NASA satellite reentry to exceed agency risk limits after late-stage design changes

Late-stage design changes to a NASA satellite increased the likelihood of an uncontrolled reentry and pushed the mission’s modeled ground-casualty risk above agency safety limits, agency documents say. The breach of NASA thresholds requires further assessment of reentry behavior and possible risk-reduction measures.

Starlab Space sells out commercial payload capacity ahead of NASA's next LEO program phase Starlab Space has fully booked the commercial payload capacity on its planned low‑Earth‑orbit station, locking in customer manifests as it awaits the next phase of NASA's LEO program that will guide agency engagement and scheduling. The sell‑out underscores commercial demand for private orbital platforms.

Scientists decode the Sun’s 'heartbeat' — 40 years of helioseismology reveal internal shifts between solar cycles Using 40 years of telescope observations, researchers at the University of Birmingham and Yale have decoded the Sun's 'heartbeat', showing the star's internal structure shifts measurably between solar cycles, leaving fingerprints deep beneath the surface. The finding could improve forecasting of space weather and its terrestrial impacts.

Suspended NOAA satellite chief warns staffing cuts have 'lobotomized' federal science and threaten satellite programs The head of NOAA’s satellite unit—on administrative leave for months—warned that workforce reductions have "lobotomized" federal science, endangering NOAA's satellite programs and operational data streams. His remarks underscore internal leadership turmoil and potential impacts to continuity of earth-observing services.

NASA selects Centaur V to replace Exploration Upper Stage on SLS in major Artemis shake-up NASA has chosen ULA’s Centaur V to replace the Exploration Upper Stage on the Space Launch System, reconfiguring future Artemis missions. Centaur V — currently flown on ULA’s Vulcan — will become the SLS's new upper stage, marking a major change to the rocket's architecture and suppliers.

Starliner and Artemis: commercial label vs. commercial discipline A critical look at how the “commercial” label is applied to NASA’s Starliner crew taxi and the Artemis program, and whether that branding aligns with the programmatic rigor needed for complex human-spaceflight missions. The piece contrasts rhetoric with operational and contractual discipline.

Dimorphos shows first direct evidence of material transfer between binary asteroids University of Maryland researchers found fan-like patterns on Dimorphos, the asteroid hit by NASA’s DART mission, that are not imaging artifacts but the first direct evidence of material transfer between binary asteroids. Image correction, modelling and laboratory experiments reproduced the features and confirmed physical transfer.

Mars advocates: NASA's lunar return can advance crewed Mars goals Mars mission proponents say NASA's renewed human-return-to-Moon program can be leveraged as a practical stepping stone toward eventual crewed Mars missions, providing a near-term arena to develop and validate systems, operations and programmatic pathways needed for longer-duration interplanetary exploration.
