        The moon has long day and night cycles of baking heat and freezing cold, all taking place in vacuum. All moisture would be completely driven out and life for the microbes usually responsible for decay would be intolerable. The end result is some sort of dessicated mummification with added crispy finish. I suspect that they would look after a while not dissimilar to embalmed Egyptian mummies - skeletal structure in tact but the remaining flesh shrivelled and caked to the bone.  
 
That's assuming that the lander actually breached upon impact. If it didn't then the expired bodies would have also had time to rot extensively in the pressurised atmosphere.

CarolOklaNola say: Do you  have  ANY  idea  how  many    things   are  in  gi  tracts  an  and lugs  of human  beings...   Yes,  The  bodies  would  have  decayed  if  they  died  by  asphyxiation,  BUT    it  the    the  crash  released  the  air    And  they   died  in  less  than  half hour   to  several hours  because  of oxygen  deprivation  to    the  brain  and  body,  They  would have  freeze  dried.  it  would NOT happen instantaneously.  I  can  personally  testify  that  slow  oxygen  deprivation  to  the  body  and  brain  because or viral pneumonia IS NOT  pleasant.

Andrew say: the apollo 11 might have shattered into pieces and then stayed on the moon. The astronauts would not decay due to the lack of oxygen.
-
Bill say: They would have Decayed.   Inside the sapce suites.
