- On June 25 at 08:31 CEST, SpaceX Crew Dragon “Grace” launched from Pad 39A with four astronauts on Axiom Mission 4 (Ax-4).
- Peggy Whitson (USA) commands Ax-4 and is on her fifth spaceflight, with a U.S. orbital record of 675 days.
- Shubhanshu Shukla (India) is Pilot for Ax-4, becoming the first Indian in space since 1984.
- Sławosz Uznański-Wiśniewski (Poland) is the first Polish national on the ISS and the second Pole in space.
- Tibor Kapu (Hungary) is Ax-4’s Mission Specialist, marking Hungary’s first visitor to the ISS.
- Poland’s 47-year space drought ends with Ax-4, following Mirosław Hermaszewski’s 1978 Soyuz 30 mission.
- Uznański-Wiśniewski was born April 12, 1984, is an electronics and radiation-hardened systems engineer at CERN, and was selected as Poland’s Project Astronaut in 2022.
- IGNIS carries 13 experiments on Ax-4’s ~60-experiment manifest, including SpaceRadMon-NG from CERN, SigmaLabs, AstroMentalHealth, micro-algae bioreactors, and tardigrade resilience studies.
- The mission timeline includes launch on June 25, orbital insertion after 9 minutes, autonomous rendezvous on June 26 around 13:00, hatch opening around 15:10, a 14-day research program June 26–July 10, with splashdown targeted around July 11.
- SpaceRadMon-NG will beam down ISS radiation maps within 72 hours, while Hungary disclosed $100 million funding for Ax-4 as part of the commercial-orbit effort.
1. Why today’s flight matters
At 02:31 EDT (08:31 CEST) a brand-new SpaceX Crew Dragon christened Grace roared off pad 39A, carrying four astronauts on Axiom Mission 4 (Ax-4)—and with them the dreams of three nations returning to human space-flight after more than four decades. Among the passengers is Dr Sławosz Uznański-Wiśniewski, who just became the second Pole ever—and the first Polish national on the ISS. wiadomosci.onet.pl 1

3. A Polish comeback 47 years in the making
- Poland’s only previous space-traveller was Mirosław Hermaszewski aboard Soyuz 30 in 1978; Ax-4 ends that drought. 3
- Watching from Warsaw’s Copernicus Science Centre, Prime Minister Donald Tusk enthused: “We’ve got this! Poland has reached for the stars.” 4
- ESA Director-General Josef Aschbacher called Uznański a “bright star” for European space ambitions. 5

5. Science payload: why IGNIS matters
Poland brands its ISS contribution IGNIS—13 experiments embedded in Ax-4’s ~60-experiment manifest. Highlights:
- SpaceRadMon-NG mini-dosimeter from CERN and Polish start-up SigmaLabs to map ISS radiation hot-spots. 6
- AstroMentalHealth video-diary study of astronaut psychology led by Dr Agnieszka Skorupa (University of Silesia). 7
- Micro-algae bioreactors and tardigrade resilience studies coordinated by ESA for advanced life-support. 4

7. The bigger picture: commercial orbit, political drama
- Axiom Space is using these charter flights to pave the way for a private ISS successor; modules begin arriving in 2028. 2
- Launch slipped six times amid an online spat between Elon Musk and U.S. president Donald Trump, who threatened to cancel federal contracts. 9
- All three governments paid for their seats; Hungary disclosed $100 million; Poland and India remain mum. 9

9. What to watch for
- Radiation data drop: SpaceRadMon-NG will beam down its first ISS radiation maps within 72 hours.
- Prime-ministerial calls: Narendra Modi and Donald Tusk are both scheduled to hold live ISS calls next week. 4
- Return leg: Dragon Grace must survive a blazing re-entry and Atlantic splash-down—always the mission’s riskiest phase.
Bottom line
Ax-4 is more than a joy-ride for a quartet of national heroes; it is a dress rehearsal for a post-ISS future where commercial stations, emerging space nations and seasoned explorers share the same orbit. With pierogi, micro-algae and a radiation monitor aboard, Poland’s star scientist embodies that future—and, judging by today’s flawless launch, the future has already begun.
