Jul 14, 2014 · A new global geologic map of Mars –the most thorough representation of the "Red Planet's" surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration. The new map brings together observations and scientific ...

The evidence for a still-geologically active Mars comes from NASA’s InSight lander. InSight has been recording the faint seismic pings from marsquakes, the Martian equivalent of earthquakes. So far, InSight has detected over 1,300 such marsquakes. The researchers found that the epicenters of many of the quakes were in a region called Cerberus Fossa...
The nature of the low-frequency quakes suggests that there is still hot magma below the surface. The data from the marsquakes point to a warm source below ground in Cerberus Fossae. Could it really be lava? The researchers say that the epicenters of the marsquakes are clustered close to a “young volcanic fissure.” The paper states: How do scientist...
The new results are exciting, as they seem to indicate that Mars isn’t quite as dead – at least geologically – as previously thought. The red planet’s volcanoes may not erupt anymore, but even magma deep underground is a tantalizing finding. Such pockets of still-hot magma may be the last remaining embers of a much more active volcanic past on Mars...
Dec 5, 2022 · An ~4,000-km-diameter and 200–500-km-thick active mantle plume is present below Elysium Planitia on Mars, indicating that the Martian interior is geodynamically active and drives the volcanic ...
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 ...

Oct 11, 2024 · But while it loomed huge, it was apparently extinct. After examining these images, most scientists concluded that geologic activity on Mars had ceased long ago. More recent research on the planet, however, has convinced some scientists that Mars may still be geologically active.

Oct 19, 2016 · But the map also reflects new research that suggests the planet has been geologically active until the present day, with evidence for water erosion, glacial activity, and even so-called Marsquakes.
