Jinling space launch center.

A huge and magnificent space plane has been crawling on the launching runway.

Its name is Xiaguang, but it's different from the one a few years ago. In order to adapt to long-distance flight and more flexible launch mission, the Institute of Aerospace Science and technology of Jinling Institute of higher learning redesigned its fusion energy supply unit and high-power Hall thruster, which improved its cruise mileage and engine stability at the expense of limit speed.

Now it's not Mars, even the asteroid belt between Mars and Jupiter can easily reach in a month. But now the moon orbit construction committee doesn't need to send people to such a far place. If it only collects rock samples, it can be realized by unmanned detector.

As for the pilot of this flight, he is also the original crew of Mars rescue, and the only astronaut in the crew who has experience in Mars orbit cruise.

With an experimental device sealed in a metal cube box being sent into the cargo compartment, the entire spaceplane has completed the final launch preparations.

Liu Biao and Xu Zhenghong, who have already put on the spacesuit in the cabin, climb up the gangway under the ground crew's witness, enter the interior of the spaceplane, take their seats in the main and co pilot's positions respectively, and connect the spacesuit to the cabin health protection system.

"A long lost trip to Mars."

"I don't know if I can see the wreckage of BFS in the past."

with a grin, Xu Zhenghong, who checked the normal instruments in the cockpit, said with a smile: "ha ha, it's been more than a year, probably I can't see it."

Liu Biao joked, "if the situation allows, I'm not sure we can get it back."

During the last rescue operation, NASA worried that China would obtain the secrets of the BFS spacecraft, and actively crashed the BFS spacecraft hovering in orbit when Xiaguang arrived at Mars.

Nevertheless, the coordinates of the crash were recorded by them. If the fuel is enough, it's not difficult to land on Mars and get some local products.

"The situation probably won't allow, why do we have to manage a lot of rags, and still with troublesome rags?" opened the power output gate, looked at the rising magnetic counter, Xu Zhenghong pushed the ignition switch and switched to the communication screen of the ground command center at the same time, put on a serious tone and said, "here is Xiaguang, we are entering Into the take-off orbit. "

"Roger, this is the ground command center. Everything is normal in the sky. The launch plan goes on. Good luck!"

The jet black engine was lit by a blue flame in an instant. Driven by the high-temperature plasma jet, the huge fuselage began to slide forward, and finally pulled the blue glow to the sky. Along with people's expectation for the future on the earth, it has brought to the fiery red planet tens of millions of kilometers away.

In the auditorium outside the launch center.

Looking at the sky plane disappearing at the end of the cloud, physicists and journalists from all over the world made amazing sounds.

With his back to a clear sky, the BBC reporter, with an almost exaggerated expression, reported the scene to the camera.

"A sky plane, about two-thirds the size of a Boeing 777, took off from the runway with a blue glow and disappeared into the sky behind me."

"I can't use words to describe the shock in my heart, not because of its speed, but because it subverts my understanding of space launch."

"Maybe it's too late to say that, but I never thought Maybe NASA people have never thought that even electric propulsion can produce the same power as chemical engine under the catalysis of controllable fusion! "

"I almost forgot to say that imcrc's Z particle clock has successfully passed through the troposphere and is moving towards the edge of the atmosphere. If all goes well, it will reach the orbit of Mars in two weeks, put down the Z particle clock, and test Professor Lu Zhou's hyperspace theory... "

Not far away.

A slightly younger, student looking young man stood next to Professor Witten.

It seems that for fear of missing a moment, he stared at the sky for a long time without blinking, until people began to end gradually, he took back his sight and looked at Professor Witten and asked.

"Professor..."

"What's the matter?"

"If he does exceed the speed of light, what does that mean?"

"It means that he may be greater than Einstein..." After a pause, it seemed that his statement was not accurate enough. Witten added in a serious tone, "correct it, not possible, but yes."

The news of the launch of Z particle clock spread all over the world.

According to the navigation plan, after the first z-particle clock detector is put down after arriving at the synchronous orbit, Xiaguang will go to the Moon Palace, and after completing the "fuel" replenishment there, continue to fly to Mars orbit.Just as the eyes of the whole world are focused on the sky plane passing through the edge of the atmosphere, the dean's office of Jinling Institute of higher learning, not far away, is quietly thinking about the formula on the whiteboard.

At this time, the knock sounded from the door.

"Come in, please."

The door opened and a familiar figure entered the office.

"You are here," Luo Wenxuan said curiously, looking at the blank board filled with calculations he could not understand at all. "I thought you would at least stand in the command tower of the launch center at this time."

"What's the point of standing there?" The sight did not move away from the whiteboard. The boat smiled lightly and said, "I will not affect the success rate of the launch if I am not at the scene. What's more, it's just a trip to Mars. It's not the first time for us. There's nothing to remember. "

Luo Wenxuan: "what are you doing?"

"Make a final check on the calculation results..." After a few lines of arithmetic were added to the whiteboard, the boat pondered for a while, and then said, "or try to make it more perfect."

Luo Wenxuan: "it's amazing that you are not excited at all. You are even in the mood to count these things."

Lu Zhou: "is there anything exciting?"

Luo Wenxuan said jokingly: "I feel that a physicist greater than Einstein is about to be born, and every explorer in the new era of navigation will shout his name before setting sail, praying for the safety of travel. In the future, if any spacecraft goes out of the solar system and breaks down, the passengers will not call God the old man's name, but "gtmd, land boat."

Hearing this interesting statement, Lu Zhou couldn't help smiling.

"That's too much. Z particle is just a breakthrough in hyperspace theory. Whether it can be the key to solve the problem of interstellar travel finally depends on how people in the future understand this theory. It doesn't necessarily mean the advantage to start at this time, just like DC and ac. although the former was born first, it is the latter that finally wins people's favor. "

"But everyone will remember Faraday's contribution to the world."

Lu Zhou: "I don't deny that I have to give the discoverer a little honor for such a bad thing."

Luo Wenxuan shrugged his shoulders and asked, "then what are you doing for the sake of doing something that is not good and will take great risks?"

Lu Zhou: Frankly speaking, it's because of interest

Luo Wenxuan is slightly stunned, then smiles.

"It's really like your answer."

Lu Zhou: "are you here to talk to me?"

"Of course not."

With that, Luo Wenxuan took a card out of his pocket and handed it to Lu Zhou.

Looking at this beautifully made card, Lu Zhou raised his eyebrows curiously, put down the marker in his hand, took it over, unfolded along the fold line, and glanced at the above contents.

"This is?"

"An invitation letter," Luo Wenxuan explained with a shrug as he looked at the boat. "I don't know if you are interested in it, but I'm here in Jinling, so I'll take it to you by the way."
