It was a difficult campaign to organise, but the scientific results are some of the best ever. Earlier this month, over 60 researchers ran 11 experiments in an Airbus aircraft with no less than three pilots. This was no ordinary flight: the A310 'Air Zero G' flew in repeated arcs 600 m up and down, providing ‘weightlessness’ in freefall conditions for all passengers and their experiments, 20 seconds at a time.

Call for Media: ESA and ClearSpace SA sign contract for world’s first debris removal mission

26. November 2020 - 9:30

Press Release N° 26–2020

ESA is signing an €86 million contract with an industrial team led by the Swiss start-up ClearSpace SA to purchase a unique service: the first removal of an item of space debris from orbit. As a result, in 2025, ClearSpace SA will launch the first active debris removal mission, ClearSpace-1, which will rendezvous, capture and bring down for reentry a Vespa payload adapter. Journalists are invited to follow an online round table for media on Tuesday, 1 December, at 13:30 CET. Mission experts will give an overview of the project status, explain the ambitious mission design and detail the next steps leading to launch.

Over to you, Eumetsat!

24. November 2020 - 16:27

It was a spectacular launch on 21 November, as the Copernicus Sentinel-6 Michael Freilich satellite was lifted into space on a SpaceX Falcon 9 rocket. After taking care of the Earth observation spacecraft during the critical early days and making it at home in its new environment, ESA is ready to hand over control to Eumetsat.

New Copernicus satellite to monitor sea-level rise launched

21. November 2020 - 20:49

The Copernicus Sentinel-6 Michael Freilich satellite has been launched into orbit around Earth on a SpaceX Falcon 9 rocket. Using the latest radar altimetry technology, this new satellite is set to  provide a new overview of ocean topography and advance the long-term record of sea-surface height measurements that began in 1992 – measurements that are essential for climate science, for policy-making and, ultimately, for protecting the lives of millions at risk of sea-level rise.

Watch the replay of Copernicus Sentinel-6 Michael Freilich lifting off from the Vandenberg Air Force Base, California, US, on 21 November 2020. Copernicus Sentinel-6 Michael Freilich is the first of two identical satellites to provide critical measurements of sea-level change. This latest Copernicus satellite will continue the long-term record of reference measurements, extending the record of sea-level height into a fourth decade. Mapping 95% of Earth’s ice-free ocean every 10 days, it will also provide crucial operational data for ocean forecasting.

The Copernicus Sentinel-6 mission is a true example of international cooperation. While Sentinel-6 is one of the European Union’s family of Copernicus missions, its implementation is the result of the unique collaboration between ESA, NASA, Eumetsat and NOAA, with contribution from the French space agency CNES.

Learn how climate change is causing our seas to rise and how satellites have been measuring the height of the sea surface systematically since 1992. With global sea level now rising fast, Copernicus Sentinel-6 Michael Freilich picks up the baton as the latest satellite mission to extend the legacy of sea-surface height measurements. Learn how it makes these critical measurements.

Creating chaos: Craters and collapse on Mars

19. November 2020 - 12:00

Elevation can be deceiving in satellite imagery of Mars, even when differences are extreme – as demonstrated by this image of Pyrrhae Regio from ESA’s Mars Express. A chunk of terrain has collapsed and dropped more than four kilometres below its surroundings, illustrating the incredible contrast and dynamism seen across the martian surface.
