Meet Arnaud Prost—aerospace engineer, professional diver, and member of ESA’s Astronaut Reserve. From flying aircraft to getting a taste of spacewalk simulation, his passion for exploration knows no bounds.

In this miniseries, we take you on a journey through the ESA Astronaut Reserve, diving into the first part of their Astronaut Reserve Training (ART) at the European Astronaut Centre (EAC) near Cologne, Germany. Our “ARTists” are immersing themselves in everything from ESA and the International Space Station programme to the European space industry and institutions. They’re gaining hands-on experience in technical skills like spacecraft systems and robotics, alongside

When the plasma inside a fusion system starts to misbehave, it needs to be quickly cooled to prevent damage to the device. Researchers at Commonwealth Fusion Systems believe the best bet is a massive gas injection: essentially, a well-timed, rapid blast of cooling gas inside their fusion system, which is known as SPARC. But how many gas valves does it take to quickly tame a plasma that is hotter

The first image from a new Italian Earth observation satellite mission was published today: a high-resolution image of a strip of the Italian peninsular showing the city of Rome at a resolution of 2.66 metres. This is three times higher than the resolution currently available for systematic acquisition over Italy.

Don't tell Neil Armstrong, but giant leaps for mankind may leave astronauts feeling a little queasy. In a new experiment, aerospace engineers at the University of Colorado Boulder will work with astronauts to study how people experience motion sickness when they travel to space-with an eye toward reducing these sometimes debilitating symptoms. The research is part of the first-of-its
