Since 2016, ESA’s Space Debris Office has published an annual Space Environment Report to provide a transparent overview of global space activities and determine how well these and other international debris-reduction measures are improving the long-term sustainability of spaceflight.
Each year on 22 April, people across the planet join forces to raise awareness about the depleting quality of the environment, the unequivocal effects of climate change and the importance of protecting our planet for future generations. We celebrate Earth Day every day at ESA. This week, this spectacular image of Earth is brought to you by the Meteosat Second Generation series of missions.
If man’s best friend is a dog, then in the future astronauts’ closest companions might well be rovers. A technique allowing astronauts in orbit to control rovers exploring planetary surfaces has been developed by a research team from ESA, the German Aerospace Center DLR and European academia and industry, culminating in an Earth-based rover session commanded from the International Space Station. A paper published in the prestigious Science Robotics journal this week details their results.
The test version of a unique satellite navigation receiver has been delivered for integration testing on the Lunar Pathfinder spacecraft. The NaviMoon satnav receiver is designed to perform the farthest ever positioning fix from Earth, employing signals that will be millions of times fainter than those used by our smartphones or cars.
As one of the last milestones before liftoff at the end of the year, the first Meteosat Third Generation weather satellite is being fitted with its Lightning Imager. From geostationary orbit, 36 000 km above Earth’s surface, this state-of-the-art European instrument will continuously monitor lightning over more than 80% of Earth’s disc for early warnings of dangerous storms. Remarkably, it is capable of imaging relatively weak lightning events in full sunlight.

Europe’s Spaceport in French Guiana is preparing for the arrival of Ariane 6, ESA’s new heavy-lift rocket. The latest round of testing aims to validate the system of fuel lines and mechanical supporting arms that will keep Ariane 6 topped up with liquid hydrogen and liquid oxygen in the critical moments before liftoff. This work is part of the final preparations of the new Ariane 6 launch complex and all the systems necessary for a launch.
The Copernicus Sentinel-3 mission captured this impressive shot of the almost cloud-free Scandinavian Peninsula on 20 March.

A satisfying, audible ‘pop’ marked a successful piercing of the sealed Apollo 17 sample container using the ESA designed and built piercing tool. The tool forms part of a gas sampling system with a gas extraction manifold, designed and built by Washington University St Louis, USA.
With the climate crisis continuing to tighten its grip, nations around the world are making efforts to reduce emissions of climate warming gases. To track action, countries report their greenhouse gas emissions to the UNFCCC – the body responsible for driving global action to combat climate change. While accurate and consistent reporting is crucial, very few countries exploit Earth observation satellite data to check and improve their estimates. Scientists have now devised new ways of comparing national greenhouse gas inventories with independent measurements taken from space.

ESA Director General Josef Aschbacher shares the outcome of the ESA Council extraordinary meeting in this virtual Q&A with journalists. Additional updates are provided on ESA’s main programmes, the overall rollout of Agenda 2025 on the way to the ESA Ministerial Meeting in November 2022 as well as further implications of the current geopolitical situation on ESA’s activities.
With help from a cryocooler, Webb's Mid-Infrared Instrument has dropped down to just a few degrees above the lowest temperature matter can reach and is ready for calibration.

Watch the replay of our live Q&A media session (In English and Italian) with ESA astronaut Samantha Cristoforetti.
After decades of drought, water levels in Lake Powell, the second-largest humanmade reservoir in the United States, have shrunk to its lowest level since it was created more than 50 years ago, threatening millions of people who rely on its water supply. Satellite images allow us to take a closer look at the dwindling water levels of the lake amidst the climate crisis.
Tune in this Monday 11 April from 15:00-16:30 CEST (13:00-14:30 GMT) for a conversation between ESA astronaut Samantha Cristoforetti and media in Europe live on ESA Web TV.
