One year of basic training will soon bear fruit for ESA’s astronaut candidates Sophie Adenot, Pablo Álvarez Fernández, Rosemary Coogan, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg.

On 22 April 2024, these astronaut candidates will receive their certification at ESA's European Astronaut Centre in Cologne, Germany, officially becoming fully fledged astronauts eligible for spaceflight.

As they reach the end of one year of rigorous basic astronaut training, ESA astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg will receive astronaut certification at ESA’s European Astronaut Centre on 22 April 2024.

The group was selected in November 2022 and began their training in April 2023.

Basic astronaut training provides the candidates with an overall familiarisation and training in various areas, such as spacecraft systems, spacewalking, flight engineering, robotics and life support systems, as well as survival and medical training.

Following certification, the new

One year since the launch of ESA’s Jupiter Icy Moons Explorer (Juice), we catch up with core team members Claire Vallat, Giuseppe Sarri, Olivier Witasse and Ignacio Tanco.

From memories of launch day to hopes for the future, they talk honestly about the ups and downs of flying a space mission, and reveal how they’re ensuring that Juice will be a huge success.

On the last day of his Huginn mission, ESA astronaut Andreas Mogensen takes us on a tour of the place he called home for 6 months: the International Space Station. From the beautiful views of Cupola to the kitchen in Node 1 filled with food and friends and all the way to the science of Columbus, the Space Station is the work and living place for astronauts as they help push science forward.

A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgart Institute of Space Systems (IRS). Arc-heated gas in the test chamber reaches speeds of several kilometers per second, reproducing reentry conditions, while the reaction wheel itself is being rotated, reproducing the tumbling that takes place as a satellite plunges through the atmosphere.

The reaction itself comes from Collins Aerospace in Germany, which has supported Design for Demise (D4D) activities for many years and introduced several modifications to their TELDIX reaction wheel, making it more likely to come apart during reentry in support of demisability.

This clip was presented during this year's Space Mechanisms Workshop at ESA's ESTEC technical center in the Netherlands and focused on current and future requirements and guidelines to reduce the risk from , including ESA's Zero Debris Charter. The event was attended by more than 130 space mechanisms specialists from European industry and academia.

Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the moon or Mars, it is a significant hazard that must be mitigated.
