Fly over Xanthe Terra with Mars Express

ESA’s Mars Express takes us on another mesmerising flight over curving channels carved by water, islands that have resisted erosion, and a maze of hilly terrain.
Central to the tour is a 1300 km-long outflow channel called Shalbatana Vallis. It cascades down from the highland region of Xanthe Terra to the smoother lowlands of Chryse Planitia.
Billions of years ago, water surged through this channel, creating many of the features we see today.
The tour culminates in a spectacular view of a 100 km-wide impact crater, smashed out of Mars’s surface when it collided with a space rock.
Enjoy the flight, and be

Moon rock study reshapes timeline of ancient lunar impacts
Thursday, 02 October 2025 06:04
When Apollo 17 astronauts returned with lunar rock sample 76535, they unknowingly carried back a fragment that would continue to puzzle scientists for decades. The rock formed nearly 50 kilometers below the Moon's surface yet shows little evidence of the violent shocks expected from such depths.
Many researchers assumed it was excavated by the colossal impact that created the South Pole-Ai Moonquakes drive most new lunar landslides since 2009
Thursday, 02 October 2025 06:04
A Chinese-led research team has identified 41 new landslides on the Moon since 2009, concluding that endogenic moonquakes, not fresh impacts, are the primary trigger. The finding redefines understanding of active surface processes and highlights geohazard risks for future lunar bases.
For decades, scientists debated whether lunar landslides stem mainly from internal seismic activity, impac Scalable lunar power study launched by Honda and Astrobotic
Thursday, 02 October 2025 06:04
Honda Motor Co. and Astrobotic Technology have entered a joint development agreement to investigate scalable lunar power solutions that combine Honda's regenerative fuel cell (RFC) system with Astrobotic's Vertical Solar Array Technology (VSAT) and LunaGrid service. The collaboration aims to deliver continuous and reliable power for extended lunar surface operations, particularly during the two- Evidence of a past, deep ocean on Uranian moon, Ariel
Thursday, 02 October 2025 06:04
Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus' moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and found that it may have once been over 100 miles (170 kilometers) deep. For perspective, the Pacific Ocean averages 2.5 miles (4 kilometers) deep.
"Ariel is pretty unique in terms of icy moons,"
