Celeste’s first satellites launched to explore LEO-based satellite navigation
Saturday, 28 March 2026 10:07
On 28 March, the European Space Agency (ESA) took a major step forward in strengthening Europe's ambition for more resilient satellite navigation, as the first two satellites of the Celeste in-orbit demonstration mission lifted off from New Zealand aboard Rocket Lab’s Electron. Their mission is to begin testing a complementary low Earth orbit layer for Galileo.

At 10:14 CET on 28 March, the first two satellites of ESA’s Celeste LEO-PNT in-orbit demonstration mission lifted off aboard a Rocket Lab Electron rocket from Māhia, New Zealand.
Celeste is Europe’s first initiative to bring satellite navigation into low Earth orbit (LEO). By testing next-generation technologies and new frequency bands, it will help shape the future of positioning, navigation and timing services.
Flying closer to Earth, Celeste will demonstrate how a complementary LEO layer can strengthen Europe’s Galileo system in medium Earth orbit — improving resilience, enhancing performance and enabling new services.

Getting to the core of a medicane
Friday, 27 March 2026 10:21
Everyone knows what a hurricane is, but a lesser-known storm type – a medicane – recently made landfall in Libya. While the arrival of Medicane Jolina, a rare Mediterranean cyclone, brought extreme weather, it also provided scientists with a crucial test case.
Using different types of data from Earth-observing satellites, researchers are gaining new insights into how these storms form and evolve, and therefore, how their impacts can be predicted more accurately.
