Let's deal with this picture. Can any rational person see anything wrong with this picture? I have a strange feeling that the round earth crew will see nothing wrong at all and it's all to be expected, as per usual. 

Are you referring to the buggy's rear left hand wheel being perched up?
Yeah! I know what you're going to say. You're going to say that N.A.S.A organised a strongman contest aren't you, or are you going to say that he jacked the buggy up to change a flat mesh tyre? 
Nope..
As with any car with a stiff body (if you're American you'd not understand that concept), when the car is on uneven ground, often a rear wheel will 'cock' because it's run out of suspension travel and the body won't flex enough for the wheel to rest...
he's clearly stopped the buggy on uneven ground.. this is, yet again.. a trivial and pointless observation..
I may as well say - ooh! his suit is white therefor he's a pumpkin.
Nice try, Spanky but no cigar. You see, if that was the case, then the opposite mud, I mean, fine moon dust guard on the other rear wheel, would not be seen, because it would be obscured by the raised wheel.
Plus I'm sure N.A.S.A would have been over the moon (get it?) to allow their astronaut to park like that and twist the frame on a 30 million dollar buggy. Sometimes I wonder why I even type this, it's so ludicrous to even think that people actually believe this stuff to be real. Honestly, I sit open mouthed, then I smirk.
