This modification pointed out that it will allow the Long March 2F carrier rocket to have a larger payload capacity when it is launched. Some Chinese netizens compared this reusable spacecraft with the rocket booster recovery technology of the American civil aerospace company SpaceX. However, although they are both recoverable rockets or spacecraft, there are not small differences between the two. The rocket booster is only an important part of the launch of the spacecraft, and its function is to provide a strong thrust for the launch of the spacecraft. SpaceX's rocket booster recovery technology can realize the reuse of boosters and fairings, which mainly highlights the superiority of rocket materials, and its effect is to save the cost of rocket launches. Chinese netizens claim that the reusable photo color correction services spacecraft made in China are "higher technology than SpaceX." When you go to work, you often find yourself sleepy even though you have slept for eight hours all day long? Have you ever noticed that the guy next to you sleeps very little every day and doesn't take a lunch break at noon, why is he still high all day long? A few days ago (September 4th), the international journal "Science" published a study. The author used mice as an animal model and found that secretion can regulate the ability to love "sleepy" and not easy to love "㬷". Brain neurotransmitters are called "Adenosine" and "Glutamatergic neuron". In fact Adenosine is not something new, it is one of many secretions that exist in the brain. When you are awake, your brain nerves have already started to release substances that promote sleep, and Adenosine is one of them. The concentration of this sleep-promoting substance will continue to increase, and finally it will form a pressure like overwhelming and sleepy, prompting you to take a break or sleep.
