Doom

Doom! Nostalgia.

The Martian moons

Crappy moons that can barely form a potato. Phobos and Deimos. Delineating between moons, planets, and all the other stuff. The likely origin of the Martian moons.

Space marines

Corporate space settlement and operations. Space Force. Josh reviews space marines; again. Martian weaponry.

Settling mars

Where to build? The cost of scratch settlement construction. Caves and lava tubes. Teleporting resources changes the game.

Ancient aliens

The Prometheus Problem, again. Doom humans-on-mars hypotheses: aliens developed humans on Mars vs humans originated on Mars. Species resurrection. Gene therapy. Chromosomal addition and subtraction.

Martian miscellany

Nano walls! Water on Mars! Telefragging!
