At an air base in the desert of Nevada, dozens of technicians are nervously staring at the test situation in front of them. Pen & Fun & Pavilion www.biquge.info

A laser beam was launched from the ground into the sky, and a few seconds later, it was launched back from the sky, and the staff nervously checked the data packets sent back, analyzed the bit error rate, checked the communication protocol, and tested and adjusted the transmitting equipment.

And in the Pentagon, thousands of miles away, generals in military uniforms or politicians in suits and leather shoes are also waiting for the results this time.

At the emergency cabinet meeting held some time ago, the United States made a major resolution that it would devote its national efforts to develop space technology and strive to colonize Mars as quickly as possible!

At the cabinet meeting, the current president spoke in a very firm tone: "400 years ago, our ancestors left Europe on the Mayflower and came to this new continent, and it is the descendants of these people, we, who founded this great country. And 40 years ago, we had an arms race that knocked our opponents into the abyss and truly became the greatest country in the world. And now, a new round of challenges is coming, landing on Mars, colonizing Mars, is a greater thing than discovering America, Mars is our new America, whoever controls Mars, who controls the future!"

After this meeting, the president issued a presidential decree and established the "Mars Colonization Committee", and the members of the cabinet either sent cronies or personally participated in this new round of the arms race.

There are already many options for landing on Mars. The United States has designed a technically feasible landing technology on Mars several decades ago, but it has to be shelved because of cost and environmental factors, which is the "Orion Program" of the United States.

This plan can be called a perfect combination of whimsy and scientific rigor, and it uses nuclear propulsion, but it does not propel steadily, but constantly drops nuclear bombs on the back of the spacecraft!

In the process of the flight of the Orion spacecraft, the Orion project continued to drop a miniature nuclear bomb attached to the plastic disc, and at the moment of explosion, the nuclear bomb plasmized the plastic disc to form a huge impact force and push the spacecraft forward.

This scheme seems ridiculous, but in fact it is very effective, and the two major factors that constrain it are the cost and the harm caused by the nuclear explosion.

In order to avoid the radiation hazards caused by a nuclear explosion, the spacecraft must first be sent to outer space using an ordinary chemical rocket, and then this special nuclear engine must be activated.

The Orion planned spacecraft, a super behemoth, had to have a wide enough cross-section to generate enough thrust, and before the advent of the Earth Trebuchet and the Space Elevator, it was almost impossible to launch with an ordinary rocket, and the cost was simply too high......

But now, all obstacles have been removed, and the biggest obstacle restricting human beings from flying into space, the earth's gravity, has been wiped out by the lazy god system with the power of science and technology.

The "New Orion Project" has mobilized 77 of the top laboratories in the United States, with hundreds of project teams, and the first to test is laser communication!

In plain terms, this is an experiment that the president is paying close attention to, and it is a political task that cannot be missed!

In order to ensure the success of the test, NASA technicians set up five devices in five places in the United States to transmit and receive signals, and immediately selected a certain device as a base station according to the weather conditions.

Today's Nevada, with a sunny wind and cloudless skies, is the best weather for laser communication experiments.

The signal transmitter of the communication base station is a powerful laser transmitter that can modulate the signal to the laser, and the receiving end is a huge astronomical telescope to reduce the bit error rate of the signal.

At the other end of the test, a satellite orbiting the moon, will transmit information from the Earth to the moon and back again, a total distance of 800,000 kilometers, even at the speed of light, which will take nearly three seconds to complete.

This is the basic reality of inter-universe communication, which can be communicated over distances and times far beyond the scale to which humans are usually exposed.

It's like going back to the days before the advent of the telegraph, when communication was basically by roaring and transportation was basically by walking.

But when landing on Mars, communication comes first, and without communication capabilities, there is no way to know the situation of the spacecraft in the universe in time, and there is no way to help them deal with emergencies.

In the vast and endless universe, there are violent electromagnetic waves everywhere, and the traditional communication method of using radio waves can basically rely on the blind to transmit information.

However, with the current laser communication technology, the transmission of tens of millions of kilometers, or even hundreds of millions of kilometers, is subject to countless interferences, which is almost the same as relying on Mongolia.

Therefore, if the test is successful, the United States intends to use the multi-satellite chain relay model to launch a series of relay satellites between the Earth and Mars to ensure the reliability of communications.

You can even directly let the Mars spacecraft automatically release several relay satellites during the flight, and they have all thought of the code name, which is called "breadcrumbs".

Longer distances mean better pointing and following techniques, more powerful laser beams, better communication protocols, and more bandwidth to emit redundant information for error correction.

Laser beams launched from the ground to space are also affected by atmospheric density, atmospheric turbulence, ground dust, clouds, and airborne particles, which can sometimes be called fatal, and involve countless technologies to eliminate interference.

Therefore, even in the United States, this laser communication technology has never really entered the practical stage.

And to remove these obstacles, every technological advancement can be called a revolution in related fields.

But in any case, the United States has dominated the world for nearly 100 years, and in this 100 years, they have accumulated the best universities, the best talents, and the most competitive research and development institutions in the world. Perhaps in terms of quality, the lazy god system occupies an extreme advantage, but in terms of quantity, the United States is the one who really has the greatest advantage!

It's only been a year since the rise of the lazy god system, and now, the best talent in the world is still in the United States!

The United States, for this experiment, is bound to win!

Rounds of testing are underway, starting with a single image and then scaling up to a short set of videos, in the process of continuously adjusting the communication protocol to achieve a balance between bit error rate and channel utilization......

In this test, the carrying limit of the channel is 1000M, and the reliability and redundancy of the information are positively correlated, that is, the more calibration information is added to the transmitted information, the more reliable the information can be ensured, but it will also affect the utilization rate of the channel.

The results of the test are gratifying, as long as you make a little more progress, you can enter the practical stage!

With an open supply of money and talent, solving these technical problems is just around the corner!

Hearing the news, cabinet members and military generals smiled one by one.

When he was having fun, an official from the NSA (National Security Agency) said, "The lazy gods are also testing their own 'laser communications', I wonder what their results are?"

When the experts in NASA (National Aeronautics and Space Administration) heard this, they almost rolled their eyes to the back of their heads.

Everyone is just one letter apart, they are born from the same root, why are they in a hurry!

Why don't you open which pot and which pot you mention?

It's just a matter of asking questions, can you not ask such a sensitive question!

"Uh, our experts are following up on the assessment and should be writing the assessment report now......"

"What about the report?" asked the Minister of Defense, who was sitting at the top, with a grim face.

"Uh, I'm going to urge it......" The NASA official immediately made a phone call to the base in Nevada, and after the phone was answered, the other side heard that it was a report, and immediately shouted: "I'm sorry, our report is not finished yet, and there is really no way to make a conclusion about the current technology of the Lazy God Department, their technology is incredible!

"In order to evaluate their technology, we mobilized a test drone control system...... "He turned his head and looked a short distance behind him.

A technician in his forties, dressed in a heavy suit, wearing a giant VR (virtual reality) headset, was dragging a wire around the room, screaming and screaming.
