East Gap Mars is the version of Mars present in universe of the East Gap (Earth East 2,217,643).

There was oxygen and methane in the air of this world - chemically unstable gasses that must have been injected by the processes of life. There was some kind of vegetative covering on the lower ground of the northern hemisphere.

The lifeforms present on this planet came from Earth lifeforms that travelled through the vacum of space (a phenomenon called panspermia).[1]

The Long War

During the East Twenty Million mission, the Zheng He and the Liu Yang traveled through the East Gap, and sent some probes into space.[2] They discovered life on this world as well as this universe's version of Venus (East Gap Venus).[1]
