That kinda looks like it could have been taken on Earth.

Yeah, I agree all those different stages and maneuvers are ripe for failure. But I think the weight and size of the rover and sensitivity of all the instruments made any of the simpler designs not feasible.
Yeah, I certainly have no superior proposal. The fundamental goal is to take it from 13,000 mph to zero before touching the surface, as they've said. Each step gradually reduces the speed and puts them closer to that zero mark. In that respect, it's a good design. Without combining different braking systems, it wouldn't be possible (without breaking out the bubble wrap again). The parachute isn't enough on its own, using thrust on its own would consume insane amounts of fuel, etc.
The only part for me is lowering it on the cables from a hovering craft and then boosting away so it doesn't land on top of the rover. It obviously works, but that doesn't seem optimal.

A planet is a planet. And as far as types go, Mars is basically a stepbrother to Earth.

'Bout 1 cm of lead reduces gamma ray intensity by half, with multiplicative properties. Shielding can be done, it can just be expensive as hell to launch into space.
yea a cm of lead surrounding a spaceship big enough for a half dozen astronauts is gonna require way more fuel than we use now, unless of course we cut weight somewhere else.
whats the danger in space, gamma rays right? alpha and beta would easily be deflected by basically tinfoil but you need some thick concrete or lead or water to block dem gammas, wonder how theyll avoid that in manned missions.
Whats wrong with gamma rays? A couple of gamma rays never hurt anyone, just ask Bruce Banner. It seemed to work out pretty well for him...

Shield it in space

Not to mention, cutting the intensity in half won't do much with a high intensity to start with. You'll need several centimeters to be safe, I'd wager.

Preferably with lead from a mined asteroid.

I just read this article...I got a chuckle out of it:

NASA Calls It A Mission As Curiosity Rover Fills Up Whole 2-Gigabyte Memory Card
PASADENA, CA—Barely 72 hours after the landing of its Mars rover, NASA officials announced Thursday that their mission had ended, as Curiosity's two-gigabyte memory card was now filled to capacity. "Well, that's that, folks," said chief scientist John Grotzinger, explaining that after Curiosity's Mars Descent Imager took an especially high-resolution JPEG of the Aeolis Mons mountain, the $2.5-billion rover’s SanDisk card only had 0.03 GB of space remaining. "Honestly, we thought two gigs would be more than enough. That's like a 1,000 pictures, right? I guess we probably should have deleted those old Hubble photos off there before the mission." Grotzinger confirmed that even if the rover had been equipped with a larger memory card, it likely would have had only enough power for a few more hours of exploration before it had to return to Earth to have its battery recharged.
I think outer space would be awesome. I have been thinking about saving up for a Zero-G airplane ride. Thats probably the closest I'll get to outer space.
I still can't believe that crane shit actually worked
Same here. I'm glad it worked for them; I hope they figure something else out before the next round.
