Movie climbing SpaceX's rocket launch pad with Elon Musk's guide



Everyday Astronaut , a YouTube channel that disseminates space-related information, has released a movie with SpaceX founder Elon Musk climbing the rocket launch pad for the company's fully reusable super-large rocket Starship .

Everyday Astronaut reporter Tim Dodd has arrived at SpaceX Starbase , a SpaceX rocket manufacturing and launch facility located approximately 32km east of Brownsville, Texas, USA.



What was taken by Mr. Musk ...



A launch building with a huge robot arm, called '

Stage Zero ', used for 'rocket launch' and 'rocket landing'. The two arms on the Stage Zero are used to hold the rocket at launch and to catch it as it lands on the ground. Looking up at Stage Zero, Mr. Musk said with excitement, 'It's pretty difficult not to get excited about this. Hmm, how crazy this is!'



In addition, Mr. Musk tweeted about this Stage Zero in the past, 'Stage Zero, which is everything necessary for launching and capturing a rocket, is at least as difficult as developing a rocket booster or a spacecraft.'




The booster held by the arm is the following silver cylindrical object. This booster is about 9 meters in diameter and weighs about 250 tons.



It seems that there are metal fittings for hanging the whole in the red frame part at the top of the booster.



Stage Zero has an overwhelming presence. At the time of writing the article, the probability of catching a rocket with a robot arm is unknown, and SpaceX engineers only commented that it was 'above 0'. However, theoretically, when the rocket returns to the ground, it should be possible to slow down and enter between the arms, close the arm and catch the rocket.



You can see how the Stage Zero robot arm actually holds the rocket by looking at the pictures below. It seems that the arm is hooked on the unevenness at the tip of Super Heavy (black), which is the first booster of the reusable rocket Starship.

Then a line going into Stage Zero.



Get in the elevator ...



I will climb up earnestly.



Reach the top that can be reached by elevator.



There was a magnificent view there.




According to a SpaceX engineer, 'Stage Zero is 143 meters high, so it's probably about 138 meters above the ground.' On the other hand, Mr. Musk gives a word like a businessman, 'I may be able to sell the zip line that slides down from here.'



Mr. Musk is excited to take a picture of the scenery from Stage Zero.



In the video from the ground, the size of the first stage booster (black) and the second stage booster (silver) of Stage Zero and Starship seemed to be the same, but the launch building is quite high when viewed from the top of Stage Zero. I understand this.



I can't see the bottom even if I look directly underneath.



'The key to

making humans active across multiple planets is clearly a reusable rocket. Like an aircraft, being able to recycle a rocket completely and quickly. It is important, but it is very difficult to achieve full reusability. The strength of the Earth's gravity field and the density of the atmosphere are obstacles to rocket reusability, but another, such as Mars. This obstacle is lessened on planets, 'he said, arguing that by realizing a reusable rocket on Earth, where the most environmental conditions are difficult, humans can be closer to beings that live across multiple planets. doing.



Mr. Musk cites 'when Comet Shoemaker-Levy 9 collides with Jupiter' as an example of the need for humankind to operate across multiple planets. Comet Shoemaker-Levy 9 said that he had made a hole in Jupiter about the size of the Earth, saying, 'If something similar happens on Earth, humanity will be'game over'as it is. I will do it, 'Mr. Musk said. 'There is always a danger of human extinction,' Musk said, saying that humans need to evolve their civilization to be able to live on multiple planets.

In addition, Everyday Astronaut is planning to release the situation when covering SpaceX Starbase in another movie, and it seems that the video will touch on the rocket engine being developed by SpaceX such as Raptor 2 and Merlin .
