The Hard Part of Commercial Space Isn't the Rocket

For two decades, the story of commercial space was a story about cost. Bring launch prices down far enough, the logic went, and a market would appear on its own. That part largely worked. Launch is cheaper and more frequent than almost anyone forecast, and a generation of companies now builds on top of it. The harder transition, the one we are living through now, has very little to do with propulsion. It is the shift from government as the owner and operator of space activity to government as one customer among several. That shift is not an engineering problem. It is a problem of incentives, institutions, and trust, and it is far less solved than the launch curve suggests.

The numbers explain why everyone is suddenly paying attention. A 2024 World Economic Forum and McKinsey study projects the space economy will grow from $630 billion in 2023 to $1.8 trillion by 2035, averaging a growth rate of 9% per annum.¹ The report's authors are careful about where that value actually comes from. As they put it, the headline moments are not the substance: routine rocket launches and satellite data services are, in fact, the product of decades of behind-the-scenes innovation. That sentence is the whole point. The value is in the unglamorous connective work, not the launch.

I have spent my career on the connective work. I have built a national astronaut program from a blank sheet, worked on the commercial side of human spaceflight, designed astronaut selection and training systems, and built aviation training ecosystems that feed into them. Across all of it, I have spent a great deal of time in rooms where governments decide whether to commit public money and political capital to space. The pattern I keep seeing is the same. The technology is rarely the thing that stalls a program. The thing that stalls a program is that the people who must say yes cannot see how to justify the decision inside their own institution.

The customer is changing faster than the buyer

The clearest sign of the transition is the appearance of commercial human spaceflight: private destinations in orbit, privately run missions, services sold to governments rather than built by them. NASA has been explicit that this is the destination. The agency now describes a future in which it becomes one of many customers in low Earth orbit,² and US legislation frames the goal in the same language, calling for an ecosystem in which the agency is one of many customers rather than the owner.³ The supply side has moved quickly to meet that vision. The demand side has not, and this is where most of the friction lives.

A government agency that has spent decades owning its hardware does not become a smart commercial buyer overnight. Procurement rules were written for cost-plus contracts and government-owned assets, not for buying a seat or a service from a private operator. The people inside the agency are measured on control and risk avoidance, not on speed or commercial outcome. I have watched genuinely good proposals stall not because anyone doubted the engineering, but because no official in the chain could work out how to carry the decision through their own approval process and still be safe if something went wrong.

When a minister is asked to fund a commercial flight rather than a national program, the real question is rarely technical. It is what happens to them, to their agency, and to their country's standing if they sign. A government that builds its own capability can point to jobs, institutions, and sovereign control. A government that buys a service has to explain what it got for the money in terms its own public and its own treasury will accept. Until that question has a good answer, the contract does not move, regardless of how good the offering is.

This is the core misread I see from commercial space companies. They sell capability. Governments buy justification.

What building a national program actually teaches you

The thing you learn building a national astronaut program from nothing is that the flight is the smallest part of it. The selection system, the training pipeline, the medical and operational standards, the international agreements, the domestic political narrative, the management of public expectation: all of that has to exist before a single candidate is chosen, and most of it has nothing to do with hardware. A government does not start a human spaceflight program because it wants one astronaut in orbit. It starts one because it wants the institutional capability, the national visibility, and the seat at a table it was previously excluded from.

That experience reshapes how you read a commercial offer. When a provider proposes a turnkey mission, a government's instinct is not relief that the hard parts are handled. The instinct is unease that the hard parts, the parts that build lasting national capability, are being handled by someone else and will leave when the contract ends. A flight delivers a moment. A program delivers a capability that outlives the people who approved it. The transition to commercial space keeps offering governments the moment and assuming they wanted it more than the capability. Often they want the opposite.

This is also where the aviation-to-space crossover matters more than people expect. The disciplines that make commercial aviation safe and routine, the training systems, the human-factors work, the certification culture, the operational standards built up over decades, are precisely the disciplines a maturing space sector now has to absorb. Aviation already made the journey from a dangerous frontier flown by a small elite to a safe, regulated, commercially routine system. Building pilot training ecosystems teaches you that safety culture and operational discipline are not paperwork layered on top of capability. They are the capability. A space program that imports flight hardware but not that culture is building on sand, and sovereign customers, especially those with mature aviation sectors, can sense the difference quickly.

Relevance, presence, belonging

There is a tendency in the commercial sector to treat national interest as an obstacle, a layer of politics getting in the way of an efficient transaction. That view costs deals. For a sovereign customer, the program is rarely about the mission alone. It is about three things, and they are worth naming precisely, because almost every government decision in this domain reduces to them.

