Space Systems Engineering Fundamentals
Space systems engineering usually encompasses space systems engineers who are part of a spacecraft program lifecycle from start to finish, including designing, building, testing, and, sometimes, deploying the spacecraft.
Additionally, space systems engineers need to have a technical understanding of all of the subsystems involved in a spacecraft, including the structural and electrical systems, thermal control, power, and communication.
In reality, many separate elements go into making a space system, with individual subsystems developed by specialist teams. System engineers, however, focus on the space system as a whole. They translate the needs from the users, design its architecture, define its building strategy and oversee the integration of subsystems to form the final result.
Development of scientific instrumentation and space-based systems also often falls under space systems engineering. Measurements and observations from space are of fundamental importance for physical sciences such as geophysics and astrophysics.
Space systems engineers are often called upon to design, develop, and qualify scientific space instruments and satellite systems and how to use advanced analysis methods and physical and mathematical modelling to ensure that these complex systems are compliant with mission requirements.
These instruments and support systems (e.g., navigation, communication) need also to operate and perform efficiently in the harsh conditions of space for which verification techniques before launch into space are essential to be implemented.
At NASA, space systems engineers are involved with projects when they are at their earliest Technology Readiness Levels. They assist in making sure that the finished product will be a tool that will help to meet and fulfill SCaN’s (Space Communication and Navigation) goals and objectives. This technology can be adopted and/or used by NASA missions.
Some would argue that because there can be so many potential solutions to each question, space systems engineering is as much an art as a science. In reality there are always a multitude of decisions and trade-offs made between the different options in terms of performance, risk, cost, reliability and turnaround time, among other factors.
In space systems engineering, a systems engineer has to be able to work across multiple disciplines (computers & software, electronics, power, thermal, structural) to be able to design systems that perform the intended function reliably, for a reasonable cost.
Add “space” to the equation, and the general job description doesn’t change much, but the intended function (fly in space), and the reasonable cost (high) are significantly different from most terrestrial engineering jobs.
Regarding satellites, space systems engineering involves the entire subsystems of the satellite such as Propulsion, thermal, Onboard Data handling, Attitude Control Systems, power and structure.
