Photographer Christopher Jones notes this interesting sight is a view of the inside of the bottom cone of a rocket engine. It is the type used in the Titan II. Now that we know what it is, it is more understandable that it looks like something out-of-this-world. I see a mash-up of many things: copper molds, a metal colander, a washing machine agitator, and a shuttlecock name just a few.
The textures in this image are the main anchor to its beauty, the light reflecting off edges and between ridges. All of the little details put in place after extensive engineering and testing now look simply like advertent surface embellishments. Outward ridges shining like sun rays, this component has been among the stars, which is awesome in itself.
