back to article NASA: Mars is good habitat for Terry Pratchett dragons

In a development which may untwist a few knickers around the internet, NASA scientists have now explained just what their Phoenix robot lander has found in the soil of Mars - and what the implications are for possible discovery of life on the Red Planet. Following news that the White House had received secret briefings in …

"The chance that we are following this correctly is roughly equivalent to that of a man with no arms throwing a handful of jelly through a falling doughnut at fifty yards without touching the sides."

Have you tested this out? If so I want to see the video, purely for scientific authenticity you understand and not for the sole purpose of laughing my arse off.

Dumb conclusions ....

And if I'm following this right, they've found evidence of a substance used in rocket fuel, near where they've landed their rocket?

perchlorates are dangerous

Granted, in very small quantities and handled carefully, they are ok, but perchlorates mixed with organic substances (such as petrol, alcohol, etc.) are quite likely to go explode, hence their use in rocket fuel. A perchlorate is ClO4 (negative charge), and wants to oxidise most things it comes in contact with.

Never mind that they can also be shock sensitive, this is just bad science coming out of NASA, and I agree with the comment about finding perchlorates near where they landed. seems a bit odd.

Rocket fuel

"evidence of a substance used in rocket fuel, near where they've landed their rocket?"

Landed a rocket that uses a completely different type of fuel to that discovered. Which is technically an oxidiser and not a fuel anyway.

Don't you know that million-to-one chances come up nine times out of ten?

I'm all about science, mind, and drawing conclusions, but suspect CharleyBoy's comment isn't far off the mark.

In any case, the only conclusion NASA seems to be making is 'there are perchlorates on Mars'.

Behind the scenes, people deep inside NASA are no doubt wondering why they upped the hype so high, when the only conclusions that could reasonably have lived up to the hype (life definitely does / can not exist on Mars) are the least likely by far...

Slashdot FTW

Here's some stuff from yesterday's Slashdot discussion on this topic, paraphrased for additional inaccuracy:

* Lithium perchlorate liberates oxygen when heated. Perchlorates may be useful for creating oxygen on Mars.

* Other perchlorates are useful as a rocket fuel. Perchlorates may be useful for getting craft off of Mars.

* The perchlorates they have found are probably not contaminants. AFAICT it's like finding diesel under the car when it runs on petrol. Of course contamination can't be completely ruled out this quickly. It's a preliminery result.

* Which perchlorate have they found? It does make a difference!

But basically the gist I got was that perchlorates might be a very useful thing to find on a planet you might want to visit, stay awhile on, and then return from.

Now If NASA used an Infinite Improbability Drive they could use the jelly throwing man to power their ships...

Nothing to see here, move along now

had NASA not got their own knickers in a twist by dint of underestimating the public's ability to comprehend such mind-fucking concepts as "We might have found something, but we're not sure yet, can we get back to you on that?" and then running scared from the Interweb conspiracy bearpit, this would have just been an entry in the (very informative) Phoenix blog, rather than a headless chicken exercise

*sigh*

While I'm on, the perchlorate used Phoenix's rocketry was only a part of the Delta launch vehicle, not the lander itself. There was no contamination detected on landing, and the scoop was scraped clean on other soil samples: any perchlorate in these samples hasn't come from Earth.

Of course another thing perchlorates are good for is getting things whiter than white - at least when hot enough, say around 60 degrees [0] , that they decompose into lots of lovely stuff like hydrogen peroxide.

@ac re: million-to-one

Aye, and if hollywood is believed, nine times out of ten they bloody well turn up in california, where they're beaten off by the pretty dude, the sassy woman, the geek and the dog.

To be serious for a moment, correct me if I'm wrong, but didn't the polar lander drop down on a parachute for the final part of its landing? With an airbag? No rockets involved...

And now, I've just realised what some of the mysterious "box shaped" objects in the earlier photographs actually were... the supposed "machinery on mars" as, I think a Mr Hoagland had it, is actually The Luggage!

