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
