Olympus Mons and hence lead to the low gradients on the surface of the planet. Olympus Mons is an unlikely landing location for automated space probes in the near future. The high elevations preclude parachute-assisted landings because the atmosphere is insufficiently dense to slow the spacecraft down. Moreover, Olympus Mons stands in one of the dustiest regions of Mars. A mantle of fine dust obscures the underlying bedrock, possibly making rock samples hard to come by and likely posing a significant obstacle for rovers. Olympus Mons is the result of many thousands of highly fluid, basaltic lava flows that poured from volcanic
Doom Mons Doom Mons Doom Mons is the name of a mountain range and its eponymous peak on Titan, the largest moon of Saturn. A putative cryovolcano, it is the largest mountain range on Titan by volume, and its 1.45 km-high peak one of the highest. It was discovered by the "Cassini–Huygens" probe in 2005 and officially named in 2012. Doom Mons is located in the Southern Hemisphere of Titan, between 14-15° south and 40-41° west. It is located within the Aztlan darklands region, possibly connected to the wider Shangri-La dark region, and is adjacent to Sotra Patera, a possible cryovolcanic caldera
