Launch a spaceship to the sun.

Designed to look like a doughnut, it should be that this shape can provide some power. Today's spacecraft can fly in space, but for a short time, because fuel is limited.

Russian scientists are developing a doughnut-shaped spaceship, which can get energy directly from the sun and then reach the farthest place in the solar system in a very short time. According to scientists' description, in the middle of this doughnut-shaped spaceship is a solar panel, which will be coated with a special substance. When it approaches the sun, the substance will start to evaporate rapidly, and then the spacecraft will be able to accelerate the injection without carrying a large engine. In fact, this is a very good idea. After all, human spacecraft can go into space now, but energy is the most important issue.

To realize the spaceship in the movie, what we have to solve is how to improve the ratio of power to fuel weight. Now, as long as it is manned space flight, it needs large rockets to have enough fuel to send such a large load to the scheduled orbit. However, the more fuel, the greater the rocket thrust required. Once the thrust is greater, more fuel is needed, so this problem has always been a difficult problem in the world.

In terms of spacecraft, human technology has matured, so the biggest technical problem is fuel. However, with the development of Xiaoyao technology, the thrust-to-weight ratio of our engine is constantly improving. Within 50 years, mankind should still rely on the current rocket engine to increase the load of spacecraft by increasing the thrust-to-weight ratio. Of course, if there is a breakthrough technological innovation in the future, the universe will no longer be mysterious to us.
