The Earth and Moon Space Environment
Course Description
As humans venture beyond Earth, the Moon will serve as a crucial gateway for space exploration. This three‑day course introduces the math, physics, and engineering needed to reach, orbit, land on, and sustain life on the lunar surface. Learners will explore concepts essential for developing long‑term lunar colonies, including in situ resource utilization and extraction of raw materials — capabilities that will inform future human missions to Mars and beyond.
1. The Earth–Moon Environment
- Structure of the Earth–Moon system, including distance, orbit, and gravitational interactions
- Overview of the Moon’s geological composition
- Key features of Apollo landing sites and why they were selected
- How Earth–Moon dynamics influence exploration and operations
2. Trajectories to the Moon
- Fundamentals of orbit transfers and energy requirements for lunar travel
- Key flight stages from Earth departure to lunar arrival
- Application of the rocket equation to compute energy needs for injection orbits
- Principles of lunar orbit insertion and gravitational capture
3. Apollo vs. Artemis Mission Design
- Comparison of 1960s Apollo trajectories with modern Artemis I and II flight plans
- Advances in navigation, propulsion, and mission architecture
- Evolution of risk considerations and safety strategies
- Lessons learned from Apollo that inform Artemis mission design
4. Lunar Orbit Dynamics
- The three‑body problem and practical methods used by mission designers
- Einstein’s space‑time framework as a tool for visualizing gravity
- Identification and characteristics of Earth–Moon Lagrange points
- Challenges posed by the Moon’s uneven gravity field (mascons)
5. Operating Spacecraft in the Earth–Moon System
- How gravity variations affect orbital stability and mission planning
- Navigation and station‑keeping requirements around the Moon
- Mission design strategies to maintain safe orbits and transfers
- Operational constraints for crewed and robotic spacecraft
6. Long‑Term Lunar Settlement
- Resource extraction opportunities and required technologies
- Hazards to human presence, including radiation and micrometeoroids
- Criteria for selecting lunar colony locations
- In situ resource utilization (ISRU) and its role in sustainable settlement
7. Returning from the Moon
- Requirements and challenges of Trans‑Earth Injection (TEI)
- Strategies for precise targeting of Earth re‑entry and landing
- Energy, timing, and navigation considerations for return missions
- How return trajectories differ for crewed versus uncrewed vehicles

One PDU = 1 contact hour of instruction (one CEU = 10 PDU)
Upon successful completion of most GTPE courses (80% minimum attendance and a passing grade in courses that require an assessment), you may receive a certificate indicating the number of CEUs earned. Certificate issuance exceptions include courses with outstanding credentialing entities (i.e. OSHA or PADI).
CEUs earned are recorded in the attendee’s name and will appear on a GTPE transcript. All transcripts must be requested by the attendee via the transcript request form. Requests are typically processed within three business days.
For an audit of your transcript for progress toward completion of a certificate, please complete the transcript request form. GTPE courses do not provide academic or degree credit. Georgia Tech academic or degree credit is only available to matriculated students taking courses that meet degree requirements.
For specific information on state licensing or credit requirements, please contact your state licensing board. If you are seeking certification through a professional association, please review the specific requirements with that association.
