I don&#x27;t agree that the SpaceX landing is better than Apollo 11.  I don&#x27;t measure something in &quot;How available is the technology to me?&quot;.  I measure in &quot;How hard is that?&quot;.  I&#x27;m not downplaying what SpaceX did to be controversial.<p>I&#x27;m just of the opinion that the challenges that NASA had to overcome 50 years ago to get to the moon involved alot more &quot;unknown&quot; information.<p>I think anyone who has wanted to do &quot;something that&#x27;s never been done before&quot; can appreciate the trailblazers that had no other option than to make an educated guess because algorithms, processing power, failure modes did not exist.
