Starfall is explicitly designed for mass production (like Starlink satellites), so unit costs drop sharply with volume. It is tiny compared to a Starship upper stage (~2.1 t dry mass vs. ~85–100 t), with far simpler systems (no main propulsion, parachute landing, jettisonable shield). Here is a realistic BOM (Bill of Materials) breakdown and cost ...
