The Evolution of SpaceX's Starship: From Rough Prototype to Shiny Spacecraft

🚀Stainless steel was chosen over carbon fiber for the Starship due to its ability to withstand high temperatures and cost effectiveness.

⚙️Early Starship prototypes had rough welds and imperfections, but improvements were made through TIP-TIG welding and the use of robotic welding machines.

🔬Laser welding and planishing techniques were introduced to enhance the strength and aesthetics of the welds.

💪Thinner and stronger single-sheet rings replaced multiple-sheet rings, reducing the amount of welding required.

🌟Achieving a completely smooth finish like a mirror for Starship would require an extensive and time-consuming polishing process.

Why was stainless steel chosen for the Starship instead of carbon fiber?

—Stainless steel was chosen for the Starship because it can withstand high temperatures and is more cost-effective compared to carbon fiber.

What were the challenges with welding the early Starship prototypes?

—The early Starship prototypes had rough welds and imperfections due to the lack of experience of the initial welding team.

What improvements were made to create stronger welds?

—Improvements such as TIP-TIG welding, the use of robotic welding machines, and the introduction of laser welding and planishing techniques were made to create stronger welds.

Why were thinner single-sheet rings used instead of multiple-sheet rings?

—Thinner single-sheet rings were used to reduce the amount of welding required and to prevent the metal from buckling under its own weight.

Will Starship ever have a completely smooth finish like a mirror?

—It is unlikely that Starship will have a completely smooth finish like a mirror, as achieving this would require an extensive and time-consuming polishing process.
