Mars Express And Psyche Same Day Imagery of Mars
[ESA] On 15 May, whilst en route to a metallic asteroid, NASA’s Psyche mission flew just 4500 km above the surface of Mars. It was using the gravity of the […]
![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)
