• COPV Failure: Composite Overwrapped Pressure Vessel failure, a type of component failure.
• Polar Orbit: An orbit that passes over or nearly over both poles of the planet.
• Low Earth Orbit (LEO): An orbit within a few hundred kilometers of Earth's surface.
• Kickstage: A component of the Electron rocket used for precise orbital insertion of payloads.
• Fairing Reuse: Rocket Lab's concept for reusing the payload fairings of the Neutron rocket by keeping them attached to the booster.

Rocket Lab Electron Launch Preview and Context

Tim Dodd, the Everyday Astronaut, is hosting a live stream to cover a Rocket Lab Electron launch, marking his return to covering Rocket Lab after a period of travel and scheduling conflicts. He highlights that this is Rocket Lab's 19th launch of the year, a record for the company, and the 77th Electron mission overall. This launch also contributes to the 300th orbital launch attempt of the year across the industry, indicating a significant increase in launch cadence compared to previous years.

The launch is taking place from Rocket Lab Launch Complex 1 on the Mahia Peninsula in New Zealand, targeting a polar orbit. Due to the small size and remote launch location of Electron, visibility for local residents is limited.

Rocket Lab's Future: Neutron Rocket and Archimedes Engine

The discussion touches upon Rocket Lab's development of the Neutron rocket, a larger, reusable vehicle designed to compete with larger launch providers. A notable feature of Neutron is its proposed fairing reuse system, where the fairings remain attached to the booster and are recovered with it. This concept is highlighted as innovative, though it adds dry mass to the booster.

The Archimedes engine, being developed for Neutron, is also discussed. It's described as a "beast" with nearly 30 times the thrust of Electron's Rutherford engines. Rocket Lab is actively seeking talent for its Archimedes engine test complex. The development of Archimedes involves a shift from Electron's electric pump-fed system to a more traditional turbopump system, which requires different expertise.

The Unique Rutherford Engine

The Rutherford engine is explained as a key innovation for Rocket Lab. Its special features include:

• 3D Printing: It was one of the first fully 3D-printed main booster engines, made possible by the smaller scale of the Electron rocket.
• Electric Pump-fed System: Instead of complex gas generators or turbo pumps, Rutherford engines use electric motors powered by high-voltage lithium-ion batteries to drive the pumps for liquid oxygen (LOX) and RP-1 (kerosene). This was a novel approach for orbital rockets, leveraging advancements in motor and battery technology.
• Carbon Composite Structure: Electron was the first carbon rocket to go orbital, utilizing carbon composite materials for its tanks and structures, contributing to its lightweight design.
• Battery Jettison: A clever design element is the jettisoning of batteries on the second stage after they are no longer needed. This addresses the lower energy density of batteries compared to propellants and the fact that batteries do not decrease in mass as they are used, unlike propellant.

Mission Details: Neonat 1A for KAIST

Today's mission is deploying the Neonat 1A satellite for the Korea Advanced Institute of Science and Technology (KAIST). This satellite is part of KAIST's planned constellation for near real-time imagery of the Korean Peninsula. Neonat 1A will serve as a communication link between the first satellite launched last year and future satellites in the constellation. The constellation aims to provide multi-daily imaging of the Korean Peninsula, with AI used to combine data for tracking natural disasters and responding to national security events. The satellite is heading to a 540 km low Earth orbit with a 97.4-degree inclination.

Launch Countdown and Hold

The launch countdown proceeds with standard checks and polls. However, a hold is called at T-minus 8 minutes and 7 seconds due to a "groundside issue with the umbilicals or something." Despite efforts to recycle the count and target the end of the launch window, the team is unable to complete the necessary steps in time. Mission control announces a scrub for the day, citing the limited time remaining in the window. The broadcast ends with the promise of future launch attempts.

Tim Dodd's Personal Updates and Music Sneak Peek

Tim Dodd shares updates on his upcoming album, "Direct to Orbital," which is expected to be released by the end of the year or early January. He previews two songs from the album: a new version of "Cryo" (now titled "Cryogenic") and "Liquid Cargo" (formerly "Slow Orbit"). He emphasizes the use of real instruments and professional mixing and mastering for this album, aiming for a significant improvement over his previous work. He also mentions that he will be performing live at the Astro Awards in Austin, Texas, on January 17th and 18th, 2025.

He also confirms that he has completed a tour of another rocket factory with a different CEO, which is currently in the editing process and expected to be released soon.

Discussion on Data Centers in Space

A brief discussion touches on the concept of data centers in space. While acknowledging the thermal challenges, Tim suggests that the cost and land acquisition associated with terrestrial data centers might make space-based solutions economically viable, especially with the abundant solar power available in orbit.

Other Topics Discussed

• SpaceX Going Public: Tim expresses hope that SpaceX will not go public as a whole company, but would be open to a Starlink IPO.
• SpaceX COPV Failure: He mentions a recent COPV failure on a SpaceX booster, noting the lack of public information and expressing concern about repeated failures.
• OceanGate Titan Submersible: The structural integrity of carbon fiber in extreme environments is discussed, with Tim differentiating the stresses of deep-sea submersibles from those experienced by rockets.
• Electron Reuse: Tim believes Rocket Lab is prioritizing Neutron development, and while Electron reuse was considered, the margins were likely too small to be a significant focus.
• Future Launches: Tim anticipates covering the next Starship V3 flight or Artemis 2 as his next major live stream events.

Conclusion

The Rocket Lab Electron launch was scrubbed due to a groundside issue, preventing it from launching within its window. Despite the scrub, the stream provided insights into Rocket Lab's current operations, the unique technology behind the Rutherford engine, and their ambitious future plans with the Neutron rocket and Archimedes engine. Tim Dodd also shared personal updates on his music and upcoming events, highlighting the continued growth and excitement within the space industry.
