Hubble celebrates 35 years in orbit with 4 stunning new images! ✨In celebration of the NASA/ESA Hubble Space Telescope’s 35 years in Earth orbit, an assortment of images that were recently taken by Hubble has been released today. This stretches from the planet Mars to images of stellar birth and death, and a magnificent neighbouring galaxy. After over three decades of scrutinising our Universe, Hubble remains a household word as the most well-recognised telescope in scientific histor...

The satellite that sees through forests | Biomass missionESA’s state-of-the-art Biomass mission is designed to provide new insights into the health and evolution of the world’s forests, helping us understand how they are changing over time and, importantly, their critical role in the global carbon cycle. Equipped with the first-ever fully polarimetric P-band synthetic aperture radar, this satellite can penetrate dense forest canopies. The long 70 cm wavelength of the radar enables it...

Arnaud Prost | Sky, Sea, Space | ESA Explores #12Meet Arnaud Prost—aerospace engineer, professional diver, and member of ESA’s Astronaut Reserve. From flying aircraft to getting a taste of spacewalk simulation, his passion for exploration knows no bounds. In this miniseries, we take you on a journey through the ESA Astronaut Reserve, diving into the first part of their Astronaut Reserve Training (ART) at the European Astronaut Centre (EAC) near Cologne, Germany. Our “ARTists” ar...
The people make the mission.
Two spacecraft. One shadow. Zero ground control.
Let’s fuel a satellite! ⛽️This video shows the precise and delicate process of loading the Biomass satellite with 132 kg of highly volatile fuel. This fuel will power the satellite so that it can carry out the complex manoeuvres that are needed during its mission.
Timelapse of Hera's Mars flybyOn 12 March 2025, ESA’s Hera spacecraft soared just 5000 km above Mars and passed within 300 km of its distant moon, Deimos. Captured by Hera’s 1020x1020 pixel Asteroid Framing Camera, this video sequence offers a rare view of the red planet and its enigmatic moon. The original greyscale images have been colour-enhanced based on known surface features. Learn more: https://www.esa.int/Space_Safety/Hera/Hera_asteroid_mission_spies_Mars_s_Deimos_moon Cred...

Will asteroid 2024 YR4 hit the Moon? ☄️On December 22, 2032, a 60-metre asteroid might crash into the Moon. Scientists have been tracking asteroid 2024 YR4, and while we now know that it won’t hit Earth, there’s currently about a 4% chance it could smash into the lunar surface. If that happens, it’ll be a rare chance to watch a big space rock leave its mark on our cosmic neighbour in real time. But we aren't just sitting around waiting. We’ve been keeping an eye on lunar im...
Ever wondered what it takes to train for space?
How hidden lakes threaten Antarctic Ice Sheet stabilityThere is a series of lakes beneath Thwaites Glacier, part of an extensive network of meltwater drainage channels. In 2013, seven subglacial lakes, that were more than 2 km beneath Thwaites Glacier, suddenly all drained at the same time, releasing around 7 cubic kilometres of freshwater into the Amundsen Sea. The new research, based on CryoSat data and published in Nature Communications, underscores the Antarctic ice sheet’s sensit...
Space Debris: Is it a Crisis?The European Space Agency’s short documentary film ‘Space Debris: Is it a Crisis?’ on the state of space debris premiered at the 9th European Conference on Space Debris on 1 Apr 2025. Earth is surrounded by thousands of satellites carrying out important work to provide telecommunications and navigation services, help us understand our climate, and answer fundamental questions about the Universe. However, as our use of space accelerates like never befo...
