Definition
A core engineering mindset at SpaceX characterized by the use of unconventional, low-cost solutions, scrounged hardware, and “good enough” components to achieve mission goals for a fraction of the cost of traditional aerospace methods.
Why It Matters
Scrappy engineering is the ‘New Space’ antidote to bureaucratic bloat; it proves that ‘good enough’ components and scrounged hardware can achieve for millions what traditional aerospace fails to do for billions.
Core Concepts
- Scrounging: Actively searching for abandoned or surplus hardware from legacy government programs (e.g., buying The LOX Ball for $86k instead of $3M).
- COTS Substitution: Using commercial off-the-shelf electronics (e.g., standard PC components, sensors from the auto industry) rather than “space-hardened” ones costing 1000x more.
- Makeshift Infrastructure: Using temporary tents, repurposed railroad winches, and “garage-style” assembly areas rather than billion-dollar clean rooms.
- The “Chevy Strip” Rule: Performing complex repairs in the field using simple hand tools and “technician’s intuition” rather than waiting for multi-month factory refurbishments.
