Why Are Rocket Launches Becoming More Frequent?

Rocket launches are becoming more common, and the frequency of these launches has increased in recent years. While there isn't a significant increase in the number of rockets taking off, the publicity surrounding these events has grown significantly. This is partly due to the efforts of companies like SpaceX, which offer cheap and highly publicized launches.

Historical Context

According to Orbital Launch Summary by Year, the annual launch rates from 1965 to 1988 were consistently higher than the rates from 1991 to 2017. In fact, 2018 saw a return to historical levels, with 114 space launches worldwide compared to 91 in 2017. However, in the first half of 2019, there were only 41 launches, which is about average for the last two decades.

The spike in 2018 can be attributed to SpaceX. Their mission to democratize space exploration by offering cheaper and more frequent launches has made these launches more noticeable. The SpaceX website provides detailed information on their launch rates, which are now much more frequent than before. SpaceX's cost-effectiveness is driving other launch entities to lower their prices and increase their visibility. This highlights the principle of supply and demand in action, where cheaper launches lead to more customers and, consequently, more launches.

Market Growth and Technological Advancements

Apart from SpaceX, the growth in the demand for satellite internet, Earth imaging, precision GPS, atmospheric research, and other services is driving the increase in rocket launches. The cost of launching satellites has significantly decreased over the past decades, thanks to less expensive and more reusable rockets. Additionally, microelectronics technology has enabled the construction of smaller and more efficient satellites. These advancements have made satellite launches more accessible, reliable, and profitable than in the 20th century.

Businesses have realized that they can benefit from satellite launches, leading to an increase in the number of private satellite launches. Researchers now find it easier to build satellites for their experiments and explorations. Governments are also recognizing the value of satellites and are now more accessible to many governments, promoting the use of satellite technology in various applications.

Conclusion

While the frequency of rocket launches is increasing, it is not as frequent as it was during the Cold War era. However, the market for rocket launches is growing, and the accessibility and profitability of these launches are higher than ever. As a result, we can expect to see more frequent rocket launches in the coming years, driven by both commercial and scientific interests. The democratization of space exploration, led by companies like SpaceX, is making this possible.
