SpaceX achieved a major milestone by deploying the first batch of next-generation Starlink satellites aboard Starship Flight 13 on July 25, but the mission revealed persistent challenges with the Super Heavy booster that threaten the company's reusability goals. The upper stage performed flawlessly, carrying 20 third-generation Starlink V3 satellites to space and completing a controlled splashdown in the Indian Ocean. However, the booster experienced engine restart failures during its planned descent, resulting in a hard splashdown in the Gulf of Mexico that damaged the vehicle (Source 1, 3).

The flight came just over a week after SpaceX scrubbed a launch attempt on July 16 when four of the booster's 33 Raptor engines failed to ignite. Engineers replaced six engines before Friday's launch, which lifted off at 5:51 p.m. EDT from SpaceX's Starbase facility in Texas. While the booster performed well during ascent and initial separation, only 10 of its 13 engines restarted for the descent burn, and just five were firing at splashdown, causing the vehicle to hit the water at higher-than-expected velocity.

Why Does This Matter for Starlink's Future?

The successful deployment of V3 satellites represents a critical step for SpaceX's most profitable business. Starlink generated $11.4 billion of the company's $18.7 billion in 2025 revenue, and the new V3 satellites are designed to deliver roughly ten times the downlink capacity of earlier versions, supporting up to 1 terabit per second of data throughput. SpaceX has stated that a single Starship launch could carry 60 V3 satellites, producing a potential twenty-fold increase in downlink capacity compared to what a Falcon 9 rocket can deploy with 27 V2 satellites.

However, the booster failures underscore a fundamental problem: Starship's economics depend entirely on reusing the Super Heavy booster. If SpaceX must expend the booster on each flight, the cost advantage of Starship's massive payload capacity evaporates. The company's own regulatory filings acknowledge this risk, stating that without a fully reusable Starship, progress on Starlink "would be at a slower pace and higher cost".

What Are the Key Technical Challenges SpaceX Still Faces?

The Government Accountability Office (GAO) released a report on July 25 identifying multiple obstacles to SpaceX's timeline for NASA's Artemis moon missions, which depend on Starship as the lunar lander. The agency highlighted several critical issues:

• Cryogenic Fuel Management: SpaceX's progress in developing technologies to manage and transfer liquid methane and liquid oxygen in space remains a top risk, as the lunar lander will require refueling from multiple tanker vehicles in orbit before heading to the moon.
• Raptor Engine Development: The upgraded Raptor engines powering Starship still require work to address issues identified through testing, as evidenced by Friday's engine restart failures.
• Schedule Delays: SpaceX is more than a year behind its original timeline for key milestones, including the critical design review, long-duration demonstrations, propellant transfer tests, and the uncrewed lunar landing flight test.

The GAO noted that SpaceX officials "anticipate encountering technical challenges in the development of the third version of the Starship vehicle, which SpaceX plans to use for the first Starship orbital test flights". These challenges are not merely engineering setbacks; they directly impact NASA's goal of landing astronauts on the moon's south pole as early as 2028.

How Does This Flight Test SpaceX's Public Market Valuation?

Flight 13 carried particular weight because it was the first Starship launch since SpaceX went public in June 2026 in the largest initial public offering in history, raising approximately $75 billion and valuing the company at $2 trillion. The stock opened at $135 per share on June 12 but has since declined to $116.72 as of July 22, representing a 13.5 percent drop below the IPO price and a 48 percent decline from its peak of $225.64.

For public investors, the distinction between a successful test and a business-ready rocket is crucial. SpaceX spent years developing Starship outside the public market, where explosions and missed targets were treated as learning opportunities. Now, every launch is scrutinized by shareholders expecting the company to demonstrate the operational cadence required to justify its valuation. One successful flight is a data point; monthly launches at scale would constitute a business model.

The booster failure and subsequent stock decline underscore investor concerns about whether SpaceX can transition Starship from an experimental platform to a reliable, reusable launch system. The company's ability to rapidly iterate and fix problems, which served it well as a private company, now faces the pressure of quarterly earnings expectations and stock performance.

What Happened During the Upper Stage Flight?

Unlike the booster, the Starship upper stage performed nearly flawlessly. All six Raptor engines operated smoothly during ascent, and the vehicle successfully deployed the 20 V3 Starlink satellites one at a time from a payload dispenser near the nose cone. Six of the satellites carried cameras specifically designed to inspect the Starship's heat shield tiles and overall condition, providing engineers with real-world data on vehicle health before reentry.

In a critical test for future moon missions, the Starship briefly restarted one of its Raptor engines while coasting in space, demonstrating the in-space engine restart capability required for orbital maneuvering and propellant transfer operations. The upper stage then survived the intense heat of atmospheric reentry, flipped upright, and performed a controlled splashdown in the Indian Ocean approximately one hour and five minutes after launch (Source 1, 3).

Notably, the Starship did not explode upon water impact, as it had during the first V3 flight in May. Instead, it floated, allowing SpaceX to deploy a drone to closely examine the heat shield tiles and assess their condition. The 20 Starlink satellites, traveling on the same suborbital trajectory as the Starship, burned up in the atmosphere roughly 20 minutes after deployment, as the vehicle has not yet achieved Earth orbit (Source 1, 3).

What's Next for SpaceX and NASA's Moon Program?

NASA is pursuing a dual-contractor strategy for lunar landers, with both SpaceX and Blue Origin developing vehicles for the Artemis program. Blue Origin's New Glenn rocket will launch its own lander, which also requires in-space refueling. However, Blue Origin suffered a major setback when its third New Glenn rocket exploded during engine testing, seriously damaging the launch pad. The company hopes to resume test flights by year's end, but few details have been provided.

If SpaceX's Starship lander is not ready to meet NASA's 2028 landing target, the agency may rely on Blue Origin's vehicle instead. In the meantime, NASA is preparing an interim Artemis flight in 2027 with four astronauts in an Orion capsule to test rendezvous and docking procedures in low Earth orbit. During that mission, the crew will dock with a Blue Origin lander and later rendezvous with a modified Starship production model, though they will not enter the Starship.

For SpaceX, the path forward requires not just successful individual flights but a dramatic increase in launch cadence. The company must demonstrate that Starship can fly reliably and repeatedly, with the booster returning safely for reuse, before it can claim to have built the operational system that investors paid $2 trillion to acquire.
