Five new HiRISE images at Primary Science Phase Images, 2007 March 14, Release 17.

Dunes and Polygons in Olympia Undae is a good one for the convex/concave lighting-direction illusion. (Concave, east-west dunes within north-south dunes -- but they sure look convex, like... loosely stuffed sausages.)

What's the latest news on the problem with the two instruments on Mars Reconnaissance Orbiter? It hasn't been fixed yet, right? Do the technicians at NASA know what is wrong and how to fix it or are they just as confused as they were when the problem arose?

Did you read the post above yours and the article it referenced? Or are there new problems?

Or are you just seeking an update since then? I haven't seen one. Anyone else?

Ups. I didn't notice that was what Kullat Nunu linked to. Didn't MRO have two problems? I recall it had. Is the other problem solved? I believe it occured around the same time as the problem with the HiRiSE camera occured.

I don't recall a second type of problem. The HiRISE camera (HiRISE Instrument page) had problems with two detectors, two of the 14 CCD modules. It was a case of one being bad, then another going bad, and 5 more showing beginning symptoms.

Yeah, that might have been it. Has it been repaired or is it the same?

BTW regarding HiRiSE, quoting from Kullat Nunu's link:

I'm not sure what they mean by 'stabilised'. Is it back to the state it should be in or just that it has stopped getting worse? I would guess it is the latter, but not sure...

I think it's that the problem stopped growing and or spreading liked it seemed to be and the workarounds are working... around.

UnmannedSpaceflight topic: Spacecraft Set to Reach Milestone, Reports Technical Glitches

From a recent article, yesterday, from a purported (I should add: I have no reason to suspect not one) team member:

But, it's not a lot of information and answers, just a good collection of what is available.

How long will it take for HiRise to map the entire planet? I remember the area covered by one HiRise image was ludicrously small.

It's gotten to the point where careful investigation is needed just to tell parody from reality. I think that means reality is broken.- Noclevername.

It never will - a big HiRISE image is something like 6km wide and 12km tall - 72 sq km at 30cm/pixel (an 800 Mpixel image)

Mars is 145 MILLION sq km of land. >2 million HiRISE images would be needed. For comparison, in its near 10 year life, MGS's MOC2 camera took about 10% of that number, at 1/6th of the resolution.

It is hoped that CTX - the 6m/pixel context camera on MRO - will complete global mapping.

A little woo wooish question, but I bet everybody wants to know this as well. When is MRO going to look at at the infamous Face of Mars?

MRO will (or have) solicit imaging suggestions from the public. I've heard Hoagland on some radio show exhorting his cult followers to swamp the request facility with Cydonia suggestions when it opens.

I wish they'd ignore them. But they'll probably get around to it eventually. I'd wager it has not been scheduled yet, and more scientifically desirable targets still fill the queue.

Oh, yesterday, it looks, they may have announced how to make requests.

NASA Quest HiRISE:

Now, that's different that what I envisioned and maybe Hoagland, too. They are making you aim for certain goals, like this time water. That may slow down the ballot-box stuffers.

On second look, that appears to be a one-time deal. NASA Quest presents several challenges each year to students, and this HiRISE targeting is just one instance.

At the HiRISE site, The People's Camera has this goal:

Best I can tell, there is no such suggestion mechanism yet in place. (And, the NASA Quest challenge cited above is but one facet.)

When they do, if they're smart, they'll just include a filter that autotrashes "face on mars" and "cydonia!!!!" resquests, and get around to that imaging task when it makes scientific sense.

Well - from a scientific perspective, the FOM region doesn't present much interest. From a publicity perspective, it always has and always will. The recent MEX observation was the first MEX news to make it to the main stream media in months. If it takes one observation from HiRISE to help raise public awareness of MRO, HiRISE and space exploration in general, I'm all for it.

I confidently expect, that when a HiRISE image comes down of a totally natural, totally ordinary, totally unspectacular hill - Hoaxland will still say "face it, it's a face" and highlight dozens of artifact that don't even exist, right at the limit of the HiRISE resolution. His entire career depends on it. It's utterly impossible for him to change his opinion on the FOM now, his life has been dedicated to it, no matter WHAT evidence comes back from MRO ( not just from HiRISE, but CTX and CRISM ), he has to maintain it's a face, otherwise he has to loose so much face himself, his career would vanish infront of him.

Doug

Well, is the hoax community for the Face of Mars that big anyways? My initial guess is that there have been many people believing in some hoaxes around the Face of Mars, but comparing the number of people believing in Face of Mars hoaxes and Moon landing hoaxes, i would say Face of Mars hoax theories are more or less totally eliminated with the images taken after the first image.

Was it only because of the old school cameraes that we saw the Face of Mars as a face, or does it also has to do with the angle, shadows, aso.?

At what resolution do we have Mars covered in and what percentages? I mean, can you come up with a small list saying approx. how much of Mars we have covered with what resolution?

"The world is a fine place and worth fighting for." (Ernest Hemmingway)

To be honest, I'm not sure - I'm sure google would answer most of those questions...ball park figures though...

HRSC on MEX has about half the planet covered in 3d, at between 10 and 40m/pixel

THEMIS on Odyssey has done the whole planet in IR at 100m/pixel, and most of it at 18m/pixel in the visible.

Doug

Didn't find anything on Wiki, but i didn't look that closely honorstly Thx for the info though.
