"Advanced recycling" promises to convert dirty, mixed waste plastic into brand new plastic time and time again. It is a major step towards creating a circular economy and fighting climate change

Did you know Galileo was born in the Netherlands in the 1990s? Europe’s own global navigation satellite system was developed in ESA’s technological heart, ESTEC, in Noordwijk, almost three decades ago. Since then, it has grown to become one of the most complex and critical infrastructures ever built in Europe, as well as the largest European satellite constellation and ground segment.

Watch a replay of the ESA astronaut class of 2022 graduation ceremony.

ESA astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg received astronaut certification at ESA’s European Astronaut Centre on 22 April 2024. This officially marks their transition into fully-fledged astronauts, ready and eligible for spaceflight.

The group was selected in November 2022 and began their year-long basic astronaut training in April 2023.

Basic astronaut training provides the candidates with 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 astronauts will move on to the next phases of pre-assignment and mission-specific training, paving the way for future missions to the International Space Station and beyond.
