Philae’s SESAME-CASSE ‘listened’ to the #lander’s MUPUS instrument hammer the surface of Comet 67P/Churyumov-Gerasimenko last November. Martin Knapmeyer from the German Aerospace Centre, DLR, tells us more. SESAME-CASSE is the Cometary Acoustic Surface Sounding Experiment located in the lander’s feet. It takes the form of three accelerometers, each of which records acceleration in three directions (one vertical and two horizontal). MUPUS comprises the Multi-Purpose Sensors for Surface and Subsurface #science – including the MUPUS penetrator that was activated towards the end of #philae’s first science sequence on 14 November 2014. It was recognized early in the preparation of both experiments that the hammering mechanism of MUPUS, which drives a thermal probe into the comet’s surface, would (...)
