Moore’s Law, Wright’s Law, and their Relevance to the Space Economy

In the dynamic realm of technology and manufacturing, two principles have played pivotal roles: Moore’s Law and Wright’s Law. Born out of observations in microchip development and aircraft production, these laws now stand as influential factors in a range of industries. One field where their impact is particularly significant is the growing space economy. As we continue to explore the final frontier and democratize its access, these laws offer important insights into how the sector is evolving and growing.

Understanding Moore’s Law

Moore’s Law, named after Gordon E. Moore, the co-founder of Intel, originally described a trend in the realm of microprocessors. Moore observed that the number of transistors that could be fitted on a microchip seemed to double approximately every two years, effectively doubling the processing power of these devices. Furthermore, this increase in capabilities coincided with a halving in cost, a phenomenon often associated with the “democratization” of technology.

While Moore’s Law has sometimes been critiqued for its potential inaccuracy or over-optimism, it has nonetheless generally held true in the decades since Moore first articulated it in 1965. Moreover, the principle of rapid, exponential growth in technological capabilities has been applied far beyond microprocessors, particularly as we enter an era defined by digitization and connectivity.

Understanding Wright’s Law

Wright’s Law, named after Theodore P. Wright, who observed a specific production phenomenon within the aircraft industry in the 1930s. He noted that for every cumulative doubling of units produced, the costs fall by a consistent percentage. Put simply, as we manufacture more of something, we get better and more efficient at it, reducing the cost per unit. This law, often termed the “learning curve” effect, has been observed in various sectors of manufacturing and production.

Applicability to the Space Economy

Moore’s Law in Space

The continual advance in computational power and digital technology described by Moore’s Law has significantly affected space technology. Today’s spacecraft are equipped with microprocessors that are significantly more powerful and much smaller than their predecessors. This has led to more capable spacecraft. Furthermore, these advancements have fostered a trend toward miniaturization in space technology, resulting in the development of small satellites, like CubeSats. These small satellites can be launched in large numbers at a comparatively low cost, democratizing access to space.

Moreover, the increase in computational power has also facilitated improvements in communication, navigation, and data processing capabilities of spacecraft. This has allowed for more complex and sophisticated space missions and has also led to an increased commercial utilization of space-based assets, such as communication satellites and Earth observation platforms.

Wright’s Law in Space

The principles of Wright’s Law are observable in the domain of spacecraft manufacturing and launch services. With the production of more rockets and spacecraft, efficiencies in production, operation, and recovery are discovered and implemented, leading to cost reductions.

SpaceX has become synonymous with innovation and cost reduction in space launches, exemplifying the principles of Wright’s Law. Their focus on developing reusable rockets stands as a revolutionary step, drastically reducing the cost per launch.

SpaceX’s Falcon 9 and Falcon Heavy launch vehicles are designed to return to the launch site after delivering their payload to space, a contrast to the traditional use-once-and-discard approach. These boosters land vertically, using the same engines that propelled them into space. This feat of engineering not only exemplifies a technological leap but also represents a significant cost-saving measure. Every successful recovery and reuse of a Falcon booster reduces the cost of the next flight.

Wright’s Law is in full effect here. As SpaceX has iterated the design, construction, launch, recovery, and refurbishment processes of these rockets, they have identified efficiencies and cost-saving measures. As the number of successful recoveries and reuses grows, so does SpaceX’s proficiency, effectively reducing costs.

Future Possibilities

Moore’s Law and Wright’s Law serve as valuable models for understanding trends in the space industry. These principles suggest a powerful positive feedback loop: as technology improves and production becomes more efficient, costs drop. This then opens up new opportunities, leading to more production, further technological advancement, and an ever-expanding horizon for the human exploration and utilization of space.
