That is actually why mars cannot harbor life now.

Back when Mars had a moon, the tidal forces made the core far more molten, which resulted in the stronger magnetic field (what keeps us all from roasting and our atmosphere from blowing away).

Once the moon was gone, the planet cooled, the magnetic field faded, and its atmosphere essentially blew away.

Some stats that could tragically be ruined:

I'm assuming they can't. Probably because the soil and climate just isn't right.

It really hasn't been serious till just this year and the one before. Luckily it should be the year of El Nino for Cali, that means a lot of rain!!

Those stats .

Cali almonds >>>> though. Although the ones from my native country are SO good.

I'll do some voodoo to make sure you guys get rain

Based on rock samples from craters they estimate the Martian magnetic field shut down early in it's life. These rocks were ejected from large impacts and contain no magnetism at all. There was no large moon to create the tidal forces to keep the core molten, if there was where is it? Mars' current moons are among the smallest in the solar system.

As big as our moon is it is only escaping Earths grasp at about 1.5 inches per year. By the time it is free from earth the sun will be a red giant so it won't matter. So again where is this moon mars had?

To create a strong field on a rocky planet you need convection around a solid iron core like we have or at the least convection for a weaker field. Mars probably had convection in it's early days but then for whatever reason the crust became locked, no plate tectonics and all the volcanic activity ceased. Probably because it's just to small of a planet. The core is still liquid though.
