Learn what NASA's multi-hour rollout of the SLS rocket and Orion capsule to Pad 39B at Kennedy means and why it is a key step toward the Artemis II mission with a four-member crew. We bring you who is participating, what is being tested on the pad, and how the wet dress rehearsal affects the final launch date decision.
Find out how the A23a iceberg, once the world’s largest, set off on a perilous journey from Antarctica to the South Atlantic after decades of inactivity. We tell the story of its breakup, the hidden melting processes, and what scientists are learning from satellite imagery.
Find out why ESA, after more than 10 years of operation, switched on Sentinel-2A during the night as well. We explain what the images of gas flares, fires and fishing vessels revealed and how Copernicus and the future Sentinel-2 Next Generation mission could gain a new tool for monitoring the sea, energy and urban lights.
Find out how the refreshed virtual tour of ESA’s Test Centre at ESTEC takes you through the chambers where satellites are put through vibrations, vacuum, and launch noise, and discover why EarthCARE, PLATO, and Smile had to pass through this Dutch laboratory before their trip to orbit—and how that process decides the success of every mission.
Find out how the Romanian company ATD Aerospace RS SRL, with ESA’s support, is developing a 10 kN restartable rocket engine with variable thrust for future European launches. We provide an overview of water-cooled tests, hypergolic propellants, and the role of the FLPP programme in developing reusable rocket stages.
Learn how Ariane 6 and the ASTRIS orbital vehicle are changing Europe’s approach to space, speeding satellites from transfer orbits to target orbits, saving fuel and extending spacecraft lifetimes, and opening new opportunities for commercial missions, constellations, and exploration of the Moon, deep space, and future missions.
