We all know that Bruce is just someone who has to criticise. Nothing sneaks under the radar with him. Whatever is in the news, Bruce thinks it's wrong. If something goes wrong, Bruce knew it would and could have told you 5 year previous. If something totally and fundamentally unexpected happens that could never have been forseen, Bruce wants to know why they didnt know it was going to happen, and he knew it would happen all along.

I've said it before, and I'm NOT going to say it again Bruce - if you want to exercise your habbit for unjustified ranting, do it elsewhere. Alex, myself and others had to put up with it for too long elsewhere, and I wont let the same mistake happen here. I'm posting this publicly so everyone can be a witness to it.

So what you're saying is that NASA should be doing NOAA's job?

This is a polar projectiong


and after Phil's excellent guidence, I've figured out how to do those. They're great for a sense of 'place' and cross referencing horizon features with maps or orbital imagery.

However - if you want to generate your own map like material, you need more of a vertical projection thus...


Now - I have no idea how to do that smile.gif Part of me thinks it could be fuged by stretching away at a polar projection, but is there a more obvious way using the 'ordinary' tools?

Is there any planed imaging with HiRISE on approach to Mars?
If not, why not?
[/quote]

Not that I know of - because the optical navigation camera is not boresighted with HiRISE and needs to be aimed in that direction.

Rough, ready, badly aligned, but it shows the extent of the thing.

I'm still missing a frame though.

Scientists say what they want
Engineers say what is possible
Management say what is fundable smile.gif

More seriously -it's a case of the engineering team dictating what the scope for rover activities are, and the scientists choosing what to do within that scope.

It's a hard balance. But they've told us for months about the need to get to slopes. The option is to either sit here and try and do science while the rover dies...or...get something quick, get to the good slopes (with actually a quite reasonable chance of a healthy rover in 4 or 5 months ) and then revisit West Spur again.

It's not a choice they're really having to make - the calender and the dust are making it for them.

Ahh - nice machine - I tried one at the Apple store in London. My current laptop is only a few months old - and it's a beauty - but come a few years time, if Apple have sorted out their laptop range a little better - whatever the Mac Book Pro becomes by then, I'll be 'shifting camps' so to speak smile.gif

Needs shadows - but they're cool smile.gif

If you do a drop shadow in photoshop, then make a layer from it, you can then warp / perspective / distort to make the shadow appear to cast in the right direction as based on other shadows in the scene smile.gif

I see a pair of color closeups in the latest pointed to pancan directory.
Bands 2,5,7 for the left cam and bands 2,(2+1)/2,1 for the right cam.


I believe that is the 'James_Papa_Cool_Bell' observation. Jim's out the office for a week or two and that looks like his colleagues at Cornell are having a joke at his expense smile.gif

I would LOVE to do a mission in one of those. Emily did one a few years ago, and it sounded like a lot of fun.

The correct link is http://www.msss.com/moc_gallery/r16_r21/im...8/R1801150.html (perhaps you copied it from a different forum post? )

FWIW - i dont see plumes - I see topology on the surace, but it's a matter of interpretation.

My guess is..


My guess is that they'll still trying to understand the MI images, the PC images, the TES data and the MB and APXS spectra to make the best interpretation of what they'll looking at. Things gont get answered by a single spectrum - they take context, understanding and interpretation.

Just want to repeat that the arm was safely stowed during launch and EDL, so that won't say much about whether it can take these bumps in an unstowed position.


Indeed - physically bolted to the WEB as well.

Sojourner was on 459.7 MHz, and MGS Relay is on 401.5275 MHz and 405.6250 MHz.

Soj-MPF was 9600 bps I think, where as MGS relay is 8 or 128.

I'm not sure if any other assets might have been able to listen in on Sojourner directly, but I dont think MGS could
