Rocket Lab
Make one change. See why the flight moves.
Build a readable model rocket, choose a motor, launch a short deterministic simulation, and follow thrust, mass, drag, stability, recovery, and landing in one calm native experience.
Offline learning lab
From component stack to flight story.
Rocket Lab keeps the first experience visual and inspectable. Change a mass, fin, motor, rail, wind, or recovery setting, then see the explanation alongside the replay.
Build with guardrails
Start with a friendly template and edit the parts that matter. Missing motors, impossible geometry, and unstable designs fail visibly.
Replay the model
Follow altitude, velocity, thrust, acceleration, mass, drag, static margin, recovery, and landing in a deterministic local run.
Bring your files
Import native projects, RASP motor curves, and a deliberately bounded OpenRocket-format subset with provenance and compatibility notes.
Honest scope
Built for intuition, not launch approval.
Rocket Lab is an educational vertical-flight model, not professional flight software, manufacturer data, launch certification, safety advice, or exact parity with another simulator. Core calculations and imports work offline; exports leave the device only when you choose to share them.
