Spacecraft connections get Adam Savage's Smithsonian treatment

Apollo curator Dr. Teasel Muir-Harmony introduces the APAS-75 docking hardware from the Apollo-Soyuz Test Project.

A spacecraft connector proved the biggest draw among Adam Savage's Tested uploads, in a week that also found room for aircraft chairs, telescope mirrors and guitar wiring. Eight videos arrived, with "Meet an Androgynous Space Docking Module" reaching about 1.3 million views.

At the Smithsonian's National Air and Space Museum, Apollo curator Dr. Teasel Muir-Harmony introduces Savage to the APAS-75 from the 1975 Apollo-Soyuz Test Project and explains the "androgynous" in its name. Beneath the terminology is an appealing engineering idea: mating interfaces that do not require separate male and female designs. Viewers pick up on the practical advantages of compatible connections, with some discussing how the design's descendants continued in spaceflight.

The museum visit extends to "Humanity's Greatest Engineering Feat?", where curator Samantha Thompson walks Adam through the James Webb Space Telescope Pathfinder. This full-scale engineering model helped test the telescope before launch. Among its details are two beryllium mirrors, one bare and one carrying a microscopically thin gold coating.

Back in the workshop, the newest guitar project is the channel's busiest upload by daily views. Despite "Adam Savage Upgrades His Gibson Les Paul Guitar!" in the title, the description identifies the instrument as a Chinese-made Tokai variant of the Les Paul design. Adam replaces its electronics, then adds an engine-turned finish to two rear panels. The Formlabs printer review is another active draw, moving from miniature-print tests to the engineering inside the machine.

Subscribers held steady across the week, while total viewing reached roughly 5.8 million. Today's viewing is much slower than Tested's usual daily pace, though its weekly total sits behind only Wisdom Pouchannel and Architectural Digest among the nearby DIY channels. For Adam, the latest hands-on assignment is still wonderfully specific: making the back of a guitar worth a closer look.

What viewers say

  • It really makes the most sense though. Now there's only one design to build and any ship can dock with another with that part.

  • What's funny is that there are significant advantages of an androgynous docking standard. To the point that NASA is still using an evolution of APAS today.

  • Most electrical connectors are referred as male or female too. Sometimes there are connectors that fit either way with a single part (such as Anderson style battery connectors) that get referred to as Hermaphroditic instead.

  • This is also very smart because that way every craft can dock with another one on each port.
