STL Drive

STL Drive allows your BYOS ship to travel within the same star system.

It's very cheap (all materials for it can be found on the first Garden planet), and with it you can reach at least one Forest planet, Desert planet and Moon (they are always present in your starting system).

Limitations

 * STL Drive doesn't provide faster-than-light travel. To fly to another star, you would need a Small FTL Drive instead.

What about non-BYOS ships?
Non-BYOS ships get their FTL drives automatically repaired after reaching the Outpost, upon speaking to Esther Bright for the first time.
