For much of the Space Age, spacecraft were designed for a relatively predictable environment. They launched with a defined mission, entered an expected orbit, and carried the fuel, communications, and capabilities needed to perform that mission.

The environment around them is changing.

As space becomes more congested and contested, the ability to simply reach orbit is giving way to another requirement: the ability to adapt once there.

At The Aerospace Corporation, Bryan Hoke describes that emerging capability as Dynamic Space Operations, or DSO. The term encompasses more than maneuver. It is the ability to operate frequently, quickly, and in a sustained manner as the environment changes through competition, crisis, and conflict.

For Hoke, the shift has parallels to aviation. Commercial aircraft are optimized for efficiency, reliability, and predictable operations, while aircraft designed for contested environments prioritize a different set of capabilities, including speed, acceleration, maneuverability, and the ability to refuel. Spacecraft are beginning to face a similar distinction. After decades of operating in a comparatively uncontested domain, the architecture must increasingly support missions that can respond when circumstances change.

And that ability extends across three domains.

PHYSICAL

The physical domain is perhaps the most visible.

Spacecraft need the flexibility to maneuver and adapt. Maintaining that flexibility could require a combination of on-orbit refueling, pre-positioned replacement spacecraft, and responsive launch from Earth. Aerospace is studying how those capabilities can work together to sustain missions and restore infrastructure when disruptions occur.

Those disruptions can take many forms, from debris and solar storms to equipment failures and deliberate actions. Dynamic operations create options for responding as conditions evolve.

Even propulsion becomes a question of mission priorities. Hoke distinguishes between efficient movement and the ability to accelerate quickly when circumstances require it. Dynamic operations demand more than maneuver capacity. They require maneuver flexibility.

ELECTROMAGNETIC

The electromagnetic domain includes communications and the ability to change how information moves when conditions shift. A spacecraft might transition between communications methods or dynamically change frequencies in response to interference or other activity in the environment.

That makes communications infrastructure part of dynamic operations. The spacecraft may remain physically in the same place while changing how it connects, communicates, and continues its mission.

COGNITIVE

Perhaps the least visible part of DSO is the cognitive domain. This is where capability affects behavior.

Hoke points to what he calls a “psychology of scarcity.” When operators know a satellite has a finite supply of fuel, every maneuver consumes part of a resource that cannot currently be replaced. That can discourage training, testing, exercises, and other activities because operators are preserving capability for an uncertain future.

If spacecraft can execute operations without concern for being able to continuously do so in the future, operators gain greater freedom to use their capabilities. At the same time, others have less certainty about how much maneuverability a spacecraft retains. Physical infrastructure begins creating a cognitive effect.

FROM CAPABILITY TO INFRASTRUCTURE

Refueling, servicing, logistics, communications, sensing, autonomy, command and control, and responsive launch each provide a capability. Their greater value emerges when they begin working together, giving operators more ways to respond as missions and conditions evolve.

The transformation is ultimately one of choice. A spacecraft with access to fuel, communications, logistics, and supporting services is less constrained by the resources and assumptions established before launch. Dynamic Space Operations turns infrastructure into options, giving spacecraft and their operators greater freedom to determine what happens next.
