Depending on the project, that may include defining requirements, performing analysis, designing components, creating drawings, working with vendors or manufacturing equipment, assembling hardware, developing test plans, running tests, analyzing results, troubleshooting failures, and implementing the next iteration. It integrates low-loss cryogenic storage, reverse Brayton cycle (RBC) thermal control, and turbomachinery-driven propulsion to make spacecraft more agile, resilient, and responsive.
