Four NASA suborbital sounding rockets leapt into the night on January 26, from the University of Alaska’s Poker Flat Research Range. This time lapse composite image follows all four launches of the small, multi-stage rockets to explore winter’s mesmerizing, aurora-filled skies. During the exposures, stars trailed around the North Celestial Pole, high above the horizon at the site 30 miles north of Fairbanks, Alaska. Lidar, beams of pulsed green lasers, also left traces through the scene. Operating successfully, the payloads lofted were two Mesosphere-Lower Thermosphere Turbulence Experiments (M-TeX) and two Mesospheric Inversion-layer Stratified Turbulence (MIST) experiments, creating vapor trails at high altitudes to be tracked by ground-based observations.

四枚NASA亞軌道探空火箭於1月26日從阿拉斯加大學的Pokey Flat Research Range發射升空。這個時光延遲合成影像記錄了這四次小型多階段火箭的發射，旨在探索冬季令人著迷的極光天空。在曝光過程中，恆星圍繞北天極留下一道道光跡，高出阿拉斯加北極圈以北30英里的地平線之上。激光雷達（Lidar）以脈衝綠色激光束劃過場景。這四個實驗成功運行，載荷包括兩項中層-下熱層湍流實驗（M-TeX）和兩項中層逆溫層分層湍流實驗（MIST），在高空造成了可被地面觀測所追蹤的水汽尾跡。
