I don't even have kids yet and I already feel bad for them!

On a more serious note, what an incredible project. There's all the very obvious stuff -- the creativity, the learning experience, the sense of wonder and ways it can inspire both the adults and kids -- but above all what sticks out to me is the amount of time that it took to put this together could have so easily... gone to waste? Like, what a nice way to have a hobby, spend time with your kids, and have something to show for it at the end? I worry that with the increased ease with which you can just "doom scroll," things like this are tougher and tougher to achieve. I remember as a child I'd get bored so I'd be FORCED to get my toys out and make up stories. In a similar vein, as an adult, this is such a positive outlet for "free time," but I worry that the attention economy has made committing to projects like these even harder (at the margin).

I applaud the rocket scientist (and astronaut!). Truly inspiring stuff!

Thank you so much for these very kind words. One of my personal pet peeves is people who see a passion project that has no practical purpose and say "You obviously have way too much time on your hands." Your comment was the opposite so I particularly appreciate it!
