A YouTuber built a 3D replica of NASA's cryogenic nano-actuators

Onboard the Webb space telescope, they are engineering marvels.

Just one glance at NASA's James Webb Space Telescope can convince you that you're gazing at a technological wonder of the world. From a reflector the size of a tennis court yet thinner than a human hair to a crypto cooler that keeps the instrumentation extremely cold, it's jam-packed with incredible technology that each require their own in-depth explanations.

In this video by the YouTube channel Breaking Taps, you can see an in-depth look into one of the most impressive pieces of technology on the entire telescope: the cryogenic mirror nano-actuators. To get to the bottom of these tiny mechanical motors, the YouTuber built a 3D replica to see how it worked himself. If you're interested in learning more, be sure to check out the video attached above, and as always, thanks for watching.
