  1. Today, Mars is believed to be largely tectonically inactive. However, observational evidence and its interpretation suggests that this was not the case further back in Mars's geological history. At the scale of the whole planet, two large scale physiographic features are apparent on the surface. The first is that the northern hemisphere of the ...

  2. Feb 24, 2020 · Mars may be cold and dry, but it's far from dead. The first official science results from NASA's quake-hunting InSight Mars lander just came out, and they reveal a regularly roiled world. "We've ...

  3. Mar 23, 2021 · Mars, however, is mostly tectonically inactive, and so the “drying” of the surface, once it occurs, is permanent. “Atmospheric escape clearly had a role in water loss, but findings from the last decade of Mars missions have pointed to the fact that there was this huge reservoir of ancient hydrated minerals whose formation certainly decreased water availability over time,” says Ehlmann.

  4. Mar 31, 2021 · Jezero Crater on Mars is the landing site for NASA’s Mars 2020 rover. Image Credit: NASA/JPL-Caltech/ASU. ... But since Mars is tectonically inactive (for the most part), its surface water was ...

  5. Mar 19, 2020 · NASA’s InSight mission is the first lander to deploy a seismometer on a planetary body since more than 40 years. With a year of seismic data from Mars, new discoveries on Mars’ tectonics and ...

  6. Oct 11, 2024 · The problem is a difficult one because blowing dust on Mars can obscure small craters, but Mars Global Surveyor (MGS) images, obtained in the past few years for some areas by the Mars Orbital Camera (MOC), show neither significant mantles of dust nor many craters, which leads Hartmann to believe that the flows are very young. He argues that this work is essentially confirmed by dating of ...

  8. Oct 30, 2018 · This has been a long-standing question in planetary science. From the Martian meteorite basalts (shergottites), we know that martian volcanoes have erupted within the past approximate 180 million years, which is very recent in terms of solar system geology. Elsewhere in the solar system, proof of active volcanism comes from images of erupting ...
