Vol 4 Chapter 2370: Efforts to achieve "interstellar" travel

【Military Technology】【】
However, these rockets can only complete the recovery of the core first stage rocket, plus the recovery of the fairing at most. The core of the rocket and the second stage of the rocket are often not recovered. Why, because the technical difficulty and cost of core-stage rocket recovery is too high, and it is not worth it for many companies, including many institutions.
In fact, when we started this project, we also had such questions, is this project really worth it, and will it be better to make a new one for the final recovery cost?
But in the end after some discussion and debate, we finally decided to do it. In our view, this is both a technical issue and a cost control issue. The two have to be combined for this project to be able to get the cost.
That is to say, we need to develop a core-stage rocket with excellent technology, safety and reliability, and low manufacturing and use costs. We have mastered the return landing technology, but it is very difficult to add economy.
So in order to be able to overcome this problem, I know that everyone has worked hard for a long time. Fortunately, the emperor paid off, we succeeded, and today's success is enough to prove that our choice was right.
In addition to reducing costs, this technology can greatly save space junk in low-level and low-Earth orbits of the earth and keep the orbit clean. In fact, much of the junk in low-space orbit now is caused by the rocket debris of these launch missions. After these second-stage rocket wreckage is completed, it is abandoned in orbit. Some of them will fall into the atmosphere and burn up after a few months, while others can float in space orbit for a long time, and continue to communicate with others. Flotsam, space junk hits and breaks down into smaller space junk particles.
These space junk and tiny particles orbiting at high speed in low-Earth orbit cause great harm to human spacecraft in medium and low orbits, including some round-trip spacecraft.
If you are not careful, the spacecraft will be penetrated by a particle. This kind of space junk is too small for the ground to make predictions at all, and no one knows when it will be encountered, which has become a matter of luck.
At present, there are many examples of these space debris damaging spacecraft, including some satellites in orbit, which were completely damaged or even ended because they were hit by space debris debris.
Including the famous International Space Station, there have been several leaks due to the attack of space debris debris, which has greatly reduced the operating life of the National Space Station and accelerated its aging.
So through this technology, we can realize the reuse of secondary rockets. Start from ourselves, reduce the generation of space junk, and consciously maintain a clean space environment.
I hope that under our leadership, all countries and major aerospace companies can truly take responsibility and consciously maintain a clean space environment. This is not only for everyone, for us all to have a clean space environment, but also for ourselves and our children and grandchildren.
I don't want to see our descendants, the earth's orbit is full of garbage, just like the ocean today. It is very easy to pollute, but it is very difficult to clean up. It may take many years, hundreds of thousands of years or even tens of thousands of years to decompose and digest all these pollutants.

Speaking of this, Wu Hao paused for a while, then looked at the audience again and said, "Besides, the successful development of the reusable two-stage rocket has laid a solid foundation for our follow-up space exploration projects.
In the future, we will invest a lot in space exploration, especially some major projects, which require us to have our own safe, reliable and cheap launch vehicles to undertake the transportation tasks of these major projects. The reusable two-stage rocket technology will play a crucial role in reducing the cost of transportation in the future.
To give a very simple example, we have already implemented a large number of transportation tasks in the construction project of the lunar scientific research station. We need to transport all kinds of equipment and supplies from Earth to the moon. If it is transported by ordinary launch vehicles, it will be a very large cost.
But if we use this fully retractable launch vehicle, we can reduce the entire launch transportation cost to one-tenth or even less.
So for everyone, this Jianmu-2 reusable core two-stage rocket is just the beginning. We need a core two-stage rocket with stronger carrying capacity. Our next step is to develop it as soon as possible and apply it to Jianmu. A reusable core two-stage rocket in configuration VII. "
With that said, Wu Hao glanced at everyone in the audience, and then continued: "In addition, we have to develop our manned aerospace vehicle, or aerospace aircraft on this basis.
It will be a new generation of space shuttles. This manned aerospace vehicle is very similar to the technical principle of the reusable core two-stage launch vehicle that we are currently experimenting with. It is also carried on the first-stage rocket, which is pushed to a suitable height by the first-stage rocket, and then ignited by it and continues to rise to the relevant orbit.
Then after completing a series of space missions in space ~EbookFREE.me~ return to Earth, gliding and landing on the runway like a space shuttle.
And it can also increase the number of launch vehicles at the bottom according to the height of the orbit, which can be a single core first stage rocket, or a core first stage plus two or four booster rockets. It can even become a three-stage rocket, and the bottom is composed of two-stage launch vehicles, so that it can provide enough thrust for the manned aerospace vehicle, so that it can rise to a higher orbit, or even enter the moon. Orbits, or earth-fire transfer orbits, to achieve interstellar travel.
Wei Wei explained that the interstellar travel here refers to the travel between stars and stars, not the interstellar travel between galaxies as everyone literally understands. "
hehehehe...
A knowing weakening erupted from the audience.
As for Wu Hao, he said with a smile: "At the same time, through this fully reusable manned aerospace vehicle, we can greatly reduce the cost of ferry tickets between heaven and earth, so that we can travel to the sky. It will no longer be the patent of the rich. In the future, as long as everyone is willing, you only need to spend a small fee to complete a real sky trip.
Instead of the so-called space travel launched by some commercial aerospace companies, it is just a so-called space travel to experience the pleasure of weightlessness for two or three minutes near the Carmen line at an altitude of 100 kilometers.

Our space travels will take passengers to travel around the Earth in space for several days, to space stations or even to our interstellar flights to the moon or even Mars for vacations. "
