As previously reported, there's a great lineup of speakers at the BAA out of London meeting on September 3rd - including MER Principle Investigator Steve Squyres.
Steve has kindly offered some of his time so that we can meet up and do a Q'n'A based on questions submitted by you lot. Obviously - there will be loads and loads of questions you want to ask and only so much time in which to ask them - however - I'll do what I can to pick as many of the best as I can squeeze in in the time available. There will be a write up here, obviously, and I will try and record it as an MP3 and post that here as well. Steve's book 'Roving Mars: Spirit, Opportunity and the Exploration of the Red Planet' is published next week - and a signed copy will be winging its way to the person submitting the best question! * If you have questions you want me to pitch to Steve, then drop me an email to doug@rlproject.com with the subject SS Q&A As a heads up - please take note of the other speakers at the BAA meeting - and if you have specific questions you'd like asked of them - I'll do my best to try and get them in after their presentations at the meeting. The last two ( Profs Greeley and Muller ) are on the Sunday and the Friday respectively, but I will be trying to get down to those presentations as well - but no promises. -Prof. Carolyn Porco, Principal investigator, Cassini imaging system -Prof. John Zarnecki, Principal investigator, Huygens surface science -Prof. Mike A'Hearn, Principal Investigator, Deep Impact, -Prof. Ron Greeley, Scientist on several planetary missions, Chairman of NASA & NAS Mars exploration panel -Prof. Jan-Peter Muller, Scientist on Mars Express hi-resolution camera team, University College London. Doug * 'best' to be picked by SS and myself on the day |

It's not been too easy finding where he will be on his signing tour, but he'll apparently be at KSC on August 9th. Has anyone found the schedule?
http://www.kennedyspacecenter.com/eventsDe...?calendarId=192 Doug: I've sent you my questions. I'm curious how many others you've received. Do you have more questions than you could possibly ask? -------------------- ...Tom

Darn it. I should have kept my mouth shut. My question would have had a 50% chance of winning the contest.
On second thought, I sent you two questions. If you were counting both of those, I pretty much had the odds locked up in my favor. Now I really hate my big mouth. Seriously, though, I hope you've gotten more questions by now. This is a precious opportunity and we should collectively make the most of it. -------------------- ...Tom

Yesterday I was tempted to call for questions elsewhere, but then I thought no - it's the people here who I want to get the benefit from this. When the article and recording is done, I can post THAT elsewhere and say "if you did something about your conspiracist kooks, you guys could have asked him stuff as well"

Great initiative Doug! Amazing how this place has grown.
Unfortunately, I don't think I know enough about the MERs to have a question ready. I only look at the general progress and the pretty pictures posted here |

QUOTE (deglr6328 @ Aug 2 2005, 11:54 PM) So what actually happened? I can't figure out either from the review or the correction, and I can't seem to find any other useful commentary on this particular row. What did the original message say, and why did Porco's co-lead object to it? [I have got to say that I would probably have objected to there being a message at all, as it seems to me to be a waste of space. The spacecraft itself is a far better (and more interesting) time capsule than anything they could put on a disk; and if our descendants a century or two from now come across it, they are unlikely to find anything on the disk particularly informative or interesting. And I don't think there's going to be anyone else who will get to Saturn before we humans do.] |

How about: "When you are looking at the latest images of a new and unseen part of Mars which was of course beamed back to us from the rovers you helped create, do you ever think of what your teacher Carl Sagan might say if he were there to ponder them with you? Do you feel that you have honoured his memory with your achievement?"

deglr6328, that's a beautiful question...
I've tried to imagine that myself, Steve, after-hours, one of the 'scenic' pics on the big screen, computers humming... Sitting there alone for a minute, before the rest of the crew comes in... Thinking of Carl.... Question: given that current scenarios talk about 500-ish days manned missions, and the rovers being able to function for that long... Has this changed the feelings re: feasibility of such stuff? The fact that the rovers keep functioning, does that mean we finally 'got it' how to do things there? That we're able to build stuff that lasts an arbitrary amount of time? |

How about these:
Ignoring latitude restrictions, elevation restrictions and terrain restrictions imposed by EDL, if you could put a third MER rover anywhere on Mars, where would you put it and why? Apart from the water story uncovered by Opportunity, which one discovery about Mars made by the MER rovers do you find to be the most scientifically compelling? |

Similar to SFJCody's first question:
* Given that it's been harder for Spirit to come up with evidence of past water, have you wished one of the alternate landing sites had been picked instead? Not a valid question, really, since without Spirit going there we wouldn't know what we know now. I'm glad Spirit put down in Gusev - it's a very interesting and photogenic place. And we may not have had all of those cool dust devil movies! -------------------- --O'Dave

Will Squyres lead as main scientist for the present MER project as the MSL project?
I like the SFJCody and Olave questions about the 3rd MER. I think there is a 3rd MER in the laboratory and would like to ask him if this 3rd MER will be sent to Mars soon? Rodolfo |

