OTDIH. Good thread 👇🏻on the 1st Minnesota Infintry, which was heroic at Gettysburg and suffered devastating casualties. (Just one reason that I am extremely triggered when I see someone displaying a Confederate flag )
It’s been a hard and yet triumphant year for Minnesota. Ordinary people have been targeted by their fellow countrymen, and made heroic sacrifices for their neighbors.
So, appropriate to remember that 163 years ago today, 262 average Minnesotans sacrificed themselves at the Battle of Gettysburg.

The first color image from the surface of Mars was released a day later, July 21, 1976.
It was *not* the one you see today! Viking scientists were so surprised by the orange skies that they initially shifted the color calibration to make Mars look more Earthlike. 🧪🔭
