Kim Stanley Robinson's Mars trilogy filled us all with hope that we could terraform Mars in the 21st century, with its plausible description of terraforming processes. But now, in the face of what we've learned about Mars in the past 20 years, he no longer thinks it'll be that easy. Talking to SETI's Blog Picture Science podcast, Robinson explains that his ideas about terraforming Mars, back in the 1990s, were based on three assumptions that have been called into question or disproved:
1) Mars doesn't have any life on it at all. And now, it's looking more likely that there could be bacteria living beneath the surface. 2) There would be enough of the chemical compounds we need to survive. 3) There's nothing poisonous to us on the surface. In fact, the surface is covered with perchlorates, which are highly toxic to humans, and the original Viking mission did not detect these. "It's no longer a simple matter," Robinson says. "It's possible that we could occupy, inhabit and terraform Mars. But it's probably going to take a lot longer than I described in my books."Read Replies (0)

Since 2012, WikiLeaks founder Julian Assange has been holed up inside Ecuador's embassy in London trying to avoid extradition to Sweden, where he faces a sexual assault investigation. Now, after the case has been stalled for years, Swedish prosecutors are arranging to come to London and question Assange within the embassy. According to his lawyer, Assange welcomes this, but Sweden still needs to be granted permission from both the UK and Ecuador. "Assange's lawyers, who are appealing against his arrest warrant in Sweden's highest court, have complained bitterly about the prosecutor's refusal to travel to London to speak to him – an essential step under Swedish jurisprudence to establish whether Assange can be formally charged. [Lead investigator Marianne] Ny's refusal, they say, has condemned Assange to severe limitations on his freedom that are disproportionate to the accusations against him." Ny has also requested a DNA sample from Assange.Read Replies (0)
