| Apr 8, 2018 at 13:01 | comment | added | Organic Marble | And here's a SPARTAN free-flying release and catch satellite from Shuttle - it's louver-tacular! airandspace.si.edu/webimages/collections/full/… | |
| Apr 8, 2018 at 12:52 | comment | added | Organic Marble | Here's a rather famous Shuttle payload with thermal louvers, between the arm attachment point and the white rectangular instrument. spaceflight.nasa.gov/gallery/images/shuttle/sts-109/hires/… | |
| Apr 8, 2018 at 12:22 | comment | added | Organic Marble | Lets see if we can get @prakhar to up their game with some better links etc. Their answer is right just not well supported. | |
| Apr 8, 2018 at 12:17 | comment | added | uhoh | @OrganicMarble So far the only thing I have to go on (re Mariner 4) is one hard-to-read bit of writing on the first image in the only answer (so far). I you would be interested in adding a supporting answer with a bit more about louvers (and a Shuttle-era example for comparison and/or that cool 10x10cm item in your new link) that would be great! | |
| Apr 8, 2018 at 12:08 | comment | added | Organic Marble | They are quite common. Used to see them on shuttle payloads all the time. And now cubesats nasa.gov/feature/goddard/2016/… | |
| Apr 8, 2018 at 12:03 | comment | added | uhoh | @OrganicMarble okay, indeed louvers are "a thing". | |
| Apr 8, 2018 at 11:54 | comment | added | Organic Marble | Look at the textbook linked in my answer to your old question, it describes "venetian blind" louvers on the same page as pinwheels. | |
| Apr 8, 2018 at 11:44 | comment | added | uhoh | @OrganicMarble r.e Mariner 4 I just don't know either way yet. The large and yet flat apertures shown in your link expose the surface to almost 2π of space, whereas louvers are restrictive and have a preferred, more narrow direction of exposure to space, so they would be less effective. I want to wait until I can read further. | |
| Apr 8, 2018 at 10:39 | comment | added | Organic Marble | Aren't they temperature control devices on both spacecraft? Just one spins and the other louvers open, to control the amount of heat rejected? | |
| Apr 8, 2018 at 10:36 | comment | added | uhoh | @OrganicMarble I'm not so sure that these structures on the side of Mariner-4's are actually louvers or vents. But thanks for the link, I remember that one now :-) | |
