Space arks were a type of spaceship that were large enough to evacuate large populations from a planet and then colonize another world.
On the planet Krypton the construction of space arks, or any other type of spacecraft was outlawed after a certain incident involving Jax-Ur.
This made it impossible for Jor-El to construct space arks when Krypton finally did explode, and he was only able to construct a smaller version of a space ark.