Good thing I blew out of work early - Steve Squyres was on NPR's Science Friday this afternoon, along with Richard Zurek talking about MRO, *and* Mike Brown talking about 2003 UB313.
I missed Mike Brown and the first five minutes of the interview with Steve. Good show though, the audio should be archived for download after 6:00pm ET. -------------------- --O'Dave

Talking about the book...it looks like it is Part I (or: the making of...)
will there be a part II (science results)?. Both rovers are still functioning, so that might take a while... |

Ok, some Q's for the great Steve
1. IF one or both rovers will manage to reach SOL 1000 will there be any S1k bug in the software? And if so, is it being worked on? 2. Do you follow the different Mars/MER communitys on the Internet and what do you think about the general interest in the MER mission after such a long time? Would be interesting to know the answer to the second one -------------------- "I want to make as many people as possible feel like they are part of this adventure.

Thanks for the link to that audio, odave. It was an interesting interview with SS, despite a few party-crashers and other clueless people that called in. They were quickly dispatched by the adept host. Too bad some of us didn't manage to call in. Fortunately, Doug has provided this access to Steve's ear. There are not likely to be any bad questions here.
I thought I had a fair chance with the questions I sent in, but there have been some really good questions proposed. I paticularly like the ones about alternate MER landing sites, but I can't help but think that deglr6328 trumped everyone with his question about Carl Sagan. I can't help but take a shot at an answer to SFJCody's alternate landing site question. Besides, it will give us something to discuss while we await Steve Squyres' answers to the questions Doug asks him. If I didn't have to worry about the survival of the mission during EDL, I'd toss a MER into the bottom of Valles Marineris. It seems that would be a pretty good place to find signs of water, or at least groundwater. There might even be some springs down there. -------------------- ...Tom

It just occurred to me that since I sent Doug my questions via the email address he posted, they were not publically posted. Since we are discussing the submitted questions, perhaps I should post my two questions here.
Opportunity Question Many people in the UnmannedSpaceflight forum see the Etched Terrain as a wasteland that Opportunity needs to pass through on the way to Victoria Crater. Some of us believe the Etched Terrain will be a treasure trove of science targets that will perhaps keep Opportunity busy for the rest of its already amazing life. Now that you are seeing the Etched Terrain through the rover's eyes, what are your thoughts on this new terrain? Specifically: • What different kinds geologic investigations do you hope to perform there that can't be performed in impact crater exposures? and • What do you expect the topography to be like as Opportunity heads further into this terrain? Spirit Question The fascinating rock textures and geochemistry we have observed as Spirit has trekked upward in the Columbia Hills have fascinated many of us. Do you have enough data to confidently determine if the rocks were created by volcanic or impact processes, and if so, which would that be. -------------------- ...Tom

I´m not too confident my question about money & future missions will cut the grade amongst the many experts chipping in here. (Although I am not a "beancounter", honest!).
But my ten cents: I feel that the continuous presence of daily live data from Mars, near enough anyway, have substantially enlarged my world. What CNN did in the past to bring the world news into every house so to speak, did Steve & his team in making Mars a permanent feature in my daily news uptake. I watch less "old fashioned" TV these days, much less in fact, and instead I check the latest from Mars, Titan, various comets, and more. Not to mention the continuous pushing of the technology envelope whilst thinking about new opportunities & challenges for solar system exploration. Think about it... our lives have been enriched tremendously. Thus for me the big thing is: is how can we make the daily news from Mars a permanent thing? 3 Cheers for Steve! |

Harder, you are the first (I don't want to violate your copyright/priority ), but this is very close to the question I would like to ask!
Also my life has been enriched tremendously, thanks to the wide, fast data availability from this successful mission (thanks, NASA!)... So, in order to make this live-update permanent, why not to send within few years a half dozen MER rovers in other exiciting places? (eg inside Valles Marineris...). I know, NASA has other plans (MSL or sample return mission), but the opportunity to capitalize a such tremendously successful space technology is really exciting! I didn't make figures, but I immagine that sending 4 new MER rovers (with only minor improvements over original design) would cost like sending fist two and, for sure, probability of success is high, contrary to the new planned missions like MSL which will use innovative but risky technology. I know, this "soviet"-like approach may appear conservative, but I'm convinced is the best way to widen sampling of Mars geology while keeping excited audience on Earth... -------------------- I always think before posting! - Marco -

For Steve: "Have you ever browsed the unmannedspaceflight.com bulletin board and seen some of the amazing imagery interpretations done by its members?" I guess this is like asking the Rolling Stones if they ever visit their fan websites!

