Project Imua Mission 3 involved the development of a small payload named PrIMEAT ("Project Imua Multiple Experiment Attemtpt Two") that carried an improved sublimation rocket that was deployed at apogee along with video cameras and IMU detectors. This Mission participated in RockSat-X 2017. PrIMEAT was successfully launched into space on a sub-orbital trajectory from NASA Wallops Flight Facility in Virginia in August 13, 2017.

Windward students along with a student from Kauai CC developed an improved micro-thrust rocket (ScubeR). Mission 3’s rocket sub-system included an added heating coil to accelerate sublimation and a re-oriented Hammerhead look-back camera system to photograph the full length of the CarRoLL once ScubeR was released at agogee. The look-back camera was disconnected prior to integration due to WiFi regulations. Mission 3 was conducted in collaboration with HonCC that developed camera monitors and various sensors.
