        "Description": "The DYNAMO-2 Dual Electrostatic Analyzer (DESA) instrument consisted of a single boom-mounted prototype sensor (DESA-NX-02A), and a main electronics box (MEB). The instrument was flown primarily as an engineering test flight of the DESA sensor and was only flown aboard the second of the two DYNAMO-2 rockets (35.357). The instrument had a single fixed field-of-view looking up towards space along the spin-axis of the rocket. For full details of the instrument, see Collinson et al., (2022). The instrument was configured as a low-energy photoelectron spectrometer.",
