Definition
The term, in context
AI-assisted draft · approved dataset
NASA's DAPHNE, short for Dynamic Atmosphere-Ionosphere Explorer, is a two-satellite mission carrying matched instrument suites that measure neutral winds, temperature, and gas composition in Earth's upper atmosphere. By flying identical spacecraft together, DAPHNE studies how variability in the lower atmosphere propagates upward to influence the ionosphere and space weather, phenomena that can disrupt GPS signals, radio communication, and satellite drag.
