Vertically Aligned Carbon Nanotubes (VACNTs) possess numerous remarkable electrical, thermal and optical properties, including that they are the blackest known substance to humankind. This property, as well as their very light thermal mass, makes them ideal absorbers for radiation measurement instruments. Herein we describe a demonstration of VACNT-based radiometer technology to be carried on a commercial suborbital reusable launch vehicle (sRLV). The results of this proposed work and demonstration would raise the technology readiness level (TRL) of this technology from 3 to 7 enabling their proposed use in future NASA and operational Earth science missions.
