In September of 2019, SpaceX unveiled the first Starship prototype, the first of several test vehicles that would validate the design of the next-generation spacecraft that would fulfill Musk’s promise of making commercial flights to the Moon and Mars. And while there was a bit of a setback in November of 2019 after the Mk. 1 suffered a structural failure, Musk indicated that the company would be moving forward with other prototypes.
As Musk explained at the time, this would consist of the Mk. 3 prototype conducting an orbital test flight to an altitude of 100 km (62 mi) sometime in 2020. According to recent filings made with the FCC, this test could be happening as early as mid-March and will involve the vehicle launching from the company’s test facility in Boca Chica, Texas, and flying to an altitude of 20 km (12.6 mi) before landing.

SpaeeX and Tesla-founder Elon Musk has made some rather bold promises over the years. In addition to building a fleet of reusable rockets, an Interplanetary Transport System, colonizing Mars, and revolutionizing transportation, he has also made it clear that he hopes to provide worldwide broadband access by deploying a “constellation” of internet-providing satellites.
In November of 2016, SpaceX filed an application with the Federal Communications Commission (FCC) for a license to operate this constellation of non-geostationary satellites (NGS). And earlier this week, the US Senate Committee on Commerce. Science, and Transportation convened a hearing to explore this proposal for next-generation telecommunications services.
The hearing was titled, “Investing in America’s Broadband Infrastructure: Exploring Ways to Reduce Barriers to Deployment”. In the course of things, the committee heard from representatives of government and industry who spoke about the best ways to offer streamlined broadband access (especially in rural areas), the necessary infrastructure, and how to encourage private investment.

Of those the committee heard from, Ms. Patricia Cooper – VP of Satellite Government Affairs for SpaceX – was on hand to underscore the company’s vision. As she stated:
“SpaceX sees substantial demand for high-speed broad band in the United States and worldwide. As the Committee is aware, millions of Americans outside of limited urban areas lack basic, reliable access. Furthermore, even in urban areas, a majority of Americans lacks more than a single fixed broadband provider from which to choose and may seek additional competitive options for high-speed service.”
Cooper also cited recent FCC findings, which indicated that millions of Americans lag behind other developed nations in terms of broadband speed, access, and price competitiveness. Basically, thirty-four million American citizens do not have access to 25 megabits per second (“Mbps”) broadband service while 47% of students in the US lack the connectivity to meet the FCC’s short-term goal of 100 Mbps per 1,000 students and staff.
This is at at a time when global demand for broadband services and internet connectivity continue to grow at an unprecedented rate. According to a report prepared by Cisco in 2016 – titled “White paper: Cisco VNI Forecast and Methodology, 2015-2020” – global Internet Protocol (IP) traffic surpassed the zettabyte threshold. In other words, over 1,000 billion gigabytes of data were exchanged worldwide in a single year!

By 2020, that figure is projected to double, global fixed broadband speeds are expected to nearly double, and the number of devices connected to IP networks is projected to outnumber the global population by a factor of about 3 to 1. To remedy this situation, and bring broadband access in the US up to the average for developed nations, SpaceX plans to launch 4,425 broadband satellites.
These will begin being launched in 2019 aboard the company’s fleet of Falcon 9 rockets. The launches will continue until they have reached full capacity, which is expected to be by 2024. As Cooper outlined it:
“Later this year, SpaceX will begin the process of testing the satellites themselves, launching one prototype before the end of the year and another during the early months of 2018. Following successful demonstration of the technology, SpaceX intends to begin the operational satellite launch campaign in 2019. The remaining satellites in the constellation will be launched in phases through 2024, when the system will reach full capacity with the Ka- and Ku-Band satellites. SpaceX intends to launch the system onboard our Falcon 9 rocket, leveraging significant launch cost savings afforded by the first stage reusability now demonstrated with the vehicle.”
Other details included the operational altitudes of the satellites – ranging from 1,110 to 1,325 km (690 to 823 mi) – as well as the necessary infrastructure on the ground, which would include “ground control facilities, gateway Earth stations, and end-user Earth stations.” SpaceX has also indicated that it plans to deploy an additional 7.500 satellites that will operate at lower altitudes in order to boost broadband capacity in large population centers.
Naturally, there have to be those people who hear words like “satellite constellation” and immediately think “space junk”. Certainly, the deployment of between 4,425 and 11,925 satellites in the coming years will lead to increasing concerns about “orbital clutter”. Especially when other telecommunications providers are seeking to get in on the trend – a good example being Google’s Project Loon.

And while the subject did not come up during the hearing, it will be unavoidable in the coming years and decades. But in the meantime, the idea of bringing internet access to the world – particularly the developing regions of the world where the infrastructure may not otherwise exist – has the potential of being a great social leveler. In the coming decades, it is expected that internet use will reach proportions unheard of a few decades ago.
By 2020 alone, it is estimated that the number of Internet users will reach almost 5 billion – or roughly half the world projected population of 10 billion. This represents an almost threefold increase from the number of internet users in 2010 (1.7 billion) and an almost 14 fold increase since 2000 (360 million). As such, any investment that will help ensure that this growth occurs more equally across geographic and social barriers is certainly a good one.
The committee also heard testimony from Larry Downes, the Project Director of the Georgetown Center for Business and Public Policy, and Brian Hendricks – the head of Technology Policy & Public Affairs for the Americas Region for Nokia. In addition to addressing the current sate of broadband internet in the US, they made multiple recommendations on how the non-geostationary internet satellite industry could be fostered and developed.
