Résumé:

<p>We review briefly from the instrument and mission perspective the development of planetary seismometry. A first section describes the basic measurement principles of seismometers, as well as their limitations. This section includes also a description of the challenges due to technological constraints of space qualification. We then present and compare the different seismometers implemented on past missions, namely the series of lunar missions culminating in the Apollo seismic investigations and the past attempts to investigate the seismology of Mars. We review the current terrestrial seismic instrumentation and how techniques have been developed to isolate the seismic signal from all other sources.&nbsp; Finally we look forward to the future, nearer term with the seismic instrumentation on the InSight mission to Mars, and beyond to other seismic investigations throughout the solar system.</p>