Relevance is the first. A country wants to matter in the conversations that shape the sector, to be in the room when standards, partnerships, and rules are set rather than inheriting them after the fact. Presence is the second. Relevance without visible activity is just rhetoric, so a government needs real programs, real people, and real capability that prove it is a participant rather than a spectator. Belonging is the third and the hardest to buy. It is a place inside the partnerships, institutions, and supply chains where long-term influence actually accumulates, the difference between attending the ecosystem and being a member of it.

This framework is no longer the preserve of wealthy spacefaring nations, which is exactly why the politics intensify. The WEF now argues that satellites have become the invisible backbone of development, from connectivity and navigation to climate monitoring and disaster response, and that for emerging economies space is no longer a distant frontier, but the next layer of global infrastructure.⁴ When a capability becomes national infrastructure, relevance, presence, and belonging stop being soft considerations and become the actual terms of the deal.

A country buying into commercial space is buying its position on all three for the next forty years. This is where commercial offers most often fail. An offer can be technically excellent and still lose if it delivers a service while ignoring relevance, presence, and belonging, because it leaves the minister with nothing to defend internally. In my experience the proposal that wins is the one that lets that minister stand in front of their own government and explain, in terms that survive a change of administration, why the country is now more relevant, more present, and more firmly inside the structures that count. Capability is the easy part of that sentence. The last three words are the hard part.

Three problems that have to be solved at once

The transition fails when its three hard problems are treated separately. I have learned to look at all three at the same time, because they fail together.

The first is architectural. Commercial programs still have to be designed as complete systems, from concept through to operation, with the training, infrastructure, and research workstreams integrated into one coherent plan. The commercial framing does not remove this discipline. It often hides it, because the assumption is that the provider handles everything. The provider handles their part. Someone still has to architect the whole, and in a national program that someone usually sits on the government side, often without the experience to do it. This is the single most common gap I am asked to fill: not building the rocket, but building the structure the rocket sits inside.

The second is institutional alignment, and even the agencies running this transition treat it as a first-order task rather than a formality. NASA has described its own roadmap as the product of consultation with industry, academia, and international partners, and frames the entire effort around maintaining what it calls an unbroken, continuous heartbeat of humans in orbit through the handover.⁵ If the organization with the most experience in human spaceflight treats stakeholder alignment as central, a new commercial entrant cannot treat it as a slide at the back of the deck. Alignment is not a kickoff meeting. It is a structure that holds when something goes wrong, because something always does. The programs I have seen survive setbacks were the ones where every major stakeholder had a reason to keep supporting the program even on its worst week.

The third is compliance and trust. Commercial human spaceflight is moving faster than the regulatory frameworks meant to govern it. ESA ECSS, EASA, ISO, and NASA standards were largely built around government ownership and a slow, deliberate verification culture. Commercial operators move at a different tempo. The agencies themselves now say the commercial model must deliver reliable and safe services at a lower cost,⁶ which is a polite way of stating a genuine tension: lower cost and faster cadence pulling against a verification culture built to be slow on purpose. Bridging that gap, building documentation chains, verification, and traceability that satisfy a sovereign reviewer without strangling commercial speed, is one of the least glamorous and most decisive challenges of the whole transition. The programs that earn institutional trust early are the ones that survive. The ones that treat compliance as paperwork to be handled later tend not to.

What the next decade actually requires

The romantic version of commercial space is about access: more launches, more destinations, more people flying. The real transition is quieter and more institutional. It is about building the connective tissue between an industry that now moves at commercial speed and a set of public institutions that still carry the weight of national interest, public money, and political risk.

That connective tissue is mostly human. It is the work of translating a commercial capability into a sovereign justification, of designing programs that earn a country relevance, presence, and belonging rather than just delivering it a flight, of sequencing political, regulatory, and industrial timelines so they reinforce rather than collide. It is the work of bringing aviation's hard-won safety and training culture into a sector that still sometimes treats it as optional. None of this shows up in a launch manifest. All of it determines whether the $1.8 trillion economy actually arrives or simply remains a sequence of impressive demonstrations.

I have spent enough time on both the government and the commercial side of this to be convinced the bottleneck is not technology and has not been for years. The bottleneck is the human architecture: who decides, who is protected, who can justify the decision, who carries the risk, and who is still standing behind the program when it hits trouble. Get that right and the engineering follows. Get it wrong and the best hardware in the world sits unsold.

The rocket was the easy part. The hard part is everyone who has to agree on what to do with it.
