SpaceX has dramatically changed the space industry through a mix of innovative technology and bold strategic moves. In just a decade, it went from a small startup to becoming the company that represents the entire space industry.
The Falcon 9 rocket is a prime example of SpaceX's impact. Its design for reusability has fundamentally altered the economics of spaceflight. The ability of the Falcon 9's boosters to land and be reused has not just lowered the cost of access to space; it has also increased launch frequency, supporting a wide range of missions from deploying satellites to transporting astronauts to the International Space Station.
The Falcon Heavy, a more powerful rocket, expands SpaceX's capabilities to carry heavier payloads. It combines three Falcon 9 first-stage boosters to increase lift capacity, making it capable of carrying nearly 64 metric tons to low Earth orbit. This makes the Falcon Heavy the most powerful operational rocket available, capable of launching twice the payload of its closest competitor. Since its first launch, which included sending a Tesla Roadster into space, the Falcon Heavy has been chosen for various significant missions, including for the U.S. Department of Defense, NASA, and commercial customers needing to send large satellites into orbit.
The key to the success of both rockets is the reusability of their first-stage boosters. Traditionally, rockets were designed to be used once, with the first-stage booster, the most expensive part of the rocket, falling into the ocean after launch. SpaceX transformed this model by designing the first-stage boosters of the Falcon 9 and Falcon Heavy to land safely back on Earth, where they can be refurbished and flown again.
It's estimated that reusing a Falcon 9 booster can save between 30% to 40% per launch compared to the cost of building a new booster. Given that the manufacturing cost of a Falcon 9 booster is approximately $37 million, the savings per reused booster could range from $11 million to over $14 million. This cost reduction has allowed SpaceX to offer more competitive pricing for launches, which can be significantly lower than those of rockets without reusable components. For example, the cost of launching a Falcon 9 ranges around $62 million, considerably less than the Ariane 5, a partially reusable rocket, which can cost upwards of $165 million per launch.
Moreover, the reusability of SpaceX's rockets has led to an increase in launch frequency. Traditional rockets, which require the construction of a new booster for each launch, face limitations on how quickly they can be produced and prepared for launch. In contrast, SpaceX can rapidly refurbish and relaunch its boosters, leading to a shorter turnaround time between launches.
The Space Shuttle was one of the most famous partially reusable spacecraft, designed to be reused up to 100 times for lower orbit missions. However, the Space Shuttle's operational costs were high, approximately $450 million per launch, partly because its main tank was not reusable.
However, SpaceX's approach to reusability is now extending towards fairings second stages and potentially. These protective covers carry a significant cost of around $6 million each.
