How far do you think humans are from Mars?

In the foreseeable future, Mars will have an atmosphere, which is very thin. The atmosphere can also play a protective role, protecting us from all kinds of high-energy particles from outer space. The most important thing is that its day is almost the same as that on our earth. A day on Mars is about 24 hours, 20 or 30 minutes more. So living on Mars, the rhythm of day and night will not change much. A year on Mars is much longer than that on Earth. A year on Mars is almost two years on Earth, but it doesn't matter, because we want to live on Mars for a long time and grow crops. This crop must grow in a greenhouse and will not be affected by the seasons on Mars.
