The article discusses using a 5 kilowatt laser to drill down through the
ice of Europa to the subsurface ocean. This may also work to drill
beneath the ice at the Martian south pole for the recently discovered
liquid water lake.

For the Europa case, they needed nuclear power for the 5 kW laser. But
solar power might work for Mars.

It would be wiser to scrap the sub and analyze the red brown and other
coloring that oozes from the cracks below.

The Galileo probe showed dark material around the cracks of the ice.

It would be much easier to analyze that material first. Of course that
would justify building later a more advanced explorer, but just a
surface machine (a rover) that would analyze the cracks in the ice would
surely yield very interesting results.

We have arrived at one of the biggest oceans in the solar system. No
need to drill first.
