In the middle of the night of September 28, Beijing time, NASA (NASA) held a press conference to announce a brain-opening blockbuster news - the first time on Mars found "strong" evidence of the existence of liquid water! As soon as the news was announced, there were immediate comments that the discovery of water made the existence of microorganisms possible, and there was life on Mars, so these signs of life may be maintained until now. Is it possible that the head-long antenna and ear-modulated comic "Uncle Martin" who left a good memory of the childhood of a large wave of post-70s and post-80s can really exist?

"Uncle Martin of Mars" is a huge funny American drama, with 107 episodes, broadcast on CBS from 1963 to 1966, about martin the Martian martin due to the failure of the spaceship, had to stay on the earth temporarily, met the reporter Tim, the two had a love experience. Although Martin has become a human form, as a Martian, he has a retractable antenna behind his head, can be invisible, can see through other people's minds, can move things through the air, loves ice cream, and is super kind... Not having seen it is definitely a loss of life.
Speaking of this discovery, it is mainly NASA's Mars Reconnaissance Orbiter (MRO) that took a strange picture of the surface of Mars as early as 2010, and this stripe becomes thicker and longer in the warm season and fades and shrinks in the cold. Later, the visible infrared spectrometer on board the MRO determined the mineral composition in the black stripes by observing different wavelengths of light, and Alfred McEwen, a professor of planetary geology at the University of Arizona and the research leader of NASA's high-resolution imaging science equipment for nasa's Mars project, and several other scientists discovered that there was something called perchlorate.

The pictures show a significant frost phenomenon on the surface of Mars.
McCaevian said this is direct evidence that water exists in the form of hydrated salts, and it is likely that liquid water has recently existed on Mars to produce hydrated salts. The "nearest" time can be measured in days. According to this, Jim Green, head of NASA's planetary exploration department, said at the press conference: "NASA confirms that in some specific cases, liquid water exists on the surface of Mars. ”
The paper on this discovery has been published in the journal Nature Geoscience, and the students are self-reliant, and the slag only needs to know, and there is a bunch of instructions from BLABLA above: there is liquid water on Mars, and it is a kind of salt water.
Although it is salt water, it is already very good for earthlings, after all, 70% of the earth's surface area is oceans, which is also salt water! As long as there is salt water, fresh water can be separated. Moreover, water can produce oxygen and hydrogen after ionization, and as for electricity, solar energy! Therefore, in theory, as long as there is water on Mars and the use of existing human science and technology, the basic living conditions are available.
In 2003, the Hubble Space Telescope took a photo of Mars reaching the closest point to Earth within 60,000 years! Like not like a big egg yolk?
Mars is much smaller than Earth and has a surface area as large as Earth's land area. In 1996, two of the 9 reasons given by the famous astronomer Carl Sagan to explore Mars were particularly fascinating: Mars is one of the closest planets on Earth that humans can explore; mars may be a planet for people to move in the long run.
Looking at the distribution of planets in the solar system, Mars is next to Earth.
However, this "closer" is in the astronomical category, Mars also revolves around the sun like the earth, although the time of a day on Mars is roughly the same as on Earth, but its orbit is a flat oval, so one year on Mars is equivalent to two years on Earth. I won't tell you that because of this elliptical orbit, Mars is about 55 million kilometers away from Earth at its closest point and more than 400 million kilometers at its farthest! If you go to Mars in an ideal state and take the fastest spaceship on Earth, the shortest time is 39 days, and the longest is 289 days. Well, that's right, it's almost a year to fly!
Even if it takes a year to fly, the energy crisis, the population explosion... A bunch of unsolvable problems also forced the battle bullies on Earth to set their sights on Mars, which was next to Earth. Especially before 2012, the famous "Nostradamus 2012 Doomsday Prophecy" was rumored to be a god, and the American blockbuster "2012" was mixed with a foot, "Do you have a ferry ticket?" "It was a hot topic for a while.
What's more exaggerated is that some people have searched Google satellite maps and said that, as described in the movie, the "Noah's Ark" that responded to the end of 2012 was really built in Nyingchi, Tibet, China, and the location is also very certainly said to be near Nyingchi Airport. The reason is very simple, because China's Tibet is the "roof of the world"! Of course, it is safer to stay in a high place at the end of the world! And it's obviously easier to get on board the airport by a private jet when the global elite with a ticket is close to the airport. But why not just build it at the foot of Nagqu or Shigatse, the highest average altitude? Nyingchi is the lowest average altitude area in the Tibet Autonomous Region, okay... I don't read much, don't lie to me... Of course, in the end it turned out to be a prank...

At that time, the "end of the world" has been played badly by netizens... The construction site of "Noah's Ark" was marked by netizens on Google Maps to Nyingchi, Tibet, China...
Although the "end of the world" is fake, the United States has really begun to explore Mars non-stop since the 1960s. The United States plans to land humans on Mars around 2030. To that end, two astronauts on the International Space Station are conducting a 342-day "one-year mission" experiment to explore the possibility of long-distance human space travel. At the same time, other astronauts there have also grown vegetables in space to study how humans can be self-sufficient in food on their journey to Mars. In addition, Earth is also simulating Martian colonization. In August, six scientists entered a "living capsule" at the foothills of Mount Mauna Loa in Hawaii, where they would live in a "retreat" for a year and experience life on secluded Mars.

In addition to the United States, there are also Japan, the United Arab Emirates, India, Canada... A large wave of countries are gearing up to colonize Mars. What about China? If Mars is particularly good, aren't we lagging behind? Don't worry, China's "father of Chang'e" Ouyang Ziyuan revealed that China plans to achieve a landing patrol of the rover in 2020 and a sample return of Mars in 2030. Moreover, just in August this year, the Southern Research Institute of Space Science and Technology launched the "Green Airline Interstellar "Space Survival" Challenge 180 Days" experiment, which will explore new technologies and new methods for building artificial ecosystems in a closed environment, explain the characteristics of human physiology, psychology and behavior in a long-term confined environment, and provide technical reserves for carrying out manned space exploration, using space and expanding human living space outside the earth.
"The world is so big, I want to see it" seems to have been OUT, and now it is obviously the rhythm of "the universe is so big, I want to see it". Although this process is still very long, there are also many unpredictable dangers, you can make up for "Alien", "Galactic Team", "Star Trek" on your own... But you missed out on low-priced rooms, right? Missed the A-share bull market, right? Isn't it always said that "The earth is too dangerous, I still have to go back to Mars", if humans really start to colonize Mars in 15 years, will you still miss it? Now the house price is so expensive, why don't we go to Mars in a group? (China Tibet Network Text/Liu Li)
