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 ...
Caves of Mars Project. THEMIS image of probable cave entrances on Arsia Mons. The pits have been informally named (A) Dena, (B) Chloe, (C) Wendy, (D) Annie, (E) Abby (left) and Nikki, and (F) Jeanne. The Caves of Mars Project was an early 2000s program funded through Phase II [clarification needed] by the NASA Institute for Advanced Concepts [1 ...
Scholarly analysis of Trump's tweets found "significant evidence" of an intent to deceive. [15] By June 2019, after initially resisting, many news organizations began to describe some of his falsehoods as "lies". [16] The Washington Post said his frequent repetition of claims he knew to be false amounted to a campaign based on disinformation. [17]
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 ...
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 ...
Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
The base of the volcano is buried by young (Amazonian-aged) lava flows presumably from the Tharsis Montes, so the true size of the edifice cannot be accurately determined. Estimates of the thickness of lava burying the base of Tharsis Tholus range from 500 m [6] to 3.5 km. [11] Most of the volcano's surface is mantled with a thick layer of fine ...
