The Surprising Ways Mars is Hostile to Life

HOW TO FIX MARS TO LIVE ON : ( WITH EXISTING TECH 2019 )
Step 1: Using the tech created to generate a magnetic field for research ( upscale it )  outfit pre programmed nodes launched and landed in key spots = protection 1
Step 2: create node clusters equipped with pre programmed self drills with payloads  designed to ignite and re heat the core aimed at key spots for a chain reaction = Protection 2 
Step 3 : create seeding nodes landed at key points - consisting of algae & water with other vegetation seeds light enough to be spread via wind to thicken the atmosphere and produce O2 = Setting 1
Step 4 : Repeat seeding with genetically modded algae and more water to cement change with very little water present  = Setting 2 


using the planets natural cycles  as well as weather patterns if provided the proper protection via magnetic field repair the planet could be set to support life without a lot of effort.
