As Glenn Reynolds of Instapundit said, “This is cool”. Yes, and otherwordly beautiful as well. “SpaceX Falcon 9 Creates a ‘twilight phenomenon. This is breathtaking.”

A twilight phenomenon is produced when exhaust particles from a missile or rocket propellant left in the vapor trail of a launch vehicle condense, freeze and then expand in the less dense upper atmosphere. The exhaust plume, which is suspended against a dark sky, is then illuminated by reflective high-altitude sunlight through dispersion, which produces a spectacular, colorful effect when seen at ground level.
The phenomenon typically occurs with launches that take place either 30 to 60 minutes before sunrise or after sunset when a booster rocket or missile rises out of the darkness and into a sunlit area, relative to an observer’s perspective on the ground. Because rocket trails extend high into the stratosphere and mesosphere, they catch high-altitude sunlight long after the sun has set on the ground. The small particles in the expanding exhaust plume or “cloud” diffract sunlight and produce the rose, blue, green and orange colors—much like a dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow) – thereby making the twilight phenomenon all the more spectacular.[1]
The only downer to this is that the Eco-Socialists truly believe this is air pollution on a grand scale. The really do believe that all that money being spent on space exploration (and soon, commerce) should be used for “their” other purposes – like the Green New Deal types of things….
Up Yours – this is gorgeous. And once again, the Socialists show that they are the No Fun And No Humor League.
