Mission IGNIS
Pierogi in Space: Sławosz Uznański - Wiśniewski ate the first Polish pierogi on the ISS
8 Jul 2025



Polish tradition in zero-gravity — freeze-dried pierogi with cabbage and mushrooms have won the hearts of viewers of the ISS broadcast.
Though the IGNIS mission focuses on ambitious scientific research and groundbreaking experiments, one of the latest broadcasts from aboard the International Space Station turned unexpectedly... homely. Sławosz Uznański-Wiśniewski, during the “Ax-4 Mission Update” broadcast, presented to the world cabbage and mushroom pierogi specially prepared for him, which he had taken to space.
These were the first ever freeze-dried traditional Polish pierogi eaten in orbit. This comfort food from Poland was prepared by the company LYOFOOD in collaboration with chef Mateusz Gessler, on special order from Sławosz before the mission. The astronaut himself admitted that he wanted to take a piece of Polish culture and tradition into space — and symbolically share it with the entire crew.
A moving moment during the transmission
The moment of presenting pierogi became the warmest highlight of the conference, which was entirely dedicated to the scientific objectives of the mission. Peggy Whitson, the commander of the Ax‑4 mission, joked that Sławosz takes a "selfie" with every experiment and piece of equipment at every free moment, and pierogi quickly became another "star" of his photos. Sławosz also explained that the taste of pierogi in space was a "pleasant return home" and an important element of adapting to the demanding life in a weightless state.
Science and Tradition Go Hand in Hand
During the broadcast, the astronaut also spoke about Polish experiments he is conducting as part of the IGNIS mission: testing brain-computer interfaces, researching nanomaterials (MXene), volcanic algae, and experiments on astronauts' mental health. He emphasized that working in microgravity requires adaptation, but thanks to such small, symbolic gestures, it's easier to feel "at home."
Not Just Pierogi
Besides the moment with pierogi, the crew conducted further studies that day:
Sławosz conducted EEG Neurofeedback and AstroMentalHealth experiment sessions, documenting them for teams on Earth.
Peggy Whitson continued experiments on cancers.
Shubhanshu Shukla studied muscles and cultivated microalgae, while Tibor Kapu conducted DNA tests on fruit flies.
Polar Day over the ISS
It's noteworthy that on that day aboard the ISS began a "cosmic polar day," a period of uninterrupted sunlight lasting several days — exceptional conditions for both the station's systems and the astronauts.
Summary
The moment with pierogi became a beautiful symbol of the IGNIS mission — combining science, courage, and a sentiment for Polish traditions. They were proof that even in the most demanding environment, it's possible to maintain a connection with one's own country and culture.
"Space tastes like Poland — Sławosz concluded during the broadcast. — Pierogi will always find their place, even in orbit."
