A copy of one of the sensors on NASA InSight's seismometer, compared to a 2-euro coin (about 1 inch wide). The short-period seismometer has three of these sensors.

JPL manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama.

France's national space agency, Centre National d'Études Spatiales (CNES), Paris, leads the consortium that provided SEIS. The principal investigator for SEIS is Philippe Lognonné of the Institute of Earth Physics of Paris (Institut de Physique du Globe de Paris, or IPGP). Imperial College, London, and Oxford University made the short-period sensors.
