jsc2023e046372 (9/30/2022) --- The Multi-Needle Langmuir Probe (m-NLP) is shown from the ram facing side with booms in deployed position. The m-NLP measures plasma density in the ionosphere, where Earth's atmosphere meets the beginning of space. Researchers aim to study electrically charged particles and increase their understanding of how particle phenomena affect radio communications and global navigation satellite system (GNSS) signals.
