In Portal, using the portal gun to get to the moon is the obvious space travel usage, but I think people are overlooking how it’d let you trivially break the rocket equation.
Hell, you could build a >1g torchship using nothing but the ocean.

@[email protected] drop a magnet in a cylinder with a portal at the top and bottom, and you have a free infinite-power generator (assuming the portals take nearly no power, and you’re in an accelerating reference frame)
Take your >1g water-torch ship, use it to kickstart the generator above, use the power from that to accelerate ions in a cylinder (with a portal at top and bottom). Eventually, your ion-based thrust is enough to cutoff the ocean portal. Reactionless thrust! + Particle beam cannon on-demand
