Honestly some people are so gullible I have to mention a bridge I have for sale. What an absurd statement. Simple maths explains why the Hubble telescope cannot see the moon lander.
The lander is 400,000,000 metres away from the telescope and is 4 metres across; this gives it an angular size of (4/40000000) * 206265 = 0.002 arcseconds.
The Hubble has an angular resolution of 0.1 arcseconds. Get it now?
The reason it can see things 24 million light years away is because they are bloody big.
If man didn't get to the moon how is it that any nation on the planet is able to bounce a laser off a reflector left by Apollo 11?
Now about this bridge I have for sale - here is a picture of this hardly used bridge that I am willing to sell you at a very reasonable price.
