v10 Chapter 2727： World-class problem (2/2)
He needs real materials!
”Professor Qin, as far as I know, if you want to use the orbit change to achieve landing, you need to solve four difficult problems: de-orbit, transition, re-entry and landing.”
”I would like to ask Professor Qin, which subject are you going to start with?”
Yes, if you want to use the orbit change to achieve landing, then you have to solve these 4 problems!
How to leave the orbit, if it enters the atmosphere too much...
There can be no mistakes in every link.
If something goes wrong, then the cabin will be destroyed!
Hearing Zhou Minggang's words, Qin Luo narrowed his eyes for a moment in thought.
”Let's start with deorbit first.” Qin Luo said with a smile, ”Since we want the astronauts to return safely, we must first leave the orbit.”
”If you can't even realize this step, then saying a thousand things and ten thousand things is just empty talk.”
Newton's discovery of the law of universal gravitation directly opened the door of science. He proved that everything has gravitation and is attracted by regions.
The same is true for tracks.
In space, the space shuttle actually cannot move freely.
Instead, they fly around the ground under the traction of gravity.
Every lap always runs on a fixed track.
To break free from the shackles of gravity, it is unceremoniously difficult to say!
Off track?
Hearing Qin Luo's words, Zhou Minggang's mouth twitched.
This Nima, he really didn't expect that Qin Luo would either not choose, and he chose the most difficult one!
In Zhou Minggang's script, he originally thought that Qin Luo would choose a simpler landing as a breakthrough.
As a result, he never expected that Qin Luo would choose one of the rarest ones.
How long will it take to overcome this subject?
