Ax-4 joins the International Space Station
On 26 June 2025 ESA project astronaut Sławosz Uznański-Wiśniewski from Poland and his crewmates arrived to the International Space Station on the Axiom-4 mission (Ax-4).
The Polish project astronaut is the second of a new generation of European astronauts to fly on a commercial human spaceflight opportunity with Axiom Space.
Sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT), and the Polish Space Agency (POLSA), the mission will include an ambitious technological and scientific programme with several experiments led by ESA and proposed by the Polish space industry.

Satellite records expose fire driving Gran Chaco transformation
At ESA’s Living Planet Symposium, scientists have unveiled how the combination of different long-term, high-resolution satellite datasets from ESA’s Climate Change Initiative is shedding new light on the South American Gran Chaco – one of the world’s most endangered dry forest ecosystems. These data reveal, in remarkable clarity, that fire is the primary driver of widespread, accelerating deforestation across the region.
