If they want a really robust test location to simulate unknown Martian landing conditions they should go to the desert areas in and around Joshua Tree National Park.

Good call, ElkGroveDan. After Rogers, we continued helicopter radar testing over Amboy Crater and Cadiz Sand Dunes about 50 miles north of Joshua Tree. Amboy has morphology (terrain shapes) similar to Eberswalde Crater and Mawrth. Cadiz Sand Dunes allowed us to test the radar over more "fluffy" terrain to make sure it doesn't absorb or otherwise dillute the radar beams (we found it doesn't). We also flew over Death Valley which has terrain similar to what we see from MRO images of Holden Crater and Eberswalde Crater. It also contains "Mars Hill" which has rock distributions strikingly like some sites on Mars (it looks a lot like the the Viking 2 site at Utopia Planitia).

Great to have you aboard Steven. I tried to stop by Amboy with Doug Ellison last year but in the two decades since I went there on a geology field course the Park Service has closed off the road to the crater leaving only a foot trail and the sun was going down. But we did make it to Mars Hill the next day. Funny you would mention Cadiz. When Spirit first began looking back from Larry's Lookout it reminded me of the view from the hills above Cadiz. I would imagine that a jaunt up the Western side of the Owens Valley with all that fractured basalt and the number of cinder cones would provide for some challenging terrain for the radar too.

Please drop back in every now and then when you can and let us know how it's all going.

The high-speed photography of chute deployment is a beautiful organic flowing rippling sea-creature like event that is worth watching on its own. Stunning.

"Weighing almost a ton, the nuclear-isotope-powered is set for launch in the fall of next year, with landing on Mars almost a year after that."

They missed a word out in that scentence, and aren't they supposed to be using tonnes ?............. rolleyes.gif

Let's just hope it can negotiate sand traps. I wonder if they tested it in soft ground.

The wheels were installed onto Curiosity on June 28 and 29. Unless problems crop up during testing that would cause them to be removed again, the wheels are now permanently attached to the rover.

Good point. Of coarse they wouldn't test the flight model, but I hope they have tested it with an engineering model to see how it does in soft soil. The wider wheels on MSL should help quite abit.

Doug commented on this some time ago - MSL should be better able to deal with soft terrain than the MER's. It may be bigger but its weight is distributed over a proportionally larger contact area.

I doubt there can ever be a wheeled vehicle that cannot be trapped in some hellish sand trap. No doubt the drivers though will be very carefull.

That's very true but MSL has the benefit of the incredible expertise that has been acquired through the MER's - being careful goes without saying but that expertise is also invaluable. I'm not worried about sand or any other obstacles on the ground - EDL is what I'm saving all my worries for.
