At The ISS, Astronaut Jonny Kim Creates Improvised Burger and Highlights Challenges of Eating with Limited Ingredients and No Gravity
In the absence of fast food or fresh ingredients, a NASA astronaut decided to improvise an unusual snack aboard the International Space Station (ISS).
The creation, made with processed foods available on the spacecraft, went viral on social media and drew attention to the challenges of eating on space missions.
Improvised Creation in Orbit
Jonny Kim, a NASA astronaut currently on a mission at the ISS, shared on X (formerly Twitter) his version of a burger adapted to the conditions of space. Named the “Ranger Burger,” the dish consists of beef steak, whole wheat bread, cheese spread as both topping and glue, potatoes au gratin layered in the middle, and a special package of gochujang red chili paste sent from the SpX-32 Cargo Dragon mission.

China has created a mass-produced hypersonic missile that costs the same as a Tesla, and this is changing everything in modern warfare because the United States cannot defend itself without spending millions.

100% Brazilian technology transforms agricultural waste into a meat-scented ingredient using fungi from the Amazon rainforest. The process does not use excessive water or chemicals, and it also increases the nutritional value of the final product.

Psychology reveals that adults who avoid conflicts at all costs are not balanced individuals, but rather children who learned in the worst way that expressing emotions brought punishment and now live paralyzed by the fear of expressing themselves.

Goodbye pet hair on clothes: a washer with an internal filter promises to remove up to 5 times more hair than regular machines and uses an XL trap dryer system to capture what remains.
“I miss cooking for my family, but this surprised me in its own way,” Kim wrote. He has been aboard the station since early April and will remain on mission for eight months, according to the Daily Mail.
Limited Nutrition and Creativity
In microgravity, the nutrition of astronauts demands creative solutions. Aside from different flavors, the limitation of fresh ingredients makes the menu quite restricted.
While it’s easy to judge the appearance of Kim’s burger, it’s important to remember that creativity is essential to ensure calories and nutrients in the space environment.
Other astronauts have faced similar situations. During a five-month stay at the ISS, two colleagues ate pizza, roasted chicken, and even shrimp cocktail.
Despite the occasional variety, the basis of their diet consists of processed foods, vacuum-sealed or freeze-dried.
Challenges with Fruits, Vegetables, and Even Coffee
At the start of missions, fresh fruits are sent with the supplies. But after about three months, only packaged or dehydrated versions remain.
The steak used by Kim, for example, was prepared on Earth and sent ready to be reheated in space.
Even drinking coffee requires adaptation. Astronauts use a Zero-G cup, which guides the liquid to their mouths with the help of capillary action. “We take gravity for granted,” commented veteran astronaut Don Pettit, about the challenge of even drinking coffee.
