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.
The Mars Global Surveyor, active from 1997 to 2006, was the first spacecraft able to image Mars in high enough resolution to detect new impacts, with a resolution of up to 1.5 meters (4.9 ft). The first detected impact, a 14.4-meter (47 ft)-diameter crater in southern Lucus Planum , happened between 27 January 2000, and 19 March 2001. [ 2 ]
The low detection rate and evaluation when the windspeed was low at the Viking 2 site, allowed limits to be placed on seismic activity on Mars. [10] [7] In 2013, data from the InSight mission (see below) led to an increased interest in the Viking data set, and further analysis may reveal one of the largest collections of Mars dust devil ...

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 ...
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.
