Spacecraft are man-made machines that operate in space. An orbiting spacecraft is normally referred to as a satellite, although it is manmade as opposed to a natural satellite like our moon. A spacecraft is typically subdivided into two major parts, the payload and the bus.   Where the mission can …

The function of the propulsion system is to produce thrust, which is the force that moves a rocket through air and space. Different propulsion systems generate thrust in different ways, but always through some application of Newton’s third law of motion. In any propulsion system, a working fluid is accelerated …

Introduction: Diminishing Manufacturing Sources and Material Shortages (DMSMS) pose significant challenges for industries worldwide, and the Department of Defense (DoD) is no exception. As a major procurer and user of advanced technologies and equipment, the DoD faces the constant risk of obsolescence and material shortages. However, the DoD has implemented …
