ATRC Overview
Open infrastructure notice
ATRC (Atmospheric and Terrestrial Resource Collection) describes open, non-patented methods for
acquiring bulk material from planetary surfaces and atmospheres, preparing it for launch, and delivering
it to orbit. These concepts are intentionally published for unrestricted use by space agencies and
commercial operators.
Intellectual property boundary
Downstream orbital accumulation and construction methods described alongside ATRC are likewise presented
as open infrastructure built on ATRC-supplied mass. The SLPA propulsion architecture, including
regenerative thermal cores and associated multi-mode propulsion systems, is protected under active patent
filings and is offered separately under license.
ATRC focuses on the upstream problem of mass availability: how large quantities of material are
sourced, processed into launchable form, and delivered to orbit at low marginal cost. Once bulk mass is
available in orbit, a wide range of logistics, construction, and industrial activities become feasible.
What follows from ATRC
ATRC does not prescribe how material is used once in orbit. Instead, it enables downstream activities
such as:
- Orbital capture and accumulation of bulk mass.
- Construction of depots, shielding, and structural mass.
- Incremental growth of refueling and manufacturing infrastructure.
- Development of high-throughput in-space logistics.
These downstream activities are presented as open, non-proprietary infrastructure intended to
reduce program risk and encourage broad participation.
Relationship to SLPA
As orbital mass accumulates and infrastructure grows, propulsion systems capable of applying repeated
impulse, operating independent of sunlight, and refueling locally become increasingly valuable.
SLPA propulsion systems naturally address this regime but are not required to implement ATRC.
This separation allows ATRC to function as open terrain, while SLPA provides a licensable industrial
capability layered on top of mature infrastructure.
