Note sure this is a good justification, but it&#x27;s the only claimed advantage I could find in their main paper:<p>&gt; 2) Unlike space-based observations, the Moon provides a
large stable platform for maintaining astronomical instruments in permanently stable configurations. The rotation
angular velocity of the Moon is about 0.55″&#x2F;s, which is
about 27 times slower than the Earth. The slow rotation
allows long term monitoring without interruption for as long
as about 10 days.<p><a href="http:&#x2F;&#x2F;link.springer.com&#x2F;article&#x2F;10.1007&#x2F;s11433-011-4255-7" rel="nofollow">http:&#x2F;&#x2F;link.springer.com&#x2F;article&#x2F;10.1007&#x2F;s11433-011-4255-7</a>
