One day after a Chinese rocket disintegrated brightly over the western USA, another set of strange lights appeared over the same region. This time it was NASA’s doing. Before sunrise on Feb. 25th, a Terrier-Black Brant research rocket lifted off from White Sands Missile Range in southern New Mexico, carrying an experiment to Earth’s ionosphere. Vapors released by the rocket created a luminous red blob in the dawn sky, shown here over Mesa, Arizona:
“I got up to put the garbage outside just before sunrise and swore I saw something glowing in the sky,” reports photographer Jasper Nance. “I thought I was crazy so I ran inside to grab my camera. Once my eyes were dark adjusted there was no missing the huge red splotch just above where the sun might rise. I watched it for about half an hour until the sunrise was too bright to see it any longer”
The ionosphere is a layer of Earth’s upper atmosphere where solar UV radiation knocks electrons off atoms and molecules. Plasma in the ionosphere is crucial to over-the-horizon radio communications, and also affects the quality of GPS navigation and other modern technologies. According to a White Sands press release, ground stations monitored the cloud to gather data on “natural wave-like structures referred to as traveling ionospheric disturbances.”
