This question already has an answer here:
Could Mars's magnetic field be restarted by its own moon? I've done some research (and I am definitely no scientist) but I am looking for answers. I know that Mars has two moons, one of which is on a orbit that could end in it hitting the red planet. Could this lead to the restarting of Mars's magnetic field, blocking deadly solar radiation, allowing liquid water to form and stay, and creating weather--and ultimately, a habitable planet apart from Earth on which we could start our first ever colony?
