Space invasion. As Is
Abstract
Two cases of space invasions into the atmosphere of the Earth are considered. The first event demonstrates a compli-cated flight trajectory of the "corkscrew" type. The second event is short-lived one with a lifetime of about two seconds. Both events left inversion traces in the Earth's troposphere. The effect of the "wobbling" of traces of meteors is considered, which occurs when a gas flows around the rotating body (the Magnus effect). The movement of the meteor in the frame of the compressed gas dynamics is considered. It is shown that the gas motion in the meteor trace can cause an inversion trace. Depending on the speed of the invasion, of meteoroid mass and atmospheric conditions, inversion tracks can be seen from fractions of a second and up to two hours.
