talking and writing about your conviction that mars can be, i think this is the right word, terraformed ? you can adapt the atmosphere around mars, you can use magnetic shields to place between mars and the sun to somehow transform mars into a place that is conceivably long term liveable for human beings. it would cost not even hundreds of billions of dollars to make that come true surely, trillions of dollars? inconceivable amounts of resource, time and money. what on earth is the point of going down that track? oh, it s really quite simple to understand. we have the ability to really look at the weather on mars, to understand the physical phenomena of evaporation, transport, clouds forming, to really, really get into the climate of mars. and as we do that, we also learn how to do a betterjob of developing the programmes
to really, really get into the climate of mars. and as we do that, we also learn how to do a betterjob of developing the programmes for predicting climate here on earth. so, comparative planetology has been really important to us. we re in the era of climate change that everyone hears or talks about. as a planetary scientist, i can tell you the climate on earth has done nothing but change, and what we re moving into is a rapid change, period. moving into is a rapid change period. what happened to climate on mars? mars also went through a rapid climate change. it was a blue planet early on and now, it is a desert and cold at that. and so, consequently, the concepts that i do in terms of future thinking about how we can live and work on mars are done in supercomputers, where we look at the physics
