#26 Re: Unmanned probes » Broken spherele has dark spot inside it???? » 2004-03-15 17:47:21

Unnerving!  Look around the edges of these layered plates of outcrop in the new photo below. (upper left edge, upper right edge, lower right edge) These Spherules are sticking out all around the edges of each slab! Any info yet on the composition of these Martian Blueberries? (I secretly hope that they officially name these spherules 'blueberries'.)

I really hope they clear this mystery up once and for all, before Opportunity moves on to Endurance...  but then again, maybe the mother-berry-lode of all berries will be waiting for us there! tongue   
But seriously, I want to know what these damnable things are made of! :bars: Before I go mad!!

Now excuse me while I go off and have a whopping slice of homemade blueberry pie!:;):

I say, if a full face impact, about 10 to 20 centimeters deep surface indentation. If narrow edge on, creating a trough or gouge in the surface soil, I'd say approximately half a meter deep and a meter to two meters in length. Judging from the view above the landing site, in the photo Atomoid provided, there appears to be a black/dark gorge marking - appears to be substantial given the distance from the cameras perspective to the surface. Unless, of course, it's a flaw in the picture....  or a dust trail.

That article was very interesting indeed, Atomoid. One immediate question that comes to mind is: Are there any concretion forming spherules on Earth that seem to form off of 'branches' or ' tendrils' and then drop-off to the ground as these appear to? I can't seem to get my head around an 'erosional' explanation on these images. Though given the .38 gravity and 1% atmospheric pressure coupled with the briney quality of the soil and so forth... It's so tough to come to any definitiveness either way. We humans are experts at 'seeing things that aren't there'. (But we're also great at NOT seeing what is plainly obvious and staring us in the face..) Even so, I have to concur with Shawn on this one;

I think we'll need more definitive evidence than this before we can rule out geology and start talking biology.

(But still, that doesn't change the fact that some of those pix give me the willies...) ???

Acually, I am wondering why there hasn't been more focus on these Spherules, or Sphericles, or Martianberries, or blackeyed peas, or whatever the hell these ballbearings are...
They are really freaking me out the more I see of them.
Take these for example:
[http://marsrovers.jpl.nasa.gov/gallery/ … 53M2M1.JPG]Pea Soup 1
[http://marsrovers.jpl.nasa.gov/gallery/ … 53M2M1.JPG]Pea Soup 2
[http://marsrovers.jpl.nasa.gov/gallery/ … 33M2M1.JPG]Pea Soup 3
Don't they look as if they are actually "surfacing"? The thought occured to me that they may be slowly, over large portions of time, kindof "bubbling" to the surface of their various rock formations. Kindof excreating spheres.
Other pixs show what looks not unlike a soapy kind of texture, spongy, yet rocky at the same time... with "porousness" not unlike certain kinds of coral I've seen pictures of...  It's a little unnerving that we haven't as yet seen any photo's from here on Earth that show anything comparable to these things. If these Spherules are common to geologists, then you'd think some comparison pixs would have surfaced by now? If these things are easily explainable then lets have some Earth analogue. Anyone?

A little OT here but,
Anyone know when the next Nasa MER broadcast will be? Seems they are making their press briefings fewer and fewer. I've been to both the Nasa TV page and C-Span and can't find much. Any other sites keeping up to date on the briefings, that anyone knows of?

#32 Re: Unmanned probes » Huygens Probe to Titan » 2004-02-05 23:14:17

Yes, if only we had the funding for more missions...throughout the entire Solar System.

Titan is a total mystery,... In terms of getting humans on there, it should be possible within this century I believe - very possible.

I hope outer planet exploration dosen't get left behind in the wake of all this Martian excitment. On with exploration!

Alas! if only there were enough life in ones lifetime to witness it all unfold!... sad

#33 Re: Unmanned probes » Which Mars site has you more interested? - Gusev Crater or Meridiani Planum » 2004-02-01 17:58:08

What daring photo-probe mission into Mariner Valley?
   What have I been missing and why wasn't I informed?

:laugh:  The one that hasn't been thought up yet. The one that some daring businessman is going to implement and make a bundle on. Just think, a massive volume of high-res, gorgeous photos from ground level, or perhaps a low-flying device which could fly continuously from hundreds of feet off the ground, snapping constantly while transmitting back to Earth. I'd purchase a book like that! Mars will sell!!

Ansel Adams on Mars... Oh Yeah!!

#34 Re: Unmanned probes » Which Mars site has you more interested? - Gusev Crater or Meridiani Planum » 2004-01-30 16:16:39

Meridiani... The anticipation of looking out over the lip of that crater is killing me. I'm also interested in that daring mission to drop a photo-probe into Valles Marineris... That's the one I want to see!! No really, a purely photographic mission I think would go over real well with the general public. Vistas! Cliffs miles high!! Can you imagine?!! Just imagine what Olympus Mons looks like from its' base?! I'm all for geology and science, absolutely 100%. But the general public, I think, wants to see incredible, vast, vistas. Mars tourism can only be kick started through pretty, jaw-dropping pictures.

#35 Re: Unmanned probes » Spirit & Opportunity 2 - Continued from original thread » 2004-01-25 10:42:53

About the 'Magic Carpet' material, just a thought but taking into account the temperature (very cold), and consistency of the powdery, grainy surface (like someone elses analog of moon dirt), including the possibility of subtle amounts of moisture, plus the very low atmospheric pressure - what comes to mind is... hard 'ice cream'. Think about it for a second...Take a scoop and try to make a dent in the surface....nada...., but scrape the surface and what do ya got?

MAGIC CARPET...!!!

Martian Vanilla anyone?

P.S.:  I like your ID name; gave me a chuckle.

Thanks ecrasez. I like it's many layers of meaning... 'Just add water', 'Martian Soup', 'Saucy poster', 'Obvious Mariner reference', 'My favourite Canyon - Valles Marineris', ' My favourite dipping sauce - Maranara(sp.)'.
:;):

#37 Re: Unmanned probes » Danger Will Robinson! - Spirit has gone quiet... » 2004-01-24 13:42:15

Interesting. What kind of equipment are we talking here? What are the simplest, cheapest equipment requirements needed to control a Mars rover 100 million miles away? Or, what kind of access would you need if you couldn't do it with 'homemade' items?

#38 Re: Unmanned probes » Spirit & Opportunity 2 - Continued from original thread » 2004-01-24 12:50:17

Okay, I may have posted this in the wrong spot ( under 'Danger Will Robinson' ) but:

Is it possible for someone to 'hack' Spirit or Opportunity? This may sound ridiculous, I know, but I'm curious to know if some savvy techy guy somewhere might be able to affect the rovers given the right hardware and ability, etc, at his disposal? Could Spirit have been sabotaged? From what I've gathered on the reports, there is a very strong possibility of software corruption which explains the weird behaviour, etc, but have JPL programmers plugged some form of defense mechanism against 'outside' intrusion? Would it be that difficult to do? Also, there is still a possibility of hardware malfunction - which would obviously render human interference improbable. But, is software tampering from elsewhere POSSIBLE? One has to consider ALL possibilities...
???
