Spacecraft Systems & Mission Design — Prerequisites
What to Know Before Starting This Guide
This guide turns Orbital Mechanics' physics into an engineering input — the prerequisites are that technology's results plus Propulsion's Δv/rocket-equation framing, not new physics.
Required (Must Have)
1. Orbital Mechanics & Astrodynamics, Completed
•The LEO-to-GEO Hohmann transfer Δv figure (3,854 m/s) — Overview's mission Δv budget example reuses this exact number directly rather than recalculating it, so it needs to already be understood, not just recalled
•Comfort with Δv as "a cost, measured in velocity units, that propellant has to pay for" — this guide's entire mission-budget framework builds on that idea
2. Propulsion Systems, Completed
•Staging — Overview's explanation of why the spacecraft itself only carries propellant for orbital transfer and station-keeping (not the ~9.4 km/s launch-to-LEO cost) depends on understanding why staging exists
•The general relationship between Δv, propellant mass, and the rocket equation — Fundamentals in this guide uses that relationship directly to size propellant mass from the Δv budget Overview establishes
3. Flight Mechanics & Aircraft Structures, Completed (or at least Overview)
•Basic structural-loads framing — Overview references that the spacecraft structure subsystem has to survive "the specific launch loads covered in Flight Mechanics & Structures' load-factor content," assuming that connection is already meaningful to you
Nice to Have (Speeds Up Learning)
Basic Electrical/Power Concepts
The power subsystem material (solar panels, batteries, eclipse power budgeting) is easier with prior exposure to basic power/energy concepts (watts, watt-hours) — not required, since the guide introduces what's needed.
Any Programming/Scripting Experience
Installation sets up a Python-based workflow for Δv-budget and subsystem-sizing calculations — prior scripting experience in any language speeds this up.
What You Do NOT Need
•Prior exposure to actual spacecraft hardware or mission operations — this guide introduces the spacecraft bus and mission Δv budgeting from the systems-engineering level, not hands-on hardware experience
•Detailed thermal or structural analysis (FEA/CFD-level) — the thermal and structural material here is conceptual/systems-level, matching an actual mission-design phase rather than detailed subsystem engineering
•Any specialized mission-design software beyond what Installation introduces
Time Estimate
If you have the prerequisites above:
•Overview + Fundamentals: 1-2 days
•Intermediate + Advanced: 2-3 days
•Interview-ready (comfortable assembling a full mission Δv budget across launch/transfer/station-keeping phases and explaining why each belongs to a different propulsion system): 4-5 days
Start Here
Go to the Installation section to set up a Python environment for Δv-budget calculations, then work through Overview's full mission Δv budget example yourself rather than only reading it.