My humble offerings - more project based than science I think:
1. How do you see the current anti-intellectual political climate in the United States affecting future “big science” projects like planetary missions? As one of the most public science figures today, have you encountered any of this opposition in your travels? 2. MER has been quite successful in terms of balancing public relations and real science. Do you find that others share your zeal for public outreach? Do you think this will be the standard for future planetary missions - a policy of near real time access to imagery? Or is this something unique to the team assembled for this project? 3. Has the team considered any long term “hacks” of the rovers in order to continue to do science? Or would these only be considered as needed? If mobility goes first, are there contingency plans for seasonal site observations, or even something "crazy-go-nuts" like a full MI panorama of the entire area accessible by the arm? -------------------- Lyford Rome

Doug
A couple of questions for Steve 1) Does he see any value in farming out research to this or other mars forums' enthusiasts, I can't imagine 100,000 images could be adequately evaluated by such a small team at JPL. e.g looking for certain rock types / distributions / clouds in images 2) Any possibility of a competition ( say schools / colleges / Mars Forums ) the prize being to 'Drive' one of the rovers on mars Regards Brian |

I've got a couple of questions that are really variations on a theme. If I were clever, I could think of a way to phrase them as one question, but I'm not feeling clever today.
Given the constraints of money and mass, would you fly the same instrument package again? If not, what would you fly? And related to that one: If you could add one more instrument (or maybe, a tightly coupled suite of instruments) to the MER package, what would it be? Operationally: what would you do differently if you had to do it all over again? I'm especially curious to know what's tops on the "definitely wouldn't do it again" and "should have done it from the beginning" lists. |

From a dribble - it's turned into a waterfall of good questions. Lots of duplication, and lots that I wanted to ask anyway - but I'll start collating them soon into an order
To give myself time to make sure I can sort thru all this lot - the submission 'launch window' will close on August 21st Doug |

Come on guys! Haven't seen any activity here in a while, and there's less than a week left! My question to steve would be how suprised is he that the rovers have lasted this long, and how long did he expect the rovers to last. Obviously, the "warranty" was 90 sols. I remember reading an article before launch from one of the MER team members saying they were fairly confident they could get 4 months out of the rovers.

May I suggest that it NOT be a question to ask Dr. Squyres?

I want to ask him what it is like to be PI of the most succesfull scientific operation on Mars ever
And if he feels that he could have done any better And what he would do differently on the next assignment, assuming he'll be in a similar position on a next project, investigating the surface of another world. |

QUOTE (ljk4-1 @ Aug 16 2005, 10:15 AM) May I suggest that it NOT be a question to ask Dr. Squyres? I get the feeling he has now been asked for his views/feelings/thoughts on the surprising longevity of the MERs about as much as the Apollo astronauts have been asked about what it was like to walk on the Moon. I would ask him if he could place two more rovers on Mars, where would he like to put them? True eough, but I would like to get his perspective without any possibility of having to "eat crow", so to say. Early on, of course the only figure quoted is going to be the 90 sols figure. Now, with this mission being classified as a huge success regardless of what happens tomorrow, I wonder if he would be more forthcoming of his original expections of accomplishments and longevity. |

Then go and buy his book... Squyres is very forthcoming in his book about his expectations; he was so tied in to the 90-sol projection that he got a bit, um, shall we say "high strung" whenever anything threatened to steal away even a single sol from the exploration program. He also said he was rather expecting Spirit to be on its very last legs by the time it reached the Columbia Hills.
He talks about getting more and more relaxed about things as time went on and it became apparent that the rovers weren't going to die anytime soon. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

I'm curious about the strategy behind building ever-more complex spacecraft. Given the high cost of creating new designs, what do we give up by, say, making "n" more rovers just like the current crop and sending them different places?
I guess my question nets out to the question of wider surface coverage vs. new types of data. |

Given the high cost of creating new designs, what do we give up by, say, making "n" more rovers just like the current crop and sending them different places? Compare the science output of MPF with MER, and you know that technological renewal of spacecraft is important. I understand what you mean, because the output of MER we see now is absolutely astonishing and it would be great to see, let's say, 4 other sites with clones of Spirit and Oppy. But: We need to move on. Considering the landing tech. (airbags) of MER, only a couple of % of the Martian surface can be reached (flat, low, near the equator). What we want now, is look somewhere else, and we want to look for other things. Higher latitudes, other kinds of terrain, maybe even polar regions. Also we want to follow the carbon (besides the water). And therefore we need a whole bunch of new things that can't be integrated in MER. RTG's, chromatographic columns, spectrographs, lasers, high def. video, maybe even a skycrane (or 2). Et voila: a whole new design is needed. But believe me: We will absolutely not believe our eyes after MSL landed. It will be the same giant leap from MER to MSL, as it was from MPF to MER. I can't wait. PS: Another thought that adds up to it: The MER design isn't gone. It worked out as a great design and it learned a lot of people a lot of things. This knowledge is "in the pocket" and lot's of aspects will be used in new designs. It is not just sci. research on another planet, it is learning how to get there, how to squeeze out the optimum output of the project (people, limited amount of sols, route, etc.) AND, how to use this experience in making the next one even better. People will never stop to improve technology. |

Steve Squyres mentions in his book an early plan for the mars rover to be used as a sample collector for a later sample return mission. Spirit has seen such a variety of rocks and soil in the Colunbia Hills, I wonder which 3 or 4 sites would be highest on the list for sample return if Spirit was collecting samples.

