Module 1 — Foundations
Intro Introduction to Spacecraft I&TWhy I&T exists, what it costs when it fails, and the philosophy behind every test campaign → 01 The I&T program — Structure, Documents & ReviewsIntegration levels, program phases, governing documents, and the I&T plan → 02 Configuration Management and the As-Built RecordTracking what was built, controlling every change, knowing precisely what was launched → 03 Quality Assurance — The Engineering Discipline of TrustQA roles, inspection types, technician certification, and stop-work authority →
Module 2 — The Work Environment
04 The Cleanroom: Where Discipline Meets Flight HardwareContamination control, electrostatic discharge, FOD accountability, and the culture that holds it all together — from clean tent to high bay. →
