  4. Technology Readiness Levels • TRL 1 Basic principles observed and reported • TRL 2 Technology concept and/or application formulated • TRL 3 Analytical and experimental critical function and/or characteristic proof-of-concept • TRL 4 Component and/or breadboard validation in laboratory environment • TRL 5 Component and/or breadboard validation in relevant environment • TRL 6 System/subsystem model or prototype demonstration in a relevant environment (ground or space) • TRL 7 System prototype demonstration in a space environment • TRL 8 Actual system completed and “flight qualified” through test and demonstration (ground or space) • TRL 9 Actual system “flight proven” through successful mission operations
