Video: 00:04:00 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).

Video: 00:09:27 The upcoming Copernicus Radar Observation System for Europe in L-band (ROSE-L) will provide continuous day-and-night all-weather monitoring of Earth’s land, oceans and ice, and offer frequent observations of Earth’s surface at a high spatial resolution. ROSE-L will carry an active phased array synthetic aperture radar instrument. The radar antenna will be the largest deployable planar antenna ever built measuring an impressive 40 sq m. ROSE-L will deliver many benefits including essential information on forests and land cover, leading to improved monitoring of the terrestrial carbon cycle and carbon accounting. The mission will also greatly extend our ability to monitor minute surface displacements and helping detect geohazards. It will automatically map surface soil moisture conditions over land helping improve hydrology and weather forecasts, and support the operational monitoring of sea and land ice across the Arctic. ROSE-L is one of six Copernicus Sentinel Expansion missions that ESA is developing on behalf of the EU. The missions will expand the current capabilities of the Copernicus Space Component – the world’s biggest supplier of Earth observation data. This video features interviews with Malcolm Davidson, ROSE-L Mission Scientist, Nico Gebert, ROSE-L Payload Manager and Gianluigi Di Cosimo, ROSE-L Project Manager.

Video: 00:03:29 After years of development and a rigorous testing programme, ESA’s EarthCARE satellite has left Munich, Germany, and is now on its away to SpaceX’s launch site in Vandenberg, California. Once it arrives, it will be put into storage for a few weeks until it is time to ready the satellite for liftoff – which is scheduled to launch in May on a Falcon 9 rocket. The Earth Cloud Aerosol and Radiation Explorer, or EarthCARE for short, is the most complex Earth Explorer mission to date. The new satellite will look at the role that clouds and aerosols play in heating and cooling Earth’s atmosphere – contributing to our understanding of climate change. With its unique set of four instruments, EarthCARE will examine the role clouds and aerosols play in reflecting solar radiation back into space and also in trapping infrared radiation emitted from Earth’s surface. EarthCARE is a joint venture between ESA and JAXA, the Japan Aerospace Exploration Agency. This video features interviews with Simonetta Cheli, Director of Earth Observation Programmes at ESA, Thorsten Fehr, ESA’s EarthCARE Mission Scientist, Dirk Bernaerts, ESA’s EarthCARE Project Manager and Eiichi Tomita, JAXA’s EarthCARE/CPR Project Manager.

Video: 00:01:44 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. View the full article

Space has led to technological innovations with wide-ranging applications in healthcare. Beyond consumer gadgets, such as wireless headsets and scratch-resistant lenses, space exploration is a catalyst for understanding the human body and advancing scientific results that benefit people worldwide. Here are Europe’s top 5 stories in space for your health. Gravity affects everything we do and everything that happens inside and around us. On Earth’s surface, everything is subject to an average gravitational acceleration of 9.81 m/s2, or what we call 1 g. This acceleration keeps us grounded but it also influences all reactions and phenomena around us, from falling apples to cell growth. Microgravity conditions allow scientists to study phenomena free from the influence of gravity and investigate in depth the fundamental mechanisms at play. The International Space Station provides uninterrupted periods of weightlessness and offers the opportunity for scientists to conduct research, with the help of astronauts on board, that would be impossible to perform on Earth.

Video: 00:07:30 Meet the people working on the testing of Ariane 6. Europe’s next rocket, Ariane 6, has passed all its qualification tests in preparation for its first flight, and now the full-scale test model will be removed from the launch pad to make way for the real rocket that will ascend to space. To make way for launch, teams from ArianeGroup, France’s space agency CNES and ESA have started to remove the Ariane 6 test model by disconnecting the cables and fuel lines that pass through the launch tower. Find out about the progress being made at the end of testing by the people who know Ariane 6 best. Featuring interviews with ESA’s launch system architect Pier Domenico Resta, CNES Inspector General Bernard Chemoul, CNES Ariane 6 project manager Olivier Bugnet, ESA Launch system engineer Frank Saingou, ArianeGroup system test program manager Valérie and ArianeGroup production engineering manager Lydia Amakoud. 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.

Video: 00:09:47 According to the Food and Agriculture Organization (FAO), global agricultural production will need to increase by 60% by 2050 to meet the food demands of the growing global population. A new satellite called Copernicus Hyperspectral Imaging Mission for the Environment, or CHIME, is being developed to support EU policies on the management of natural resources – ultimately helping to address the global issue of food security. CHIME will carry a unique visible to shortwave infrared spectrometer to provide routine hyperspectral observations to support new and enhanced services for sustainable agricultural and biodiversity management, as well as soil property characterisation. CHIME is one of six Copernicus Sentinel Expansion missions that ESA is developing on behalf of the EU. The missions will expand the current capabilities of the Copernicus Space Component – the world’s biggest supplier of Earth observation data. This video features interviews with Marco Celesti, CHIME Mission Scientist and Jens Nieke, CHIME Project Manager. View the full article
