Watch InSight's successful landing on Mars: Difference between revisions

 

They expect also to detect impacts of Martian meteorites; one of their objectives will be to get a better idea of the impact rate. The seismometers will be able to detect even the one cm or so rise and fall of the surface due to passage over of Phobos the innermost tiny moon of Mars which will also help them make discoveries about the Mars interior. They can also detect the orientation of Mars - the RISE (Rotation and Interior Structure Experiment) experiment can detect the slight wobble of the north pole as the gravity of the sun tugs at it during Mars's elliptical orbit which will help decide if Mars has a liquid core and how large it is.
