Several techniques have been developed to assess the size of these structures. However, when used independently they fail to provide a full picture of the asteroid surface texture. We are proposing to use several techniques ranging from polarimetry, spectroscopy, radar delay-doppler, and photometry to obtain a full characterization of a sample of selected Near-Earth objects and derive the grain size or surface structure using independent techniques. During the 2023A semester we are proposing to observe the asteroid 1994 XD and 2002 KL6 with MIRSI using 3 different filters. We are estimating their thermal flux to range from 0.35 to 1 Jy.
