InSight and Perseverance have sent back unprecedented data on everything from marsquakes to the Red Planet’s inner layers.
...
This week, scientists are dropping an Olympus Mons of findings from the two brave robots. In three papers published today in the journal Science—each authored by dozens of scientists from around the world—researchers detail the clever ways they used InSight’s seismometer to peer deep into the Red Planet, giving them an unprecedented understanding of its crust, mantle, and core. It’s the first time scientists have mapped the interior of a planet other than Earth. And yesterday, another group of scientists held a press conference to announce early research results from Perseverance, and the next steps the rover will take to explore the surface of Jezero Crater, once a lake that could have been home to ancient microbial life.

A closer reflection on the presented facts about the nature of the Mars land possibly gives a good image of how it may be unable to support agricultural production. So maybe hydroponic and aeroponics for food?

This sounds right.
I think the absence of surface water is a big issue, but I learned in this article that Mars lost its magnetic field, which resulted in a lack of atmosphere, so the planet is also not protected from solar radiation. Add that to temperature fluctuation that hinders life, and you have a tough situation. Engineers will need to be extremely innovative to support life on Mars; I suppose pioneers we'll have to manufacture just about every aspect of an agricultural environment.

Exactly! Good point on the Sun's radiation.
