Space Mission Design

Space Mission Design is a complex process, filled with challenges and triumphs, and it all starts with a simple idea.

Step 1: Mission Conceptualization

Every great space mission begins with a purpose. This could range from the pursuit of scientific knowledge, such as studying the Martian atmosphere, to commercial ventures like launching a satellite for global internet coverage. During this crucial phase, we outline our objectives, identify key stakeholders, and assess the feasibility of our mission.

Step 2: Preliminary Design and Technological Assessment

Once our mission concept is solidified, we move on to the preliminary design stage. Here, we select the technologies that will enable us to achieve our objectives. We consider the maturity and availability of the needed technology, identifying any gaps that might pose challenges. This stage often includes conducting trade-off studies to weigh different design options and technologies against each other.

Step 3: Detailed Design and Testing

After we’ve completed our preliminary design and technology assessment, we progress to a more detailed design phase. This is where we outline the specifications of our spacecraft and its subsystems, including its structure, propulsion system, power system, communication system, and payload. Each component must be designed to withstand the rigors of space and meet our mission’s requirements. Once the design is finalized, we test it rigorously to ensure it will perform optimally in space.

Step 4: Mission Planning and Operations

With our spacecraft design ready, we embark on the meticulous process of mission planning. This includes determining the spacecraft’s launch window, plotting its trajectory, and planning its operations upon reaching the target destination. Contingency planning and software development also take place during this phase.

Step 5: Launch

The day we’ve been waiting for arrives: launch day. Selecting a suitable launch vehicle and executing the launch itself is an exhilarating and critical phase of any space mission.

Step 6: In-Space Operations

Once our spacecraft is successfully in orbit, the mission operations team takes the reins. They are in charge of controlling the spacecraft, ensuring its health, and executing the mission’s planned operations, which could range from maneuvering the spacecraft to operating its instruments and communicating with Earth.

Step 7: End of Life

Every mission must eventually come to an end, and we must plan for the safe and responsible decommissioning of our spacecraft. This could involve deorbiting it, moving it to a graveyard orbit, or for interplanetary missions, leaving it on a celestial body.

Throughout these stages, there are additional key considerations that must shape our decisions:
