The shoebox-sized Milani CubeSat, which will perform close-up mineral prospecting of the Dimorphos asteroid, is ready for delivery to ESA’s Hera asteroid mission for planetary defence. The spacecraft will carry Milani and a second CubeSat, the Juventas radar imaging spacecraft for probing into the target asteroid, which together will be ESA’s first CubeSats to operate in deep space.

ESA’s Arctic Weather Satellite has passed its environmental test campaign with flying colours – meaning that the satellite has been declared fit for liftoff and its life in the harsh environment of space.

This new satellite, which is slated for launch in June, has been designed to show how it can improve weather forecasts in the Arctic – a region that currently lacks data for accurate short-term forecasts.

The European mission control centre near Munich, Germany, is set to undergo a transformation into a Moon mission control centre, tasked with supporting operations for missions to a lunar space station, the lunar surface and beyond.

After more than 6 months on the International Space Station, ESA astronaut Andreas Mogensen returned to Earth, marking the end of his Huginn mission. It was his second mission to the Space Station and his first long-duration, where he was the pilot of Crew-7, which consisted of Jasmin Moghbeli (NASA), Satoshi Furukawa (JAXA), and Konstantin Borisov (Roscosmos).

In just a few months, ESA’s EarthCARE satellite will be lofted into orbit to fill in a piece of the complex climate puzzle – that piece being how clouds and aerosols, small particles such as dust suspended in the air, affect Earth’s energy balance.

With the climate crisis upon us, this information is needed more urgently than ever – so much so, that the science of clouds and aerosols has been prioritised by the European Commission and ESA as part of their new Earth System Science Initiative.

ESA, on behalf of the European Commission, has signed a €12 million contract with Leonardo S.p.A (Italy) and Istituto Nazionale di Ricerca Metrologica to design and develop a new ultra-precise atomic clock technology for Galileo.

After more than six months on the International Space Station,  ESA astronaut Andreas Mogensen and the rest of Crew-7 will undock and make their way down to Earth on 11 March 2024 at 13:15 GMT/14:15 CET, splashing down off the coast the Florida on 12 March, at 09:35 GMT / 10:35 CET. Watch the undocking and splashdown on ESA WebTV.

Rosemary Coogan, one of ESA’s five astronaut candidates currently undergoing basic astronaut training at the European Astronaut Centre in Cologne, Germany, shares her journey from studying the stars to training for space travel. Join us as we discuss her experiences in astronaut training, her favorite lessons, and her excitement for the future of space exploration.

This is Episode 4 of our ESA Explores podcast series introducing the ESA astronaut class of 2022, recorded in November 2023.

Andreas Mogensen launched on his Huginn mission in August 2023 to the International Space Station, becoming the first non-US astronaut to pilot SpaceX’s Crew Dragon spacecraft. Andreas became commander of the International Space Station in September 2023, becoming the longest serving European commander in January 2024. His mission was spent on more than 30 European experiments and plenty of international ones as well, ranging from water purification to studies of human physiology and thunderclouds. After 6 months on the International Space Station, Andreas will come down to Earth together with his Crew-7 crewmates Jasmin Moghbeli (NASA), Satoshi Furukawa (JAXA), and Konstantin Borisov (Roscosmos).

The two central stages for Ariane 6’s first flight are being assembled in the launcher assembly building (BAL) at Europe’s Spaceport. The core stage and the upper stage for Europe’s new rocket Ariane 6 are set to fly in the Summer of 2024. Once assembled, the stages will be transferred to the launch pad.

On the launch pad, the two stages will be raised into their vertical launch position inside the mobile assembly building. Here the two boosters for Ariane 6’s first flight will be added and then the payloads will be placed on top and be covered by the fairing – Ariane 6’s nose cone that splits vertically in two.

The stages arrived at Europe’s Spaceport on novel hybrid sail ship Canopée on 21 February after a two-week transatlantic crossing from mainland Europe.

Ariane 6 is an all-new design, created to succeed Ariane 5 as Europe's heavy-lift launch system. With Ariane 6's upper stage restart capability, Europe's launch capability will be tailored to the needs of multiple payload missions, for example to orbit satellite constellations. This autonomous capability to reach Earth orbit and deep space supports Europe's navigation, Earth observation, scientific and security programmes. Ongoing development of Europe's space transportation capabilities is made possible by the sustained dedication of thousands of talented people working in ESA's 22 Member States.

Ultrasound devices are commonplace in modern orbital medical kits, helping to facilitate rapid diagnoses of astronaut ailments or bodily changes. However it takes real-time guidance from experts on the ground to acquire medically useful ultrasound images. Once astronauts travel to the Moon or further into the Solar System such guidance will no longer be practical due to the time delay involved. A new ESA-led project aims to leverage AI and Machine Learning so that astronauts can perform close to expert quality ultrasound exams by themselves.