I just realized that the deadline is August 21, so I will submit these questions prior to reading his book. These are the questions I would ask Steve over a pint:
1. What has he learned or seen from the MER that most surprised/shocked him? 2. What issue/question caused the most heated debate among the MER team and how was that issue resolved? (possible follow up: did the MER team have a similar debate as seen on this forum about whether Spirit should stop for "boring science stuff" while going up Husband Hill versus "put the metal to the petal" to see if more promising science targets were found on the other side?) 3. Which is his favorite rover and why? 4. What date does he predict humans will set foot on mars? What will be the vintage of the first wine made from grapes grown on Mars? 5. Any chance for a rover expedition to Titan? 6. Has there been any scientific (as opposed to PR) benefit from posting the raw data from MER so quickly on the internet -- have observations/analysis from the amateur community had any impact on the science conducted by the MER? Stated alternatively, is there any benefit he would tell to ESA of disseminating information rapidly to the public, aside from the PR aspects. Alternatively again, is there a down side to doing so? If so, what? 7. Does he still hope to find lacustrine materials in Gusev crater? If so, where does he think is the most likely place to find it? 8. How do the original space-based observations of Hematite at Meridiani compare with what was actually found on the ground and what does that tell us about Meridiani? I will leave it at that! |

I hate to be a bit complainy or something, but I keep wondering just why the Pancam near-infrared images are clearly not in good focus... as you step through filters to longer and longer wavelengths, the pictures get noticeably less and less sharp.

It's a wavelength thing. The longer wavelengths of IR result in lower resolution. If you want the finest details visible to human eyes, go for L7 or R1. That said, there are some things the human eye cannot see. To "see" them, use the IR filters. The pancams are amazing instuments.

I'd have to check pre-mission camera technical design stuff, probably published in Space Science Reviews or some such place.. That's where they often published that stuff before. I'd be surprised if the cameras were diffraction limited at longer wavelengths.. They aren't super telephotos and have much larger apertures than human eyes.. or am I missing some info?

QUOTE (edstrick @ Aug 21 2005, 07:37 AM) This comment from the Bell document probably gives a hint: QUOTE The approach for such a panorama will be to acquire red filter images at full resolution in both eyes,along with green and blue filter images at reduced resolution (using compression and/or downsampling) in the left eye. Such a panorama provides morphologic and textural information at the highest possible resolution, ‘‘true color’’ information at somewhat lower resolution, and good stereo ranging of the full scene around the rover. That's for full panoramas obviously but I think the same type of strategy is used for most imaging. The highest quality imaging is done with one filter, additional images are for geological science data\context\colorizing and don't need to have the same resolution so they are downsampled. I don't think it's wavelength dependant it's a planning decision that maximises the science data returned. |

That was done way back for the mission success pans for both rovers - the L2's were full size, the L5's and L6's were half res. But that's when they were unsure about UHF performance and only doing 32kbps. Now that they do 128 or 256kbps they can forgo that data-saving tactic. I think it's just that things are not quite as sharp in the near IR perhaps? Doug |

I do not claim to be an expert in the area of optics and imagery, but am pretty sure I learned that image resolution was inversely proportional to wavelength in physics. Angular resolution = wavelenth divided by the diameter of the objective lens. Since blue light has a shorter wavelength than infrared, it should result in images with higher resolution...and that is what we see from the pancam filters. I did some quick research on the web to see if I could find some examples to support my argument. Here is one example of longer wavelength IR images with lower resolution than similar images taken in visible (shorter) wavelengths. http://www.afrlhorizons.com/Briefs/Feb04/DE0303.html They say, "The two images shown in Figure 2 are from the AMOS 3.67 m telescope using infrared light. They have lower resolution than the visible-light images because infrared wavelengths are much longer than the wavelength of visible light. Telescope resolution is directly related to the wavelength of light, the mirror diameter, the mount stability, and atmospheric turbulence effects." I think those images of the Space Shuttle show the affect on an object we are all familiar with. Is that not the same difference we see between the L7s and the longer wavelength filters on the pancams? This could make an interesting thread in the imagery and tech area... Some of the people who are really knowledgeable in this area might miss this discussion here. -------------------- ...Tom

Cosmic Rocker quotes: They say, "The two images shown in Figure 2 are from the AMOS 3.67 m telescope using infrared light. They have lower resolution than the visible-light images because infrared wavelengths are much longer than the wavelength of visible light. Telescope resolution is directly related to the wavelength of light, the mirror diameter, the mount stability, and atmospheric turbulence effects."
BUT.... the AFRL images are THERMAL infrared with a wavelength probably near 10 micrometers, not Near-Infrared, with a wavelength of around one micrometer.. which is twice the wavelength (0.55 micrometer) of yellow-green light (the wavelength of visual maximum sensativity) Resolution is diffraction limited only if the image on the sensor is diffraction limited AND the sensor samples the image with a pixel spacing finer than the diffraction limit. Often, Imaging is not diffraction limited, but has other engineering constraints. Many camcorders have tiny (cheap) CCD detectors. They can take decent images, but have fewer square micrometers of area per pixel, are less sensative, and most importantly, can hold fewer electrons.. and "fill up" faster and saturate sooner, resulting in either lower-signal-to-noise-ratio or overexposed images. One possibility, I'm not a silicon chip optics expert at all.. is the silicon of the CCD may be so transparent at 1 micrometer that there's "bleeding" of the image between pixels due to sheer transparancy of the chip at near-IR wavelengths. |

