D-printed holders to lift the cylindrical pizza and set it on a cutting board. It was an odd-looking pizza, for sure — five inches in diameter and almost three inches tall — but once Abuhamad cut down the side, it unfurled into a long, skinny flatbread pizza.My dining partner described the flavor as “middle-school cafeteria pizza, but in the best way.
The Phase III requirements are set to be released “in the next few weeks,” according to Herblet, but NASA was able to provide some details about the judging. Each participant will be taken to a designated facility where they will train a qualified crew on how to work their technology. Then the crew will test it under analog conditions repeatedly and provide feedback to the judges.
There are hundreds of little details to consider when engineering for space. You can’t have red buttons or lights, for example, because red on the station signifies an emergency or disaster. “We flew a power module for a piece of hardware a few years back, and it had three different lights on it,” remembers Countryman.
