rockets going through the aurora borealis
NASA has its own earthly mysteries to study. This year, the administration is focusing its magnifying glass on the Aurora Borealis, the Arctic's family friendly, all-natural light show. The goal of the "Auroral Arcs" mission is to understand what factors influence the formation of the physical phenomenon. To do so, they sent four rockets straight through it, and now plan to analyze the flight patterns. The idea is that the rocket's landing is influenced by the same electric fields and physical forces that cause the Northern Lights' movements. NASA/Terry Zaperach