Oh, there was a deadline. Well I'll add these questions anyhow:
1. Since solar panel performance has been so much better when the rovers are parked at an angle (eg. Opportunity in Endurance), was powered tilting of the rover body with the rocker-bogey system ever considered as an addition to the mobility system? 2. Do you have nicknames for the rovers, like Oppy for Opportunity as used by the web forum community? -------------------- Antti Kuosmanen

Don't forget that the pancams use lenses (as opposed to mirrors), and therefore have chromatic abberation. I always assumed that that was the cause of the fuzzy IR images.

Today - my copy and the best-question-prize copy arrived from the US - and actually -it's a very 'nice' book - nice paper, binding etc. A scrawl from SS will look good on there The best question I've seen asked is regarding using different filters in L and R simultaniously to get pseudo colour of the dust devils - but there's some nice ones in here.

The discussion about image resolution jogged my memory about the discussions I had with Jim Bell way back in October 2003 when the MER teams were doing their first real rehearsals. He was helping us figure out the best set of images we could get of the Red Rover Goes to Mars DVD within the smallest bandwidth footprint. Originally the planned sequence included L256R2, approximate color plus stereo. (The stereo was in there because the "Astrobot" at the center of the disk was once a lovely machined 3D LEGO astronaut, but due to requirements from NASA HQ the poor Astrobots were flattened into stickers.)
Anyway, when we got the test set of images back the Astrobot had disappeared from both the L2 and R2 images -- turns out the flight-qualified label material we used was transparent at 750 nanometers! Fortunately, Jim was able to get some different filter choices substituted into the final sequence. One of his suggestions is appropriate to this discussion: "I would like to replace R2 with L1 (empty), which gives the highest resolution image detail in Pancam images. We will use a lower amount of compression for this filter to maximize image detail. The compression level will be set so that the total data volume for the new version of this sequence does not exceed the data volume of the existing version." In other words, as helvick pointed out, it's likely that in each image sequence from the rovers, one or two -- most commonly L2 and R2, and occasionally the L456 if they are planning on making a particularly lovely press product -- are sent with lower compression. The rest, which are taken only for color information, are sent with higher compression rates -- not necessarily subsampled (though that would be another way to do it), just compressed more. When they were writing the sequences in ops during the mission they usually talked about compression rates of 8:1 vs 20:1, stuff like that, though I'm not sure if I'm remembering the exact choices of ratios correctly. This is particularly true for full 14-filter sequences that go all the way out into the infrared. A full multispectral stack of images contains in it a LOT of redundant information -- areas in light and shadow are lighter and shadowed in every image in the stack. They reduce the redundancy by compressing many of the images that are there just for spectral info at a higher rate. (Writing that down, I wonder why they don't consider ratioing the R3-7 bands with the R2 band before sending the data to Earth -- that would cut down on the redundancy. Hmm.) --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Arhgh - those codes on the DVD's had Helen and I going nuts
You got a good deal mind you - as the Spirit one was imaged twice I think... Sol 2 - You got a REALLY sharp L4, highly compressed L5, a 2:1 downsampled L6, and a nice L1. If you make a colour image from the L456 - then overlay it onto the L1 - you get great results. Bog standard L456 http://www.unmannedspaceflight.com/doug_im...pir_dvd_456.jpg L456 as colour over L1 http://www.unmannedspaceflight.com/doug_im...r_dvd_456x1.jpg L456 and L1 stretched a bit - and multiplied http://www.unmannedspaceflight.com/doug_im...dvd_456x1xD.jpg One problem is that it's just short of being in focus - it's a bit too close to the pancam. However - sol 37 comes along and we get L24567R2 - all full res and with mild compression The 456 comes out as http://www.unmannedspaceflight.com/doug_im...r_dvd_2_456.jpg and an L2/R2 anaglyph http://www.unmannedspaceflight.com/doug_im...r_dvd_2_ana.jpg Meanwhile, on the other side of the planet Full sized L1 and L4, but this time downsized on both L5 and L6 L456 http://www.unmannedspaceflight.com/doug_im...opp_dvd_456.jpg L456 x 1 http://www.unmannedspaceflight.com/doug_im...p_dvd_456x1.jpg L456 x 1 with tweaking http://www.unmannedspaceflight.com/doug_im...dvd_456x1xD.jpg Sol 12 - Oppy got another shot http://www.unmannedspaceflight.com/doug_im.../opp_dvd_12.jpg Sadly - in the part-taken L4,5,7 mosaic http://www.unmannedspaceflight.com/doug_im...nest_mosaic.jpg The DVD isnt there - it's off to one side. All this is on the Planetary Soc website - but it was fun to recreate it all myself as well - ahhh...sol's in single digits..those were the days That was a fun blast from the past. Doug |

