Yeah - just be carefull if you hear Scott making jet-engine noises within 20 feet of a workstation.

Got to be - it's not 'real' or it'd be in L & R.

Currently we, along with many other Invision boards, are getting dozens and dozens of spam registrations per day.

To protect the server and the forum, registration now includes a custom field to filter out automated spammers, as a very simple question.

If you have registered in the past week, but are still waiting for an approval email - please re-register, as your details were almost certainly lost in clearing out the vast number of spam registrations.

Threads merged. Jumpjack - that last post didn't deserve a new thread.

"which enables the rover to plan optimal long-range drives around any obstacles in order to travel the most direct safe route to the drive's designated destination."

Paolo was being sarcastic

As I said - link to the post they're in.

I don't want attachments doubled up purely to be put into an animation thread. If they're already on the forum, link to the post they're in.

It'd be scientifically interesting. Sort of a VVVVVVVLDEF

And, it would be cool.

Clearly a donkey leaving a trebuchet.

No - those two images are one and the same - the M1 at the end is the first produced version of that image. If a piece of it doesn't come down, or comes down again, they make an M2 version or M3 etc etc.

Were taken at the same time - and the feature is only in one - so it is an imaging artifact, not a real object.

Uphill, or when either front wheel is locked

Yeah, you were not here for Purgatory ripple. The adventure is wonderfull. The journey great, but, some of the footsteps can be very very painfull indeed.

Show of hands for those who enjoyed the stop-over at Purgatory and Olympia......wow - no hands

I see what you're saying - but it's not going to be like a path of joy the entire way.

MRO isn't doing MER relay at the moment as I understand it.

Restricted sols are not a symptom of relay schedules however. Odyssey will usually get a good pass in most days at about 4pm, MRO would get one (if used ) at about 3pm local.

The restriction is a symptom of rover-night and pasadena-day being out of sync. i.e. you have to start planning for Sol N+1 before you have the data for Sol N. Sol N's data can only be used for planning Sol N+2

So - as a result, everything sort of takes twice as long as you might expect. Tie that in with the fact that they didn't get post-drive imagery down until the sol AFTER the first drive, then you can see how the days add up.

Medusa, whos head Persus gave to......ATHENA (our MER payload!)

AH - ok - that I did not know - thanks for pointing it out.

""Nothing like this view has ever been seen on Mars," said Jim Whiteway, of York University, Toronto, lead scientist for the Canadian-supplied Meteorological Station on Phoenix. "We'll be looking for signs that the snow may even reach the ground.""

The difference, I think, is that MOLA is saying they saw CO2 snow, PHX is saying H2O snow. But in many respects 'nothing like this view has ever been seen' is true only because we've not had a LIDAR on the surface of Mars before.

It took 5 sols to cover that distance. Not two. Two drives - but five sols.

And this is just about the best driving terrain we'll ever have, and we wont have it for long ( at this pace ).

A fast couple of months, then it's going to be painfull.

Because clouds on Mars were not a new discovery, not a unique new finding. Snow is.

I have sent you a private message.

They will be able to carry on taking it after arm-ops are over, so it's more important to do what is necessary in support of arm ops first.

Doug

We do. The big picture dictates the driving trend. There's no point having a 'two week' map only to find we're two weeks down a dead end into a dune field.

This

doesn't tell me how to get to London.


This, however, does

I would disagree. We need to see the big picture so that we can make choices on route, hop between good areas if necessary. Infact, Paolo has specifically state that he doesn't want a single route drawn out.

Why do you need to ask me if you can try? The data's all at the HRSCView website, including an IDL based routine to turn it into easily usable formats.

You could get a million different answers for that. You could say that the purgatory style dunes in HiRISE imagery would have scared them off heading south, so they would have gone in another direction completely. You could say anything really. It wouldn't be any less or more right than any other answer.

I've tried using that HRSC DEM for animation - and it's...how can I put this politely.

Not very good.

I'll leave it there.

Those are not especially accurate 3D models - and they're a million miles from being CAD files.
