After saying goodbye to Frank, Hara went straight to his office

"Hao Chen, aren't you going to Super Lab No. 1 today?" Old Goethe saw Yuan Haochen who pushed the door in, and asked suspiciously.

"I won't be going for the next few days, you help me tell Amanda that I will stay in the laboratory for the past two days to collect information."

"Okay, I'm here to help."

"Thanks, Goethe." Then, Yuan Haochen seemed to remember something, and continued, "The archive center should still have some old graphic materials for Mars exploration decades ago, which may not be retained in the computer system, you can help me apply to bring them back by the way." ”

Looking at the departing figure of old Goethe, Yuan Haochen shook his head.

For the next research work of the meteorite, Yuan Haochen does not want to work with Amanda and them for the time being.

In order to avoid embarrassment, he asked Goethe Sr. to act as an intermediary to euphemistically express his attitude.

Yuan Haochen felt that there was a contradiction between his research ideas and those of Amanda and others, and Amanda's idea was to dig deep into the meteorite, hoping to find out more information about ancient life.

But Yuan Haochen felt that he should stretch out his hands longer, walk faster, and go to Mars to find the impact site of the space meteorite.

A strong instinct told him that more amazing images were waiting on Mars for earthlings to discover.

Therefore, it was only when talking to Frank that he decisively expressed his opinion, so as to gain Frank's support for him

Earth's interstellar exploration of Mars dates back as far as a century.

The formation and evolution of Mars are somewhat comparable to that of Earth, and scientists speculate that Mars once had conditions suitable for life, so exploring Mars can help us learn more about Earth's history.

According to the IEA (Interstellar Exploration Alliance) data, so far, the Earth has launched a total of 36 probes to Mars.

Among them, the successful landing on the surface of Mars includes: Challenger 1-3, Da Adventure 1-3, Canglong 1-2, Hope, Exclamation Point, Curiosity, Opportunity, Phoenix and other probes.

Of course, the IEA organization has also launched many Mars probes, but because of the extremely confidential nature of the IEA organization, these Mars probes were launched in the name of the International Astronomical Union.

Excluding the IEA, the country that has launched the largest number of Mars rovers is the United States. It is worth mentioning that China has also successfully launched the Canglong 1 and 2 Mars probes in the past decade.

In addition, in the outer space of Mars, there are dozens of artificial satellites in Mars reconnaissance orbit that are constantly scanning and observing more than 95% of the area of the Red Planet.

The information collected by the Mars reconnaissance orbit satellites has helped mankind to understand Mars, and scientists have used it to observe and speculate about some of the major changes that have occurred on Mars over the past hundreds of millions of years.

To this day, we can still see craters, avalanches, dust storms, seasonal and dry ice, salt water infiltration in the summer, and other phenomena on Mars.

In the plan to land on Mars, only NASA in the United States has made an actual attempt in recent decades, but in the end it failed due to unexpected circumstances.

For this purpose, Yuan also specially checked some specific actions of the US Mars landing program.

In 2018, NASA (National Aeronautics and Space Administration) of the United States began to launch the Survival Improvement Program for astronauts landing on Mars.

Plans include:

During the interstellar mission of more than 700 days, human health and behavior testing experiments were carried out for astronauts who may face risks such as cancer, osteoporosis, and immune problems in a long-term high-radiation environment;

the development of life support systems similar to growing food and recycling water on the surface of Mars and in space;

projects such as the construction of 3D printing modules in international transit space stations and spacecraft.

In 2022, NASA of the United States built the most powerful launch vehicle in history, the Space Launch System, and successfully launched a new spacecraft "Orion I", completing long-distance interstellar travel tests.

In 2025, NASA began building spacecraft capable of living and working on the surface of Mars. With only routine maintenance, the spacecraft will be able to obtain the resources to make fuel, oxygen and building materials from the natural environment of Mars to support human life for several years.

On August 22, 2028, NASA of the United States began the world's high-profile Mars landing operation.

In the early morning of the same day, the Mars II spacecraft was successfully launched.

Due to the constraints of the scientific level at that time, the earth technology could neither realize the energy-intensive "direct and direct" interstellar voyage, nor could it propel the spacecraft by launching a Mars probe (the Mars probe can reach Mars in 6 months at the earliest).

Therefore, the Mars landing plan chose the "most energy-saving route".

That is, with the Sun as the midpoint, it enters an elongated elliptical orbit around the Sun at a rate slightly higher than the second cosmic velocity (at this time, the spacecraft can fly in orbit with the help of the Sun's gravitational pull, which greatly reduces energy consumption). Then fly from Earth, which is at one end of the orbit, to Mars, which is at the other end.

On July 20, 2030, the Mars II spacecraft reached near-Martian orbit after nearly two years and was captured by Martian gravity.

Prior to landing, the Mars II spacecraft first made 10 full orbital flights along the periphery of Mars.

During this period, the astronauts collected a large number of extremely valuable Martian information images through the ultra-high-definition probe on the spacecraft.

Subsequently, during the fourth near-Mars orbit flight, NASA also conducted a landing rehearsal, and the "Mars II" spacecraft launched an unmanned spacecraft to collect several boulder samples from the surface of Mars and successfully recovered.

Faced with such a smooth start, the whole Earth thought that the Mars landing plan was about to be completed.

However, the weather did not fulfill people's wishes, and the surface conditions of Mars were prominent, and a three-month sandstorm broke out in the area where the original landing site was planned, with a wind speed of more than 180 meters per second (32.6 meters per second for a 12-level typhoon).

In the face of such harsh natural conditions, for the safety of the spacecraft's return journey, NASA finally had to regret the termination of the Mars landing program.

In the more than 20 years since, no country or organization has attempted to land on Mars
