Mars & Jupiter

A permanent Mars outpost would be a complex life-support and logistics system, not simply a collection of habitats placed on the surface.

Food production on Mars would need tightly controlled light, water, nutrients, temperature, atmosphere, and microbial conditions.

Terraforming means changing a planet’s environment on a global scale; for Mars, the gap between concept and demonstrated capability is enormous.

Jupiter’s moon Europa is a major astrobiology target because multiple observations support the possibility of a salty ocean beneath its icy crust.

Europa, Ganymede, and Callisto offer different environments for studying water, chemistry, energy, and the limits of habitability.
