eROSITA disentangles Solar System soft X-ray emission, clarifying its impact on the X-ray sky Using the eROSITA space telescope, MPE researchers have isolated the X-ray glow originating within the Solar System and quantified how it contributes to the observed soft X-ray sky. The result improves interpretation of diffuse X-ray backgrounds and separates local emission from astrophysical sources.

US Space Force cancels RTX OCX GPS ground-control program after years of delays, cost overruns The U.S. Space Force has canceled the multibillion-dollar Next-Generation GPS Operational Control Segment (OCX) contract previously awarded to RTX, ending a long-running effort that the service says suffered major delays and cost overruns. The Pentagon’s cancellation follows extensive speculation and leaves a gap in next-gen GPS ground-control modernization.

Josef Aschbacher at Space Symposium 2026: Copernicus-driven “economy” meets a 350TB/day data scaling gap ESA DG Josef Aschbacher told Space Symposium 2026 that Europe’s competitiveness in the global space ecosystem now hinges on closing a rapid scaling gap in data generation and exploitation. The discussion connected Copernicus’ growth expectations—framed as 350TB/day—to the policy, industrial and service changes ESA says Europe must deliver.
