I think this guy, Joop, is a parapsychologist. Extreme skepticism is warranted.
The Phoenix lander could check out whether there is life on Mars. That lander is set to arrive on Mars around May 2008.
I suppose it is hard to be credible with a name like: “Joop Houtkooper”.
Extreme skepticism is my default position on about everythying, including this. But the science from that lander was been very interesting and I've always had the suspicion that embarrassing (that is to say, not easily explainable) data were swept under the rug. There have been credible scientists with credible-sounding names who have argued all along evidence of life was found. (I'd have to research the details to refresh my memory but a lot has been published about this).
