Any doubts about cleaning Opportunity's solar panels?

See this picture:

We know rocks like this from Opportunity's pictures. But this one was captured by Spirit and yes, it is layered!

Stu, outcrops or not, these new images are really amazing. At last they look like rendered PR images from the mission web pages smile.

(Tried several times to access that "wow" link, it froze every time. What was it? Anyone manage to see the page?)

I do. It's a mosaic of microscopic images from Opportunity. Nice.

The movie is really stunning. That's what I call 'a comprehensive summary' smile. I would appreciate better resolution though.

This problem is pointless. Guys, you are not looking at SCIENTIFIC pictures. You are looking at pictures released for publicity. Normal people don't care for a science, they just want to see nice images of Martian landscape.
All in all the raw images sky is affected by a mere noise - those pixels in the sky mean nothing. You can just erase them and you lose no valid information.
Also, as you can find, not ALL pics have been edited in this way and many of them have originally illuminated sky. The only question now is its color. Should it be blue or reddish? Hmm, the pictures made by amateurs look damn good. But I would rather believe experts from NASA. Not because they would be smarter, but simply because they perfectly know their own MER-onboard hardware...

#8 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-04-06 03:39:45

But you must consider this fact: Some parts of Mars surface may have been rised by tectonics (etc.). Don't forget that even Himalay on the Earth has tracks of an ancient sea and we don't think that this sea was once 18kms deep...

#9 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-25 04:47:48

Do you know what confuses me? What was first - the Eagle crater or water in the same location?
If the crater then water (sea) could'nt be there too long. The crater would be probably much more eroded (just like craters on Earth).
If water then how can it be possible that we can see almost intact outcrop with clear water engravings on it? The impact, which would create the crater later, would crush and melt it down.

Let's hope that Spirit will make it to the Columbia Hills to find some better evidences!

#11 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-12 01:51:16

Ok, you have seen the heatshield. Now look at the parachute:

#12 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-11 06:55:27

Anyway, the new position of Spirit calls for a new fullres panorama.

#13 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-11 06:33:36

The crater IS interesting, but I have always been looking forward to the hills.

#14 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-11 02:24:46

Ok! We peer into the crater!

And we can see... we can see... nothing? Yes, Boneville is empty, no outcrops, no cliffs.

Magnificent view anyway!

#15 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-10 01:47:52

I can't be sure about that (the picture comes with no caption) but I think this newest Spirits's pic shows the far rim of Boneville with the fallen heat shield!!! wow!

Rxke: Opportunity's view of a nearby crater is not generated. You may find it also in the raw images on rovers homepage (in B&W of course).

#17 Re: Unmanned probes » Nothing special inside BB!? » 2004-02-26 05:25:33

No, this image is the sharpest possible.
Tha darker marks inside the BB are really scratches made with RAT. More information with an explaining picture here:

I guess, that a necklace made of these beads would be currently the most expensive jewel in the world smile.

#20 Re: Unmanned probes » Spirit & Opportunity *3* - ...continued from previous threads » 2004-02-11 02:01:55

1smlstp: There's nothing special about getting those images. I read a notice on MER's website about the shell so I browsed through Opportunity's raw images. The raw images (as you probably know) are available for everyone on MER's website. It takes some time for NASA specialist to create 'official' images from the raw ones - and the official images (usually much better in quality) are presented on a nearest press conference. That's it.
Also there is one more aspect: I live in Europe. So, while you sleep, I can browse on Internet and post pics smile.

#21 Re: Unmanned probes » Spirit & Opportunity *3* - ...continued from previous threads » 2004-02-09 03:56:23

Yes, this image is quite convincing! You are probably right.

#23 Re: Unmanned probes » Spirit & Opportunity *3* - ...continued from previous threads » 2004-02-09 02:56:42

1smlstp, another option is that the spherical object in the pic could have just fallen down the slope above the outcrop and left stuck in the crevice.

This is an interesting image:

It shows a landscape out of the crater which wasn't visible from the lander. Also on the horizon and in the leftmost part of the pic you can see two objects: dark and bright. They are believed to be the lander's heat shell and parachute.

#24 Re: Unmanned probes » Huygens Probe to Titan » 2004-02-06 01:48:35

To brthrjon: The communication issue was related to (quite embarassingly) omitted doppler effect. It's been decided to postpone Huygens separation and descent by several months, so the descent is planned for another orbit around Saturn. This will result in a better position of Cassini and descending Huygens thereby reducing speed difference between them and doppler effect as well.

#25 Re: Unmanned probes » Huygens Probe to Titan » 2004-02-06 01:36:33

To Atitarev: Both reasons. I understand they are worried about possibility of nuclear risks during start.
However I have already read something about initiative 'Don't spoil Mars with atoms!' (or similar). What can a reasonable man answer to this stupid hysteria? Rather do nothing but send the 'disastrous' atoms to Mars! smile
