Interplay of Rocket Exhaust and its Reflection on Water

June 02, 2021


Photographer: Michael Seeley

Summary Authors: Michael Seeley; Jim Foster

Shown above is a 195-second exposure of the launch of a SpaceX
Falcon9 rocket from Cape Canaveral, Florida. It was taken at
4:28 a.m. (local time) on March 24, 2021. I chose my viewing position
specifically to have water in view of the camera since I thought it
would be glassy enough to mirror the launch and the rocket’s
exhaust. As it turned out, the water, though not rough, was gently
rolling, creating the curious squiggles in the foreground that caught
my attention. This is something I hadn’t previously observed. The
exhaust's reflection on the water is known as a glitter path. Like
all such paths, it's composed of quickly moving points of light darting
over the water's surface. However, the "squiggles" are akin to moon
circles that can only be seen when the water surface is rippled. I find
the interplay between the water and the rocket exhaust to be quiet
