Spacecraft Propulsion System Sizing Tool image

Historically, the propulsion system of a spacecraft can be 25-50% of the spacecraft wet mass (the spacecraft's mass before liftoff). Understanding the mass of the propulsion system early in the design process gives spacecraft mission planners a better understanding of the amount of mass that can...

MSFC Engineering process diagram

The project has four main tasks:

(1) Understand how modeling and simulation is used in systems engineering in general, and in particular, at MSFC. We are interviewing key systems engineering practitioners and managers at MSFC, examining NASA systems engineering standards, and reviewing...