Your title reminded me of "The Game of Rat and Dragon" an excellent short story by Cordwainer Smith. Humans and cats, partnered up to fight aliens, which the humans see as dragons, but the cats see as rats.

Not entirely unexpected

The Viking missions were the first successful landers designed to look for signs of life. They found carbon dioxide was released when Martian soil was wetted and nutrients added. The initial suspicion was that microbes had been found in the soil and had been incubated, but later tests showed that biological reactions were unlikely and that the soil must contain a powerful oxidising agent.

The big question for the last thirty years has been to try and work out what it is in the soil. Peroxides have been a favourite, but it looks like perchlorate ions are the guilty parties.

Now it'd be nice to know what sort of concentrations we're looking at - high quantities would pretty much remove any possibility of life at this site since perchlorate reacts strongly with organic molecules.

Confusing the hymn and the hymn-sheet

Where there's rocket fuel, there's life, for sure. Presumably NASA pointed a finger at the lander engine maker, who then said "It wasn't us, guv, honest". Ergo, it must be life on Mars.

Whatever NASA, ESA, and other rocket-propelled boffins get up to, it's not "science". Science requires (a) honesty in regard to facts (to tell apart truth and falsehood), (b) possession and use of a faculty of logical thinking (to deduce correctly from facts). Tendentious and tedious, but essential now that science has gone postmodern and scientists rely on the fiat dollar. Teaching science is not about making sure everyone sings from the same hymn sheet. "Scientists" like that need a Zen master with a big stick, to hasten the return to sense should anyone point a finger into space and shout out "The Moon!"

Just a Coinkydink?

So, at the same time NASA find Perchlorate on Mars, an Dutch research group published a paper that basically says, we've solved the structure of the microbial enzyme responsible for perchlorate metabolism in terrestrial bacteria.... can it really be a coincidence?

The only rockets on the Phoenix lander are monopropellant hydrazine thrusters used for the final part of its landing. No perchlorate of any kind could have been brought to Mars by Phoenix.

Don't forget

That everything us mortals read about the mission is the result of long discussions as to WHAT can be released and then is passed thru and partially digested by a press officer. So, for the time being don't make too much of anything in the press releases.

That said, I keep getting a mental picture of somebody standing/lying/slithering behind the cameras, laughing it's self into a puddle wondering what spurious evidence it can present next to the silly earthling's lander. Don't be surprised if the next remarkable chemical to be found on Mars chemically resembles urine !

Space - The final front ear

Still, I guess perchlorate is a good source for liberating oxygen though? Ammonium perchlorate might be the best form, having nitrogen and hydrogen.

I hope they are now doing tests on the earth based rover model, to see what responses it has, and if they might have detected it at the other locations. Before they performed this analysis, I believe they performed a baseline analysis to see what contaminants were present.

I trust they will name this sample location Errol!

so where did Obi-Wan b*gger off to?

on those Martian pix that were floating around a while back, my peridolia sensor observed that Mars was actually Tatooine, to wit, Obi-Wan Kenobi on a Krayt Dragon pretending to be the Little Mermaid, with at least *two* clearly distinguishable Jawa Sandcrawlers as well as loads of other stuff that I can see (oddly no-one else can, must be an alien conspirancy!)

So where are they now? All b*ggered off since they realised the silly Earth people were up to mischief, we saw all this coming during the Clangers. Earth people come with space podules, aliens hide under the ground, humans walk around for a bit and leave some junk behind, then go home, aliens come back out, steal the space junk and build hot-water central heating out of it!

@ Mike & mics

There was one on the Mars Polar Lander which went foom, so they didn't get any results from it. There _is_ a mic on board Phoenix, attached to the landing camera that was never used as a bug was found that meant if it transferred an image at the wrong time during descent, Phoenix would also go foom. Turning this mic on hasn't been ruled out at a later point in the mission, though there's no word on the roaming charges.

No sound has been recorded from the surface of Mars yet, but not for a lack of trying
