The path that ExoMars 2022 will follow to reach the Red Planet is set. The trajectory that will take the spacecraft from Earth to Mars in 264 days foresees a touchdown on the martian surface on 10 June 2023, at around 17:30 CEST (15:30 UTC).
The space agency logos for the next spacecraft to head to the Moon have been added to Orion as part of the Artemis programme.
The latest ESA Impact is out now!
A European satellite built to carry out precise measurements of sea level changes has arrived in California in preparation for launch. The Sentinel-6 Michael Freilich satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ radar to map sea surface topography.
The mission will be used to monitor the height of the sea surface to understand long-term change. It will also measure wave height and wind speed. The satellite will provide fundamental data for climate science, policy-making and protecting the 600 million people who live in vulnerable coastal areas.
Data are provided to Copernicus services in near-real time to improve marine and weather forecasts used by maritime and coastal communities.
The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French Space Agency CNES.
It is named Michael Freilich after NASA’s former Director of Earth Science and is scheduled for launch on 10 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base.

Satellite imagery has revealed that two of the fastest-changing glaciers in Antarctica are fracturing and weakening faster than ever – the first step towards the glaciers disintegrating and causing sea levels to rise dramatically.
ESA’s Mars Express spacecraft has discovered several ponds of liquid water buried under the ice in the south polar region of Mars. The spacecraft’s radar instrument, MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding), revealed one underground reservoir in 2018, buried about 1.5 km below the ice. Now, taking into account more data and analysing it in a different way, three new ponds have been discovered. The largest underground lake measures about 20 x 30 km, and is surrounded by several smaller ponds. The water is thought to be very salty in order for it to remain liquid at cold temperatures.
Mars was once warmer and wetter with water flowing across the surface, much like early Earth. While it is not possible for water to remain stable on the surface today the new result opens the possibility that an entire system of ancient lakes might exist underground, perhaps millions or even billions of years old. They would be ideal locations to search for evidence of life on Mars, albeit very difficult to reach.
Subglacial lakes are also known on Earth, like Lake Vostok in Antarctica. They may harbour unique ecosystems, providing useful analogies for astrobiologists exploring how life can survive in extreme environments. The techniques used to analyse the radar data on Mars are similar to those used in investigations of subglacial lakes in Antarctica, Canada and Greenland.
The latest batch of tiny satellites to monitor trade on Earth from space have launched.
ESA’s 2020 Φ-week event kicked off this morning with a series of stimulating speeches on Digital Twin Earth, updates on Φ-sat-1, which was successfully launched into orbit earlier this month, and an exciting new initiative involving quantum computing.
ESA’s new exoplanet mission, Cheops, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates Cheops’ unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.
At 09:30 today, ESA’s third edition of the Φ-week event will commence. Φ-week 2020 will be fully digital and will highlight innovation in Earth observation and showcase the latest achievements in Earth observation science, technology and applications.
The launch of the Copernicus Sentinel-6 Michael Freilich satellite – designed to measure the height of the ocean – is getting tantalisingly close. The satellite has now safely touched down at the Vandenberg Air Force Base in central California, where mission teams are busily preparing the satellite for its upcoming journey.
This year marks two decades since the first ESA doctor set foot in Antarctica, running research at one of the most extreme places on Earth in preparation to explore far beyond it.

After leaving the Airbus premises in Madrid on 24 September, the Spanish high-resolution land imaging mission, known as SEOSAT-Ingenio, has arrived safely at Europe’s Spaceport in French Guiana, where it will be prepared for launch later this year.
Telecommunications are becoming increasingly crucial to our society, economy and security. ESA is supporting the European satellite communication industry’s efforts to identify how to meet future worldwide demands for more secure and resilient digital systems.
