Then why are they sterilizing landers?


Because they don't want cross contamination on their instruments.


Do they also sterilize satellites?

Actually, yes. And build them in 'clean rooms'.


For what reason? Sensitive instruments?

As for the moon, did they sterilize the suits used for moon walks?

Yes.


Why?

Did the moon lander or the moon walkers expell any air while on the
moon?


What for? Certainly not to avoid cross
contamination on their instruments.

The lander probably did, since you had to evacuate the lander to get
out. The moon walkers, no. And the air would have been fairly
sterile.
