So our atmosphere is harsher, therefore if it can survive a drop in our atmostphere, then it in theory should survive in mars then....

Only for the re-entry phase, which they have a lot of experience with.

The problem may be that the air is too thin for a parachute to sufficiently slow the package down. Although the Martian gravity is lower than ours the thin atmosphere may make a parachute landing un-feasible. Even on Earth parachute landings can be harsh, hence why they used to land the re-entry modules into the sea before they started using the shuttle.

I'm not sure how robust the rover is, but even if it could survive the shock of a parachute landing what happens if it gets blown over a ravine, or bounces and rolls? Parachutes can be hard to stear (another reason for landing re-entry modules in the sea - large target) so a precise landing on a smooth surface can be hard to guarantee.

I'm sure they have thought things through and the sky crane was invented for a reason. Although it does look like an overly complicated design they tend not to do things for the hell of it.

Sensationalist title though for definite. Pulls in the readers and conspiracy theorists which are in abundance lately.

AFAIK though, i thought Australia's terrain was better suited for such experiments? I guess the budget cuts meant they had to compromise and go for something more local.
