Video: 00:04:29 Watch the second episode of the ExoMars Rosalind Franklin rover mission – Europe’s ambitious exploration journey to search for past and present signs of life on Mars. This episode starts with Rosalind searching for traces of life below the martian surface using a ground penetrating radar and a set of cameras. The rover will dig, collect, and investigate the chemical composition of material collected by a drill. Rosalind Franklin will be the first rover to reach a depth of up to two metres deep below the surface, acquiring samples that have been protected from surface radiation and extreme temperatures. Rosalind Franklin uses the WISDOM radar to hel…

The Global Methane Budget 2024 paints a troubling picture of the current state of global methane emissions. The new report, which uses data from the Copernicus Sentinel-5P satellite, reveals that human activities are now responsible for at least two-thirds of global methane emissions. This marks a significant increase in human-produced methane sources over the past two decades, with emissions rising by 20%, with the fastest rise occurring over the last five years.

The first satellite in ESA’s Cluster quartet safely came back down to Earth last night in a world-first ‘targeted reentry’, marking a brilliant end to this remarkable mission. The spacecraft, dubbed ‘Salsa’ (Cluster 2), reentered Earth’s atmosphere at 20:47 CEST on 8 September 2024 over the South Pacific Ocean. In this region, any risk of fragments reaching land are absolutely minimised. During the last two decades Cluster has spent in space, it has provided invaluable data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast space weather. With this first-ever targeted reentry, Cluster will go down in history for a second reason…

Video: 00:06:50 The first of four satellites that make up ESA’s Cluster mission is coming safely back down to Earth, marking a brilliant end to this remarkable mission. The satellite’s orbit was tweaked back in January to target a region as far as possible from populated regions. This ensures that any spacecraft parts that survive the reentry will fall over open ocean. During 24 years in space, Cluster has sent back precious data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast potentially dangerous space weather. With this first ever targeted reentry, Cluster goes down in history for a different reason, taking ESA w…

Video: 00:01:00 Rover trials in a quarry in the UK showing a four-wheeled rover, known as Codi, using its robotic arm and a powerful computer vision system to pick up sample tubes. The rover drives to the samples with an accuracy of 10cm, constantly mapping the terrain. Codi uses its arm and four cameras to locate the sample tube, retrieve it and safely store it on the rover – all of it without human intervention. At every stop, the rover uses stereo cameras to build up a 180-degree map of the surroundings and plan its next maneouvres. Once parked, the camera on top of the mast detects the tube and estimates its position with respect to the rover. The robotic arm…

In 2022 NASA’s DART spacecraft made history, and changed the Solar System forever, by impacting the Dimorphos asteroid and measurably shifting its orbit around the larger Didymos asteroid. In the process a plume of debris was thrown out into space. The latest modelling, available on the preprint server arXiv and accepted for publication in the September volume of The Planetary Science Journal, shows how small meteoroids from that debris could eventually reach both Mars and Earth – potentially in an observable (although quite safe) manner.

Image: ESA’s Metal 3D Printer has produced the first metal part ever created in space. The technology demonstrator, built by Airbus and its partners, was launched to the International Space Station at the start of this year, where ESA astronaut Andreas Mogensen installed the payload in the European Drawer Rack of ESA’s Columbus module. In August, the printer successfully printed the first 3D metal shape in space. This product, along with three others planned during the rest of the experiment, will return to Earth for quality analysis: two of the samples will go to ESA’s technical heart in the Netherlands (ESTEC), another will go to ESA’s astronaut training centre in…

The two new Galileo satellites launched in April have entered service, completing the second of three constellation planes. With every addition to the constellation, the precision, availability and robustness of the Galileo signal is improved. The next launch is planned in the coming weeks and the remaining six Galileo First Generation satellites will join the constellation in the next years. View the full article

The ESA/JAXA BepiColombo mission has successfully completed its fourth of six gravity assist flybys at Mercury, capturing images of two special impact craters as it uses the little planet’s gravity to steer itself on course to enter orbit around Mercury in November 2026. The closest approach took place at 23:48 CEST (21:48 UTC) on 4 September 2024, with BepiColombo coming down to around 165 km above the planet’s surface. For the first time, the spacecraft had a clear view of Mercury’s south pole. View the full article

Video: 00:14:09 The Copernicus Sentinel-2C satellite lifted off on 5 September at 03:50 CEST (4 September 22:50 local time) aboard the last Vega rocket, flight VV24, from Europe’s Spaceport in French Guiana. Sentinel-2C will continue the legacy of delivering high-resolution data that are essential to Copernicus – the Earth observation component of the EU Space Programme. Developed, built and operated by ESA, the Copernicus Sentinel-2 mission provides high-resolution optical imagery for a wide range of applications including land, water and atmospheric monitoring. Sentinel-2C was the last liftoff for the Vega rocket – after 12 years of service this was the final fl…

The third Copernicus Sentinel-2 satellite launched today aboard the final Vega rocket from Europe’s Spaceport in French Guiana. Sentinel-2C will continue providing high-resolution data that is essential to Copernicus – Europe’s world leading Earth observation programme. Sentinel-2C launched into orbit on 5 September at 03:50 CEST (4 September 22:50 local time) and separated from the Vega rocket at approximately 04:48 CEST. View the full article

According to recent research, Europe’s net greenhouse gas emissions have decreased by around 25% since the 1990s. While this is good news, the study also revealed a weakening in the capacity of land and vegetation to absorb and store atmospheric carbon. View the full article

Teams from across ESA and industry have worked continuously over the past four months to overcome a glitch that prevented BepiColombo’s thrusters from operating at full power. The ESA/JAXA mission is still on track, with a new trajectory that will take it just 165 km from Mercury’s surface on Wednesday. Taking BepiColombo closer to Mercury than it’s ever been before, this flyby will reduce the spacecraft’s speed and change its direction. It also gives us the opportunity to snap images and fine-tune science instrument operations at Mercury before the main mission begins. Closest approach is scheduled for 23:48 CEST (21:48 UTC) on 4 September. View the full article

Video: 00:02:32 Sentinel-2C is ready for launch! The new satellite will soon join its Copernicus Sentinel-2 family in orbit – where it will continue to provide detailed views of Earth’s land and coastal waters. The mission is based on a constellation of two identical satellites: Sentinel-2A and Sentinel-2B. The constellation was originally designed to monitor land surfaces – but its scope has since expanded. It now covers a wide range of applications including deforestation, water quality, monitoring natural disasters, methane emissions and much more. Sentinel-2C, once in orbit, will replace the Sentinel-2A unit – prolonging the life of the Sentinel-2 mission – en…
