a lot about the surface of mars we know a lot about its atmosphere and even about its so i honestly are but we don't know very much about what goes on a mile below the surface much less two thousand miles below the surface down to the center this heat probe should be able to fill in some of those gaps developed by scientists at the german aerospace center it will measure the temperature of individual underground layers and determine how efficiently these layers conducts heat to do this the probe will have to burrow deeper into mars surface than any previous drill. another instrument will monitor how much mars north pole wobbles as it orbits the sun. and for the first time a seismometer will measure seismic five gratian on mars surface caused by earthquakes and meteor strikes the data acquired by all three experiments will make it possible to make new suppositions about the inner structure of mars and the
