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…

ESA has successfully operated a spacecraft with Europe’s next-generation mission control system for the first time. The powerful software, named the 'European Ground System - Common Core' (EGS-CC), will be the ‘brain’ of all European spaceflight operations in the years to come, and promises new possibilities for how future missions will fly.

Long-term studies of ozone and water vapour in the atmosphere of Mars could lead to better understanding of atmospheric chemistry for the Earth. A new analysis of data from ESA's Mars Express mission has revealed that our knowledge of the way these atmospheric gases interact with each other is incomplete. View the full article
