I think Viking and Voyager are almost Eagle-like in size - so I dont think that's them to be honest. There are a number of smaller craters en-route in the Argo scale

The moon on the left moved a lot during the three images this was done with - so it was a big of a botch-job to create that, but I really like it smile.gif

That is really great. Doug, are the .rad's for sols that recent publicly available somewhere?

Ermm. no

Oh - look - an interesting page of images form Sol 180

Evil demonstration of the auto-stretch differences between an image with sky in it, and images without rolleyes.gif

I have all but the 3 most interesting octants sort out calibrated - but I'm waiting for the tenesse section before picking which part of it I want to do properly.

I realize that the Airbag system has reached its limit for mass, but it is hard to argue with success: 3 for 3 attempts with very different landing condiitons.

I dont think anyone is saying "airbags are crap" - I think people are saying that it's simply impossible to scale it up to the capacity needed for more able missions. Not only that, but the Airbag system is highly limited as to the terrain it can visit. Skycrane or similar isnt going to be as limited.

I wonder where the name "Albert" came from? unsure.gif smile.gif

Queen Victoria's husband. I also came up with loads of other names ( the flat area next to Albert with little etched terrain I called 'Albert Dock' which is in liverpool, and lots of smaller craters after Albert and Victorias children. There's one quite large bit of etched terrain that I called 'The V&A' after the Victoria and Albert museum tongue.gif

But what difference is images of the sun going to make? If you trust the camera w.r.t. colours when it looks at the sun - then surely it is to be trusted w.r.t. colours of the ground smile.gif

It doesnt really achieve/alter/establish anything

the images taken away from the sun are more interesting - blank parts of sky - they produce some nice colours - they're taken quite regularly

You cant make any calculations of the colour of the sky based on the stuff from the exploratorium or the JPL raw image pages. You dont know how much one image has been stretched compared to any other image.

The killer with the Airbag system is the 300+ Kg of lander structure that serves no purpose after deployment I guess.

Put it this way - the roer was around 185kg. the entry-vehicle (minus cruise stage) was around 800kg

Not ideal really

Anyone got figures for Viking?

Hell yeah - Sepang GP, and the Sebring 12hrs (as a Brit - I'm beside myself over the DBR9 ). Not so happy with the new F1 regs - make a farce of things really.


Dragging things back on topic... smile.gif

This

http://207.7.139.5/mars/opportunity/forwar...T7P1215L0M1.JPG

Is at Site 50

THIS...

http://207.7.139.5/mars/opportunity/forwar...00P1214L0M1.JPG

Is site 51

If they were going to manouver to that rock in the first shot, they'd have simply kept the Site 50 reference. It's a different piece of rock I think

Turn in place at the end of a long drive is common - it lines up the UHF antenna ready for the Odyssey pass to reduce any obstructions by HGA/PMA/LGA for a UHF-Odyssey line of sight to get the max uplink with minimum drop outs. Infact, they have turned in place DURING a UHF pass in the past. And best of all, they've turned in place, taken photographs and done a UHF pass all at the same time on one occasion tongue.gif

Usually - they'll face the rover E-ish or W-ish so that nothing obstructs the UHF antenna. If they face north - then at the beginning of the pass, the PMA can get in the way for the first half of a pass. If they face south - then typically the PMA will obstruct the end of the pass. I dont know this for SURE - I'm just guessing that's why they turn 90 degrees at the end of the day. I do know htey turn specifically for the UHF pass though

Looks like they skipped straight past that little bit of rock and carried on driving. I wonder if they'll do much weekend driving - it'll be one HELL of a week for the odometer if they do. A 500m week anyone? Could be at Albert for April smile.gif

When I more formerly 'publish' stuff - I put a credit on it thus...

FWIW - If someone thinks something is worth stealing, then obviously it has enough value to be valid for protection of some sort.

Seriously, though (and I'm delighted to be asking this seriously), anyone wanna wager on whether one or both rovers make it (in some kind of useful condition) to Sol 1000?


The next major milestone in terms of longevity is in my opinion surviving a full Mars year (about 669 sols). The rovers will soon be 2/3rds there.

I will really celebrate that sol!

I had a quiet "woo yay" when the two rovers added up to that date -a year of martian surface operations smile.gif

I've been wondering for some time now if any of the software they use would have a "Sol 1000" problem. For example, in the pathnames for the raw images, the sol number is padded to three digits. I hope we get to find out.


My consultancy rates for the S1K problem are very reasonable....

I was thinking the same back on sol 99 smile.gif

"Hmm - wonder if the rover can handle up to 9999 or not?"

I guess we have time between now and then ( a year+ ) in which newer flight software could be written to eleviate the problem

QUOTE (Of counsel @ Mar 17 2005, 04:26 PM)
The more complicated question is whether your "derivative works" from those rover images are entitled to protection.  I'm not going to try to define where one draws the line between a derivative work (which is entitled to no copyright protection) and a protectible work that includes enough "creative expression" to differentiate it from the orginal JPL images.

I think the difference between

http://anserver1.eprsl.wustl.edu/navigops/...ATA800P2267L2C1

and

http://mer.rlproject.com/s410_husband_t.jpg

is significant. It's the result of hours of work- and in the case of a full panorama, days of work.

Just because JPL have (or in the case of the Larry's Lookout pan, will) taken the same data to generate a different looking mosaic imho doesnt weaken the fact that when I generate something as a result of hard work from public data, that something is mine.

The same is true of the images within 'Full Moon' for instance. Yes - source imagery is freely available photographs - but the stitching work he did to generate the large panoramas render the results to be his own work. That they are published in a book doesnt render them any more or less his own work than a mosaic I publish online. You can bet your ass that if someone lifted imagery from Full Moon and passed it off without credit, Random House / Johnathan Cape would be after them, and rightly so.

If imagery I, or anyone else have made is worth 'lifting' without credit, then imho it infers that the creativity and effort involved in making it is of a scale that defines it as being eligable for copyright. If it wasnt, then the person 'lifting' it would simply make it themselves instead of grabbing it. This is where I wrongly assumed spacedaily had gone wrong, in actual fact, Stephen had generated the RGB imagery himself - and it was basically the same as what had appeared here - indistiguishable - so even if he HAD lifted it, it wouldnt really be an issue.

HOWEVER

A large, complex mosaic, panorama, animation etc - that is a different story. There is creativity, time, experience and in the case of some panorama software - money involved in making that picture - as a result it is someones property.

An even greater issue than this, however, the moral issue. You just dont steal someones hard work - it's as simple as that. Ask them, give them credit, but dont take without asking. That is something that has happened with an image of mine on a website I found whilst randonly googling. Not even downloaded and added to their own webspace - actually straight direct linked from my own webspace. I simply re-uploaded the image with the words "IMAGE THIEF" on top of it wink.gif
