SpaceX is making steady progress in its testing activities for Starship Flight 5, scheduled to take place in late November at the earliest. This fifth test flight will mark the third of its kind in 2024 and will be the first attempt to catch the Super Heavy booster with the launch tower's catch arms.

As part of its testing activities, SpaceX recently stripped its earliest Starship prototype, Starhopper. This prototype, which flew for the first time in July 2019, played a crucial role in the initial stages of the Starship program. The removal of its outer layers is believed to be a result of damage sustained during Starship's integrated test flight last year.
Meanwhile, SpaceX's latest Starship rocket engine series, the Raptor 3, has undergone testing at its McGregor facility. This simplified design promises improved performance and efficiency. The Raptor 3 engine is a vital component of the Starship program, enabling the spacecraft to achieve its desired orbit and propulsion.
The company conducted eight separate tests of the launch tower's arms, simulating the catch attempt sequence. This critical aspect of the Starship test profile is being fine-tuned to ensure a successful catch. The tower arms are essential for Starship's rapid reusability, allowing the booster to be refurbished at the pad and quickly stacked with a new ship for relaunch.
A six-engine static fire test was conducted on the Flight 6 Starship second stage, marking one of the final tests before launch. This test demonstrated the spacecraft's propulsion capabilities and paved the way for future launches.
Innovative Catch System
The tower catch is crucial for Starship's rapid reusability. SpaceX aims to refurbish the booster at the pad and quickly stack a ship on top for relaunch. This innovative system has the potential to significantly reduce launch costs and increase the frequency of space missions.
Upgraded Heat Shield
The ship's heat shield has been completely upgraded with thousands of tiles, ensuring improved protection during reentry. This upgrade addresses concerns raised during previous test flights and enhances the spacecraft's overall safety. Particular focus of this upgrade were the gap between the flap joints which have been shielded with better fitting tiles as well as thicker sheet metal to endure the immense heat faced during the re-entry phase.
FAA Approval Awaited
SpaceX awaits FAA approval, expected by late November, before proceeding with Starship Flight 5. The company has been working closely with regulatory authorities to ensure compliance with safety standards. The FAA has been scrutinizing SpaceX's Starship program, citing concerns over safety and environmental impact. In June, the FAA delayed the approval process for Starship Flight 5, prompting SpaceX CEO Elon Musk to express frustration on social media.
Musk accused the FAA of being overly bureaucratic and slowing down innovation. The FAA responded, stating that its primary concern was ensuring public safety. The FAA's environmental assessment of the Starship program raised concerns over potential impacts on local wildlife and ecosystems. SpaceX's Boca Chica launch site, located near a sensitive ecosystem, has sparked worries among environmental groups.
The FAA has also expressed concerns over the safety of SpaceX's launch operations. In February, the agency issued a warning to SpaceX regarding its failure to comply with safety regulations during a Starship test flight. SpaceX has maintained that it is committed to safety and environmental responsibility. The company has implemented measures to mitigate potential environmental impacts and ensure compliance with safety regulations.
Starship Flight 5 Preparation
Despite the regulatory hurdles, SpaceX continues to prepare for Starship Flight 5. The company has:
- Conducted Raptor engine tests
- Upgraded GSE and Tower Catch Arms
- Tested the launch tower's arms also known as ‘Mechazilla’.
- Conducted a static fire test of the second-stage Starship.
The success of Starship Flight 5 will have significant implications for SpaceX's future plans. With its rapid reusability capabilities, Starship is poised to become a game-changer for space exploration. SpaceX's long-term goals include establishing a permanent human presence on Mars and beyond and the success of Starship is paramount for that to happen.

I hate that bureaucracy has such a chokehold on the smart people. I k own there must be some reg’s, bribes, etc. Let’s get on with it! Kowtow, grease some corrupt government palms, and launch.
