All systems go
Meaning
This phrase indicates that everything is prepared and ready for immediate action or launch.
Origin
The phrase "All systems go" soared into public consciousness with the dawn of the American space race in the mid-20th century. It became a critical confirmation from NASA's mission control, signifying that every component, from the rocket engines to the life support systems, was fully operational and cleared for launch. This final, reassuring call, often heard just before ignition, conveyed a sense of absolute readiness and meticulous preparation, quickly moving from the mission control center into everyday language to describe any situation where everything is perfectly aligned for a successful start.
Examples
- After months of planning, the team confirmed all systems go for the product launch next Tuesday.
- The astronauts reported all systems go just before the final countdown commenced.
