Space/Science » in reply to Spirit has successfully gone down the ramp and is now on Mars.

look at the tyre!

Look carefully at the bottom right, at the rear wheel. See how this wierd surface dust is sticking to the tyre like nothing on Earth*, and rucking up against the suspension. I hope this does not prove an obstacle to manouvrability, but it's certainly unexpected. Nothing like this happened at Viking when they trenched, or to Pathfinder, so Gusev is proving a VERY interesting site indeed.

The closest analogue on Earth would be snow when it's just the right consistency to pack, and you can roll a snowball and it sticks together with that funy creaking sound, and gathers a giant spiral of snow, while plucking your lawn clean...

(And no, I don't seriously think it IS snow, but I'd love to know how it works!)
