“For example, there are small traces of hydrogen ... “We’ve made the very first observations of seismic waves travelling through the core of Mars. Two seismic signals, one from a very ...

The probe landed on Mars in the fall of 2018. It was equipped with a seismometer that recorded the seismic waves from two meteorite impacts in 2021 and a marsquake in 2022. While investigating a ...

Seismic waves travel at different speeds through Earth depending on the rigidity of the rock they're passing through. For example, a type of seismic wave called a P-wave travels more slowly if the ...