Well - I can see why he might be nervous - certainly inside the 3m point at which Pancam gets nicely focused (hence the 2:1 downsizing of all the deck-pan selfportrait images ) - but if Jim says pancam will do X ...pancam will do X+1
I was amazed to find that those first few sols were using really slow UHF passes - no wonder they compressed-to-hell those first pancam octants. Pity that the media abandons such missions early on - as the success pans were the lowest quality of the lot Doug |

Thank you, edstrick, helvick, Emily, and Doug.
Well, I guess there is more to the resolution of pancam images than I realized. You folks clearly know more about the subject than I do. Thanks for taking the time to explain it to me. I must admit that I am still puzzled by the fact that the L7 and R1 full frames always appear to be the highest resolution to me, and the resolution appears to decline from there as the wavelength increases. I spent some time tonight looking at some pancams more carefully. Perhaps the longer wavelength ones only "appear" to be lower resolution. -------------------- ...Tom

However, you can (as long as they are within a certain distance range) focus on one or the other. Also, if you move one closer or farther away from you, you can focus on both at once. Of course, none of this applies if you have lousy eyesight. EDIT: Oops, I skipped over the part about the green LED when I read your post. What I said still applies, though--just group the green and red together (and count them as one). |

Really - you cant focus on the blue ones - your eye isnt clever enough to do 'different' focus on it because it's a different wavelength
Have all three lined up - the blue one just wont focus. It's very odd - I read it on the internet ( so it must be true ) and had a try myself and it's actually true Doug |

Well, provided your eyesight isn't as bad as mine. :-) The Pancam's focus at range(3m and out) should be close to perfect across all the filters, certainly more than good enough to yield images at their designed resolutions with all filters. |

QUOTE (djellison @ Aug 23 2005, 07:16 PM) Really - you cant focus on the blue ones - your eye isnt clever enough to do 'different' focus on it because it's a different wavelength Have all three lined up - the blue one just wont focus. It's very odd - I read it on the internet ( so it must be true ) and had a try myself and it's actually true Doug Hmmmm, I do believe this is not because the lens of the eye has trouble focusing the short wavelength, but is instead because your retina's concentration of blue sensitive cones is, well, crap compared to the green and red sensitive ones. Thus the spatial resolution in the blue is greatly reduced for the eye. Recently, this fact was verified at the UofR by imaging the retina microscopically,in vivo using adaptive optics. |

You *can* focus on the short wavelength image, but not at the same time as the red/green image. The eye does not have the option of mixing two refractive lenses with different chromatic abberation in order to cancel out chromatic abberation over the wavelength range it's sensative to. The short wavelengths, rarely the brightest thing in the visual field (other than the sky, which doesn't need acuity) tends to lose out in the focus contest.

Hi there!
I did an interview to Robert M. Manning (Chief Engineer for JPL's Mars Program Office) some months ago. Probably you´ll remember him as you see the picture: http://www.astroenlazador.com/mer/entrevis...g/interview.htm Probably this could be useful for you to think about new questions, etc. But I would be very grateful if you could ask one of them to Mr. Squyres: Spirit landed on a volcanic rock area and had to drive more than 3 Kilometers (1.86 miles) to find important clues to confirm the past presence of water on Mars. If this mission had consisted in a static lander, it would have been impossible to obtain that important scientific information. Do you think sending static landers to Mars is still worthwhile or reliable? (As you´ll suppose, I´m thinking about Phoenix Mission for 2007) Cheers! |

I doubt I'll have t'internet access whilst in Cambridge - I'm certainly not counting on it. The end result's going to be an MP3 of the q'n'a with Steve, and an article for Space Daily.
If I'm allowed, I'll record his (and everyone elses) talks at the conferences, but at lower quality ( Mini Disc recorder with a brilliant little microphone ) The names thing is something I did for Beagle 2 when I just had a little Beagle 2 Yahoo group. I did a Christmas Card the day before landing - and delivered it on Christmas eve....and we never heard from the lander again. So clearly, it was all my fault because I cursed the whole thing. Problem with some sort of pressie is that he's got to carry it all around with him, and back to the US on a plane. Dont worry - he knows about you lot and how greatful you are - one of the things I'm going to talk about is the paradigm shift created by putting the raw imagery out there daily, who thought of it, how it works, what it's achieved etc etc - BUT...if you want submit to a list, then I've made a new email address thankyousteve@gmail.com Put your real name, your forum name, and a single line of thanks - send it to that address , and I'll see if I can sort something out before heading off on Friday. No promises, but I'll see what I can do. Cut-off for that is mid-day Thursday GMT. (you've got 2 days ) Doug |

