这就是生命，我知道，我看到它就知道

425
00:23:54,965 --> 00:23:56,980
It was clearly a positive response.

I sent out for cigars and champagne.

438
00:24:44,785 --> 00:24:46,530
My best guess at this point would be--

439
00:24:46,530 --> 00:24:48,320
The general interpretation was well,

there must have been something geologic

or some property of the soil on Mars

with the presence of perchlorates

Norm Horowitz's position was very strange.
诺姆·霍洛维兹的观点很奇怪

There's no evidence there there is a --

He said not only is there no life on Mars,

I feel he was not objective (laughs).

Scientists has to keep an open mind.

The concept of saying, okay, we found life

471
00:26:10,590 --> 00:26:14,890
So you had a positive indication for each one of those.

472
00:26:14,890 --> 00:26:17,909
The other two life detection tests were negative.

with the instrument looking for organic matter.
用仪器寻找有机物的时候出错了

highest-ranking scientists had their say
