Superscience Mars

"Superscience Mars is the Red Planet as it appeared in
classic science fiction B-movies. This is Mars as a naturally habitable world, home to a powerful advanced nonhuman civilization.
Superscience Mars resembles the real Mars in size and superficial geography, but is considerably more dense and massive. Its composition includes a surprising quantity of heavy metals, giving the planet a density 1.5 times that of Earth, and a mass of almost 0.2 Earth masses (twice its real value). The surface gravity is higher, too – 0.8 standard G. The dense interior of Superscience Mars generates more heat and gave the planet a thicker atmosphere, which in turn keeps the climate warmer. For most of its history, Superscience Mars was only a little colder and drier than Earth, and was a fertile habitat for life."
