SpaceWasm is a no_std WebAssembly 1.0 decoder, validator, and interpreter written in Rust, developed at NASA JPL for executing Wasm binaries on-board spacecraft. It provides streaming decoding with fixed memory usage and a sandboxed interpreter designed for flight-compliant, embedded environments.

Use cases

• run webassembly modules on spacecraft flight software
• embed a sandboxed wasm interpreter in a no_std embedded system
• decode and validate wasm binaries with bounded memory usage
• standardize spacecraft activity sequencing with webassembly
• execute untrusted low-trust code on-board with restricted access
• port wasm workloads across flight platforms

When to choose

• you need a flight-compliant or safety-critical wasm interpreter with deterministic memory use
• your embedded environment requires no_std support
• you want to sandbox untrusted executables on-board with restricted compute and hooks

When to avoid

• you need maximum execution speed for direct bytecode interpretation
• you require wasm features beyond the 1.0 specification
• you need a general-purpose desktop or browser wasm runtime
