This tripped me up:<p><pre><code> &quot;I was not a big fan of designing a mechanical clock unless there was another option.&quot; </code></pre> So either this should be <i>&quot;... unless there was no other option&quot;,</i> or I&#x27;m completely misunderstanding.

Looking at the way the system is rigged to the wall of the station is quite humorous to me in how it is taking full advantage of being weightless. From the arm the camera is attached to the tracker, and then the tracker being mounted to the one arm just seems like it would collapse on itself if it were on terra firma.<p>I&#x27;ve seen some crazy&#x2F;shitty rigging done, but this one gets a pass because it&#x27;s in spaaaaaaaace

So the real magic is the clock mechanism, these guys bolted a 60:90 gear pair and called it a day. How about some kudos to the engineers that made the clock and the company that made them. They can then say to their friends &#x2F; family, hey one of my clocks is in space. Lots of glory to go around.

People are often quick to dismiss the impact of Starlink satellites on space photography, but here the impact is clear. Starlink ruins the photo.

&gt; Don is a bit of a machinist himself, so we decided to have some fun with the device name.<p>I don’t get it, anyone able to explain?

Neat.<p>Debbie Downer: Looks like it fairly easily could have been made with like 50% less mass.<p>Perhaps that wouldn&#x27;t have mattered though.
