What conditions do humans need to fly to Mars?

Manned landing on Mars requires four basic conditions:

1. Design bigger spaceships and rockets.

Mars is 0.55 ~ 400 million kilometers away from the earth, which is about 150 times the distance between the earth and the moon. At the current speed of human spacecraft, it will take about six months to reach Mars. Since there is no transit station for supplies between the Earth and Mars, it is necessary to bring enough fuel and astronauts' living materials at one time when starting from the Earth.

2. Spacecraft landing technology.

The current landing mode of the probe is not suitable for manned spacecraft. A large rocket with enough materials and fuel must have high requirements for landing on Mars, because it involves the fuel on the spacecraft, necessary instruments, materials and the safety of astronauts. Need to master more advanced deceleration landing technology.

3. Solve the problem of cosmic radiation.

The earth has a dense atmosphere and a strong magnetic field, which protects the creatures on the earth from the sun and even cosmic rays. Due to the lack of magnetic field and atmospheric protection, Mars is equivalent to direct exposure to terrible cosmic radiation. If there is no very good protective measures, it will directly threaten life.

4. Have the ability to build shelters after landing on Mars.

The purpose of landing on Mars is to establish a base where humans can stay and explore Mars for a long time, which will involve the construction of shelters. If we rely entirely on the earth to transport building materials to Mars, it is not only costly, but also time-consuming. Therefore, it is necessary for human beings to master a technology that can use local materials and build bases quickly.

Mars landing plan of "Mars I" research institute in the Netherlands;

1, the agency's "Mars No.1" 20 14 1.2 announced that 1058 people were selected from 200,000 applicants to participate in the second phase of training for emigrating to Mars. 1058 people will be eliminated many times, and finally 24 "strong men of the earth" will be screened out and will go to Mars in 6 batches in 2024.

It is worth mentioning that there is no return ticket for this trip to Mars, which can be said to be "there is no return". In other words, these 24 "strong men of the earth" will become permanent immigrants who will die of old age on Mars, because they all use "one-way tickets".
