Posing this question (and most answers) indicate severe lack of understanding of basic orbital physics. Here's a shortlist of facts and probably reasonable ideas: Orbital period is in direct relation to the radius of the orbit (we speak of circular orbits here). This means that anything orbiting the Sun between Earth and Mars is at some point at this "mid"...

Is a midspace space station between Earth and Mars practical? Here's a naive view: The problems with notions like a "halfway" station is that the locus of points halfway between Earth and Mars is probably a thick disk with an radius about equal to the average of the average of Earths and Mars orbital radius. Mars also has the second most eccentric orbit of ...

It's hard to guess what is in the mind of another contributor, but... Using a cycler model could involve a network of space ports, and the cycler would take the role of a "midway" space station (it taking care for the cargo for the portion of the journey between Earth and Mars) In Earth orbit, there would be a staging post or spaceport. Launch vehicles ...

You're right: this has issues. You can insert a station into a circular orbit halfway between Earth and Mars, but because this has an orbital period also in between those of Earth and Mars, your station won't be in a usable position most of the time. So you'd have to fill the orbit with several station to always have one reasonably close. The fuel is also ...