Right - my list of questions is all written - it's about 4 pages long - but I've put it into a few catagories.
Pre MER Spirit Science Opportunity Science Rover Tech and Rover Future Blue Sky and the Future ( not blue sky as in the sky on mars is blue - blue sky as in imaginative thinking ) Those who def. have quesitons in at the moment are... Me (qiute a few times ) Sunspot, Philip, Cosmicrocker, Tman, dvandorn, Cosmicrocker again, David Ellis, Ustrax, Philip again, akuo, Garybeau, Henric, DEChengst, dot.dk, GS Norgathon, George Purcell, Ron Jones, A.Spyros, SFJCody, Helvick, Avronperlmann, Mhoward, Marsman, degrlr6328, lyford, Philip again (wow, that's 3 - good questions Philip), Paxdan, remcook, and me again Of course I dont know how much time we'll have, and I dont know how much things will change with tonights press conference - but I'll do the best I can for everybody.

I wracked my brain trying to think of the right sort of token....none of the mosaics or panoramas that the MER team, or us lot have made are worth it really - he'll have seen them all.
Then I remembered two things. 1) SS is looking forward to MRO so he can see his rovers again. 2) He wants Bootprints in the wheeltracks at Eagle Crater ( read the book ) So I added together all the names I got - picked my favorite one-liner, but changed it a bit, and came out with this - which is printed as a 7 x 5 in a little frame There's also a matching, identical one, but it's the full resolution simulated imaged - like this - http://www.unmannedspaceflight.com/doug_images/purgatory.jpg and just Simulated view of.... at the top - so if he gets bored of the MRO simulated image, he can switch to the better view Doug |

Right - I'm signing off for now - if there's any net access while I'm in Cambridge, then Myself and Nico will check in with a report on the talks we get to see, and how the Steve interview went
If you're wondering where we are... http://www.britastro.org/news/items/2005008.html back on sunday night Doug |

