    They cant even put men on the moon lately. Theyve got no chance of getting the technology and infrastructure to go to Mars and have people actually live there.

    I stepped away for a few minutes to stop a computer in my workshop from exploding. When I got back to my own workbench all the guys in the NASA control room were screaming and hugging eachother.
    I couldn`t tell if the landing had been successful or if they`d discovered the world was about to end.

    Ok, maybe someone more sciency (in another field - mine is genetics!) can tell me why that appeared to be over-complicated!

    I get that mars has an atmosphere so you need a big sophisticated bit of poo to get through it... then a smaller bit of poo comes from that to `land` officially... fair enough...

    But seriously... big bit of boo breaks through the atmosphere, thunderbird 2 hovers above the surface and lowers thunderbird 4 onto the mars surface only to fly off and crash somewhere?! - If it`s advanced enough to hover, it`s advanced enough to LAND INTACT, and have thunderbird 4 drive out! - Surely two bits of tech on the surface is better than just one!

    Explain! :)

    ...and if some idiot says thunderbird 4 is aquatic, you`re a twat! - I got that, I was using an `analogy` :-p

    "If it`s advanced enough to hover, it`s advanced enough to LAND INTACT, and have thunderbird 4 drive out!"

    They wanted to disturb the surface as little as possible and not end up with the rover covered in dust which could take quite a while to settle. That`s why it hovered above. It was crashed a distance away because it served no purpose anymore.

    @beternal: As it said on the poster, Mars atmosphere is alot thinner than earths hence there is less drag caused by parachutes so they can`t slow it down enough to prevent damage to the rover on landing. The old method (used on the previous two rovers) of using large inflatable bags around it so it bounced along the ground until it stopped would not work with this one as it`s so large the force would burst the bags. Hence retro rockets.

    Cool, thanks for the answer... But I still don`t see why it wouldn`t have been easier to land it, disturb the ground a bit, and simply drive it to somewhere less disturbed... seems like a lot of fuss!

    @beternal The dust would coat the rover and could affect the scientific instruments. Unfortunately there is no way to wash these things so once they get dirty they stay dirty (barring a little wind which is not powerful enough due to the low density of the atmosphere to clean effectively).
