Mission Design and Orbital Mechanics Engineers compute every delta-v maneuver, select launch windows, and plan the entire journey from parking orbit to final destination — whether that is geostationary orbit, the lunar surface, or a comet rendezvous a decade away. Using tools such as GMAT, STK, and Python astrodynamics libraries, they balance the physics of gravity, propellant mass, and launch vehicle capability against programmatic constraints like planetary alignment and mission lifetime. This is the discipline that chose July 2015 for New Horizons' Pluto flyby a full decade in advance.
Core curriculum must include classical mechanics, orbital mechanics (two-body problem, Kepler's laws, patched conics), numerical methods, and linear algebra. Electives in celestial mechanics, space mission analysis (Bate/Mueller/White 'Fundamentals of Astrodynamics' is the canonical text), and control theory lay the foundation. Participation in a university rocketry or CubeSat team with orbit planning responsibilities is highly valued.
Graduate research on specific trajectory problems: optimal control for low-thrust transfers, invariant manifold trajectories in the three-body problem, or high-fidelity force model integration. A master's at UT Austin, CU Boulder, or TU Delft is frequently sufficient; a PhD is the typical path into JPL's Mission Design and Navigation Section (Section 312). Key tools learned: GMAT (NASA open-source), STK/Astrogator (AGI/Ansys), MATLAB with Aerospace Toolbox, and Python libraries (Poliastro, Orekit).
First operational role involves supporting trajectory design for a specific mission phase: launch window analysis, orbit maintenance delta-v budgeting, station-keeping for GEO satellites, or re-entry corridor analysis. Produce trajectory design documents and interface with the propulsion team to validate delta-v margins. At JPL, new hires join the Outer Planets mission teams or the Interplanetary Mission Design group.
Own the mission trade space for new concepts: evaluate launch vehicle options, compute trajectory architectures (direct, gravity assist, low-thrust), and produce the delta-v budget that constrains spacecraft mass. Present findings to program management and NASA HQ. At ESA ESOC Mission Analysis Section, this role produces the mission analysis report (MAR) that is the foundational document for all subsequent engineering.
Responsible for the full mission design through launch, on-orbit, and decommission. Interface with navigation team for orbit determination and maneuver planning. Develop new trajectory design algorithms, mentor junior analysts, and represent the program on trajectory-related risks. Some transition into flight dynamics operations roles at ESOC (Darmstadt) or GSFC, executing real-time maneuver commands.
US-centric estimates. International compensation varies; agency-civilian roles tend to cap lower, commercial roles higher.

USMA West Point BS → Korean War combat pilot → MIT ScD 'Line-of-Sight Guidance Techniques for Manned Orbital Rendezvous' (1963) → NASA Group 3 (1963) → Gemini 12 EVA → Apollo 11 Lunar Module Pilot. Aldrin is the archetype of mission design expertise turned into spaceflight: his doctoral thesis directly solved the rendezvous problem that made the Apollo lunar mission concept viable.

The hardest part
The mission design is locked in years before launch, and if you made an error in your delta-v budget or launch window computation, discovering it during a critical maneuver is catastrophic with no recovery. The entire program depends on your calculations being right the first time. Beyond that, this discipline demands maintaining expertise in both the deep mathematics (differential geometry, Hamiltonian mechanics) and the practical engineering constraints (propellant margins, tracking station coverage, launch vehicle performance dispersions) simultaneously — and the field is small enough that there are very few senior mentors outside of JPL and ESOC.
Employers and agencies hiring for this role outside North America.
