ESA project astronaut Sławosz Uznański-Wiśniewski operates one of ESA’s space freezers, known as MELFI (Minus Eighty-Degree Laboratory Freezer for ISS), during his stay aboard the International Space Station.
The European space freezers are used to store biological samples such as urine, blood and saliva at temperatures typically around –90°C. Astronauts must wear gloves when handling them due to the extreme cold.
Sławosz was launched to the ISS aboard the Dragon spacecraft as part of Axiom Mission 4 on 25 June 2025. During the 20-day Ignis mission, he carried out 13 experiments proposed by Polish companies and

This stunning time-lapse of the Moon was captured by ESA project astronaut Sławosz Uznański-Wiśniewski from the International Space Station during the Ignis mission.
Sławosz was launched to the ISS aboard the Dragon spacecraft as part of Axiom Mission 4 on 25 June 2025. The 20-day mission, called Ignis, involved 13 experiments from Polish companies and institutions developed in cooperation with ESA, in addition to three ESA-led experiments. These covered a wide range of disciplines including human research, materials science, biology, biotechnology and technology demonstrations.
The Ax-4 mission is the second commercial human spaceflight with an ESA project

GalaxySpace, a commercial space company based in Beijing, has introduced a pioneering rollable solar panel that dramatically reduces satellite bulk while boosting energy efficiency. Presented at a recent conference in Yibin, the new solar wing can be compacted to the size of a water bottle but unfolds in orbit to cover 20 square meters. Xu Ming, CEO of GalaxySpace, explained that the solar

Proteins, the molecular machines of life, are constructed from 20 amino acids in seemingly infinite combinations-up to 10^78 possible sequences for a 60-residue protein. Yet only a tiny subset fold into stable, functional shapes. A new study published in Science reveals that the rules guiding these folds may be far more forgiving than previously assumed. Scientists from the Centre for Geno

The MetOp Second Generation-A1 satellite has reached a significant milestone in its journey to orbit, with fuelling operations now complete at Europe's Spaceport in French Guiana. Engineers successfully loaded 790 kg of hydrazine onto the spacecraft, paving the way for the next phase of pre-launch activities. This satellite, MetOp-SG-A1, is the first in a series of three A-B satellite pair

China has introduced new regulations to tighten quality oversight of its growing commercial space industry. The directive, issued Monday by the China National Space Administration (CNSA), outlines comprehensive management standards intended to guide projects from initial design through final decommissioning. The new rules assign explicit responsibilities to various stakeholders and emphasi
