...you'll realize that the moon has been "marred" by humans since the Soviets either left metal fragments, or recondensed metal globs on its surface in Sept/1959 from what was left of Luna 2.
Frankly, if the moon is marred EITHER by meteorites/asteroids or by spacecraft...
So what?...Either way its marred.

But asteroids leave a much more visible
destructive effect [let's call it that] on the lunar surface than any human activity
[or impact] on the lunar surface.

By the way, Raoul, your CD message on the HUYGENS Titan-lander would hardly
be considered a financial investment
in that spaceprobe. The European taxpayer is picking up the tab.

My CD message is a [partial] financial investment in the TRAILBLAZER lunar orbiter, since tax money isn't being used
for that mission.
cheers.
