ESA’s Euclid mission will create a 3D-map of the Universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast amount of data, it will cover more than a third of the sky and its third dimension will represent time spanning 10 billion years of cosmic history.

According to the World Meteorological Organization, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region.
Save the date: this year’s annual ESA Open Day in the Netherlands will take place on Sunday 8 October, at the Agency’s ESTEC technical centre in Noordwijk. Registration to attend will be opened later this summer; keep an eye on this webpage and social media for further details.

In July 2023 local time, the last Ariane 5 blasted off from Europe’s Spaceport in French Guiana. Relive the moment from up close in this 360° video showing the liftoff and Ariane 5 soaring to orbit.

The 117th and final launch of Europe’s Ariane 5 rocket capped a series which began in 1996. Commercial, institutional and scientific payloads included such iconic missions as Rosetta, the James Webb Space Telescope and Juice. Seen here is the launch campaign for VA261 on 5 July 2023, to close the Ariane 5 book; onboard were German aerospace agency DLR’s Heinrich Hertz experimental communications satellite and French communications satellite Syracuse 4b.
In recent weeks, devastating wildfires have spread in Greece, Italy, Spain, Portugal, Algeria, Tunisia and Canada, causing human casualties as well as massive environmental and economic damage.

Aeolus’s mission is over, but weather forecasting is improved forever, and a new precedent has been set for safe satellite reentries. The trailblazing Earth Explorer returned through our atmosphere on 28 July, following the path it was guided on by ESA’s mission control over Earth’s most uninhabited regions, finally disintegrating over the Antarctic.
A solar eruption detected simultaneously at Earth, the Moon and Mars emphasises the need to prepare human exploration missions for the dangers of space radiation.

The summer fire season is well under way in Europe – countries all around the Mediterranean are experiencing record temperatures coupled with huge wildfires that have led to mass evacuations. In this enthralling new ESA documentary, explore how people on the frontline are using space to better monitor and fight the flames.
Euclid’s two instruments have captured their first test images. The mesmerising results indicate that the space telescope will achieve the scientific goals that it has been designed for – and possibly much more.
An advanced broadband satellite providing high-speed internet services that demonstrate next-generation 5G connectivity has passed its initial in-orbit tests.

This image shows the irregular galaxy NGC 6822, which was observed by the Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI) mounted on the NASA/ESA/CSA James Webb Space Telescope. As their names suggest, NIRCam and MIRI probe different parts of the electromagnetic spectrum. This allows the instruments to observe different components of the same galaxy, with MIRI especially sensitive to its gas-rich regions (the yellow swirls in this image) and NIRCam suitable for observing its densely packed field of stars.
Surpassing scientific expectations and exceeding its planned life in orbit, the Aeolus wind mission has been hailed as one of ESA’s most successful Earth observation missions. And now, its end will go down in history too, thanks to the ingenuity of the Agency’s mission control team who guided this remarkable satellite down to Earth’s atmosphere for a safe reentry.
