Imagining how other worlds might be terraformed leads into the science and speculation of turning hostile planets or moons into places where life could survive. These posts look at the possibility of changing atmospheres, temperatures, water cycles, radiation levels, and surface conditions on worlds such as Mars, while also considering the enormous technological, ethical, and environmental challenges involved. Terraforming raises big questions about humanity’s future in space, the limits of planetary engineering, and whether we should reshape other worlds simply because we might one day be able to.
