I just posted a link to one of my favorite sites, space.com. I was born in '62 and was space-obsessed from a ridiculously early age. I knew the order of planets in our solar system before I started school and my family watched every step of the Apollo program with rapt attention. Apollo 10 is a touchstone for me, the dress rehearsal flight that anticipated what would come two months later.
If I could do math, I would have been an astronomer.
Excluding social media sites...a mix of current events stuff.
