Humanity plans to use the "Redwood Forest" to establish a Mars colony. What about the terraforming of Mars in 600 years?

In the long run, it will be impossible for people to live on a planet. We don’t know when, but one day, there will be more humans living on alien planets than on Earth. ?

Human probes have reached all planets and large satellites in the solar system. After comprehensive consideration, Mars is considered an ideal planet for human colonization.

Currently, it is not a huge problem for human spacecraft to take astronauts to Mars.

The biggest problem is how to survive and establish colonies on Mars for a long time.

The surface of Mars is a barren land. The boundless Gobi Desert covers the entire planet, and dust storms more powerful than Hurricane Katrina blow from time to time.

Mars has no liquid water, and the toxic air contains high concentrations of carbon dioxide, making it difficult to breathe; the average temperature is minus 63 degrees. , will freeze people to death.

Mars offers nothing directly capable of sustaining life.

This means that the first batch of astronauts must bring all the supplies needed to survive for 18 months.

In order to colonize Mars, a research team from the Massachusetts Institute of Technology designed the "Redwood Forest", an open public dome forest ecosystem.

A doctor from MIT is leading an interdisciplinary research team and has completed the design of a "Redwood Forest" model, which is being built in a desert environment similar to Mars. Conduct ecological experiments. Sequoia Forest's opalescent dome structures will conceal a series of underground tunnels that will connect each dome structure together and protect residents from meteorite impacts, space radiation, and extreme changes in temperature.

Each redwood forest has a small nuclear device that generates electricity; outdoor protection, work and transportation are coated with super anti-corrosion paint; and there are plants that survive in zero gravity, their Its function is to provide food and convert the carbon dioxide exhaled by the astronauts into oxygen. Tried in Earth's deserts, the most efficient plant, both in terms of providing food and recirculating oxygen, turned out to be dwarf wheat. ?; Water circulation system, etc.

The colony, which is composed of redwood forest balls, can accommodate more than 10,000 people in the first phase.

After the first phase of the colony is established, humans will consider using the large amount of resources existing on the surface of Mars, such as: water ice, carbon dioxide and dry ice, which can be used as drinking water, oxidants and fuels. This is not Unrealistic fantasy. ?

Use these resources for later construction.

So far, most of the technologies for establishing a Mars colony have been formed. The biggest problem is the extremely expensive cost.

If the cost can be significantly reduced in the next 50 years, mankind will Colonize Mars and complete the plan to immigrate 1 million people to Mars within 50 to 100 years.
