![Vertical component spectrogram of event S1094b, caused by a meteoritic impact (Posiolova et al., 2022). The bottom two panels show P- and S-wave spectra in several 60 second time windows following the direct arrival. The spectral shape stays consistent throughout the inital 150 and 230 seconds after arrival of the phase, indicating an equipartitioning of seismic energy with no significant viscoelastic attenuation. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Discrimination-of.png?resize=1200%2C719&ssl=1)
[astro-ph.IM] The NASA InSight mission observed over 2000 marsquakes in the course of its three year mission. These quakes varied in magnitude between 1.5 and 4.5, as well as in […]

The Presence Of Liquid Water Is The Most Probable Explanation For Data Collected By Mars Insight
Data about Mars’ planetary crust gathered from the Mars InSight lander are best explained by the conclusion that the crust has stores of liquid water. Analysis led by Vashan Wright, […]

There Are Oceans Of Water On Mars. They’re Just Too Deep To Tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet’s surface.