Well - just got home.
It was a superb weekend - brief overview.... Met Nico ( Nix ) at Cambridge Station at about 1500 on Friday. First of all we parked in the Station car park, I walked into the station and couldnt find him. I went back to the car, got my UMSF badge, back into the station and Bingo - he comes over and says Hi Made a total hash of the Cambridge 1 way system but got to Fitzwilliam Halls - where we were staying for the weekend - settled in, found a nearby restaurent and enjoyed nice pasta! Then - walked to the Institute of Astronomy - and a slight change of schedule. Unfortunately, Ron Greeley's has had family issues w.r.t. Katrina, and thus is still in the US. He emailed his talk on MGS and MODY to Prof. Jan-Peter Muller who was actually due to give his MEX talk on Friday - but did an excellent job doing Ron's instead. Then, after the talk the conference organisers opened up two nearby observatories - one including a 12" Refractor ( the Northumberland instrument - famous for NOT discovering Neptune, but it's thought that it should have done ) - various feint fuzzies were looked at thru this and a 7" refractor next door. We retired to the kitchen of our accomodation for tea and muffins - Nico very kindly gave me an ENORMOUS print of a Bonneville pan ( it really it beautiful, and it may well live on our Dining room wall ) as a thanks for introducing him to the long, dark, spiral of dispair that is MER image stitching Helen retired ( very wisely ) to bed and Nico and I compared MER imaging notes till 2am Sat - the big day - breakfast at 8am - and a little minibus to the Cavendish Laboratory. ( http://en.wikipedia.org/wiki/Cavendish_Laboratory ) Whilst waiting for the first talk, we had a look around and infact saw the very cathode tube with which J J Thompson discovered the electron!! I'll skip the amateur observational talks - although they all contained astonishing imaging - and show that actually, observations of Jupiter by amaters with scopes as small as 9" are doing genuine science about Jovian storms (is there a relation between oval aspect ratio and their speed - YOU BET YOUR ASS THERE IS...sorry - you had to be there - the chap who gave that talk was...how can I put this...VERY american!!) Carolyn Porco's talk was, quite obviously, superb. Excellent imagery, some great movies of the shephard moons - many 'ooohs' and 'ahhhs' at some ring movies. Nothing that one could consider 'new science' - except some temperature values for southern Enceladus - the tiger stripes appear to be about 10K higher than the neigbouring terrain. I put my foot in it asking about the spokes - and they are currently not visible ( as we all know ) but they are considered to be a potential feature that will re-appear perhaps late next year as the solar angle increases. John Zarnecki's Huygens talk was superb - some superb slides that I will post in a more verbose review at a later date - all fantastic stuff. I spotted a double spike in the echo-reflection that I asked about during questions "Well spotted" said John...but it was actually an error in their interpretation of the data and isnt real. A good job that publishing in Science takes so long I spent lunch discussing orbital mechanics on a chalk board with Nico in the dining hall at the Cavendish Labs. I didnt say anything at the time, but on reflection, I wonder what scientific breakthru's have happened over coffee on those three blackboards - at arguably one of the greatest laboratorys in the world. Done with lunch - more observational talks, and then after more tea that was too hot to drink before the next talk started, Prof. Mike A'Hearn - the highlight of THAT talk being a potential identification of the crater from VERY processed high res data - deconvolution of which has recovered all the data ( so he said ) specifically because of the nuences of that specific design of telescope. And then...of course...Steve's talk. It was without doubt ( and I know I'm going to be biased ) the best of the weekend - even the event organisers agreed - not many pretty pictures in it, but he is without doubt the best speaker I've seen, very funny, informative, and un-waffling. Good science which I'll be writing much of about for my spacedaily article. We briefly met before his talk, just to confirm that I was recording it - but ONLY for my purposes of writing a review of all the invited speakers for the BAA journal - sorry guys, you cant have a listen - but if you are within travelling distance..ever..of a Steve talk....GO. Dont think about it..just GO. If it's your Grandparents Diamond wedding anniversary...forget it - just see Steve. And then...the big one. We had to leave the lab to conduct the Q'n'A, but leaving the lab you could see that Steve was excited just to visit the lab as whilst I was enjoying Mike's talk- he'd been up to see Thompson's Cathode Ray tube...we took to a park bench on the park beside the lab for the Q'n'A, for which he was happy to take as long as it took...45 minutes nearly Ustrax...I have your Raving Mars picture signed - but he hadnt heard of Ultreya - infact they dont have a name for the dune field yet. I didnt get thru all the questions, but I did get thru a lot - he was SO open and friendly and fun. I have a favorite question in mind, but I'm going to listen back to the Q'n'A before the final decision. Steve gave us so much time, Nico and I almost totally missed dinner. Helen asked one question which has arisen elsewhere before heading off for dinner... she asked why he refered to the rovers as 'she' - and he confirmed that they do, as they're vessels of exploration just like ships. Ever since - I've been thinking "I didnt ask him this...I didnt ask him that" - but the Q'n'A itself was as good as I could possibly imagined, Steve more friendly, enthusiastic and willing to answer questions than I could ever imagine...just...wow. Before the Q'nA I gave him the 7 x 5 and he was clearly genuinely touched - the effort was appreciated. Got back, amazingly the college kitchen had kept something aside for Nico and I, and then Nico gave up and went to bed, whilst Helen and I were back in the kitchen enjoying a movie by some people who went to Antarctica for an Eclipse. The penguins were better than the eclipse ( clouds ) - but it was a brilliant little video. Sunday morning - another killer 8am breakfast - and a talk by the Terrestrial Planets head of the French Astro Soc - excellent mars imaging from earth - and Prof Muller gave a cracking talk on MEX - and explained why ESA and MEX imagery is so slow....European Law. There is an excellent website out there that collates Earth based imagery from every asset you can imagine, and he and his team are desperately trying to do the same for Mars...they just need some cash. The will to spread the data is very much there, they really want to spread it about, but European law makes it quite difficult. So I'm going to see what I can do in terms of figuring out how we can make progres in this w.r.t. talking to local politicians. Then...BACK to the station...and much easier to find was Emily No badge required! Found somewhere not too bad for Lunch and spent a couple of hours putting the entire world of planetary exploration to rights - she's as friendly and knowledgeable a person as you could possibly want to meet. We discovered that we've had some similar thoughts regarding the whole Amateur imaging community, and we're going to have a little think about things, see what we can come up with. Then, broke lots of traffic laws in finding where Emily's staying for DPS, grabbed Nico's stuff from the college, dropped him back at the station and headed for home. A hell of a weekend, totally shattered, but frankly, one of the best weekends I could possibly have imagined! Pics ( Nico has embarrasing pictures of me, being eaten by an OHP machine, meeting Steve ), a better write up, and then the MP3 of the Q'n'A....lots of cool stuff this week And THEN - I've got to review Visions of Mars, and Bill Hartmann's book....busy busy busy Doug |

It was as great as Doug's splendid summary I tell ya!
Doug is as good as it gets IMO as a PR-guy for the Mer-mission, given the talks he's given, is about to do, and in daily socializing, we guys in Belgium need one just like it, and I might just give it a try And of course Steve, I can only confirm what Doug just said, he's one hell of a guy! He's a 'rock-star' -very charismatic, yet very down to earth, err-Mars that is ..and a joy to meet! I have enjoyed meeting Emily too, very nice person-and I'm about to join the society-for those who haven't- do so, it'll be well invested.. Join' em! Talking about nice people, Doug and Helen are too in real life! phew... But I'm off to bed now..I'm tired (though somehow it feels unjustified saying that after realizing ever so good what Steve and his team are sacrificing!)

I imagine here you are talking about Google Earth, it would be really amazing to have the same great stuff for Mars! Anyway, I think we probably should make a petition to ESA authorities, in order to show how strong is UE citizens interest in Mars imagery release!
