Axiom Space’s fourth private astronaut mission will carry astronauts from four nations to conduct cutting-edge research aboard the International Space Station
Mission Opened
Axiom Space has officially opened media accreditation for the upcoming Axiom Mission 4 (Ax-4), scheduled to launch no earlier than spring 2025 from NASA’s Kennedy Space Center in Florida. The mission will utilize a SpaceX Falcon 9 rocket to propel a Crew Dragon spacecraft to the International Space Station (ISS).
Overview and Launch Details
The Ax-4 mission represents the fourth private astronaut mission by Axiom Space to the ISS, with the crew expected to spend approximately 14 days conducting scientific research, technology demonstrations, educational outreach, and commercial activities in the microgravity environment.
Multinational Crew Composition
Ax-4 features a truly international crew lineup:
- Commande Peggy Whitson– A veteran astronaut and former NASA astronaut who now serves as Axiom Space’s Director of Human Spaceflight and Chief Astronaut
- Pilot Shubhanshu Shukla – An Indian test pilot and Group Captain in the Indian Air Force, he will be one of the first from the Indian Human Spaceflight Programme to fly on a private mission
- Mission Specialist Sławosz Uznański-Wiśniewski – An ESA project astronaut from Poland who will lead the “Ignis” mission segment, marking Poland’s first manned mission since Mirosław Hermaszewski’s flight on Soyuz 30
- Mission Specialist Tibor Kapu – A Hungarian mechanical engineer selected under Hungary’s HUNOR programme, potentially becoming the third Hungarian in space after Bertalan Farkas and Charles Simonyi
The “Ignis” Mission: Poland’s Scientific Initiative
A key component of Ax-4 is the “Ignis” mission, sponsored by the Polish government and supported by ESA. This ambitious scientific and technological program includes 13 Polish experiments focusing on:
- Effects of microgravity on the human immune system
- Nanomaterials behavior in space
- Cosmic radiation sensors development
- Kp lab data processing designed to leverage AI for processing space data
This mission represents a historic milestone for Poland’s space program and demonstrates the country’s growing capabilities in space research and technology.
Additional Scientific Experiments
Beyond the Polish scientific program, the Ax-4 mission will support various research initiatives, including the “Suite Ride” study. This pioneering experiment aims to explore possibilities for enabling space travel for insulin-dependent diabetics, potentially opening space access to a broader population.
