  The NASA InSight mission has helped to measure the deep interior of Mars
using observations of seismic waves excited by marsquakes. Currently,
installation of seismometers on the moon is foreseen. We review the case for
seismic experiments on all major planetary bodies of the solar system. We
discuss scientific goals in accordance with the Decadal survey for planetary
science and astrobiology and the ESA Voyage 2050 program as well as technical
challenges and potential mission concepts, to answer the question: Where could
we do seismology on other planets and why should we do it?
