It has been a while since I played, but afaik ypu can always just self-destruct the ship through one of the side menus or keybinds, and then you can either pay insurace cost to get the same ship repaired, or abandon it for the default ship, which should also respawn you somewhere sensible.

I don't recall if there's any story or anything else ypu'd want reset, the tutorial is standalone and since it's a sandbox I don't think there's much else to reset.
