ClassX Video Lessons Youtube Channel Primal Space Will the SpaceX Starship fail like the Space Shuttle?
In 1972, the final Apollo mission to the moon was completed, and President Nixon introduced a groundbreaking new spacecraft: the Space Shuttle. This was the first winged spaceship and the world’s first reusable spacecraft, designed to carry astronauts and large satellites into Earth’s orbit. The goal was to make space travel more affordable by reusing the spacecraft. While the Space Shuttle had many successful missions, it didn’t fully deliver on its promises.
Today, SpaceX is working to make space travel cheaper and more efficient. But how is SpaceX’s approach different from the Space Shuttle? How can we be sure that SpaceX’s Big Falcon Rocket (BFR) won’t face the same problems?
The Space Shuttle was supposed to be reusable and cost-effective. NASA estimated that over 14 years, the Shuttle program would cost about $45 billion, with each flight costing $54 million. However, these estimates were way off. The Shuttle needed extensive repairs after each flight, which took much longer than expected. Instead of a quick two-week turnaround, it often took about three months. The engines had to be removed and refurbished, and the toxic propellants used made handling the Shuttle difficult.
One major issue was the heat shield, made up of 35,000 tiles that needed individual inspection after each flight. SpaceX plans to use a material called PICA-X for their heat shield, which can be used many times before needing replacement.
For the BFR to be successful, SpaceX must perfect rocket reusability. The Falcon Heavy, in its reusable mode, can carry a payload similar to the Shuttle’s but at a much lower cost. However, ensuring safety is crucial. The Space Shuttle program faced disasters partly because NASA became less strict about safety in the 1980s, leading to tragic accidents.
SpaceX aims to avoid these mistakes by not rushing to meet deadlines. They have shown they can quickly improve their rockets, as seen with the Falcon 9, which was upgraded with each new version. However, failures are not an option when human lives are involved.
The Space Shuttle’s design and manufacturing involved many companies, increasing costs and complexity. NASA’s requirements often forced the use of outdated technology. In contrast, SpaceX designs and manufactures most of the BFR’s components in-house, ensuring everything works together smoothly.
While the excitement around the BFR is reminiscent of the early Space Shuttle days, SpaceX seems to be on a stronger path. Their track record suggests that the BFR could be a significant advancement in space travel.

The year is 1972, and the final Apollo mission to the moon has just been completed. President Nixon has announced a new American spacecraft: “This is the largest spacecraft ever launched by man, the first winged spaceship, the world’s first reusable spacecraft”—the Space Shuttle. It was designed to carry several astronauts as well as large satellites into Earth’s orbit. This innovative idea for a reusable spacecraft aimed to significantly reduce the cost of reaching orbit. Although the Space Shuttle completed hundreds of successful missions, it did not fully meet its initial promises.
Today, we have SpaceX making another attempt to lower the cost of space travel. But what are they doing differently? How do we know the BFR won’t face the same challenges as the Space Shuttle? In this video, we will compare the BFR to the Space Shuttle and examine what led to the Shuttle’s shortcomings, as well as what SpaceX is doing to prevent the BFR from facing similar issues.
From the outset, the Space Shuttle was intended to be reusable and cost-effective. During its development, NASA estimated that the total cost for the Shuttle’s 14-year lifespan would be around $45 billion, with each flight costing approximately $54 million. Unfortunately, NASA’s original estimates were significantly off, primarily due to the extensive refurbishment required after each flight. The initial plan was for the Shuttle to undergo quick checks between flights, similar to an airliner, with a turnaround time of about two weeks. In reality, it often took around three months. Each of the three RS-25 engines had to be detached and refurbished after every flight, and the toxic propellants used for the RCS thrusters prevented other activities from being conducted on the Shuttle during handling.
One of the most time-consuming aspects of the Shuttle’s refurbishment was the heat shield, with each of the 35,000 tiles needing individual inspection between flights. SpaceX plans to use a material called PICA-X for their heat shield, which is designed to wear away gradually after each flight. SpaceX aims to achieve hundreds of uses from it before a complete replacement is necessary.
For the BFR to succeed in being cost-effective and reusable, SpaceX must master rocket reusability. The Falcon Heavy, in fully reusable mode, can currently carry a similar payload to the Shuttle but at a fraction of the cost. However, even if they achieve rocket reusability, they must do so without compromising safety. One of the significant issues in the Space Shuttle program stemmed from NASA’s changing attitude toward safety, which became more lenient in the 1980s. Due to an ambitious launch schedule, management began to overlook potential safety hazards, leading to two tragic disasters.
With the BFR aiming for its first flight to Mars in 2022, it is crucial that SpaceX does not follow a similar path of cutting corners to meet deadlines. SpaceX has demonstrated a capacity for rapid design changes to their rockets. Andy Lambert of SpaceX noted that no Falcon 9 was ever identical, with upgrades made to each new rocket. This rapid development allowed them to refine the Falcon 9’s propulsive landing technique. However, they have also experienced failures, which will not be acceptable once they start launching humans on the BFR.
Another challenge for the Space Shuttle was its design and manufacturing process, which involved multiple companies across the country. This approach not only increased costs but also added complexity to the Shuttle’s construction. Additionally, NASA imposed certain requirements that often necessitated the use of outdated hardware instead of developing newer, more effective solutions. In contrast, SpaceX can design the BFR from a blank slate, with most components being designed and manufactured in-house, ensuring that every part of the vehicle works together seamlessly.
While the excitement surrounding the BFR may remind some of the early days of the Space Shuttle, it appears that SpaceX is starting off on a stronger foundation. If their track record is any indication, the BFR promises to be an exciting development in space travel.
