One more good news: They still has one target marker left, they've led Hayabusa to land at the same place of the previous attempt.

Maybe not,

Very, very nice panoramas - and such wide angle views too. 


Thanks.

QUOTE (Airbag @ Nov 26 2005, 03:17 AM)
I assume they are based on pancam images, and then (by the looks of it) color adjusted for consistency?


Yes and kind of. I have a program that adjusts the brightness of individual pancam frames where they overlap, then when the individual frames are combined they produce images with matching colour.

QUOTE (Airbag @ Nov 26 2005, 03:17 AM)
Some of the skies looks perhaps a little too yellow for my liking, but what do I know, I have never been to Mars.  smile.gif


Maybe, the way I am combining the images to make the colour is for the ground, the sky comes out as it comes out. I then extend the sky with a simple bucket fill of the same colour which may look a little strange (all one colour) but I like having a bit more sky in the image and I'm not at the stage of being able to add more realistic looking skys yet.

On a similar topic, you'll notice that the overall colour is quite different between each pan, at the moment I have very little control over this. I'm guessing it must depend on the relative brightnesses of the raw images in each filter, I've just started writing an extention to my program to be able to adjust this. I assume people like the more 'reddy' colour of the Sol 653 East Basin best, right?

QUOTE (Airbag @ Nov 26 2005, 03:17 AM)
My only minor gripe would be that the otherwise very cool semi-transparent regions on your website make it somewhat hard to read the text in them when scrolling, given the static textured background behind them.

Thanks, for the feedback, I only threw it together very quickly. I might darken the background inside the boxes a bit, that will help.

For following Spirit across the Inner Basin I've put the full resolution version of my Sol 594-597 pan online on my new site. It's also been redone using MichaelT's AV routine and brightness/contrast adjusted since I posted it way back when.

Hmm, not sure what to make of this but the offending images appear to be up for deletion from Spirits flash:

Table of data products up for deletion:
Products Products Products
Still on Pending Already
Sol Seq.Ver Rover Deletion Deleted Description
--- --------- -------- -------- -------- -----------
672 p2548.14 5 0 0 pancam_post_brush_Osceola_L27

Which would imply that the images are on the ground and fine - I'm starting to think that the problem is with the scripts on the ground, the ones that get the jpegs made etc.

Also if there was a problem I would expect to some test images being taken on Sol 673, but all seems normal on the PDT...

Don't worry folks. smile.gif

They don't appear to be calibration images

These images: Seq P2548

are listed on the PDT as:

672 p2548.14 2 2 0 0 1 5 pancam_post_brush_Osceola_L27

No need to panic yet though, there are a lot of things that can go wrong between the image being taken and it appearing on Exploritorium.

The Inner Basin looks fasinating to me, I hope we don't rush to Home Plate too quickly!

Remember the way the layers of Husband hill are angled means that on this side were much lower in the stratigraphy than we have been before, this is important site seeing!

Nice one dilo, nice to have a picture of Spirit on her birthsol.

Your "mission primary target" line on the graph confused me at first, I was thinking "surely there was no target of ~70m/day" that was just me being tired and stupid! But it made me think that another way of marking that graph would be a differently shaded box between 0-90 sols and 0 - 600m showing just how far outside the original mission requirment envelope we now are. It seems a shame on a graph with clumulate distance traveled not to show that we're not far off 10 times the mission requirement!

Nice work, cheers,

James

QUOTE (Richard Trigaux @ Nov 22 2005, 06:49 AM)
perhaps that if the people who do searches like "Mars alien civilization attacks by UFO's" find this forum, they will get instruction, and realise that those who spread false theories are kooks.

Each time I was speaking of kooks on this site, it was alway about the spreaders of false theories. That 20% of the population believe them is not because 20% of the population are mad, it is because they are not enough instructed, or they are not confident with a society wich deceived them in a way or another. In such a situation, kooks have an easy play. If, with this forum, we can contribute to revert this situation, it would be of some use, not just a pass time for us.

A wise caution would be to use a language more accessible to common people, avoid "scientific style" and obscure abbreviations, and when we use an uncommon word, give the explanation. I began to do so recently , realizing that more and more people are reading us, not just specialist or enlightened amateurs.
Thas does not forbid to expell real kooks when there are some. Or to answer briefly but accurately to suspicious questions, as Doug used to do in many occasions. He did in this way, I think, to avoid to straightforwardly rebuff people who are just mislead by kooks, but who are not kooks themselves.
*


Well said Richard.

The kooks probably already have there sites and beliefs. It seems more likely to me that most people typing such terms into google are doing so to find out about the subject and are only potential kooks. If they head off to the kook site which tops the search then a new kook may be born; much better that they get directed here where we can persuade them otherwise. smile.gif

Well wadayaknow, turns out somebody has thought a bit more about this than us. wink.gif

Going back to the origonal question about what happens to a NS that goes below it's minimum mass. A quick astro-ph search gives a paper asking that very question in the title!

The fate of a neutron star just below the minimum mass: does it explode?

Very interesting, particualrly the introduction which give a whole load of references to other papers relevent to this disscussion (stripping matter off a NS)
