Today, Mars is believed to be largely tectonically inactive. However, observational evidence and its interpretation suggests that this was not the case further back in Mars's geological history. At the scale of the whole planet, two large scale physiographic features are apparent on the surface. The first is that the northern hemisphere of the ...
Martian dust devil photographed by the Mars Reconnaissance Orbiter. This dust devil is 800 m (2,600 ft) tall and 30 m (98 ft) wide. This dust devil is 800 m (2,600 ft) tall and 30 m (98 ft) wide. The existence of dust devils on Mars was confirmed by analysis of data from the Viking probes in the early 1980s.
Two NASA spacecraft at Mars — one on the surface and the other in orbit — have recorded the biggest meteor strikes and impact craters yet. The high-speed barrages last year sent seismic waves ...
NASA's InSight lander is fighting a layer of Mars dust that's covering its solar panels and causing a power shortage. Still, it made a big discovery. Wavering NASA lander detects biggest Mars ...
Stickney is the largest crater on Phobos, which is a satellite of Mars. It is 9 km (5.6 mi) in diameter, taking up a substantial proportion of the moon's surface. It is 9 km (5.6 mi) in diameter, taking up a substantial proportion of the moon's surface.
On May 4, 2022, NASA's InSight lander detected the largest quake yet recorded on Mars, one with a 4.7 magnitude - fairly modest by Earth standards but strong for our planetary neighbor. Given Mars ...
The first meteor photographed on Mars (on March 7, 2004, by the Spirit rover) is now believed to have been part of a meteor shower whose parent body was comet 114P/Wiseman-Skiff. Because the radiant was in the constellation Cepheus , this meteor shower could be dubbed the Martian Cepheids.
