SpaceX’s Starship has been the talk of the space industry for years, with its promised capability of interplanetary travel and lunar missions. However, during its first orbital test flight, the Starship unexpectedly exploded. This event caused significant concern within both the scientific community and the public. As professionals in the space industry, it is essential that we analyze the explosion and its potential causes. In this blog, we’ll explore what led to the Starship’s explosion and what can be learned from it.

The Starship’s first orbital test flight took place on December 8th, 2021. The launch appeared to go smoothly, with the Starship reaching an altitude of around 10 kilometers. According to SpaceX’s CEO, Elon Musk, the issue occurred during the Starship’s “landing flip maneuver,” where it flips onto its side to prepare for a historic self-landing. However, an issue with the Raptor engines led the Starship to come down hard on its side, causing the explosion.

One possible cause of the explosion was related to the Raptor engines. In a tweet, Musk stated that “initial data suggests that the engines performed well, but something significant happened after the start of the landing burn.” The cause of this issue is currently unknown, but some professionals speculate it could be due to a malfunction or damage to the engines during flight.

Another potential cause of the explosion was related to the Starship’s heat shield. The Starship must withstand extreme temperatures during re-entry, and one theory is that the heat shield was damaged, leading to potential structural problems that caused the explosion during the landing maneuver.

Despite the Starship’s unfortunate explosion, there are several takeaways from this event. Firstly, it shows the complexity and difficulty of designing and launching a spacecraft. Spacecraft designs must factor in a myriad of variables that can impact the mission’s success, and even with the best designs, unforeseen events can occur.

Additionally, the decision to test the Starship via unmanned orbital tests before manned missions turned out to be a wise one. Testing unmanned will always be an essential step in the development and testing of future spacecraft, as it significantly reduces the risks involved with human spaceflight.


The SpaceX Starship explosion during its first orbital test flight was undoubtedly an unfortunate event, but as professionals in the industry, it’s essential to learn from these types of accidents. The causes of the explosion are not yet known, but the possibilities include the Raptor engines or damage to the heat shield during re-entry. Regardless of the cause, it serves as a reminder of the complexity involved in designing and launching a spacecraft. Still, the Starship’s failure underscores the importance of thorough testing, continuing research, and an awareness of potential risks to ultimately forge a safer path forward for space exploration.
