The Copernicus Sentinel-3 mission captured Cyclone Dikeledi south of Madagascar on 16 January, just a few days after it made landfall on Africa’s southeastern coast causing widespread destruction in several countries and islands.

The European Space Agency (ESA) and the Estonian Space Office have set out to develop Europe’s newest space cyber range that aims to make space technology more secure and accessible for companies across Europe. Last year, Estonian industry was invited to submit proposals for concepts, and today the contract has been signed with a consortium led by Spaceit to begin development.

A study using data from ESA’s Swarm mission suggests that faint magnetic signatures created by Earth’s tides can help us determine magma distribution under the seabed and could even give us insights into long-term trends in global ocean temperatures and salinity.

A capacity increase by almost 80%! In late July 2024, the Malargüe deep-space communication station completed an important upgrade of its antenna feed that will allow missions to send much more data back to Earth.

This Copernicus Sentinel-2 image captures the borders between North and South Dakota and Minnesota blanketed with snow and ice.

The largest photomosaic of the Andromeda galaxy, assembled from NASA/ESA Hubble Space Telescope observations, unveils hundreds of millions of stars. It took more than 10 years to collect data for this colorful portrait of our neighbouring galaxy and was created from more than 600 snapshots. This stunning, colourful mosaic captures the glow of 200 million stars, and is spread across roughly 2.5 billion pixels.

With ESA’s EarthCARE satellite and four measuring instruments all working extremely well and fully commissioned, the mission’s ‘first level’ data stream is now freely available.

By combining data from all four instruments, scientists ultimately aim to address a critical Earth science question: how do clouds and aerosols affect the heating and cooling of our atmosphere?
