       On this day, forty years ago: 28 January 1986.I was working on my astronomy PhD in the terminal room at the Royal Observatory Edinburgh.Someone came in & told us the awful news. After so many launches & astronauts, we’d grown blasé & didn’t pay much attention anymore.That changed in 73 seconds on that cold day & we learned again that space is hard. I still remember their names:Onizuka, Smith, McAuliffe, Scobee, Jarvis, Resnick, & McNair. Ad astra, STS-51L Challenger crew ✨#space
