Can you lose your Pre-Order ship?

No Man's Sky offers exclusive ships to players who pre-ordered the game (in my Case the Horizon Omega, since I have the Steam version). As discussed in this question, you can only have one ship at a time as your old one disappears when you get a new one.

This made me kind of afraid of actually redeeming my pre-order ship. What happens if I start using it, and then decide to buy another one? Will my pre-order ship disappear forever, or will I be able to redeem it again / get it back another way? If it's really exclusive to pre-orders, it'd be a shame to lose it.
