Responsive Launch

The ability to quickly prepare and launch a satellite or spacecraft, often within days or hours, in response to an urgent need.

TECHNICAL DEFINITION

Responsive Launch refers to the capability to rapidly prepare, integrate, and launch space assets (e.g., satellites) on short notice, typically within days or hours, to meet urgent operational requirements, often leveraging small launch vehicles and streamlined processes.

BACKGROUND

Space launch market competition is the manifestation of market forces in the launch service provider business. In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using, regulating or licensing the launch service.
