I would need to see how you have your colliders setup. The rocket has two colliders, one for the main body and one for the fins. If the launchpad has a collider and all your rocket colliders are setup properly the next thing to check is if your colliders have “is trigger” checked on. If this is checked on the colliders will not act as solid objects. Another you could enable is “convex” on the mesh colliders on the rocket. Sometimes mesh colliders can act weird when used with a rigidbody if this is not enabled. Outside of that I’d have to look at your project to see what the issue is.
