Mega-constellation coverage

Satellite navigation is headed closer to users. ESA’s Navigation Directorate is planning an in-orbit demonstration with new navigation satellites that will orbit just a few hundred kilometres up in space, supplementing Europe’s 23 222-km-distant Galileo satellites. Operating added-value signals, these novel so-called ‘LEO-PNT’ satellites will investigate a new multi-layer satnav system-of-systems approach to deliver seamless Positioning, Navigation and Timing services that are much more accurate, robust and available everywhere.

      As the new Biomass satellite settles into life in orbit following its launch on 29 April, ESA has released its most extensive satellite-based maps of above-ground forest carbon to date. Spanning nearly two decades, the dataset offers the clearest global picture yet of how forest carbon stocks have changed over time.
      Developed through ESA’s Climate Change Initiative, this new long-term record integrates data from multiple satellite missions – and will soon be further enhanced by data from the Biomass mission itself.

      A Volvo Crawler Excavator severs the airframe, separating the tail section from the fuselage, of the modified C-141 Kuiper Airborne Observatory at Moffett Field, California.NASA The planned deconstruction, disposal, and preservation of historic parts of NASA’s decommissioned Kuiper Airborne Observatory is complete. Part of the airborne astronomy legacy of NASA’s Ames Research Center in California’s Silicon Valley, Kuiper conducted more than two decades of astronomical observations from 1975 to 1995. Later this year, the Kuiper cockpit will go on display at the Pima Air & Space Museum in Pima, Arizona, where NASA’s retired SOFIA (Stratospheric Observatory for Infrared Astronomy) aircraft is located, while its telescope will go on display at the Moffett Field Museum in the NASA Research Park.

      Video: 00:02:01 ESA’s state-of-the-art Biomass satellite has launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).
      In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.
      Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.
