Space Force cancels OCX, ending 15-year GPS ground-control effort with RTX; Lockheed wins follow-on AEP work

The U.S. Space Force and Pentagon have formally terminated the Next Generation Operational Control System (OCX), ending a 15-year program to modernize ground-control for the GPS constellation after risk and long delays. The cancellation scraps RTX’s ground-control network contract, with Lockheed awarded $105 million for the AEP effort.

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.
