"Sun Tan, do you know what this thing is?"

"I've talked to a couple of rocket engineering scholars about which Starship is most likely to be the next target, and they mentioned that possibility, which is a combined energy spacecraft with two propulsion systems, laser and Bassard ramjet power." Sun Tan climbed along the wreckage of the building to the end of the strange spaceship, watching in amazement.

"Is the Barsad ram power now achievable?" Ninaga was surprised.

"I don't know, it's supposed to be still experimenting, I don't know where it has been." Sun Tan rolled into the cockpit of the spaceship, which was still very new, and some of the components were obviously freshly assembled, and the researchers had temporarily hidden it when the war broke out.

Mark has heard of laser power, which is the hottest research direction in recent years, more advanced than the propulsion power used by the human space fleet, laser is actually a common name, its real name is called high-energy pulse laser propulsion, although in theory there is no beyond the essence of working fluid propulsion, but laser power is already the limit of working fluid propulsion, it propels itself forward by generating a series of powerful pulsed explosion waves, when the propellant as a working fluid flows to the laser agglomeration area, Under the action of a high-energy pulsed laser, the propellant expands rapidly, heats up, and converts into a high-temperature plasma, forming an explosion wave supported by a laser, which theoretically can reach two percent of the speed of light.

Although it is much slower than the interstellar legends in human imagination, this is already the only way for humans to reach and move towards the starry sky, warp speed and wormhole technology are still unattainable myths, although laser power is far inferior to them, but at least human beings stretch out their hands towards the starry sky, and interstellar travel is no longer an unattainable utopia.

In the case of sufficient energy, it will take two hundred years and three generations for this spacecraft to go to the nearest Centauri galaxy to the solar system, but the Voyager 1, which was launched in 1977, will not arrive until 42,000 years later.

But what they said about the Basad ramping power, Mark had never heard of, it seemed to be a very unpopular doctrine, and Nina saw his incomprehensible expression, so she was able to popularize science with him.

"Basad ram power is a concept proposed by American physicists in 1960, in essence it is a working fluid propulsion technology, this thruster is a magnetic beam fusion ram thruster, but the difference is that it can continuously collect and compress hydrogen in interstellar matter through a huge magnetic field, 75% of the ordinary matter in the universe is hydrogen, even in space, the content is still not low, until it is collected enough to occur nuclear fusion, and then the spacecraft is pushed forward by reaction force, Maintaining a constant push in this way, it is not fast, but it has excellent endurance, and as long as the collection tower is still intact, there is never a need to worry about running out of energy, making it ideal for long-distance flights. ”

"So it's a ship that combines the best of both worlds, with laser power to get the ship into a fast enough speed, and then the Bassard ramjet power can sustain the endurance of the journey...... In this way, it is perfectly designed. "Mark is also very smart and basically understands everything.

"But it still hasn't solved the problem of working fluid, if the electromagnetic drive engine comes out, then it can completely solve the problem of space flight, as a transitional form of experimental aircraft, it has achieved its own meaning of existence."

Sun Tan was very obsessed fiddling with the operating console inside, Mark kept reminding him not to move, he still has palpitations when he thinks about the explosion just now, Nina actually didn't really start the engine, just adjusted it with minimal effort, but the pulse explosion wave of this spaceship is not a joke, it is more powerful than the tank artillery of the rebel army, and it can be used directly as a weapon.

"Don't worry, of course I'm measured." Sun Tan said: "Don't look at it as small, the ambition of the people who developed it is not small, this is a spaceship that can carry out ultra-long-distance flight, and there is also a place to install a hibernation chamber inside, and the flight in the solar system is simply trivial." ”

"We can't take the problem with us...... Mark worried, the Piff is not guilty, they obviously don't have the ability to receive this spaceship now, and in this situation, I don't know how many people want to get this spacecraft that can easily escape from the moon.

After discussing it for a while, Mark decided to hide it first, not to be discovered by others for the time being, maybe they will use it again in the future, Mark drove out the engineering vehicle in the geological center that had not been damaged, and together with Nina, pulled it into the underground parking lot of another block with two cars, and now there is no one here, and they simply covered it with building materials, and it should not be discovered for a while.

Then the main task returned to rescuing the earth, the amplifier that Mark and they had built with great difficulty was damaged, and now they have no means to contact the Newborn, Sun Tan had already told Captain Murong Nan everything he knew before, and he also believed that the Newborn would definitely take action, but after all, he was still a little worried.

"Is that all we can do?" Sun Tan looked at the trajectory of the Xinsheng in the air and sighed: "Although I know that they will definitely do better than us, but I am still a little unwilling, it would be good if I could go up to the Xinsheng, I also want to participate in the research and development of super-distance communication, and now it seems that there is no chance." ”

"Didn't you just say that we have a spaceship." Mark smiled and said.

"Forget it, don't make a fuss, we don't even have the technology to fly a plane, and we still have a spaceship."

"Maybe it's autopilot, not a new concept spaceship." Mark touched his chin and fantasized that he couldn't help but be excited when he thought about the scene of maybe being able to drive a spaceship to the stars in the future.

"If the self-driving technology is so good, you don't have to go to work every day to drive a mining truck." Nina splashed him with cold water.

"Yes...... But it will definitely come true in the future, I originally thought that the exploration of the stars was far away from us, and we would still be in the solar system for a long, long time, but I didn't expect to see the day when it came...... Why do you keep looking at me and making people hairy? ”

Nina's eyes narrowed into a beautiful crescent moon, and said, "I think you are very interesting, you seem to have stars in your eyes, I have always been very good at divination, I don't know if you believe it or not, I can predict that your future must be full of wonderful and infinite possibilities." ”
