@paulfree14 Which part, having a seismometer, or having three seismometers? :D

@paulfree14 Ask anything you want, I love teaching.

@icefox
the part about having it on the #mars. :-p

@paulfree14 We have almost no actual information about Mars's interior... basically just what we can observe from Earth and infer from what we see on the surface. Having seismic information from Mars can tell us things like how thick its crust is, whether its mantle is solid or still hot enough to be kinda-squishy like Earth's, how large and solid its core is, stuff like that.

@paulfree14 Besides Pure Science, and using it to understand more about Earth and the universe, the most likely place to find life on Mars is probably hot spring type environments, like Earth's hot springs. To produce these you need volcanic activity. We know Mars has lots of volcanoes, and some of them LOOK like they've been active SORTA recently, but knowing more about Mars's innards might give us a much better idea of how likely hydrothermal systems are, and where to find them.

@paulfree14 Also. Marsquakes. MAAAAARSQUAKES!
