Free, polished tools for high-power rocketry.
Fusion Space builds and maintains open tools for the hobby rocketry community — careful about the data, free to use, and made to be genuinely useful at the bench.
Projects
4 liveHPR Motor Finder
LiveLive AeroTech, Cesaroni & Loki motor stock and pricing, aggregated across the major U.S. vendors and matched against ThrustCurve — so you can see who has a motor in stock without checking every vendor by hand.
- Motor availability
- Price tracking
- Free JSON API
Charge
LiveA black-powder ejection-charge calculator for high-power rocketry: size by chamber pressure or shear-pin force, see every constant in the formula, and close the loop with a ground-test log so you fly the charge you actually validated.
- Ejection charges
- Ground-test log
- Sizing calculator
Window
LiveA launch-weather board for US high-power and model rocketry: surface wind against the 20 mph limit, winds aloft up to waiver altitude, storms, cloud ceiling, and a multi-day outlook for any field — one honest view, fetched live in your browser. No go/no-go verdict.

- Winds aloft
- In-browser
Muster
LiveMotor-hardware compatibility for high-power rocketry. Pick a reloadable case — AeroTech RMS, Cesaroni Pro, or Loki Research — and see every reload it flies, the closures and spacers each needs, its certification, and the full reusable-hardware shopping list. Or start from a reload and work back to the cases and parts that fly it.

Debrief
In developmentA universal, in-browser altimeter flight-log analyzer. Drop in a file from any logger and get apogee, max velocity, max-Q and the curves that matter — with the real-world mess (ejection spikes, sensor noise, mixed units) handled. Analyzes flights you've already flown; not a simulator.
- Flight-log analysis
- Altimeter data
- In-browser
Loft
In developmentA high-power rocketry flight simulator that runs in your browser and on a phone. Import an OpenRocket .ork design and get apogee, max velocity and Mach, stability margin, rail-exit speed, and descent and drift — with the model's assumptions and accuracy shown against OpenRocket's own stored results. No accounts, no tracking, no go/no-go verdicts.
- Flight simulation
- OpenRocket import
- In-browser

More free tools for the high-power rocketry community are in the workshop. New projects land here as they ship.
About
Fusion Space is an independent project building free tools for the high-power rocketry community. Everything here is made to be genuinely useful at the bench — fast, careful about the data, and free to use, with no ads, no accounts, and nothing following you around.
The tools are open source, so you can see exactly how they work, check the data yourself, and build on them. If something's wrong or missing, the source is a click away.
- Free & open source
- Every tool is free to use, with public source you can inspect and build on.
- No ads or tracking
- No accounts, no ads, and no analytics that follow you around the web.
- Built for the bench
- Made to be genuinely useful to real rocketry hobbyists, not to impress.
