The Solar System’s small, rocky innermost world
A series of high-altitude eclipse observations are under way across Europe, North America and beyond. NASA-backed aircraft chase the moon’s shadow to extend totality, while airlines offer special flights and Iberia livestreams the event from Spain.
A NASA-backed mission to salvage the Swift telescope using the three-armed Link spacecraft has failed to boost Swift to a higher orbit. Link has run low on fuel after a close approach and will reenter the atmosphere in coming weeks as NASA notes the mission offers lessons for future renewals of space assets.
Independent reports NASA and ESA push two major space initiatives: Envision aims to map Venus at unprecedented radar resolution to probe active volcanism; BepiColombo edges toward Mercury with a dramatic orbit insertion after nine gravity assists and separation of its propulsion module.
Scientists have identified a 222‑metre‑wide, up to 43‑metre‑deep crater on the Moon formed in spring 2024 and first spotted in LRO images in 2025. The impact churned material across more than 100 km, produced a roughly 7‑km cold spot and has provided rare data scientists say will inform risk assessments for planned lunar bases.
