Video: 00:00:57 A stunning sequence of 89 images taken by the monitoring cameras on board the European-Japanese BepiColombo mission to Mercury, as the spacecraft made a close approach of Venus on 10 August 2021. The sequence includes images from all three Monitoring Cameras (MCAM) onboard the Mercury Transfer Module, which provides black-and-white snapshots in 1024 x 1024 pixel resolution. It is not possible to image with the high-resolution camera suite during the cruise phase. The images have been lightly processed to enhance contrast and use the full dynamic range. A small amount of optical vignetting is seen in the corners of some of the images. The first imag…

Video: 00:03:21 Meet bag, bottle and straw, three bits of plastic left on the beach. They are only small, but they are heading into the ocean, where they could cause big damage. ESA is exploring how satellites can help detect and reduce plastic pollution in the ocean. From spotting build-ups of marine litter to tracking ocean currents, satellites could be game-changing in tackling this enormous environmental problem. Though engaging for children and adults alike, this video is designed with 8–12-year-olds in mind. In particular, teachers can use it to introduce the topic of marine litter in subjects such as geography and science. A Dutch version will be available …

Video: 00:09:41 The International Space Station Expedition 65 crew recorded themselves on a day off after a long week of work having some weightless fun. From Earth orbit, 400 km above our planet, the crew present the very first Space Olympics. ESA astronaut Thomas Pesquet shared this video on social media with the caption: “The first ever Space Olympics ! A Saturday afternoon on the International Space Station. Four disciplines. Rules that evolved as we played. Seven athletes. Four nations. Two teams. Crew cohesion and morale boosted like never before. The first Space Olympics saw Team Crew Dragon and Team Soyuz compete in lack-of-floor-routine, no-handball, sync…

With the first Copernicus Sentinel-2 satellite in orbit since 2015 and the second since 2017, engineers are busy preparing the mission’s follow-on pair to eventually pick up the baton to supply images for a myriad of applications from food security to monitoring the decline of Earth’s ice. Slated for launch at the beginning of 2024, Sentinel-2C has just started a punishing five-month testing programme to ensure that it is fit for its life in space. View the full article

Forests are not only key to moderating our climate by sequestering atmospheric carbon, but they also create a cooling effect by increasing low-level cloud. A first global assessment using satellite observations has shown that for two-thirds of the world, afforestation increases low-level cloud cover, with the effect being strongest over evergreen needleleaf forest.

Russia has the largest area of forest on the planet, with more than a fifth of the world's trees. A new study, led by Russian scientists using data from ESA’s Climate Change Initiative, has produced new estimates of biomass contained in Russian forests, and confirms that the vast forested area is storing more carbon than previously estimated.

Video: 00:04:00 ESA's Jupiter Icy moons Explorer, Juice, has successfully completed rigorous thermal tests simulating the extreme coldness of space and the warmth of the Sun at ESA’s test centre ESTEC, in The Netherlands. The spacecraft underwent a month of round-the-clock testing and monitoring in the Large Space Simulator, which recreates the vacuum of space and is able to simulate both hot and cold space environments. The spacecraft was subjected to temperatures ranging from 250 degrees to minus 180 degrees Celsius, showing that it can survive its journey in space. Juice will launch in 2022 to our Solar System’s largest planet. It will spend over four years stu…

Image: For the first time, astronomers have seen light coming from behind a black hole. Using ESA’s XMM-Newton and NASA’s NuSTAR space telescopes, an international team of scientists led by Dan Wilkins of Stanford University in the USA observed extremely bright flares of X-ray light coming from around a black hole. The X-ray flares echoed off of the gas falling into the black hole, and as the flares were subsiding, the telescopes picked up fainter flashes, which were the echoes of the flares bouncing off the gas behind the black hole. This supermassive black hole is 10 million times as massive as our Sun and located in the centre of a nearby spiral galaxy called I Zwic…
