1. Design a solid or hybrid upper stage Propulsion Module (PM) with the capability to boost a 181 kg payload from a 352 km circular orbit to a 704 km circular orbit. Of the 181 kg payload, 125 kg is allocated for the experimental satellite, leaving no more than 56 kg for the PM. This problem gives you a head start for the type of calculation and design effort needed for the missions course. Show your design's a) throat area b) exit area c) exhaust velocity d) mass flow rate State any assumptions that you make. Hint, it takes 0.52 m/s to raise the orbit 1 km at an altitude of 352 km.
