#22Confirmed! Mars has liquid water.

And that someone seems to be this lady, with this most BAMF job responsibility ever:
“These are ongoing conversations,” said Catharine A. Conley, NASA’s planetary protection officer, who coordinates the efforts to minimize the chances of life inadvertently crossing the solar system.

#25Earlier quoted context omitted.
The article mentions how equipment that needs to be sterilized is baked to a very high temperature - but I wonder, can it not be sterilized with radiation, like we already do with food? All electronics on a rover are already radiation hardened, after all Curiosity has to work while having a chunk of plutonium strapped to its back. Is this not an option of some reason?
What happens when Curiosity contaminates the RSLs with radiation?
Humans did not invent radiation, you know. In fact we live in a remarkably well-shielded area. Certainly better shielded than the surface of Mars.
Besides, we're on another planet. If our payload was nothing but the nastiest chemical we could come up with, we still couldn't ship enough to Mars for it to matter.
No, the only payload that could conceivably be harmful is one that can self-replicate, which at this juncture means life. (Ask again in a hundred years.)

#26If there is water of any sort on Mars, ice, liquid, salty, whatever, I think finding life on Mars is inevitable. Life is very, very persistent, and niches will be filled.
Unfortunately it's also all but inevitable that we'll bring some with us, if we haven't already. Life is persistent, and ever-surprising.

Interesting. I read that in Jeff Goldblum's voice as well. Were there any missions that lifted off Mars and came back to Earth ?

No, we don't have the capability to land something on Mars with enough fuel for it to take off again.

Didn't MSL and Curiosity (Gale) both get pretty close?
