requires several strict conditions to occur: the launch must take place either shortly before sunrise or within half an hour after sunset, when sunlight at high altitudes can still illuminate the water vapor and ice crystals in the vehicle’s exhaust plume. Chinese launch vehicles use liquid oxygen and kerosene engines, which produce carbon dioxide and water during combustion. At high altitudes, these quickly condense into water vapor and ice crystals, creating this spectacular visual effect. |
