QUOTE "I want to retract the claim in the paper that the smooth area we discussed was 'standing liquid water'," Levin acknowledged on Tuesday. "I am sorry that we made such a large mistake." Duuuuuuhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. But it was blue! Blue I say! |

Actually, the retraction was quite magnanimous, even if unavoidable. And if Levin and Lyddy had followed normal peer review, which usually involves two or three anonymous reviewers mediated by an editor, the slam, which might have even been harsher, wouldn't have been public. Indeed, the criticisms in this thread and elsewhere on this claim are far less harsh than some reviewers' comments I've seen on other far less controversial work.

What an astonishing few days! As certain as we were of this, I'm shocked that Levin retracted so quickly - I had been thinking he might dig in and claim other examples on level ground, for example.
There's still a big question looming here: Levin knew this was inside Endurance crater, but didn't check the slope?! Given New Scientist's swift action on this, my opinion of them has recovered somewhat. |

The thing I can't figure out is how he was allowed to present this at all. Doesn't the IEEE even do a "sniff" test on these things? It didn't take me even one minute to start smelling a rat when I was reading it. Something that sensational you would think they'd ask someone.
How did he think the water got there. Rain? Ground seep? You know what they say, "Where there's smoke, there's fire." For that much water to spend anytime on the surface, there would've had to have been a lot of "smoke". Cloud to percipitate from. Run-off erosion. Water bourn mineral deposits. The place would be littered with evidence of recent water activity. The other side of this is the insult to the MER team. To make such a claim is to imply complete incompitance on the part of the people running the mission. That they would command the pancam to take a multispectural image of the ground right in front of the rover and not see a puddle of water -- that is insulting. |

Got this in my email this afternoon:
QUOTE Hello, Thank you so much for your message. I have just gotten back from vacation and have been working with the reporter to find out what happened with the story. The researchers have retracted their claim, and I am writing a blog explaining what happened (copy pasted below). We will have the story and blog updated shortly. Thanks so much for writing in - I really am grateful for your letting us know about this. Best, Maggie |

That's nothing. Here's what Maggie said to me:

Hey, at least she used "Dear" with you and not simply "Hello." No doubt New Scientist's form letter robot would insert "Hi" in the next salutation.

Good to see that there are lots of honestly red faces over this...integrity still lives at New Scientist, it seems, and this should be positive in the long-term...they won't do this so casually again.
Too bad, though...really wanted me one of them Lichen Brides (thanks for laughing, Ed! ) -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I have to admit that I almost burst out laughing upon finding out about this.
For that reason, in a way, I'm grateful to the authors, and to New Scientist. It's been a lousy week, and I really needed something to cheer me up. |

What a credit to this "amateur" community.
I do not poo poo the idea of brief moments of "wet" ground in low altitude locations... would really love a rover at the bottom of the Hellas basin. Given all the detections of salts in the surface, can envision places where dampness may exist briefly..... But I really CANNOT understand how any one could make such claim and not look at the larger context imaging. Slope a dope.... As for Gilbert Levin.... I do applaud him for sticking to his guns regarding his LABEL RELEASE data from Viking. Occam still weighs heavily against the results being proof of metabolic activity.... but it has not been outright disproven.... And we should not be afraid in science to say.... "results were inconclusive". That is how a scientific experiment works. I saw all too many PR releases during and after Viking that proclailmed Viking found NO evidence of life. Mars is dead. PERIOD. Time, more exploration, more experiments, will tell..... Lets just keep a sceptical mind, but open mind, and keep exploring ..... Mars is not Earth... What a great community this is....amateurs and professionals, and this forum just ROCKS!!!!! Craig |

It does indeed, BP, it does indeed...
Generally, uncertainty in experimental results means that we haven't asked the right questions, or our methods to answer said questions were not applicable. Therefore, such results serve as constraints (i.e., this didn't work as we thought it would--why?), and thereby lead to improved questions and more refined approaches to answering them. Viking really landed in the blind in so many, many ways, and the labelled release experiment assumed an inorganically non-reactive surface. The only way to interpret the results is , and search for alternative explanations as well as flaws (not errors; this was done as I said completely in the blind) in the experiment's approach, which is precisely what the larger scientific community has done. The fact of the matter is that there was no conclusive evidence one way or another, so the experiment's scope was too broad to identify specific nuts and bolts of the observed process. This is instructive and valuable, but it also means that no conclusions whatsoever can be derived from the data. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

"And if Levin and Lyddy had followed normal peer review"....
The real problem is they hadn't followed norms of competent scientific research. |

I'm sure the New Scientist web site was swamped with messages (I know I sent one...) that must have made all the alarm bells go off.
Too bad the editors didn't have the COMMON SENSE to ask themselves "why is this momentous discovery being made by an engineer working far away from the Rover science team?" "Why is this being discovered only years after the images were taken?". Frankly, all this points towards a hoax, as it surely was, not even Levin could have missed the incline of the area in question. - This reflects extremely badly on the New Scientist editors. |
