Earth, Houston Space Center, USA.

"The latest news came from the Noah... It's here! It's here! They're here! They're here! They're here..." The female staff staring at the screen was first silent readers. When she saw the content of the news clearly, she was so excited that the news quickly spread.

When Houston Space Center received the latest news from "Noah", the entire Nasa headquarters was in full swing, and even Charlesbor was inevitably excited. The news was spreading at an astonishing speed, and Nasa spread the news as soon as possible. The news reports on the world's front-page headlines were almost all about the successful arrival of "Noah" on Mars.

The American media have even reported this overwhelmingly.

This is undoubtedly a phased victory. The five astronauts carried by the Noah have deserved to further refresh the "horizon" of mankind. The last time I went to the farthest was the moon, and this time it was the more distant Mars, which is of extraordinary significance.

In the capital of Washington, the White House also sent a spokesperson to congratulate the periodic victory.

...

On June 22, when the American "Noah" successfully and safely arrived in Mars orbit and its news came back to Earth caused a sensation around the world, the "Mars Express" that had already set off in mid-May has also sailed for more than a month for a long distance, and its range has exceeded 2.9 billion kilometers.

The propulsion system of the Mars Express is very special. Compared with the conventional ion engine drive, which is driven by a conventional ion engine, which emits argon atoms backward at ultra-high speed to obtain thrust, the propulsion system of the Mars Express has a somewhat opposite taste. Its propulsion engine is not only a conventional fuel thruster with a rear, but a front engine, which uses thousands of lasers to illuminate hundreds of thousands of lasers to propel the Mars Express and its "Firefly".

Although a reverse thrust is generated when the thousand-group lasers are started, the thrust kinetic energy generated by the light sail is completely acceptable. Only a small part of the thrust can offset the reverse thrust. The acceleration of the light sail pushes the entire object is indeed very fast, but it does not seem too shocking. On the one hand, it is an energy problem, and on the other hand, it is also a factor that has astronauts on the spacecraft.

Despite this, during the long sailing stage, the acceleration of more than ten times respectively, the continuous acceleration of the entire spacecraft in batches can also bring a very fast acceleration to the spacecraft after a long period of accumulation. In theory, under the ideal state of sufficient material strength and energy output, the continuous acceleration can make the entire spacecraft infinitely close to the speed of light. Infinitely approaching the speed of light only requires continuous acceleration for 8 months. Of course, this is an ideal state.

But these problems are not designed as a front engine factor, which is the size of the entire aircraft, including the outpost base to be established on the Mars surface and a surface crystal cutting laboratory, plus two landing vehicles, and other miscellaneous materials.

The total amount of the entire aircraft is already quite amazing. The "Flower" operating in Mars orbit alone has reached a volume of nearly 1,500 tons. With other parts, the entire aircraft is almost close to 4,000 tons, which is equivalent to half of the "Tiangong Ring Orbit Star Port".

With such a huge size, only by using the front engine can you safely take this big guy to shuttle between the stars...

Just imagine if it is a conventional propulsion system, such as a rocket-like rear-mounted aircraft, its hull structure and material properties must be strong enough to cope with the thrust of the engine. In other words, the entire aircraft structure must be built like a skyscraper with a solid structure like a sturdy middle and bottom layer to ensure that such a huge spacecraft will not collapse and fall apart when facing strong thrust.

This is also the reason why the rocket's body shape and outline are structured like spires, with a small upper end and a huge middle and lower layer. For example, the American "Saturn 5" and the American "Noah" are designed in this way.

But the front engine is very different. The hull does not need to be designed as thick and strong as a super heavy rocket or building. The biggest requirement is to be as resistant as a rope. This is also the biggest reason why the total length of the Mars Express and the Firefly once exceeded 1,000 meters, and the structure seemed so slim.

The design of the front engine can greatly reduce the weight of the hull structure, making it possible to sail across long-distance interstellar spacecraft. Going to the asteroid belt mining operations and transportation is not an out of reach. This is undoubtedly of great significance to interstellar navigation.

Otherwise, why is the American "Noah" so "small"? Why is it tower-shaped gyro? And due to the capacity, the American "Mars Plan" has to be divided into three times, and a one-way journey takes nearly half a year. A round trip between Earth and Mars plus the mission time takes almost a year, and a golden voyage stage of relative distance has to be waited for. With the current changing technological changes, time is so precious.

It does not mean that Americans do not have the financial resources. Just the giant companies participating in the "Martian Mission" are not without money, and the United States is not without money.

The real reason is that the field of laser technology is not as good as China, and the field of light sail technology and solar panels are also far ahead of China. The solar panels like the vast ocean in Qinghai are enough to illustrate some problems.

Not to mention the issue of energy supply, for Americans who do not have purple source crystal, this is a truly ununsolvable knot. Not to mention the problem of mature laser technology, it is that if you want to obtain enough thrust, you need more fuel to supply the energy output of the laser column. Carrying more fuel means that the volume of the spacecraft needs to increase, which requires stronger thrust. Obviously, this is a vicious cycle.

But the purple source crystal helped cmsx to unravel this biggest dead cycle, that is, to reduce the volume of the spacecraft while not losing energy supply.

At this moment, in the space of "Flower Fire".

Ren Hong was sitting on the desk in the centrifugal cabin and staring at the dizzying data on the screen without saying a word. This time, he spent a lot of money and traveled to Mars not far from hundreds of millions of kilometers away, with the purpose of obtaining the purple crystal on it.

But obviously, it is not easy to get these fatal crystal ores on Mars. What Ren Hong is most worried about and concerned about is how to cut them out from such a large piece of purple stone. And according to the current understanding of the characteristics of purple source crystal, it is estimated that the idea of ​​collecting scattered crystal fragments at the fall point is a bit unrealistic.

Even nuclear bombings cannot decompose this stone. This time, the huge "terminator" fell to the surface of Mars, and perhaps even pieces of debris would not fall off, which means that manual cutting from this big guy piece by piece.

Ren Hong did invent the technology of cutting purple crystal, namely the "condensation cutting method", but it is advantageous in the favorable external environment on the earth and the size of cutting objects. It is really urgent to catch the head when facing a "terminator" calculated in kilometers.

This is Mars, not the Earth, and the environment is harsh. It is also a relatively difficult problem to create an ultra-low temperature environment with infinite close to absolute zero. The unavoidable harsh actual environmental requirements faced by the unavoidable harsh environment require a movable low-temperature laboratory to meet it.

Fortunately, he currently has a large amount of energy-filled melon crystals. The series of activities to be carried out on Mars require massive amounts of energy as support. Whether it is outpost bases, mobile cutting laboratories, or mobile laboratories that manufacture ultra-low temperature environments, it drives it to operate as a major consumer who swallows energy. Fortunately, high-energy storage melon crystals can support the huge energy consumption of a series of equipment.

"Old...uh no, Professor Wang. 7 minutes ago, news came from the Earth Command Center." At this moment, Xiao Kerui, who played his assistant role, came to him.
