Rocket Launches Can Create Night-Shining Clouds Away from the Poles, NASA’s AIM Mission Reveals

07.21.2022
Near Earth’s poles, wispy, iridescent clouds often shimmer high in the summertime sky around dusk and dawn. These night-shining clouds are sometimes spotted farther from the poles as well, at a rate that varies dramatically from year to year. According to a new study using NASA’s AIM satellite, morning rocket launches are partly responsible.
