View looks downstream. Martian lava tubes are volcanic caverns on Mars that are believed to form as a result of fast-moving, basaltic lava flows associated with shield volcanism. [1] Lava tubes usually form when the external surface of the lava channels cools more quickly and forms a hardened crust over subsurface lava flows. [2]
Olympus Mons (/ əˌlɪmpəs ˈmɒnz, oʊ -/; [4] Latin for ' Mount Olympus ') is a large shield volcano on Mars. It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level. It is Mars's tallest volcano, its tallest planetary mountain ...

The Caves of Mars Project was an early 2000s program funded through Phase II [clarification needed] by the NASA Institute for Advanced Concepts [1 ...
The NASA Perseverance rover may have found a pivotal clue that’s central to its mission on Mars: geological evidence that could suggest life existed on the red planet billions of years ago. The ...
As of 2024, the database has 439 non-partisan organizations around the world. [6] [7] The Lab's inclusion criteria are based on whether the organization: [8] reviews statements by all parties and sides; examines discrete claims and reaches conclusions; transparently identifies its sources and explains its methods; discloses funding/affiliations;
NASA’s Perseverance rover is tackling a steep new challenge on Mars. The rover will go up 1,000 feet (305 meters) to the rim of Jezero Crater to dig up rock samples. Since landing on the red ...
Volcanism is a process in which magma from a planet's interior rises through the crust and erupts on the surface. The erupted materials consist of molten rock (lava), hot fragmental debris (tephra or ash), and gases. Volcanism is a principal way that planets release their internal heat. Volcanic eruptions produce distinctive landforms, rock ...
