00:03:50
On 25 March, the first two satellites of the Celeste in-orbit demonstration mission will lift off aboard Rocket Lab’s Electron rocket from the company’s Māhia Launch Complex in New Zealand.
Celeste will play a pioneering role in elevating the future of Europe’s satellite navigation capabilities.
As ESA’s initiative for satellite navigation in low Earth orbit (LEO-PNT), the mission will be testing next-generation technologies and add new frequency bands for satellite navigation to inform the deployment of a future European operational navigation system in low Earth orbit.
The mission will begin with two demonstrator satellites, IOD1-2, to secure and test the
Tracking Arctic freshwater flow from space
Arctic rivers and runoff from the land pour vast volumes of freshwater into the Arctic Ocean, influencing seawater salinity, sea-ice formation and ocean circulation, thereby playing an important role in regulating Earth’s heat balance.
As northern monitoring networks decline, scientists have turned to satellite data to reconstruct two decades of river discharge and runoff, revealing a striking mosaic of regional change as warming temperatures and shifting precipitation patterns reshape the Arctic’s hydrological system in uneven and unexpected ways.
