And that seems to be the answer - the moon wobbles a little so at times you see more or less. According to earthsky.org http://earthsky.org/space/how-much-of-the-moon-can-we-see-from-earth-lunar-libration we usually see 50% of the moon's surface but at times we can see as much as 59%.

We then did a search using the terms We got many results and got these answers on the site Quora - https://www.quora.com/Which-side-of-the-Moon-did-the-Americans-land-on-the-dark-side-or-the-other-side. We didn't think this was definitive enough so we did an advanced search limiting our seach to .gov sites and got this result Operational Constraints on Landing Sites https://www.hq.nasa.gov/pao/History/SP-4214/ch6-2.html It gives a very detailed explanation of why the landings needed to be on the near side - radio communications was key as was having some knowledge of the topography and much more was known about the near side then the far side. This article also points out to how the site was selected - http://history.nasa.gov/SP-4029/Apollo_11a_Summary.htm<br />They definitely wanted to know as much about the site as possible and the near side was what they had information on.

Why were all of the landing sites on THIS side?<br />A: This side is better known and had maps. Plus is the one we always see due to Tidal lock. Plus in the other side communications were not possible <br /><br />2. Why would the Moon's face be slightly different during different times of the lunar month?<br />Due to its shape and also tidal lock. We see the same face but not same stage. And as we are close or far moon shape has variations and that is why the craters on the Moon's edge seemed to be in slightly different places.<br /><br />Will be back with more and also I'll re-confirm my findingsRamon Gonzalezhttps://www.blogger.com/profile/16129830563029534511noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-87720225713682563482017-01-04T08:47:55.713-08:002017-01-04T08:47:55.713-08:001) All the missions were to the near side due to t...1) All the missions were to the near side due to the lack of communications to the far side of the moon. Also, the near side was mapped in much better detail, making a landing easier to plan.<br /><br />The communication part I pretty well knew reading the question. I also did a quick search for "apollo mission near side" and one of the results mentioned the mapping issue, which also makes pretty good sense.<br /><br />2) The moon librates (wobbles) in its orbit, showing slightly more than 50% of its surface. Again, knew this off the top of my head. A quick search for "moon libration" returns a link to earthsky.com which puts the number at about 59%.Matthew Jhttps://www.blogger.com/profile/14173275744727165522noreply@blogger.com
