Clarifications and Definitions

Precisions on technical terms, methodologies, and interpretation limits of the information presented in our propulsion systems analysis.

Terminology

"Green" Propulsion

In this context, refers to propellants whose production, use, and disposal have a reduced environmental impact compared to traditional hypergolic propellants. This does not imply total carbon neutrality.

Scope

Advertised Efficiency

Specific impulse (Isp) or thrust figures are theoretical or test bench values. Actual mission performance may vary based on space conditions and flight profiles.

Timescale

Technological Maturity

Mentions of "in development" or "emerging" refer to the technology readiness level (TRL) at the time of writing. Deployment schedules are subject to revision.
