It seems likely that SpaceX’s Starship exploded during a routine test in Texas on June 18, 2025.
Research suggests the explosion occurred around 11 p.m. CT at the Starbase facility in Brownsville, with no injuries reported.
The evidence leans toward a nitrogen COPV failure as the preliminary cause, but investigations are ongoing.
Incident Overview
On June 18, 2025, SpaceX’s Starship Ship 36 experienced a major anomaly, resulting in an explosion during a routine test at the Starbase facility in Brownsville, Texas. The incident happened around 11 p.m. CT while the rocket was on a test stand preparing for its tenth flight test.
Safety and Response
No injuries were reported, and all personnel were safe and accounted for. SpaceX maintained a safety clear area and is working with local officials to secure the site, with no hazards to surrounding communities.
Cause and Implications
Preliminary data suggests the cause may have been a failure of a nitrogen Composite Overwrapped Pressure Vessel (COPV) in the payload bay, a first for this design. This setback could delay future tests, but SpaceX is investigating with the FAA to improve future designs.
On June 18, 2025, SpaceX’s Starship Ship 36 experienced a significant explosion during a routine test at the Starbase facility in Brownsville, Texas, marking another challenge in the development of this ambitious rocket system. This event, occurring around 11 p.m. Central Time (CT), has drawn attention due to its potential impact on SpaceX’s Mars colonization goals and NASA contracts. Below, we provide a detailed examination of the incident, its context, and implications, drawing from recent reports and official statements.
The explosion took place late on Wednesday, June 18, 2025, at approximately 11 p.m. CT, while Starship Ship 36 was on a test stand at SpaceX’s Starbase facility in Cameron County, Texas, on the southwest Gulf Coast. The rocket was preparing for its tenth flight test when it experienced what SpaceX described as a "major anomaly," resulting in a catastrophic failure. Eyewitness accounts and media reports describe a massive fireball and debris, lighting up the night sky and causing significant damage to the test site.
Importantly, no injuries were reported. SpaceX maintained a safety clear area around the site throughout the operation, ensuring all personnel were safe and accounted for. The company issued a statement via an X post, confirming that the Starbase team is actively working to secure the test site and surrounding area in conjunction with local officials. They also asked the public to avoid the area during ongoing safing operations, emphasizing there are no hazards to residents in surrounding communities

Preliminary data, as reported by sources including CBC and USA Today, suggests the explosion may have been caused by a failure of a nitrogen Composite Overwrapped Pressure Vessel (COPV) in the payload bay. This failure occurred below the vessel’s proof pressure, marking the first time such an issue has been identified with this design. The exact cause is still under investigation, and SpaceX is collaborating with the U.S. Federal Aviation Administration (FAA) to determine the root cause and implement necessary corrective actions.
This incident is not isolated, as Starship has faced multiple challenges during its development. A detailed history of recent tests includes:
May 27, 2025: The ninth flight test ended in a "rapid unscheduled disassembly" after 46 minutes, with debris landing in the Indian Ocean.
Late May 2025: The rocket spun out of control halfway through flight, failing to achieve its goals.
Two months prior to June 2025: Exploded in space minutes after lift-off, prompting the FAA to halt air traffic in parts of Florida.
January 2025: Broke up in space, raining debris over Caribbean islands, causing minor damage to a car in Turks and Caicos Islands.
March 2025: Another mid-flight explosion, with fiery debris over Florida.
Successful Tests in 2024: Three tests between June and November 2024 flew halfway around the world and landed safely in the Indian Ocean, demonstrating progress.
The FAA recently closed an investigation into an earlier incident, citing hardware failure in one engine, with SpaceX implementing eight corrective actions. These repeated failures highlight the iterative nature of SpaceX’s development process, where each test provides critical data for improvement.
Starship, standing at 403 feet (123 meters) tall, is propelled by 16.5 million pounds (7.5 million kilograms) of thrust from its 33-engine Super Heavy booster. It can carry 10 times the payload of SpaceX’s Falcon 9 and is constructed using stainless steel and methane, making it fully reusable. The rocket is central to Elon Musk’s vision of colonizing Mars, with a goal to reach the planet by the end of 2026. Additionally, SpaceX has NASA contracts worth $4 billion for the 2027 Artemis III mission, underscoring its importance for lunar exploration.
The explosion is a setback for the Starship program, potentially delaying the tenth flight test and impacting timelines for Mars missions and NASA contracts. However, industry experts and SpaceX supporters view such incidents as part of the rapid iteration process. As noted in replies to SpaceX’s X post, failures are expected when pushing the boundaries of space exploration, and each anomaly provides valuable lessons. Analysts suggest that while the incident is disappointing, SpaceX’s history of learning from failures—such as the crater left by previous tests—indicates resilience and a commitment to eventual success.
The real estate market could also face pressures, as low rates might encourage borrowing but could lead to asset bubbles if not managed carefully. Analysts from ING Bank and Capital Economics suggest another cut in September is likely, with some even predicting a possible return to negative rates. Conversely, EFG analysts believe the SNB may pause unless economic conditions worsen significantly.
This incident comes amidst ongoing global space development efforts. For instance, NASA’s Artemis program relies on Starship for lunar missions, while competitors like Blue Origin and Boeing continue their own rocket development. The explosion underscores the high risks associated with testing cutting-edge space technologies, a challenge faced by all major players in the industry.
