It’s a one-way ticket to Mars! So why can’t we go to Mars and return?

Mankind landed on the moon 50 years ago and could return from the moon. So, can humans safely return to Earth after landing on Mars? But scientists tell us that with our current technology, we are still unable to return to Earth from Mars. In other words, if we land humans on Mars now, it will only be a one-way ticket. The astronauts will stay on Mars and cannot return to Earth. . Why is this? Let's hear what scientists have to say.

Many people may not understand that a round trip can be achieved by landing on the moon, why not Mars? The moon's gravity is only one-sixth of the earth's, and the moon is very small. An aircraft can escape the moon's gravity and enter space with just a general boost. Moreover, the moon is close to the earth. After entering space from the moon, it can go to the International Space Station for supplies and supplies. Rest before returning to Earth.

Although Mars is not as massive as the Earth, its gravity is equivalent to one-third that of the Earth. To enter space from the surface of Mars requires a lot of thrust, and requires the use of rockets. It requires a boost to enter space, and Mars is relatively far from the earth.

After our spacecraft from the Earth to Mars lands on Mars, if the spacecraft wants to return to the Earth, it will need a lot of booster fuel. Some people may say that the fuel can be transported from the Earth. This method is also feasible. But the cost is too high. For example, launching a spacecraft into space from Earth requires 632 kilograms of fuel per kilogram of mass, while launching a spacecraft from Mars into space requires more than 10 times more fuel per kilogram of mass, which is unbearable for humans.

Therefore, scientists have proposed that the best way to land a spacecraft on Mars and return to Earth is to use local materials, mine them on Mars, and then convert them into materials and fuel needed for rockets. To achieve this, mining equipment and other related equipment need to be sent to Mars. However, these mining equipment and other equipment are very heavy. Although theoretically feasible, it is very difficult to implement them with current technology.

And the distance from the Earth to Mars is not short. The current spacecraft takes about half a year to travel from the Earth to Mars. During this period, maintaining the materials needed for the crew is also a serious problem. Supplies needed for the return trip are even more difficult.

Therefore, this is also the reason why humans have been exploring Mars for many years, but there is still no manned landing on Mars. It is relatively easy to achieve a one-way ticket for manned landing on Mars, but the return trip is not yet possible and requires more advanced technology.

The important reason that restricts humans from traveling to and from Mars is the engine. If humans can develop a spacecraft that can enter space without rocket boosting, it will be relatively easy to land on Mars and return to Earth. The spacecraft cannot enter space without the help of rockets. It is impossible to rely on current engines and fuel. We need more powerful fuel engines, such as nuclear power engines.

If humans fully master the controllable nuclear fusion technology and develop a real nuclear fusion engine, relying on its powerful power can completely escape the gravity of the earth and enter space, and the speed of the spacecraft sailing in the universe will also be With a significant improvement, it may only take about a month to travel from Earth to Mars. At this time, it may be that human civilization has truly entered interstellar civilization. It can freely explore the planets in the solar system, and it will be very easy to return to Earth from Mars.

In addition to mastering controllable nuclear fusion technology, there is also a more powerful technology that would be even more remarkable if it could be successfully researched. This technology is anti-gravity technology. Those UFOs that humans have witnessed can hover silently, freely, and at extremely fast speeds. These UFOs may use anti-gravity technology.

Anti-gravity technology can ignore the gravity of the planet. The spacecraft inside the planet is equivalent to being in the space environment. With anti-gravity technology, it can easily escape the gravity of the planet and enter space without a strong boost force. , and the speed of navigation in space will be faster, reaching sub-light speed or even light speed. This is an epoch-making technology and an important symbol of whether a civilization is truly powerful.

Anti-gravity technology can also achieve the same gravity environment as the earth inside the spacecraft. In this way, people's comfort will be greatly improved, and the safety of the spacecraft will also be greatly improved. At this time, the spacecraft can be considered a real The interstellar spacecraft, unlike the current spacecraft, is in a weightless state inside, making it inconvenient to do anything.

It is not easy to achieve breakthroughs in the above two technologies. I believe that with the continuous efforts of scientists, humans will be able to master controlled nuclear fusion technology and anti-gravity technology in the future. However, scientists plan to achieve manned landing on Mars and then return from Mars to Earth in the next 20 years, and it is estimated that they will still have to work hard on rocket fuel boosting.

Scientists plan to establish a base on Mars in the future and then transport some related equipment to Mars. Once there is a base on Mars, mining, smelting, and rocket manufacturing can be done on Mars. In this way, after the spacecraft lands on Mars, these rockets can be used when returning to Earth. It is believed that Mars will become mankind's second home in the future, and friends may have the opportunity to travel to Mars or immigrate to Mars.
