Following on from the launch of the first Meteosat Third Generation weather satellite, MTG-I1, last December, the focus is now on getting its partner satellite, MTG-S1, ready for liftoff next year – and a significant milestone has been reached. The satellite has been equipped with its main instrument, the Infrared Sounder, hence the satellite’s name, and also the Copernicus Sentinel-4 instrument, an ultraviolet, visible, near-infrared light spectrometer, or UVN for short.

Image: The Artemis II astronauts, set to launch on a trip around the Moon next year, stand in front of the Orion spacecraft’s European Service Module-2 (ESM-2) that will provide everything they need to thrive on their voyage to Earth’s natural satellite. From left, the skilled crew is composed of NASA’s Victor Glover, Canadian Space Agency’s Jeremy Hansen, and NASA’s Christina Koch and Reid Wiseman. Their collective experience underscores the collaborative essence of space exploration, as they prepare for the challenges of deep space travel and return. The European Service Module-2 will provide crucial life support and necessary resources – water, air, electricity, com…

The smallest radar to fly in space has been delivered to ESA for integration aboard the miniature Juventas CubeSat, part of ESA’s Hera mission for planetary defence. The radar will perform the first radar imaging of an asteroid, peering deep beneath the surface of Dimorphos – the Great Pyramid-sized body whose orbit was shifted last year by the impact of NASA’s DART spacecraft.

Video: 00:03:31 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. But dealing with the huge and detailed set of novel data that Euclid observations will produce is not an easy task. To prepare for this, scientists in the Euclid Consortium have developed one of the most accurate and comprehensive computer simulations of the large-scale structure of…

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. View the full article

Video: 00:02:01 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 audio comes from the camera itself that was clamped to a steel cable on a northern ramp surrounding the Ariane 5 flame trench – about 50 m from the ZL3 launchpad. Despite being so close the camera was only protected against the humidity and rain in French Guiana. A solar panel provided extra power to the camera as it had to record for long time to capture the liftoff – no people are allowed so close to the launchpad during the countdown and blastoff…

Video: 00:04:59 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. While wildfires are a natural part of many ecosystems, scientists have warned that they are becoming more frequent and more widespread. In response, an upgraded version of ESA’s World Fire Atlas is now available providing a detailed analysis of wildfires across the globe. View the full article

Video: 00:01:35 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 week-long series of manoeuvres led to this point. They had never been performed before and pushed the satellite to its limits. Aeolus was never designed to fly at such low altitudes – its thrusters and fuel reserves were not made to operate in the thick lower reaches of Earth’s atmosphere. Despite …
