What it is
Materials and substrates qualified for use in space — radiation-hardened, thermal-cycle-tolerant (±150°C+), vacuum-stable, manufactured to MIL-STD or NASA-STD reliability bars. Historically a niche defence/aerospace category dominated by US incumbents. Now becoming larger because:
- Cost-down on launch (SpaceX) opens commercial space.
- Lunar landers + space industrialisation create demand for surface hardware.
- Defence policy (CHIPS Act, EU sovereignty programs) funds onshoring.
Why this matters (investment relevance)
Most of these are positioned for terrestrial AI/data-centre markets first, but the space adjacency is a real second-order opportunity worth tracking.
