SpaceX faces a critical setback just weeks before its anticipated initial public offering, as the Federal Aviation Administration (FAA) has ordered the company to investigate why its Starship V3 booster failed during a test flight on May 22, 2026. The mishap has effectively grounded further Starship launches until the investigation concludes and the FAA approves SpaceX's corrective actions, potentially narrowing the window for another successful test before the company goes public in mid-June.

What Went Wrong With Starship V3's First Flight?

The upgraded Starship V3 lifted off from SpaceX's Starbase facility in Texas at 5:30 p.m. local time on May 22, marking the first flight of the heavily redesigned rocket system. The 407-foot vehicle, the most powerful rocket ever built, successfully separated its upper stage from the Super Heavy booster and deployed 20 Starlink satellite simulators along with two modified Starlink satellites designed to record footage of the spacecraft's exterior.

However, the booster experienced a critical failure minutes after stage separation. When the booster attempted to perform a sustained burn to return to the launch site, its engines failed to properly re-ignite. The booster then tumbled toward the Gulf of Mexico, where it most likely exploded on impact. Additionally, Starship itself lost one of its six Raptor engines during ascent, forcing SpaceX to abandon one of its testing objectives for the flight.

The FAA's statement confirmed the severity of the incident: "After a thorough assessment of the operation, the FAA has determined the May 22 SpaceX Starship Flight 12 launch resulted in a mishap. The mishap involved the Super Heavy booster as it flew back to the Gulf of America after stage separation. There are no reports of public injury or damage to public property".

Why Does This Matter for SpaceX's IPO Timeline?

The timing of this failure could not be worse for SpaceX's financial ambitions. The company filed for its initial public offering this week, with plans to list on the Nasdaq in mid-June and raise approximately $75 billion. SpaceX intends to use the capital to accelerate Starship development, fund ambitious artificial intelligence (AI) initiatives, and pay down debt associated with Elon Musk's AI company xAI and his social media platform X.

The FAA investigation means SpaceX will have to pause all further Starship test launches until the investigation is completed and approved, diminishing the likelihood of another successful test flight before the IPO window closes. This is particularly significant because industry analysts have emphasized the importance of Starship's performance to investor confidence. Franco Granda, a senior researcher at data firm PitchBook, noted that if Starship's launch goes badly, it could cause investors' excitement for the IPO "to diminish quite dramatically".

How Much Is SpaceX Betting on Starship's Success?

SpaceX's financial disclosures reveal just how critical Starship is to the company's future. In 2025, SpaceX spent over $3 billion on Starship development, and in the first quarter of 2026 alone, the company spent another $930 million. These massive investments are being made while SpaceX's launch business operated at a $662 million loss in the first quarter of 2026, meaning Starship development is consuming the profits from the company's existing operations.

The company's IPO filing explicitly warns investors about the risks: "Any failure or delay in the development of Starship at scale or in achieving the required launch cadence, reusability and capabilities thereafter would delay or limit our ability to execute our growth strategy".

• Starlink Expansion: Starship is expected to carry larger, more capable satellites for SpaceX's Starlink internet service, which is currently the company's only profitable business segment.
• NASA Lunar Missions: The rocket is being developed into a lunar lander for NASA, supporting the agency's plans to return humans to the Moon.
• Mars Ambitions: SpaceX plans to eventually use Starship as a vehicle for crewed missions to Mars, fulfilling Elon Musk's long-stated goal of making humanity multi-planetary.
• Space Data Centers: Musk has recently proposed using Starship to launch data centers into orbit, where they could use solar power to run AI chips, representing a novel application for the rocket.

What Makes Starship V3 Different From Previous Versions?

SpaceX introduced significant upgrades in the third version of Starship, designed to address problems that plagued earlier iterations. The new booster features third-generation Raptor engines that deliver more thrust and have a far simpler design compared to previous versions. These engines have been extensively tested on the ground but have never flown in space before, making their in-flight performance uncertain.

The V3 design also includes refined heat tiles that appear more carefully placed, and it has integrated previously temporary fixes, such as a "hot staging ring" that was bolted onto earlier boosters, directly into the design. Engineer and YouTuber Scott Manley observed that the latest version "looks more like a rocket and less like a bunch of grain silos welded together," reflecting the maturation of the design.

Despite these improvements, the rocket still faces significant challenges. Starship's heat shield has not yet proven durable enough to survive multiple trips through the atmosphere, and the spacecraft has yet to attempt a landing at the pad in Brownsville, Texas. Tim Farrar, president of TMF Associates, which analyzes mobile satellite services, emphasized the complexity of the challenge: "Starship is a multidimensional problem that they haven't actually solved yet".

How to Understand SpaceX's Development Strategy for Starship

• Iterative Testing Approach: SpaceX expects rockets to fail during development, with each test flight designed to gather data and identify problems. The company has conducted 12 Starship test flights to date, with earlier versions experiencing multiple failures before achieving success.
• Rapid Iteration Model: Unlike traditional aerospace development, SpaceX aims to test frequently and learn quickly from failures, accelerating the path to a reliable, reusable system similar to its Falcon 9 rocket.
• Regulatory Oversight: The FAA oversees every step of SpaceX's investigation process and must approve all corrective actions before flights resume, ensuring safety and compliance with federal regulations.
• Reusability as Core Goal: SpaceX's ultimate objective is to make Starship return to the launch pad and be reused almost instantaneously, which would radically lower the cost of space launches and enable the company's long-term vision.

The FAA has ordered SpaceX to perform a thorough investigation into the booster failure, with the agency overseeing every step of the process. This is not the first time the FAA has required such investigations during Starship's development; the agency also ordered SpaceX rival Blue Origin to conduct mishap investigations as it develops its own heavy-lift rocket, New Glenn. Just last week, the FAA cleared New Glenn to fly again, and Blue Origin is expected to attempt its fourth launch in the coming weeks.

The outcome of SpaceX's investigation will determine not only when Starship can fly again, but also how investors perceive the company's readiness for public markets. With the IPO window narrowing and billions of dollars in development costs already sunk into Starship, SpaceX faces mounting pressure to demonstrate that the rocket can eventually deliver on its ambitious promises.
