Tracking the Albedo and Thermal Radiation with a Lunar Narrow Field of View Radiometer

A lunar narrow field of view radiometer (LNR) is designed to measure the short and long-wave radiation from a lunar orbiter as a part of the Lunar Research Program (AYAP-1) by the Turkish Space Agency. The flying model has been developed and constructed based on the heritage of previous space missions and the lunar short-and long-wave radiation values determined by the Diviner lunar radiometer. The LNR is targeting a high-resolution and accurate lunar albedo and surface radiation measurement with a lunar radiation flux measurement through optimized optical and thermal-mechanical design. The measurement of the single-pixel LNR will cover a broadband wavelength range from 0.2 to $\mathbf{50}.\mathbf{0}\ \boldsymbol{\mu} \mathbf{m}$ and a footprint of 3.45 km² at a 150 km altitude.
