Could we terraform Mars?
In this video from PBS Space Time, hosted by astrophysicist Matt O'Dowd, we look at the science and technology required to transform our planetary neighbour into a second Earth.
We already have the technology to bring humans safely to Mars and set up small settlements – or at least could do, within a generation. But those settlements will need to be cocooned – shielded against the deadly cold, intense radiation, and the fatal lack of atmospheric pressure.
Surely if we want to thrive on Mars – to make it into our second home – these settlers, or their descendants, will need to be able to open the airlocks, shed their spacesuits and step out onto a survivable surface. We'll need to terraform Mars, as our first step in terraforming the galaxy.
