Engine overview
Nova was designed, built, and tested under SRT-5 as an improvement over Icarus II. Its changes included a revised injector housing, standardized aluminum plumbing, an upgraded sensor suite, an additive-mixed fuel grain, improved regression behavior, and a thrust profile optimized for the Theseus vehicle.
