[End of Crisis Era 4, Mars]

NASA's first delivery spacecraft have already arrived on Mars, and they will use science and technology to transform Mars into a habitable planet. Mars is the most likely to survive in the solar system, and it only takes a little change in the parameters of Mars to make Mars viable. But as long as one of the parameters is changed, it is very expensive, and in order to survive, this risk has to be taken.

The first fusion spacecraft have reached the orbit of Mars, and the spacecraft will be launched just when Mars is closest to Earth. If it weren't for the federal government's sanctions on Starry Sky a few years ago, Starry Sky would have built a large number of fusion spacecraft, and it might have been possible to use Starry Sky's fusion spacecraft and land on Mars early. It has been calculated that if the federal government had not taken measures against the "starry sky", the possible landing on Mars would have been completed in 3 years of the crisis. Yes, the world is unpredictable.

People have seen Mars, for the hundreds, thousands, but only a few times. Mars as a whole was fiery red, like a burning ball of flame, like a candle in a temple. The overall look is relatively complete and smooth. But when the ship descended to a thousand meters, the outlines of some craters appeared, like weather-beaten red warriors. The meaning of Mars in mythology is also the god of war, and it also has a name "Mars", which is derived from "Ma."

The word "s" is transliterated. In mythology, each planet symbolizes a god. Mars is the most similar one, red - originally divine. In the future, people will live in the body of the "God of War".

After a while, they landed on Mars, stepping on hard red sand and gravel ground. They are not surprising, because the future will always be on this path.

"Oh my God! How did the sun turn blue? Said one of the youngest women in the formation. The pair of astronauts who landed on Mars are known as the "Forerunners", and they were the first of the human settlers to arrive on Mars. This huge formation carries a lot of engineers and designers. Now the technology to deal with the space environment has become better, so anyone who has a spaceship and knows how to do it can go to space. Nor does it need to be trained as rigorously as it did at the end of the Common Era a century ago.

Everyone looked in the direction the girl said, and the sun was many times smaller than it was seen on Earth, and it was blue at the same time. The reason is that the Martian atmosphere is very thin, the atmospheric molecules have almost no scattering behavior, and Mars often blows sandstorms, so there is a lot of dust in the air, and they will scatter light of about the same wavelength as their own size, and the size match is found to be red light with a longer wavelength. So, the red light of the sun's rays on Mars is scattered, and the blue light can penetrate in. So the Sun is blue relative to people on Mars. The principle is known as a type of scattering: Mir scattering.

Against the backdrop of the blue sunset, the "forerunners" began to work. The frame of the house is particularly spectacular against the backdrop of a red sky.

The most beautiful thing is the sunset...... Blue?
