Seismometer to Go to Mars!

Just the other day, I was complaining about the fact that there are no seismometers currently on Mars.  Well, the good news is that NASA has decided to send a probe with a seismometer.  This is a real step in the right direction; it will be the first probe to punch significantly beneath the Martian surface (to a depth of about 5 meters).  Presumably, this means it will be able to drill through rock, since there is no guarantee that the InSight probe will land on a deep and stone-free patch of soil. 

This will be an important step; although the InSight probe will be concentrating on heat flow, at some point there will be a need to drill into an aquifer and take a sample of the water -- if there is any life on Mars, that might be the most likely place to find it.


My next wish for Mars is for a rover that will plant a grid of electrical probes and perform electrical resistance tomography to look for an aquifer and see if it is in motion.
