Choosing the Final Frontier:

Spaceport Site Selection Is Shaping the Next Phase of Commercial Space

As the commercial space sector scales at an unprecedented pace and the lines between Civil, Military and Commercial space activities blur, a quieter but equally critical race is underway on the ground: the competition to develop viable spaceports.

Once limited to a handful of government-operated launch sites, spaceports are now emerging across the United States and globally, driven by private investment, regional economic ambitions and national security priorities. But according to BRPH’s Derek Nolek and Steve Lloyd, not every location is suited for liftoff, and not every spaceport needs to launch rockets to succeed.

Mission First: Not All Spaceports Are Created Equal

The most important question in spaceport development is deceptively simple: What is it for?

“If you want to support something suborbital—just going up and down—that opens up where you can launch from,” Nolek explained. “But if you want to go to orbit, you need a flight azimuth that avoids overflight of people.”

That distinction fundamentally shapes site selection. Orbital launches require expansive safety corridors, often pushing sites toward remote coastal regions or isolated inland areas. Suborbital operations, by contrast, can operate in a wider range of geographies.

Increasingly, some proposed spaceports are not focused on launch at all. Instead, they are positioning themselves as technology hubs, testing centers or entry points into the space economy: a strategy particularly common among international developments.

“Why you want a spaceport plays directly into location considerations,” Lloyd noted. “Some regions are trying to attract industry or build a workforce, not necessarily launch rockets every day.”

Geography Still Rules

Even as business models diversify, the physics of spaceflight remain fairly consistent.

Engineers begin with trajectory analysis: what orbit is required, what lies downrange and how launch vehicles will behave during ascent and stage separation. For orbital missions, this includes determining where reusable boosters will land. Whether back at the launch site or on other offshore platforms.

“You have to think about recovery from the start,” Nolek said. “If you’re landing downrange, where is your nearest port? How do you get that hardware back?” 

Even expendable launch boosters require a safe drop zone to be identified early in launch licensing. Latitude also plays a role, particularly for payload customers with specific orbital requirements. Satellite missions targeting sun-synchronous or polar orbits, for example, require launch paths that head southward over unpopulated areas.

At the same time, developers must balance these technical constraints with practical realities, including land availability and community acceptance.

Safety Drives Site Selection

Public safety remains the defining constraint in spaceport planning. Until launch vehicle safety factors improve and become similar to commercial aviation, siting will be a significant challenge.  

“You create safety through distance,” Lloyd emphasized. “It’s about keeping trajectories and hazards away from populated areas.”

This has historically led to spaceports being located in sparsely populated regions and along coastal areas. Kennedy Space Center (KSC), Wallops Island, Va., Vandenberg, Calif. and Alaska. But even in low-density areas, community tolerance matters. Noise, environmental impact and perceived risk can influence long-term viability.

Facilities like California’s Mojave Air and Space Port demonstrate how local culture can enable operations. With a long history of aerospace testing and limited commercial air traffic, Mojave offers a controlled environment well suited for engine testing and experimental flight.

Weather, Infrastructure and the Limits of Innovation

Environmental conditions also play a critical role in determining operational reliability.

Low wind speeds, clear skies and stable weather patterns are ideal for launch operations, particularly for vehicles with strict wind and visibility limits. At the same time, environmental sensitivities, ranging from protected ecosystems to local land-use regulations, can complicate development.

Some concepts, such as offshore or sea-based launch platforms, aim to bypass land constraints altogether. But Lloyd cautioned that these approaches introduce significant logistical complexity.

“You’re not just moving a rocket—you’re moving the entire launch pad,” he said. “Cryogenic storage, power, communications, personnel—it all has to go with you.”

Beyond geography and safety, infrastructure often becomes the deciding factor in whether a site can realistically support a spaceport.

Transportation access is critical. “You need highways to move equipment and you absolutely want proximity to an airport,” Nolek said, noting that many payloads and vehicle components are transported by air.

Utilities and community infrastructure are equally important. Power, water, sanitation and housing must scale with the workforce required to support operations, sometimes necessitating entirely new development.

SpaceX’s South Texas site offers a clear example. “They didn’t just build a launch site, they had to build a community around it,” Lloyd noted.

Airports and Spaceports: A Complicated Relationship

Many proposed spaceports aim to leverage existing airports, but integration is not always straightforward.

While shared infrastructure can reduce costs, space operations require controlled airspace and the ability to suspend activity during launches. This can conflict with commercial aviation demands.

“Based on current operational approaches, dual use of, or transitioning a major commercial airport into a spaceport, would be challenging” Lloyd said. “compatible is an issue.” One exception could be the use of exiting commercial airports to support horizontal take-off and landing of spacecraft.

Facilities like Mojave succeed because they operate outside traditional commercial aviation pressures, allowing for greater flexibility and control.

The Next Decade: Reusability and Rapid Cadence

As launch systems evolve, so too will the criteria for site selection.

Reusable vehicles are driving demand for co-located landing and launch facilities, reducing reliance on downrange recovery and improving operational efficiency.

At the same time, increasing launch cadence will place new emphasis on logistics and supply chains.

“When you start talking about hundreds of launches, you can’t rely on ad hoc transportation,” Nolek said. “You’ll need more integrated systems. Pipelines, dedicated transport, things like that.”

Multi-modal transporting capabilities will be required.

With more spaceports entering development, success will depend less on simply having a launch site and more on building a sustainable ecosystem.

Lloyd compares it to retail development: “You need anchor tenants. If you can bring in launch providers, spacecraft manufacturers, and funded missions, and connect them, you’ll have a very successful spaceport.”

Without that alignment, even well-located facilities may struggle to maintain long-term relevance.

As the space industry continues its rapid expansion, spaceport development is emerging as a key enabler and differentiator.

The most successful sites will not just meet technical requirements, but also align mission objectives, infrastructure, regulatory strategy and market demand.

In an industry defined by reaching new frontiers, it turns out that success still depends on choosing the right place to start.
