FWIW - accounting for the dust cover - it looks pretty much how Mars has always felt in my head.

This - also - is exactly how it looks in my head. http://mars.jpl.nasa.gov/msl/multimedia/ra...E1_DXXX&s=0

It's a judgement call at the end of the day. Even dragging a single JPG between two monitors that are not calibrated can result in dramatic changes. Ditto printers etc etc.

We'll be going the other way, it was intentionally thrown away from the science. And we'll almost certainly have HiRISE before we have MastCam of it.

MastCam will reveal all these questions in time..


No - MastCam (and or HiRISE) will tell us if the descent stage is right behind the rover ( which it should be ) but it can't tell us if the feature in those two RHAZ 256x256 from Sunday night are actually the impact plume.

Was it ever decided what the "plume" was in the first image? If that was the decent stage, I think the wreckage would be pretty bad and not of much use.


Given the rover heading being approx ESE - the descent stage would have headed 'backwards' from the rover - into the rear-haz FOV.

Personally, I consider it a very likely candidate. What I've not been able to establish is if those pre-cover deploy images will ever be returned at higher res than 256x256

I'm waiting patiently for one or more UMSF members to distinguish themselves by accurately predicting the location where the descent stage will be spotted in future HiRiSE imagery.

Doug's guess. 400 meteres from the rover on a bearing of 292 degs.

Be that as it may - I can tell you they ARE turned in - toe in - 40ish degrees.

All the wheels are oriented the same way. The way it appears in the front hazcam is not realistic...?


The front wheels are turned in 40ish degrees - they have been since final ATLO.

ODY doesn't need to go 'back' to Opportunity - it's perfectly capable of doing daily relay for both Opportunity and Curiosity. The plan is to use both, regularly. Why turn down an opportunity for an extra 100Mbits or so per sol?

How much did it differ from the pre-landing estimate? I know it's a pretty minor matter in the big scale of things; hope I'm not being too much of an anorak!


Well - Eyes on the Solar System was off by half a dozen seconds we think - and it was running OD142, a several week old predict.

Currently running on about 3 hours of sleep. Back to the office for the 9am press conf smile.gif

Is this what we're seeing, do you think..?


Personally - I agree with you We must be facing east given the shadow, and Sharp should indeed be visible to our east. A nominal touchdown toward the center of the ellipse would put the dunes in view also.

I'm afraid you're getting ahead of the game, Craig.

There hasn't been another UHF pass with the vehicle since that second ODY pass - so expect nothing new from the surface. I think social media is fairly in-tune with the HiRISE team and that they do indeed have something special to show us.

It not even midnight of Sol 0 yet - no HGA deployment details. No MARDI yet (we will get a few thumbnails later today - it will take weeks to get the full image sequence)

There has certainly been some fascinating discussion about what we can see in those early Hazcam images - hopefully some analysis of that as well.

Dark gravel, no rocks, local rise close to the horizon.... Could it have landed on top of the dune-field?


No - firstly, the ground is clearly has pebbels on it. Secondly - the FHZ image, small though it is - shows the dune field a dark linear feature to our east.

For those who might have had Java issues, we've retained the classic Unity browser plugin version that we're calling 'Classic' Eyes...

I will be doing a little talking on NASA TV just before landing.


And so will I - but much earlier than Rob. I'll be on at about 8.50pm local time during the educational pre-show to talk about Eyes on the Solar System and the AR App. Infact, my colleague Jon and I will be sat about 6 feet behind Gay, the presenter of the EDL broadcast, on Sunday night. Rob - I promise not to heckle. :-)

And - tomorrow morning ( at 10am and 11am local ) there is a Science, and an Engineering pre-landing conference. Both should be worth watching.... usual links apply - www.nasa.gov/ntv or www.ustream.tv/nasajpl or /nasajpl2

my understanding is that the lander radar will also look for hazards and direct the thrusters to avoid them, hazards such as boulders, embankments, etc.


No - it doesn't do that. It will land where it lands - and it's simply a statistics game as to how likely it is that there will be a problem.

All the radar does is plot altitude, vertical and horizontal velocity

Our cunning Java guru developer had this to say....

"predictions - ddeerrff is behind a proxy and imipak is using a 64-bit version of IE {which does not load the java plugin}."

He's putting some more bug-reporting stuff in place tonight.

Those are called rover-traps and they were taken into account during the landing site selection process thru Paolo's amazing work smile.gif

There are some, but not many - they represent a tiny tiny fraction of the ellipse.

For me it works fine on Win7 with FF or Chrome, OSX 10.6 on Safari, FF and Chrome, and 10.8 took some tricking (you can only activate java by spotlighting for java preferences) - but then it worked great. Infact, my little 13" Macbook Air is getting 30fps+ smile.gif

This is quite neat. Shades of the Phoenix EDL sim, only interactive. I did apparently uncover a bug, though. The hi-res landing area overlay is unaffected by zoom and only looks correct at the default 60 deg FOV.


Yeah - that's a symptom of a double-precision world being rendered on top of the normal 'Eyes..' - it's a mega kludge to get this thing working. We're going to just disable the zoom for the time-being. This one was on our list but needed a reminder - thanks.

I'm sending one of the Dev's this way to look at the Java based issues.

It's normal terra-firma miles. Of course, you can switch to KM under visual controls smile.gif

But yes - I think spoots/second is probably the best tongue.gif
