In any case, I too thought with the scopes they have today they would be able to take a much clearer photo than that.
If it was a terrestrial telescope used to take the photo (Im sure it was), there might not have been time to utilize adaptive optics capability (to erase the effects of atmospheric turbulence). Also, the existing photo is probably pretty dang good in terms of resolution.
Oh but, we can send a man to the moon?
