What is this ? Hair, fiber, thread ?

Hmmm, I don't know; looks interesting. If it's not debris from the landing, maybe it's some sort of crystal?

Not crystal, and definitely not hair smile.gif
It's a fiber from earth, and it looks to be 40-50 microns thick and 1.5-2 mm long.
Sorry but I don't see anything interesting about it.

The most likely explanation is that it is something off of the spacecraft.. but playing the odds is so easy.

The telltale has been quite active lately. Maybe it's a shred of that damaged material that was tossed about in the recent breezes.

For the record, I agree with you. The odds are that it is something from the spacecraft. But just to play the devil's advocate, what about an asbestos type of mineral? Those can be parted into fibrous pieces, can they not?

Wouldn't that be interesting? We've been seeing that apparently frayed bit of thread in thousands of telltale images for a long time. Still, it would be quite a coincidence. mellow.gif

It's a thread from one of Pathfinder's airbags.

Hey, it's had more than 10 years to get blown halfway across the planet, right?

Has any chrysotile been found near Phoenix ?
My martian geology is nonexistant, but I googled this, where it says that chrysotile is "a hydrated magnesium ortho-silicate... " Are there such things around ?

I wonder if it is a fibre that somehow come off the WindTeller? I think it is. What are the odds of that being a fibre from Mars Pathfinder airbag? Billions to one against, Trillions to one against? Just a thought.

I believe it's some sort of Mars-originating object. Mineral, vegetable, or animal would all be interesting.

On another forum Hortonheardawho posted a sol 74 image of this cell. No fibre in that image. I also note that the sample itself has changed to a degree in this later imaging. So either the strand comes internal to the OM system or they are trying to re-use cells. But if they were surely they would have said something. Wouldn't they?

A far as I know, these minerals have not yet been confirmed to exist on Mars. Since they are relatively common on Earth, I see no reason to doubt they could also be relatively common on Mars, despite the somewhat different geological histories of the planets. I think there are other geologists here who could offer more insight along those lines than I am able to provide.

But as you say, we are playing with odds here. During my lifetime, I have looked at a lot of samples of things under various microscopes, and I have very infrequently noticed fibrous impurities in mineral samples on Earth...and I never found an obvious chrysotile impurity in the sample, regardless of the fact that chrysotile is a relatively common mineral in the mines of Earth.

For me, finding a microscopic fiber on Mars seems to strongly suggest that the thread took a ride from Earth, as all the previous fibers have.
