For more than half a century, space activity has been defined by moments. A rocket launches. A crew travels beyond Earth. A destination is reached. History is made. These achievements, from Apollo to Shuttle to Artemis, have shaped not only the trajectory of space exploration, but the public imagination itself.

The recent Artemis II mission stands firmly in that tradition. It was a remarkable demonstration of technical excellence, coordination, and national resolve, proof that the United States retains the capability to execute complex human spaceflight missions beyond Earth orbit.

But it also highlights a deeper and more consequential truth:
Moments, however historic, do not create permanence.

What is now emerging, in fits and starts, is a structural transition, from exploration as a sequence of singular achievements to space as an operational domain defined by persistence, cadence, and interdependence. This is the threshold to continuous presence.

From Missions to Continuity

The difference between early exploration and sustained presence can be summarized simply:

Projects deliver outcomes. Infrastructure makes those outcomes durable.

NASA’s mission-based exploration is episodic by design. Artemis II, like Apollo before it, was a tightly integrated, bespoke effort calibrated to achieve a specific objective. Success is binary: the mission is completed, or it is not.

Sustained presence requires something fundamentally different. It depends on repeatable operations, logistics networks, transportation layers, supply chains, and systems that endure beyond any single mission. Success is measured not by arrival, but by uptime, reliability, and continuity over time.

The distinction is clearest in logistics. In the mission model, logistics are heroic, meticulously planned for a single event. In a continuous environment, logistics must become routine. Inventory must be managed, not simply delivered. Multiple providers must operate in parallel. Repair, replacement, and upgrade cycles must be embedded into the system.

NASA’s Artemis is an expedition. Sustained presence is the foundation of an economy.

Infrastructure Determines Outcome

If missions capture attention, infrastructure determines outcome.

In a mission-based paradigm such as Artemis II, communications, navigation, power, and coordination are mission-specific, optimized for success within a defined timeframe.

In a continuous operational environment, these functions must become persistent and scalable:

• Communications must evolve into lunar relay networks supporting multiple users
• Navigation requires lunar-specific positioning, navigation, and timing (PNT) systems
• Power must be generated, stored, and distributed across locations
• Operations must incorporate autonomy and interoperability across providers
  
  

Without these foundational layers, every mission remains isolated, forcing the system to reset each time. With them, activity compounds, enabling growth, resilience, and scale.

Recognizing this, NASA Administrator Jared Isaacman, drawing on his experience as a successful entrepreneur, has emphasized the importance of NASA working closely with the commercial sector to deploy these enabling capabilities. Infrastructure at scale will not be built by government alone, but through a coordinated public-private ecosystem delivering persistent services rather than one-off mission support.

The International Space Station provided the first proof that continuous human presence is possible. The Moon represents the next step: transforming a destination into a place of sustained activity.

The Commercial Layer: Real but Fragile

A major driver of this transition is the emergence of the commercial space sector. Yet this shift remains in its early stages. Even today, there is ongoing debate about what truly constitutes “commercial” activity, as many ventures continue to rely heavily on government funding and demand.

This question is not new. During my tenure as Senior Director for Commercial Space Policy at the White House National Space Council, I led an interagency effort that produced the Presidential policy directive NSPD-3: U.S. Commercial Space Policy Guidelines.

For much of the Space Age, the federal government maintained an effective monopoly over space activity. Whether by design or inertia, this dominance constrained the development of a truly market-driven ecosystem.

Only in recent years, driven in large part by the success of SpaceX, has a meaningful shift begun. A new generation of companies now offers capabilities across launch, satellite constellations, in-space servicing, orbital habitats, and even the early promise of lunar resource extraction.

This surge is real. It is also very fragile.

The commercial space sector today faces structural challenges:

• Many firms are under capitalized
• Leadership teams often lack experience scaling aerospace businesses
• Business development remains immature
• Markets are still forming, with inconsistent demand signals
• Legal and regulatory frameworks remain nascent
  
  

As a result, much of the current landscape is characterized by ambition outpacing execution. Even credible firms remain dependent on government contracts that are episodic and subject to shifting priorities.

At the same time, civil and military agencies are on a steep learning curve, adapting from system owners to buyers of services. Procurement models, contracting approaches, and risk tolerances are still evolving.

This creates friction across the ecosystem. Industry struggles to anticipate demand; government struggles to evaluate offerings. Both sides are learning in real time.

To use an apt cliché: We are, in effect, building the aircraft even as we are flying it.

Cadence, Fragility, and Momentum

Cadence is one of the clearest indicators of transition.

Mission-based activity is defined by milestones. Continuous presence is defined by regular, predictable operations. Cadence signals stability, to investors, operators, and policymakers alike.

After decades of observing the factors associated with sustained presence in space, the dynamic can be summarized simply:

P = I × C × M – F
(Presence = Infrastructure × Cadence × Markets – Friction)

Infrastructure enables activity. Cadence normalizes it. Markets sustain it. Friction, financial, institutional, or cultural, determines how fast, or whether, the system takes hold.

Today, the friction remains formidable.

The environment is fragile. Setbacks in launch systems, shifts in policy, or funding gaps can quickly disrupt momentum. Yet resilience is also emerging, as companies iterate, learn from failure, and return stronger.

A Foundation Taking Shape

The expanding base of capable commercial providers, combined with a gradual shift in government toward partnership, signals that something more enduring is beginning to take shape.

Government procurement remains largely oriented toward incumbent contractors, but cracks are beginning to show. Emerging pathways, such as the Defense Innovation Unit, SpaceWERX, Space Systems Command’s Commercial Services Office, and NASA’s CLPS and Tipping Point programs, are creating openings for nontraditional space firms. Their common purpose is clear: to work around the inertia of legacy acquisition systems, albeit with mixed success.

This is the nature of an early-stage ecosystem: progress is cyclical, not linear. Hope is not a strategy, but momentum matters.

The growing cadre of commercial providers, combined with a still painfully slow but real shift in government toward partnership, points to something more durable taking hold. The culture and systems are still forming, but the trajectory seems pointed in the right direction: toward a sustainable, market-based infrastructure beyond Earth.
