Columbia's Ghost Still Haunts Starship's Heat Shield

A HackerNoon analysis examines how the 2003 Columbia disaster shaped heat shield design for SpaceX's Starship. The vehicle uses a steel hull and pinned hexagonal tiles, but experts say rapid reuse remains unsolved.

• A 1.67-pound foam chunk punched through Columbia's RCC wing panel at over 500 mph
• The Shuttle's aluminum airframe had to stay below 175°C while the belly reached 1,260°C
• Starship uses a steel hull and pinned hexagonal tiles instead of the Shuttle's 24,000 tiles
• A reusable heat shield must survive heating without eroding, stay light and be inspectable
