【英音模仿秀】火星上有水？

模仿文本： But why is it so much more irritating, and so much harder to ignore than just overhearing a full conversation? New research may have the answer, later in the programme. First though, to Mars, NASA's Curiosity rover has been phoning home with the results of new experiments this week, which suggests that conditions on the Red Planet may have supported life. Mars is, of course now, dry and dusty, but it seems that wasn't always the case. Our space expert, BBC Science Correspondent Jonathan Amos is here. John, what exactly have they found?
