Musk has transformed numerous industries, from revolutionizing payments with PayPal to reshaping the automobile industry with Tesla, and pushing forward sustainable energy with Solar City. However, few would have predicted that someone without a formal background in aerospace engineering would make significant inroads in rocket technology. Rockets are among the most complex machines ever engineered. The saying "it's not rocket science" is used to describe tasks that aren't particularly difficult for good reason. Interestingly, the most challenging part of a rocket to engineer is its engines. Yet, Musk is achieving remarkable progress in redefining how rocket engines are developed and manufactured, showing that with enough innovation and determination, even the most formidable technological challenges can be overcome. Recently, he revealed the most advanced engine SpaceX has ever developed, along with its groundbreaking features that made headlines. We will dive into the details of this engine in this video. Before we go any further, please make sure to subscribe to our channel for future updates about the Starship and SpaceX's other groundbreaking achievements.

SpaceX started the development of the Raptor engine in the early 2010s, with the intent to replace the Merlin engines used in their Falcon rockets. The Merlin engines, although highly successful, were limited in their capacity to support Musk’s vision of interplanetary travel. The Raptor was conceived to be a more powerful and efficient engine, utilizing full-flow staged combustion technology—a first for an operational rocket engine in the United States, allowing both the oxidizer and the fuel to be pre-burned and used to drive the engine's turbines before combustion in the thrust chamber. This design significantly improves the engine's efficiency and power.
The first prototype of the Raptor engine was tested in 2016. Over the years, the Raptor has undergone various modifications and upgrades. The specifications of these engines have evolved dramatically, from the initial test versions producing around 100,000 pounds of thrust to the more recent Raptor 2 versions, which have achieved thrust levels of approximately 230 tons.
The most recent announcement on Twitter by Musk regarding the future specifications of the Raptor engine highlighted that the engine’s thrust capacity is projected to exceed 700,000 lb.

Historically, some of the most powerful rocket engines, such as the Saturn 5's F1 and Russia's RD-180, have set remarkable benchmarks in the field of rocketry. The F1 engine, which powered the mighty Saturn 5, still holds the record for the highest thrust ever produced by a single combustion chamber, delivering about 1.5 million pounds of thrust. This immense power enabled the Apollo missions to send astronauts to the Moon, making it a legendary piece of engineering.
On the other hand, the RD-180 which is used primarily on the Atlas 5 rocket, is renowned for its efficient use of staged combustion technology.
Despite these historical achievements, these engines were designed with technologies and materials available many decades ago, under conditions that are vastly different from those faced by engineers today.
