We used attitude data from the Mars Ingenuity helicopter with a simple steady-state model to estimate windspeeds and directions at altitudes of 3 meters up to 24 meters, the first […]
This chapter presents a comprehensive overview of the abundances and distribution of S, and the processes that control the behavior of S on the Earth’s Moon and on Mercury. The […]
A new paper published in Icarus describes, maps and dates how glaciers and glacial runoff sculpted the northeastern rim of Mars’ Hellas basin over the last 3 billion years. The […]
Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA’s Mars Express. This […]
Remote-sensing images of Mars contain rich information about its surface morphology, topography, and geological structure. These data are fundamental for scientific research and exploration missions of Mars.
Sitting in the middle of a vast landscape, bordered by a ridge and filled with loose rocks, Lauren Edgar held a hand lens to her eye as she peered at […]
Europa, the second inner Jovian Galilean satellite, is believed to contain a global liquid water ocean covered by an ice shell likely 10s of kilometers thick. The paucity of impact […]
The crew of Schmidt Ocean Institute’s research vessel Falkor (too) discovered four underwater mountains — the tallest of which is over 1.5 miles high — on a January transit from […]
Direct geological evidence of recent volcanic activity on Venus has been observed for a second time. Scientists in Italy analyzed archival data from NASA’s Magellan mission to reveal surface changes […]
At least twice in the last 20 years, nuclear submarines have collided with previously unknown underwater mountains called seamounts. The reason: they were not on any nautical charts. Just last […]
