What are you looking for on Mars?
Age 4.5 billion years
Distance from Earth - between 50 and 250 million km, depending on the relative position of the two planets and the Sun.
Climate - The last rainstorm happened a billion years ago, but beware of dust storms.
Daylight - the only planet whose day length is close to that of Earth (more precisely 24.5 hours).
Atmosphere - extremely thin, its density near the ground is only one percent of that of the Earth, and it does not allow flowing water, but it is especially good for producing fuel for the return trip from the atmosphere of carbon dioxide.
Getting there - it takes 6 months to get there by spacecraft (like an average stay on Mir). Landing may be delayed due to local sandstorms.
Getting around - there is no public transportation there, a gravity of 40 percent makes it easier to walk, but usually you should take an SUV.
To return home - separate the carbon dioxide from the atmosphere and mix it with a little oxygen to produce methane and water, remove the oxygen from the water. Repeat the process until you have enough methane and oxygen to fill the fuel tank. About 30 tons.
what to see
Olympus Mons, the highest volcano in the solar system - 27 km high (3 times the height of Everest). It has not been active for at least a billion years. Wallis Marineris - a fissure that makes the grand canyon in Colorado look like a canal. The width of the canyon is like that of North America , and its depth is seven kilometers.
Mangala Valley - a dry river channel, with a network of sub-channels, similar to the Amazon River Delta,
So much so that its lower part is called Amazonis Plantia. A good place to dig for underground water and evidence of past life.
