9e Vol : SpaceX ne change RIEN avec son STARSHIP ? - Le Journal de la Starbase #248 - Le JDE

Summary

In this update from the Starbase, SpaceX enthusiasts are given a detailed look at ongoing construction, technical challenges, and key developments in the Starship program. Highlights include the demolition of the Highbay to make room for the construction of a massive new facility, updates to the second launch pad, and challenges faced by Starship prototypes like the S33 and S34 due to fuel system issues. Attention turns to the upcoming S35 flight, where unresolved vibration problems could pose a risk. Despite concerns, rigorous testing offers hope for success, while the channel encourages viewers to stay informed and engaged.

Takeaways

• 😀 SpaceX's Starbase site is bustling with various construction and development activities, including the dismantling of High Bay to make room for a new Gigab facility with 24 stands for prototypes.
• 😀 The second launch pad is under heavy construction, with new deliveries of materials like concrete and a large Y-shaped connector being installed.
• 😀 SpaceX continues its systematic maintenance on the first launch pad, focusing on the inspection of Mechazilla arms and the quick disconnect panels, which take damage from intense heat during launches.
• 😀 The site’s evolving infrastructure includes deliveries of additional material for a new flame diverter and other equipment for the second launch pad.
• 😀 SpaceX is working to overcome technical challenges with the V2 version of the second-stage fuel system, particularly with methane fuel pipe vibrations causing failure and explosions in prior tests.
• 😀 The dismantling of High Bay is a critical step to expand the Starbase facility, clearing space for a Gigab structure to house more prototype stands.
• 😀 SpaceX's efforts to address the explosion risk in its rocket prototypes (e.g., S33 and S34) are ongoing, with a focus on redesigning fuel pipes to reduce harmful vibrations.
• 😀 The S35 prototype, slated for the 9th flight, has raised concerns as it seems to lack significant changes to address vibration-related issues, posing a risk for a repeat of past failures.
• 😀 The development pace at Starbase is incredibly fast, with constant changes in logistics and the need for urgent adjustments, such as the quick replacement of S37 with a newly fabricated nosecone.
• 😀 New infrastructure at the Sanchez site includes a large tubular device that acts as a collector for several circuits, feeding into the new orbital table, signaling significant progress in construction.

Q & A

What are the current ongoing projects at SpaceX's Starbase?

The main ongoing projects include the construction of a second launch pad, the maintenance of the first launch pad, and the dismantling of the High Bay building to make space for the Gigab facility, which will increase SpaceX's production capacity.

What challenges are SpaceX engineers facing with the Starship prototypes?

SpaceX engineers are dealing with challenges related to the vibrations caused by the Raptors' engines, which have affected the fuel system, leading to failures in prototypes like S33 and S34. The company is also working on addressing the issues related to the fuel pipes and their ability to withstand extreme conditions.

What specific issues caused the failures of S33 and S34 prototypes?

The failures of S33 and S34 prototypes were due to vibrations generated by the Raptors, which led to resonance with the fuel pipes. This resulted in cracks or failures in the pipes, causing methane leaks and leading to explosions during flight.

How is SpaceX attempting to solve the fuel system and vibration issues?

SpaceX is exploring several solutions, including reinforcing the fuel pipes with materials resistant to vibrations, modifying their design to avoid resonance, and adding dampeners to absorb the vibrations and prevent failure.

What changes are being made to the Starbase construction site?

The Starbase construction site is undergoing several modifications, including the dismantling of the High Bay to make room for the Gigab facility, which will have 24 stands for prototypes. Additionally, the second launch pad is being expanded, and significant maintenance is happening on the first launch pad.

What is the significance of the Gigab facility being built at Starbase?

The Gigab facility is being built to increase production capacity at Starbase, allowing SpaceX to manufacture more Starship prototypes. The facility will feature 24 stands for prototypes, a significant increase from the current six stands.

What are the concerns regarding the S35 prototype for the upcoming 9th flight?

The S35 prototype has not visibly received the necessary modifications to address vibration issues in the fuel system, which could lead to failures similar to those experienced with S33 and S34. This raises concerns about the safety and success of the upcoming 9th flight.

How is the Starship development pace affecting SpaceX's logistics and production?

The rapid pace of development has led to logistical challenges at SpaceX, as the company has to constantly adjust and optimize its production facilities. The workers face a tough schedule with tight deadlines and reorganization efforts to accommodate new prototypes and engineering changes.

What has been the role of the High Bay building in Starbase's history?

The High Bay building has been a significant part of Starbase since its early days, serving as a critical facility for the construction and storage of Starship prototypes. However, it is now being dismantled to make room for the much larger Gigab facility to support the increased production of Starship prototypes.

What is the status of the S37 prototype, and how does it relate to the S35 and S36?

The S37 prototype was rushed into production after encountering delays with other prototypes. It was quickly assembled to replace the S36, which is expected to be fully assembled soon. The S37's rapid development shows SpaceX's ability to adapt quickly, but concerns about its readiness for flight remain due to unresolved vibration issues.
