A movie "Hitting the Sun is HARD" that shows how difficult it is to put nuclear waste on the rocket and throw it away in the sun

Generated from facilities such as nuclear power plants handling radioactive materialsRadioactive wasteThe disposal method called burial disposal is adopted in many countries in many countries, but there is concern about the environmental impact when filling in the ground. In the past, a method of launching it with a rocket and drawing it to the gravity of the sun was considered, but it was rejected. So how easy is it to put the nuclear waste on the rocket and throw it away in the sun, a movie that explained the movie "Hitting the Sun is HARD"Has been released.

There are a lot of radioactive waste hidden in the danger of thousands of years to the earth on the earth, but the best disposal method has not been found yet.
There is an idea of "Do you want to put radioactive waste on a rocket and throw it away in the sun?" This is a tremendously difficult disposal method.
There is a danger in the idea itself of placing radioactive waste in the rocket itself. There is a danger that the rocket will explode at launch, and if the rocket carrying the radioactive waste explodes, the effect on the earth is immeasurable.
However, in reality, the act of going to the sun itself is extremely difficult.
Since the earth is being pulled by the gravity of the sun, it may be easy to shoot radioactive waste into the sun with a rocket, but the earth revolves around the sun at a constant speed and straight from the earth Even if you shoot a rocket toward the sun, you will not hit it.
In order to shoot a rocket from the earth into the sun, it is necessary to slow the revolution speed, but there is no way to slow down the Earth's revolution speed.
If you can not lower the Earth's revolution speed, there is a way to fire the rocket in the opposite direction to the Earth's revolution. The revolution speed of the earth is about 30 km per second, and in order to make the rocket crash against the sun, it is necessary to fire the rocket at 30 km / sec toward the direction opposite to the direction of revolution of the earth (vector in the opposite direction).
If you fire the rocket at 30 km / s in the direction opposite to the direction of the Earth's revolution, the speed will be canceled and it will fly straight to the sun. However, the 30 km / sec speed is a tremendous speed of 108,000 km / h.
Also, the closer the distance to the sun is, the stronger the gravity will be. For example, Mercury is closer to the sun than the Earth, but as the gravity of the sun is strong, the revolution speed is also faster than the Earth at 48 km / s. Therefore, if you think to shoot a rocket from Mercury in the sun, a speed of 48 km / sec is necessary, and although Mercury is closer to the Sun than Earth, it is more difficult to shoot a rocket than the Earth It will be.
The revolution speed of Pluto, which is located far from the sun than the Earth, is only 4.7 km per second. In other words, because the speed of the rocket may be low, it is better to launch the rocket from Pluto, which is located away from the sun than the earth.
In order to shoot the rocket towards the sun more easily it is necessary to go out once outside the solar system where the revolution speed becomes extremely low, rejoin in the direction opposite to the direction of travel, slow down the orbital speed, and drop it to the sun as it is There is a method.
NASA was planning a strategy of slowing down to the sun by swinging by once to Jupiter instead of going directly to the sun from the earth in 2005 sun investigation.
Actually, I went to Venus instead of Jupiter, but the reason was that we were saving fuel.
However, in order to shoot a rocket in the sun, setting the launch speed of the rocket to 30 km / sec or exiting the solar system once,It costs too muchIt seems that it is considered impossible. In the first place, putting radioactive waste on the rocket at the time the rocket may explode is too high risk.
