[Tech] Terraformare Marte? E preservare Terra, invece?

La NASA sta iniziando a valutare seriamente l'idea di terraformare il pianeta rosso, trasformandolo in una seconda, piccola Terra:

This startling concept will be the focus of a major international debate, to be hosted this week by America's space agency, Nasa, which is preparing a multi-billion-dollar Mars research programme at the request of President Bush. Leading researchers as well as science fiction writers, including Arthur C. Clarke and Greg Bear, will attend.



'Terraforming has long been a fictional topic,' said Dr Michael Meyer, Nasa's senior scientist for astrobiology. 'Now, with real scientists exploring the reality, we can ask what are the real possibilities, as well as the potential ramifications, of transforming Mars.'

Alcuni però, giustamente, si chiedono che cavolo si sono messi in testa alla NASA:

'The idea of terraforming Mars is extreme, but it is not cranky - that is the truly horrible thing about it,' said Paul Murdin, of the Institute of Astronomy, Cambridge. 'If it was just a silly science-fiction notion, you could laugh it off. But the idea is terribly real. That is why it is dreadful. We are mucking up this world at an incredible pace at the same time that we are talking about screwing up another planet.'

'It is very depressing. Before we have even discovered if there is life on Mars - which I am increasingly confident we will find - we are talking about undertaking massive projects that would wipe out all these indigenous lifeforms, all the strange microbes that we hope to find buried in the Martian soil. It is simply ethically wrong.'
