This is the insignia of the 254th Combat Communications Group, a unit that’s normally part of the Texas Air National Guard, but if federalized, becomes part of the Air Force Space Command. It’s been around since 1952 – that’s 10 years before the first Telstar communications satellite, and 8 years before Echo 1 bounced the first communication signals through space. Of course in 1952, this was called the 221st Radio Relay Squadron and operated out of Springfield, Ohio. It wasn’t until 1971 tha…
Yes, Virginia, there is such a thing as a snipe. Lots of kinds of snipe, in fact.
And snipe hunting was a real thing, too.
This illustration is of a Wilson’s snipe, and it comes from A history of the game birds, wild-fowl and shore birds of Massachusetts and adjacent states…. by Edward Howe Forbush.

This might be the greatest contribution gardening ever made to space travel.
In the middle of World War II, engineers were trying to figure out how to make pressurized suits for military pilots who were going into ever-thinner layers of the atmosphere. One problem was once you’re on the inside of an inflated balloon, even one with arms and legs, it gets really hard to move. If you bend, the pressure goes up even farther. You tend to just… outstretch.
Electrical history from PW Lanier and the Minneapolis Institute of Art:
This tabletop Tesla coil was likely made for science classes, producing long, impressive sparks in the air and lighting a fluorescent tube held at a distance. Since a Tesla coil is really a radio transmitter without an antenna, Tesla is credited with helping invent the radio—he filed the first radio patent. And his legacy continues today, with his namesake battery-powered automobile and Tesla coils…
Not just a kangaroo, and not just a nail-tailed kangaroo. A lunated nail-tailed kangaroo. And a cute one, too. From John Gould’s The Mammals of Australia, 1863. Nowadays, Onychogalea lunata is called the crescent nail-tailed wallaby. I like to think they’re still cute, though.

This is a view of one of the automatic music-making devices collected by the Centre International de la Mécanique d’Art (CIMA), a Swiss museum of music boxes and automata. So, robots and machines that make art. Something people were making way before the first digital audio workstations came around.
