SpaceX ABANDONNE la table orbitale de sa STARBASE ! - Le Journal de la Starbase #183 - Le JDE

Summary

This script discusses SpaceX's recent developments, focusing on the FAA's plan for the reorganization of the launch site and the potential construction of an on-site air separation unit to produce necessary gases for rocket fuel. It also covers the upcoming tests for the Starship prototypes B12 and S30, the challenges of the FAA approval process, and speculations about the design of a second launch pad. The video provides insights into the technical differences of the Starship HLS intended for lunar missions, including the absence of a thermal shield and modifications for lunar landing and crew sustenance.

Takeaways

• 🚀 The FAA has published a plan concerning the reorganization of SpaceX's launch site, which was previously discussed in a weekend update.
• 🔄 The sudden reappearance of an old air separation unit at the site is intended to allow SpaceX to produce part of its propellant on-site.
• 🏗️ SpaceX is planning to construct a new factory on its launch site, which raises questions about the necessity and purpose of such a facility.
• 🌐 The air separation unit could help alleviate traffic and reduce delivery influx to the site, potentially lowering costs and improving efficiency.
• 📈 The new configuration of the launch site will allow for more storage of methane, oxygen, and nitrogen to meet the high demand of the prototypes.
• 🛰️ The script discusses the upcoming tests for the Starship prototypes B12 and S30, with the next flight attempt expected at the end of the month or early September.
• 🛠️ SpaceX must undergo a 'wed rest reheursal' test, simulating a launch without igniting the engines, to ensure all systems function correctly.
• 📝 The FAA will review the data from SpaceX's last flight and may require corrective measures for the next launch, including environmental considerations.
• 🌕 The script speculates on the design of the future HLS (Human Landing System) version of the Starship, which will be different from the cargo versions.
• 🛡️ The HLS version will lack a thermal shield and aerodynamic control flaps, as it is designed for space travel only and will not return to Earth.
• 🔧 The HLS will feature a deployable landing gear, a life support system for autonomous living, and an elevator system for heavy equipment deployment on the lunar surface.

Q & A

What is the main topic of the video script discussing?

The main topic of the video script is the inspection of the SpaceX launch site, the FAA's plan for reorganization, and the implications for the production and testing of the Starship prototypes.

What is the FAA's role mentioned in the script?

The FAA (Federal Aviation Administration) is responsible for giving the final approval for SpaceX's operations, including the launch of the Starship prototypes, and is involved in the environmental assessment of the launch site.

What is the significance of the air separation unit mentioned in the script?

The air separation unit is significant because it allows SpaceX to produce some of its propellants, such as liquid nitrogen and oxygen, on-site, which are essential for launches and static fire tests.

Why is the construction of a second launch pad important for SpaceX?

The construction of a second launch pad is important for SpaceX to increase its launch capabilities, potentially reducing the traffic on the main highway serving the site and decreasing the need for deliveries, thus lowering costs and improving efficiency.

What is the 'wed rest reheursal' test mentioned in the script?

The 'wed rest reheursal' test is a final test before a launch where the rocket goes through a full countdown simulation, including fueling the tanks and going through the countdown without actually igniting the engines, to ensure all systems are working correctly.

What is the purpose of the 5-meter high wall planned by the FAA?

The 5-meter high wall is planned to be built along the road to provide a secure boundary for the launch site, allowing trucks to deliver their cargo directly to the wall, which will then be transported to the dedicated reservoir via pipes.

What are the possible configurations for the second launch pad mentioned in the script?

The possible configurations for the second launch pad include two trenches on each side to channel the flames, a single flame deflector closed on one side and open on the other, or a central deflector directing the thrust and flames towards the lagoon, opposite to the launch site direction.

Why is the absence of a thermal shield on the Starship HLS significant?

The absence of a thermal shield on the Starship HLS is significant because it simplifies and lightens the construction, as the vehicle is not designed to return to Earth and will operate solely in space, thus not requiring the thermal protection for re-entry.

What are the main differences between the Starship HLS and the terrestrial Starship?

The main differences include the absence of a thermal shield and aerodynamic control surfaces on the HLS, a different engine compartment with a deployable telescoping landing gear, an independent propulsion system for gentle landing on the Moon, and an internal layout designed to support a crew for an extended period.

What is the importance of the Starship HLS's independent propulsion system?

The independent propulsion system is crucial for the HLS's final braking and landing on the Moon's surface without creating a crater, ensuring the safety of the crew and equipment, and is designed for absolute reliability due to its critical role in human spaceflight.

How does the internal layout of the Starship HLS differ from the cargo Starship?

The internal layout of the Starship HLS is designed to support a crew's life in complete autonomy for several days, with a large airlock for heavy equipment deployment on the lunar surface, an elevator system, and a living area separate from the cargo area.
