This second-year effort focused on Virtual Reality/Augmented Reality (VR/AR) engineering applications, now renamed internally as the Mixed-Reality Engineering Toolkit (MRET. The development team had an important and very successful year in FY18 and expanded on the success of the first year. A VR/AR tool was created that can be used for everything from pre-phase-A design concepts and hardware integration, test planning, and execution, to use as a visualization tool for flight-hardware testing. The MRET is able to use concepts created in early design studies (e.g., pre-Phase A) and ingest hardware telemetry streams to create a mixed-reality situational awareness toolkit using AR and VR headsets. This includes overlaying text telemetry on real-life parts hardware in AR, as well as visualizations, such as coloring a part based on temperature, in VR. This included the creation of a limited collaborative environment in VR over Goddard's Goddard Mission Services Evolution Center (GMSEC) bus, and addition of new tools and utilities such as configurable heads-up displays (HUDs), video streaming, integration with MATLAB, and more.
