Mars Express has delivered the clearest orbital view yet of Schiaparelli Crater, the fictional landing site from The Martian. Stereo imaging combined with laser altimetry produced a three-dimensional surface model that reveals layered deposits and subtle rim structures at meter-scale resolution. The data let scientists compare present-day topography against earlier missions and track dust movement over time. The crater's floor shows textures consistent with ancient fluvial or aeolian processes. What surface changes will the next imaging pass detect?
Earth's largest dune fields can stretch hundreds of kilometers, yet the sand grains themselves are only a few hundred micrometers across—roughly the width of a human hair. On Mars the same grains travel under an atmosphere just one percent as dense, so winds must reach much higher speeds before they can move material; when they do, dunes grow taller and more widely spaced than any on Earth. Titan adds another twist: its dunes are made of frozen hydrocarbon particles rather than silicate sand, and they march across the surface at roughly the speed a child walks. The new global map shows that dune orientation on Earth faithfully records the direction of the strongest seasonal winds, giving planetary scientists a template they can apply to orbital images of Mars and Titan. The remaining puzzle is why some dune fields on Mars appear locked in place while others migrate steadily—what local wind or sediment supply difference keeps one field active and another frozen?
New orbital views and chemical detections keep adding texture to the picture of how planets and stars actually work.
