This challenge was pretty unfair when I first posted it. It was much longer than the usual for these challenges, which has made it particularly hard to finish. Even after spinning out 20 cosmonauts into a separate challenge, there were still 35 people left to connect, which is two-and-a-half times as many as my standard challenge, which is 14.

At the same time, I have been reminded of a bunch of people whom I missed when I first posted this challenge, but adding them into an already oversized challenge would have been way too silly, even for me.

Therefore, I have taken the remaining unconnected people out of this challenge, added them to the "new" astronauts, and ended up with a list of exactly 14 people. (And isn't that handy?) So, that leases 27 space travellers whose profiles you have already connected to the main tree, or very nearly twice as many as the usual challenge. So I think it's entirely fair to regard this challenge as completed, and more than completed, and launch a new challenge.

My thanks and congratulations to all of you who have helped to connect these people. You are awesome.
