Space physicist Dan Hampton, an associate professor at the University of Alaska Geophysics Institute in Fairbanks, explains that sometimes rockets need to be defueled.

“When they do it at higher altitudes, the fuel turns into ice,” he said. “And if it’s in sunlight, when you’re in the dark on the ground, you can see it as a big cloud, and sometimes it’s spinning.”
