Human exploration of space has been going on for decades, and as long as it is the exploration of outer space, it is all an impact on mankind.
The first landing on the moon, the launch of the space shuttle, the crossing of astronauts and the construction of the International Space Station, etc., all make people sigh at these human feats.
There is a kind of exploration, even if you don't know the outcome, you are willing to explore, and this is human curiosity.
This curiosity is also the driving force behind human progress.
At present, human exploration of Mars has also made progress, but is it capable of going to Mars?
What kind of difficulties do you face, even if you do?
1. Distance and time
Mars is also an important target for human exploration, but Mars is still quite far from our earth.
The average distance between Mars and Earth is about 200 million kilometers, and when it was closest to us, it was 560 million kilometers.
The distance from Earth to Mars is about 7 months.
From this distance, it can be seen that if humans want to land on Mars, it will take at least 579 days to reach Mars.
So what difficulties will humanity encounter during this 579-day voyage?
First of all, when leaving the earth, the rocket will be ignited 3 times, and after the first ignition, the rocket will enter the state of orbital operation, which can be maintained for more than 200 days, but the current payload of the rocket cannot meet the standards of the astronaut's entry into orbit, so it is also necessary to do a rocket ignition to send this vehicle near the earth's overflight point.
And when the rocket reaches the Earth's overflight point, it also needs a third rocket ignition to send the vehicle into orbit on Mars.
In this way, the operation needs of the vehicle from Earth to Mars can be realized.
It can be seen that the number of ignition of the rocket alone is 3 times, and the time of each ignition cannot be too long or too short, and the energy and orbit of the vehicle need to be guaranteed.
If all of this goes smoothly, it means that the astronauts have successfully entered orbit and are getting closer and closer to landing on Mars.
Next, humanity faces a huge challenge – astronauts will live in space for almost a year before arriving on Mars.
This year is not only a challenge to the astronauts' bodies, but also to their psyche.
During this year's voyage, astronauts not only have to live in a limited space, but also have to adapt to the state of gravity, and also have to adapt to the strange environment in the universe, which is a great test for the physical and mental health of astronauts.
There is still some work that must be done to ensure that astronauts can safely reach Mars during this year's time.
First of all, before landing on Mars, astronauts must make strict measurements of the environment on Mars to ensure that the environment on Mars is safe for human survival.
Secondly, astronauts need to carefully understand and train the entire process of landing on Mars.
If an astronaut has an accident while training, they will face uncontrollable consequences when they officially land on Mars.
There are too many reasons that will put astronauts at risk to their lives, so when training, it is necessary to strictly control the actions of astronauts to reduce accidental casualties of astronauts during training.
In this way, you can be guaranteed to explore Mars for a longer time and understand the environment and conditions on Mars in more detail.
For astronauts, this year, they will live in the universe, living in a gravity-free environment, which is a great challenge to human body and psychology, so astronauts must have enough psychological tolerance and adaptability to cope with various strange environments in the universe.
2. The challenge of landing on Mars.
After the astronauts arrive on Mars, they will face a huge challenge – the Martian atmosphere.
Mars has a dense atmosphere, which is a great threat to astronauts.
Because the astronauts' vehicles are designed on Earth, where the atmosphere is thin, while the atmosphere of Mars is dense, when the vehicle descends, it will be subject to the inertia and pressure caused by high-speed flight, so it will not be able to land accurately.
In order to ensure the safety of the vehicle's landing, the vehicle will use the density of the Martian atmosphere to slow down to reduce the vehicle's descent speed and achieve a safe landing.
During the descent, the vehicle undergoes a series of deceleration movements to reduce the descent speed of the vehicle and ensure that the vehicle can land on a predetermined trajectory.
The climate conditions on Mars are also very harsh, the temperature can reach 25 degrees during the day, and the temperature will drop below zero at night, such a temperature change will cause great physical and psychological damage to the astronauts.
In addition, the air pressure on Mars is also very low, only 0.006 of the Earth, and the air pressure of the Earth is 100 times that of Mars, which will cause great damage to the astronauts' bodies.
In order to ensure that astronauts can survive safely on Mars, a complete life support system must be established for astronauts.
One year on Mars is equal to two years on Earth, so as soon as astronauts arrive on Mars, they will have to upgrade their life support systems to adapt to the harsh environment on Mars.
Before arriving on Mars, astronauts must also make strict measurements of the environment and climate on Mars to ensure that the environment on Mars is safe for human survival.
In addition, the gravity on Mars is only 1/3 of that of Earth, so humans will walk faster on Mars, which puts forward higher requirements for the accuracy and speed of astronauts.
Landing on Mars is a major breakthrough for human beings, but the environment on Mars and so on will put forward higher requirements for human survival, but human landing on Mars is also of great significance.
First of all, the landing of humans on Mars is of great significance for scientific research.
After landing on Mars, humans can understand the environment on Mars in more detail, which is more valuable information for scientists, and scientists can judge the development of Mars through this information.
At the same time, scientists can also look for signs of life in the soil on Mars, which is of great significance for the search for extraterrestrial life.
Secondly, the landing of humans on Mars can also prepare for future exploration and potential.
Scientists have discovered that there is a sea on Mars, so there may also be water on Mars, and water is also the source of life, so there may also be life on Mars.
In addition, scientists have also discovered that the soil on Mars contains minerals that can also provide resources for humans, so this may also be the potential for human exploration of the future.
III. Conclusion
For human beings, Mars is not only a land unknown to human beings, but also a forbidden land for science, but there are still too many unknowns and challenges for human beings to land on Mars.
There are still too many technical problems to overcome for humans to land on Mars, so human landings on Mars still need to be continuously researched and tested to make all preparations for human landings on Mars.
