Chapter 2370: Strive to realize 'interstellar' travel
However, these rockets can only complete the recovery of the core first-stage rocket, and at most the recovery of the fairing. However, the core-secondary rocket of the rocket is often not recovered. Why, because the technical difficulty of recycling the core-secondary rocket is too high.
It is large and the cost is too high, so it is not worth it for many companies, including many institutions.
In fact, when we started this project, we also had this question: Is this project really worth it? Will the final recovery cost be worse than manufacturing a new one?
But in the end, after some discussion and debate, we finally decided to do it. In our opinion, this is both a technical issue and a cost control issue. The two must be combined to achieve cost-effectiveness for this project.
In other words, we need to develop a core-two stage rocket that is technically advanced, safe, reliable, and cheap to manufacture and use. We have already mastered the return and landing technology, but it is very difficult to add economics.
So in order to overcome this problem, I know that everyone has worked hard for a long time. Fortunately, Huangtian paid off and we succeeded. Today's success is enough to prove that our original choice was right.
In addition to reducing costs, this technology can also greatly save space debris in low-Earth orbits and keep the orbits clean. In fact, a lot of garbage in low-space orbits is caused by the debris of rockets from these launch missions. These two
After completing the carrying mission, the wreckage of the first-stage rocket 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 interact with other floating objects.
, space junk collides and breaks down into smaller space junk particles.
These space junk and tiny particles flying at high speed around low-Earth orbit will cause great harm to human beings' medium and low-orbit spacecraft, including some round-trip spacecraft.
If you are not careful, the spacecraft may be penetrated by a particle. This kind of space junk is so small that it is impossible for the ground to predict it. No one knows when it will encounter it. This has become a matter of luck.
Currently, there are many examples of spacecraft being damaged by these sky debris, including some satellites operating in space orbits that were completely damaged or even completely disabled due to being hit by space debris.
Including the famous International Space Station, there have been several leaks due to attacks by space debris, which has greatly reduced the operating life of the National Space Station and accelerated its aging.
Therefore, through this technology, we can realize the reuse of the second-stage rocket. Starting from ourselves, we can reduce the generation of space debris and consciously maintain the cleanliness of the 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, so that we can all have a clean space environment, but also for ourselves.
It is also for our future generations.
I don’t want to see that in our future generations, the earth’s orbit will be full of garbage, just like today’s oceans. It is very easy to pollute, but very difficult to clean up. It may last for many years, hundreds of thousands or even thousands of years.
It takes tens of thousands of years to decompose and digest all these pollutants.
Speaking of this, Wu Hao paused briefly, then looked at the audience again and said: "In addition, the successful development of the reusable two-stage rocket will lay a solid foundation for us to carry out subsequent space exploration projects.
In the future, we will invest heavily 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. And reusable two-stage rocket technology
, will be a crucial project for us to reduce shipping costs in the future.
To give a very simple example, the lunar scientific research station construction project we are already implementing includes a large number of transportation tasks. We need to transport various equipment and materials from the earth to the moon. If ordinary launch vehicles are used for transportation, then this will
It will be a very large cost.
But if we use this fully retractable launch vehicle, we can reduce the entire launch and 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 focus is to develop it as soon as possible and apply it to Jianmu
A reusable core two-stage rocket of configuration No. 7."
With that said, Wu Hao glanced at everyone in the audience, and then continued: "In addition, we also need to develop our manned aerospace vehicle, or aerospace plane, on this basis.
It will be a new generation of space shuttle. This manned aerospace vehicle is very similar to the technical principle of the reusable core two-stage launch vehicle we are currently experimenting with. It is also mounted on a first-stage rocket and consists of a
The first-stage rocket pushes it to the appropriate height, and then ignites it and continues to rise to the relevant orbit.
Then after completing a series of space missions in space, it returns to Earth and glides and lands 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. It can be a single core first-stage rocket, or a core first-stage rocket plus two or four booster rockets. It can even be a three-stage rocket.
, the lower part is composed of a two-stage launch vehicle, which can provide enough thrust for the manned aerospace vehicle, allowing it to rise to a higher orbit, or even enter a lunar orbit or a ground-fire transfer orbit.
, realize interstellar travel.
Please explain slightly, the interstellar travel here refers to the travel between stars, not the interstellar travel between galaxies as everyone understands literally."
Hehehehe...
A knowing weakening erupted from the audience.
Wu Hao, on the other hand, said with a smile: "At the same time, through this manned aerospace vehicle that can be fully reused, we can greatly reduce the cost of air tickets between the sky and the earth, thus making travel to the sky possible.
The price will be lowered. It will no longer be a patent for 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.
Rather than the so-called space travel promoted by some commercial aerospace companies, it is just a so-called space travel to experience the pleasure of weightlessness for two to three minutes near the Kármán line at an altitude of 100 kilometers.
"Our space travel will take passengers around the Earth for days in space, to the space station and even on our interstellar flights to the moon and even Mars for vacations."
