Yep, space is evil, mean, and nasty to things we put there.
And getting there is NOT "half the fun".
And yet people stepped up and did very hard, painstaking work to "get it
And they all did it for free, out of love of the "hobby".
The truest meaning of the word "Amateur".
I applaud them all, and thank them for being the trailblazers.
