...Yeah! blink.gif Great idea, Dan!

Why DON'T they make Mars chutes in contrasting colors? There's some opportunistic science to be had (like rate of dust deposition) aside from the coolness factor. It must have something to do with cost, performance or even mass considerations, I'd guess, though the only thing I can think of is added manufacturing expense.

I imagine that (besides tradition) the cost of qualifying a relatively untested neon-green fabric for the critical entry mission may also have something to do with it.

Not the fabric so much (it's just normal nylon and polyester AFAIK) but the dye process. Dyeing nylon requires heat, and I suspect qualifying the process without a critical engineering reason to do so wasn't high on anyone's priority list.

Inside the Rover Factory

Like everything on MSL, it's big!

Does anyone have any idea what that "tin can" with the brown and black spiral markings is atop the RTGs? I haven't seen it in previous images.

It's not ontop of the RTG - it's mounted on one of the trusses that stands up at the back of the rover deck. It's the UHF antenna for relay to MODY/MEX/MRO

Reminds me of the Mike Myers "All Things Scottish" shop skit from Saturday Night Live: "They come in three sizes: wee, not so wee, and friggin' HUGE!"

Will Curiosity carry batteries as well as the RTGs? I know that it will have a constant power supply, but will batteries be required to give it an extra boost of power for driving ops, etc?

Here's the miniscule, almost infinitesimal heat shield.

Actually, you might say that in future MRO pics if it doesn't discolor much during reentry & lands upside down.

(We already talked about parachute colors, so I'll let this one slide! rolleyes.gif )
