Why has knowon ever landed on mars?

Answer 1

Well the travel is the main reason because 6 months in space won't do good because of 0 gravity will affect your bones making them weak. Reason 2 mars orbits the Sun slower and the only time we could go is in the next 2 years when the earth and mars are a there closest. Reason 3 sevarel probes have crashed from a minor fualt or engines not kicking in from the cold. Reason 4 oxygen and resources we could run out of oxygen and die or resources no food equals starvation. My theory on how to get there: if you could get enough resources after passing the atmosphere use rockets to make the shuttle spin there by making artificial gravity reason 1 solved. Now fyi mars has gravity 1 third of the earth now slowing the process of the weak bones problem Reason 2 partially solved. By creating heat on the engine several days from landing won't crash the shuttle and the technology fualt were back in the 80s and 90s Reason 3 solved. If theres enough resources for six months perfect all needed now is plant seeds like fruits for this to work now is a green room. Plants produce oxygen so that solves oxygen and for the plants to live is water, for that you need to land near the ice caps. All reasons completed.
