[Star Trek: DS9] How did the Ancient Bajorans get their solar sail craft into space?

Commander Sisko, upon returning from a conference on Bajor, presented his son with a set of blueprints for an ancient solar sail craft that was supposedly used to traverse the Bajoran system and allegedly made it all the way to Cardassia, but the question is, *how?*  If they didn't have the technology to recirculate oxygen, how did they even get the things into space?  Using a photosynthetic plant to recirculate oxygen wouldn't be nearly sufficient to last more than a few hours, if that, and solar sails are hardly durable enough to survive interstellar travel.

We can get things into space without warp, why couldn't they? Also do they say there was no oxygen re-circulation? They could have always brought along tanks of oxygen if they didn't have that technology.
