This paper introduces a multi-satellite approach to passive microwave interferometric radiometry applied to geostationary atmospheric sounding at 53 GHz. The concept applies satellite formation flight to the currently operational interferometric tech
The paper presents the design, manufacturing and postproduction analysis of a novel high-temperature spacecraft resistojet heat exchanger manufactured through selective laser melting to validate the manufacturing approach. The work includes the analy
