The lower stage of ESA’s next-generation Ariane 6 launch vehicle has been installed on the assembly line at Europe’s Spaceport behind the upper stage. It is now time to join the two horizontally to create the central core of Ariane 6 in readiness for the first combined tests on the launch pad.

The Copernicus Sentinel-2 mission takes us over northwest Lesotho – a small, land-locked country surrounded entirely by South Africa.

One of the many serious consequences of the climate crisis is that precious permafrost is thawing, and this is unleashing even more carbon to the atmosphere and further exacerbating climate change. However, it’s complicated. For example, sometimes permafrost can thaw rapidly and scientists are unsure why and what these abrupt thaws mean in terms of feedback loops. This makes it difficult to predict the future impact on the climate. Thanks to an ESA–NASA initiative, new research digs deep into understanding the complexities of permafrost thaw and how carbon is released over time.

Volcanoes, impact craters, tectonic faults, river channels and a lava sea: a vast amount of information is captured in a relatively small area in this geologically rich new image from ESA’s Mars Express.

For the second time in its mission so far, the ESA/NASA Solar Orbiter spacecraft has flown through the tail of a comet. Predicted in advance by astronomers at University College London, UK, the spacecraft collected a wealth of science data that now awaits full analysis.

Today, at 20:00 CET, the James Webb Space Telescope fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final post launch course correction to Webb’s trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1.5 million kilometres away from Earth.

When Joe Biden was inaugurated as President one year ago, he fulfilled his promise to rejoin the Paris Agreement and set a course for the US to tackle the climate crisis by supporting global efforts to limit global warming. ESA recently joined the President’s Council of Advisors on Science and Technology by public video link to share European plans and expertise on measuring carbon dioxide and methane from space.

Watch the replay of ‘Live from Space: The Next Frontier for Knowledge and Action’. ESA astronaut Matthias Maurer, live from the from the International Space Station discussed with a panel of prominent experts and industry leaders, including ESA’s Director General Josef Aschbacher, about how space research can improve life on our planet.

Part of Mecklenburg–West Pomerania, also known as Mecklenburg-Vorpommern, a state in northeast Germany is featured in this image captured by the Copernicus Sentinel-2 mission. A portion of the northwest coast of Poland can be seen in the right of the image.
