ESA has signed contracts for two parallel concept studies for commercial-scale Space-Based Solar Power plants, representing a crucial step in the Agency’s new SOLARIS initiative – maturing the feasibility of gathering solar energy from space for terrestrial clean energy needs.
ESA’s Jupiter Icy Moons Explorer (Juice) has taken its first monitoring camera images showing part of the spacecraft with Earth as a stunning backdrop.
ESA’s Jupiter Icy Moons Explorer (Juice) lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana at 14:14 CEST on 14 April. The successful launch marks the beginning of an ambitious voyage to uncover the secrets of the ocean worlds around giant planet Jupiter.

ESA’s latest interplanetary mission, Juice, lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, at 14:14 CEST on 14 April 2023 to begin its eight-year journey to Jupiter, where it will study in detail the gas giant planet’s three large ocean-bearing moons: Ganymede, Callisto and Europa.
Data from ESA’s star-mapping Gaia spacecraft has allowed astronomers to image a gigantic exoplanet using Japan's Subaru Telescope. This world is the first confirmed exoplanet found by Gaia’s ability to sense the gravitational tug or ‘wobble’ a planet induces on its star. And the technique points the way to the future of direct exoplanet imaging.

At ESA’s mission control, before the launch comes the pre-launch briefing – and the all-important group photo. This is the team that will fly Juice to Jupiter with four planetary flybys of Earth and Venus, then switching orbit from Jupiter to its largest moon, Ganymede, followed by a tour of the icy, complex Jovian system comprising a whopping 35 lunar flybys.
A key focus of ESA’s Jupiter Icy Moons Explorer (Juice) will be Ganymede: Jupiter’s largest moon, and an ideal natural laboratory for studying the icy worlds of the Solar System.

Have you ever wondered what a volcano looks like from space? Today, we’re counting down our picks of the most impressive volcanoes around the world – captured by satellites. Our countdown includes Mount Fuji, Mount Mayon and Mount Vesuvius. Satellites orbiting 800 km above us can monitor volcanoes. They can provide real-time data on volcanic activity and can even help disaster response efforts post-eruption.
The explosion of a star is a dramatic event, but the remains that the star leaves behind can be even more dramatic. A new mid-infrared image from NASA’s James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion 340 years ago.
A large mass of Sargassum ‘seaweed’ circling around the Gulf of Mexico may soon wash up along the US west coast near Florida – depending on the right combination of currents and wind. The bloom, which may likely be the largest ever recorded, is so large that it’s visible from space.

New research reveals that ice being lost from glaciers that flow into lakes in the Himalayas has been significantly underestimated. This discovery has critical implications for predicting the demise of the region’s glaciers and for managing critical water resources.

After months practicing with a ‘fake’ Juice spacecraft, teams at ESA’s mission control centre in Darmstadt, Germany, today got in touch with the real thing. For the first time, mission engineers connected to the Ariane 5 rocket and inside its fairing the Juice spacecraft, for a dress rehearsal of the all-important “network countdown”.

ESA’s JUpiter ICy moons Explorer (Juice) will launch from Europe’s Spaceport at Kourou in French Guiana on Thursday 13 April 2023. Watch the replay of this online media briefing to hear more about the mission and the launch itself. Participants will include Olivier Witasse, Juice Project Scientist ; Ruedeger Albat, Head of Ariane 5 Programme at ESA and Alessandro Atzei, Payload System Engineer.
