Tune in tomorrow from 11 - 3 PST. Live from the clean room, should be worth watching!

They will have used the calibrated process imagery that will eventually make it into the PDS>

As with MER, the JPG's are rough, ready, unprocessed and stretched.

I can't wait for Dan Maas animation.


Dan's not doing this one - but an updated version of the MSL animation that already exists is in production.

I don't know is super-res techniques can be applied to bushbroom cameras at all. Framing cameras, sure, but pushbroom - I don't know. You'd have to map-project before you stacked, so at that point I think you're already working with 'pixels' that never existed anyway.

I've never found one. Alice has delivered very up to date data - as has MIRO and IES

I heard from the ESA Ops guys on Monday that the OSIRIS team isn't planning on releasing any more images.


Entirely unsurprising, but still disappointing.

Given that they've not dumped any of the data taken since launch to the PSA, those holding their breath for more imagery will probably have to do so for quite a few years.

The comparison to a "100 watt light bulb" is rather misleading though, isn't it?


It tells people what the number actually means. It's the opposite of misleading.

And what that amount can let the rover do is self evidence by reading what the rover has actually done.... specifically
"With the extra energy from the Sol 2298 cleaning event, Opportunity was able to perform back-to-back drives on Sols 2299 and 2300 (July 12 and 14, 2010), each over 70 meters (230 feet)."

Furthermore - there are many issues besides Whrs that dictate what the rover can and can't do on a given sol. To state Xhrs of driving would be very misleading- because other factors means they can't necessarily do that every day.

Dust is being put into and dropping out of the atmosphere all the time basically. DD's are especially good at picking it up. Major dust storms kick up more dust and then, as they clear, dump that dust back down again.

That's quite a giggle for those that remember the wheels on the MSL Scarecrow mobility model - check the tread on that

it looks like they stop and dig in on a regular basis -- what causes this?


It's a cleat on each wheel - used to bolt the thing down to the lander. Each time the wheel turns, it just leaves that inprint behind.

Isn't it just. It's like that James Caird, Naturaliste etc area, just going backwards. It'll be like Anatolia and Fram before too long.

Two points.

Firstly, after six and a half years, surely you've learnt that the Xm/sol divided by Ym to go = arrival date is utterly utterly useless. It's never worked, it's never going to work.

Secondly - this is NOT the place for that discussion. I'm not sure how many times we have to say it - this is a thread for route maps and route maps ONLY.

Dilo, Floyd, H4I - you should ALL know better, in both instances.

Worth noting in the case of spirit - Scientists have explicitly said that they didn't see Spirit's current sand trap coming.

I've not found a single animation package to be intuitive. A few colleagues are using Blender - and getting great results. It's free...as in beer. Worth a look perhaps.

I'm wondering if you could take word-pedantry to another website. Please, just don't have that discussion here, yet again.

You're not being quietly told to do anything. I've never experienced any such problem in any browser. Google for problems with invasion board and firefox if it'll be of any use.

Like it or not - they're doing this. And 'I told you so' if it fails is really rather bad taste, because none of us is equipped with enough information about how well this mission has actually come together and how realistic and ambitious it actually is.

As discussions go, it's fairly rich in futility.

Love it (reminds me of the crystal markers up Husband Hill story)

BUT....

I don't think the rovers will get buried. There are lots of rover-sized-and-smaller things around not buried, and we've seen the rovers themselves get dirtier and cleaner over time. I think they'll get some dust around the wheels for sure - but they'll be stood there looking pretty much as Spirit does right now in many many hundreds of years.

The RAC has LED's to illuminate the contents of the scoop remember. But I think it was just dusk-like, not actual pitch black.
