A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyses them for hints of life. ESA has started to turn this scene into a reality, devising a mission to investigate an ocean world around either Jupiter or Saturn. But which moon should we choose? What should the mission do exactly? A team of expert scientists has delivered their findings. View the full article

Imagine being able to ask a chatbot, “Can you make me an extremely accurate classification map of crop cultivation in Kenya?” or “Are buildings subsiding in my street?” And imagine that the information that comes back is scientifically sound and based on verified Earth observation data. ESA, in conjunction with technology partners, is working to make such a tool a reality by developing AI applications that will revolutionise information retrieval in Earth observation.

Video: 00:17:57 Air pollution is the largest environmental health risk in Europe and significantly impacts the health of the European population, particularly in urban areas. Following on from the Sentinel-5P satellite – the first Copernicus mission dedicated to monitoring our atmosphere – the Sentinel-4 and Sentinel-5 missions will take current air quality measuring capabilities to the next level. Together, the Sentinel-4 and -5 missions will provide information on atmospheric variables in support of European policies. This will include the monitoring of air quality, stratospheric ozone and solar radiation, and climate monitoring. This video features interviews w…

A few layers of water ice – the width of a strand of DNA – are starting to impact Euclid’s vision; a common issue for spacecraft in the freezing cold of space, but a potential problem for this highly sensitive mission that requires remarkable precision to investigate the nature of the dark Universe. After months of research, Euclid teams across Europe are now testing a newly designed procedure to de-ice the mission's optics. If successful, the operations will validate the mission teams’ plan to keep Euclid’s optical system as ice-free as possible for the rest of its life in orbit. View the full article

Image: Astronomers have created the largest yet cosmic 3D map of quasars: bright and active centres of galaxies powered by supermassive black holes. This map shows the location of about 1.3 million quasars in space and time, with the furthest shining bright when the Universe was only 1.5 billion years old. The new map has been made with data from ESA’s Gaia space telescope. While Gaia’s main objective is to map the stars in our own galaxy, in the process of scanning the sky it also spots objects outside the Milky Way, such as quasars and other galaxies. The graphic representation of the map (bottom right on the infographic) shows us the location of quasars from our van…

Video: 00:14:13 Climate change exacerbates droughts by making them more frequent, longer, and more severe. This can have a wide range of impacts on the environment, agriculture, ecosystems and communities including water scarcity, crop failure and food shortages. The upcoming Copernicus Land Surface Temperature Monitoring, LSTM, mission will improve sustainable agricultural productivity in a world of increasing water scarcity and variability. The mission will carry a high spatial-temporal resolution thermal infrared sensor to provide observations of land-surface temperature. These data are key to understand and respond to climate variability, manage water resource…

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.

Video: 00:03:01 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.
