we cant see the remains of the lunar missions with satellites because of the scale of the distances involved.
If we used the Hubble telescope to look at the moon it would be similar to reading a book with a pair of extremely power binoculars. Hubble is used to look at objects Billions of light years away. whereas the moon is only 238,700 miles away. The galaxies that hubble examines are at least 5,878,786,100,000,000,000 miles away!
If we use earth pointing (weather) satellites the problem is reversed - weather satellites operate at approx 20,000 miles and can only focus at that distance..
