The biggest obstacle to a truly livable colony on Mars is the planet's harsh environmental conditions, including extreme temperatures, high radiation levels, and a thin atmosphere lacking breathable oxygen. Additionally, the challenges of sustaining life—such as producing food, water, and energy, as well as creating reliable life support systems—pose significant technical and logistical hurdles. Establishing a self-sufficient colony would also require extensive infrastructure development and continuous supply chains from Earth, complicating long-term habitation.
