Strange Globs Could Signal Water On Mars
Joshua.Niland writes "Strange globs seen on the landing strut of the Phoenix Mars lander could be the first proof that modern Mars hosts liquid water. Images from the robotic craft show what appear to be liquid droplets growing, merging, and dripping on the lander's leg over the course of a Martian month. Just when is NASA going to fix that leaking roof on the backlot?"
I thought we already had the signals with the sublimation we caught on camera. Then some more potential evidence with the snow. I think we should be reaching the point where we can start talking about this stuff as possible evidence rather than saying "signal" like we are surprised.
The only change I can believe in is what I find in my couch cushions.
We sent a robot to look for water on Mars. It lands in an icy puddle, and gets covered in mud and tiny droplets (that behave just like water). But we can't tell if it's water or not. Your tax dollars at work!
Oh the precious tax dollars!
You do realize that scientists have a higher burden of proof, right? They aren't going to say it's water until they analyze it and can confirm with certainty what it is.
Damn right it's my tax dollars at work, and millions of us approve of it.
It must have been something you assimilated. . . .
Because of discoveries on Mars a few years ago, I registered the domain name martiansprings.com.
I get these late night brilliant ideas that go nowhere. I was picturing bottled water sold as a souvenir gimmick in science museum gift shops.
Some say I'm bipolar.
This space available.
Would this "dog" be green and have a broom on his head?
That condensed on the metal parts of the rover
Not to denigrate the achievements of the Phoenix lander, but this is exactly why the people who advocate robotic planetary missions over manned ones are wrong.
We didn't detect this water using Phoenix's million-dollar spectrometer designed to detect hydroxy compounds, or whatever. We detected it by adding a $20 digital camera that happened to be capable of pointing at some metal struts.
If you want to discover new stuff, you want to leave room for serendipity. Unfortunately, because Phoenix is a purpose-designed robotic platform, we can't ask any more questions about what the condensing substance is, or what else is in it. No matter how advanced they become, we can only tease ourselves with robots. To really check the place out, we have to go in person.
