00:00Before watching the video, let me remind you that there is more content on the Hotpot website.

00:05For those who know a little bit about rocket science and technology,

00:08when a rocket is launched into space,

00:10most of the volume and weight of the rocket itself is used to release rocket fuel.

00:15The rocket needs a large-capacity booster to push the spacecraft into the air.

00:21After the fuel is burned, the booster will leave the rocket and fall into the ocean.

00:26But such a rocket launch program is a waste of money,

00:30because the booster cannot be reused, and it takes a lot of time to find it.

00:35Have you ever thought about it?

00:37If one day these boosters land on the ground after they are launched into space,

00:42they will be back in the launch pad every day.

00:44Isn't that perfect?

00:46And today, space history has finally come to an end.

00:49Yes, SpaceX, the first American space exploration company owned by Musk,

00:55has completed this creation today and set a new record in space history.

01:00SpaceX has launched the fifth StarShip,

01:04which is equipped with a very large-capacity booster.

01:07When it fell to the ground at an altitude of 70 kilometers,

01:11SpaceX engineers used the booster's propulsion system to control the speed,

01:17angle, and position of the booster.

01:19Before it landed on the ground, SpaceX used the mechanical arm of a chopstick for the first time,

01:24and successfully clamped the super-heavy booster back into place.

01:28Let's take a look at the footage of this creation.

01:32This morning, the SpaceX StarShip was successfully launched at the Boca Chica Space Station in Texas.

01:38The staff there cheered.

01:41We have liftoff.

02:38Are you kiddning me?

03:08The booster is perfectly landing under a red sun

03:13and writing a chapter in the history of science fiction

03:21If what you just saw wasn't a special explanation

03:24would you think it was a reverse playback of a normal rocket launch?

03:29If that's what you think, then you're right

03:31SpaceX founder Musk once said

03:33The inspiration to use mechanical arms to hold a rocket comes from chopsticks

03:38Its structure is simple and the principle is easy

03:41More importantly, for SpaceX

03:43the rocket can be reused

03:45You can check and replenish the fuel immediately

03:47The landing booster can be connected to another new spacecraft

03:52in a few days or even a few hours

03:55for the next flight

03:58Everyone knows that

04:00Musk has always wanted to immigrate to Mars

04:03Like this time, the design of the new rocket Starship

04:07is a super-large spaceship

04:10It can carry 100 astronauts

04:12instead of the traditional NASA spacecraft

04:15which can only carry 6-7 people

04:17From this comparison

04:20we can see that Starship is much bigger than a normal spacecraft

04:25in order to carry more people

04:28Why do we have to make the booster rocket spin?

04:31Why do we have to hold it by chopsticks and not let it hit the ground?

04:35The reason is very simple

04:37Because if it hits the ground, it will add weight to the rocket

04:42In order to make the rocket lighter

04:44it's better to make it spin
