studiot Posted August 12 Posted August 12 Reservoir of liquid water found deep in Martian rocks Image source, NASA Image caption, The discovery comes from analysis of data from Nasa's Insight lander, which took a seismometer to Mars Victoria Gill Quote https://www.bbc.co.uk/news/articles/czxl849j77ko
MigL Posted August 13 Posted August 13 There is water on Mars, but always assumed it would be only in frozen form, like at the poles. Liquid water at depths of 6-12 miles, means Mars' core provides significant heating, and possible habitable underground zones. And we don't need Doug Quaid to go start the huge nuclear reactor to melt the underground ice and provide an atmosphere and seas to make Mars habitable. If I 'totally recall' correctly ...
tylers100 Posted August 14 Posted August 14 Kinda interesting. Natural transition scenario: If build habitable underground zones then maybe inevitably Mars might will have a magnetic field if possible then can move toward habitable surface in future, see: "The seismic measurements from the InSight lander revealed that the Martian outer core is in a liquid state and larger than expected.[19] In one model, a partially crystallized Martian core explains the current state of Mars (i.e., lack of magnetic field despite liquid outer core), and this model predicts that the magnetic field has the potential to be reactivated in the future." from link: https://en.wikipedia.org/wiki/Magnetic_field_of_Mars#Dynamo_mechanisms
Airbrush Posted August 14 Posted August 14 (edited) Another point for life on Mars: Signs of liquid water discovered under the planet's surface (msn.com) "Scientists discovered evidence of a reservoir of liquid water seven to 13 miles below the Martian surface, lingering in the pores of the planet's crust. They believe there's enough to cover the entire planet with an ocean about one mile deep. The water, if it exists, is too deep to access in the foreseeable future. Still, it's another promising sign that Mars could one day yield the most disruptive discovery in human history — that of life beyond Earth." How difficult would it be to drill for that water "7 to 13 miles" below the Martian surface? How long will it be before we have the technology to drill that deep for water? Russia drilled the Kola Superdeep Borehole which is over 7 miles deep. Or will the water ice found at the poles be the main source of water for people on Mars for a very long time?

Not as hard as getting the drilling equipment there in the first place. 6 minutes ago, Airbrush said: Russia drilled the Kola Superdeep Borehole which is over 7 miles deep And it took 20 years for the drill to get that far. Thr bigger question IMO is what if any life exists in that water

That sounds very difficult. How does anyone restart the Mars dynamo? That sounds as difficult as terraforming Mars. In the Scifi movie "The Core" they restart Earth's dynamo using a series of nuclear explosions. Edited August 19 by Airbrush

I'm not sure, off top of my head is recharging Mars' core kind of like recharging a vehicle's dead battery but maybe that is a bit too simple and naive.. ?
