NASA's DART mission becomes first to alter an asteroid's orbit around the Sun Analysis of the 2022 DART impact on the binary system Didymos–Dimorphos shows the collision not only shortened Dimorphos's orbit around its larger companion but measurably changed the pair's heliocentric path — the first deliberate alteration of a celestial body's orbit around the Sun and a proof point for planetary defense.

Orion cleared for Artemis launch as NASA reshuffles rockets; lunar lander question remains NASA has reorganized its Artemis launch vehicles and confirms Orion is ready to fly on the upcoming Artemis mission, but the agency has not resolved who will provide a crewed lunar lander. The move advances the flight schedule while leaving surface access and contractor selection unsettled.

Century-long solar records reveal patterns to sharpen near-term solar-activity forecasts A new study reanalyzed more than a century of solar observations to uncover connections in sunspot and magnetic behavior that improve short-term predictions of solar activity. The work aims to reduce uncertainty in when solar storms and coronal mass ejections will occur, enhancing near-term space‑weather forecasting skill.

United Launch Alliance to build additional upper stages for NASA's SLS United Launch Alliance will build additional upper stages for NASA's Space Launch System, increasing ULA's production role in SLS sustainment. The decision adds hardware capacity for upcoming Artemis-class missions and shifts near-term workload and supplier demand onto ULA's manufacturing lines.
