Exploring the Solar System in 3D: Laser Altimetry, Sample Return Caches & ISRU Habitat Engineering
Modern planetary exploration relies on multi-layered orbital remote sensing—pioneered by NASA's Solar System Treks portal—to transform raw spacecraft telemetry into high-resolution 3D Digital Elevation Models (DEMs). Before a robotic lander, sample-return rotorcraft, or crewed Artemis Starship touches down on another world, planetary geologists cross-reference four critical datasets: topographic elevation, local slope hazard angle, solar illumination horizon, and in-situ volatile/mineral abundance.
How to Use the 3D Planetary Surface Explorer & Habitat Planner
- Select Any of the 6 Solar System Worlds (Top Ribbon): Switch instantaneously between the Lunar South Pole (Shackleton Crater), Apollo 11 Mare Tranquillitatis, Mars Jezero Crater (Perseverance Sample Return), Valles Marineris, Asteroid 101955 Bennu, and Metallic Asteroid 16 Psyche.
- Toggle the 4 Remote-Sensing Science Overlays (Bottom Dock):
- 1. LOLA/MOLA Laser Elevation Hypsometry: Color-codes terrain height from deep basin floors (indigo/cyan) to towering crater rims and central peaks (emerald, gold, and white).
- 2. True-Color Optical Regolith Albedo: Renders authentic lunar anorthosite/basalt, Martian iron-oxide dust, carbonaceous Bennu regolith, or metallic nickel-iron Psyche craters.
- 3. Landing Hazard Slope Map: Highlights flat, safe touchdown ellipses (<8° slope) in green and dangerous boulder/scarp slopes (>15°) in warning red.
- 4. Neutron Spectrometer H2O Ice & Metal Map: Reveals hydrogen-rich water-ice cold traps in violet-blue and ilmenite/metal ore concentrations in amber.

Planetary Gravity, Solar Irradiance, Radiation Shielding & ISRU Stoichiometry
g = (G · M) ÷ R², v_esc = sqrt( (2 · G · M) ÷ R )
2. Inverse-Square Solar Flux S(r) & Photovoltaic Power Output P_solar at Heliocentric Distance r_AU:
S(r_AU) = 1361 W/m² ÷ (r_AU)², P_solar = S(r_AU) × A_panel × η_cell × sin(θ_sun)
3. Galactic Cosmic Ray (GCR) Dose Attenuation Through Regolith Shielding Thickness z (m) of Density ρ (g/cm³):
X_areal = z_m × ρ_regolith × 100 [g/cm²], Dose(z) = Dose_0 · exp( -X_areal ÷ λ_attenuation )
4. Lunar Ilmenite Reduction & Mars MOXIE Solid-Oxide CO₂ Electrolysis Stoichiometry:
• Moon Ilmenite: FeTiO₃ + H₂ → Fe + TiO₂ + H₂O, 2 H₂O (electrolysis) → 2 H₂ + O₂ ↑
• Mars MOXIE: 2 CO₂ (g) → 2 CO (g) + O₂ (g) ↑ (Requires ~0.84 kg O₂ per astronaut per day)

Built-In NGSS / STEM Educational Lesson Plans & Lab Exercises
Lesson 1: Artemis III Landing Site Selection
Objective: Select 1. Moon: South Pole and switch between the Slope Hazard Map and Neutron H2O Ice Overlay. Identify a landing zone with a slope under 8° that sits within 2 km of both a sunlit solar ridge and a violet PSR ice deposit.
Lesson 2: Mars Sample Return Traverse Planning
Objective: Load 3. Mars: Jezero Crater and click the 4 Perseverance waypoints from the crater floor igneous lava units through the Three Forks Sample Depot to the western carbonate margin to reconstruct the ancient lake's habitability timeline.
Lesson 3: Designing a Radiation-Safe Habitat
Objective: Deploy 2 Hab Domes, 3 Solar Arrays, and 2 Ice-Mining Rigs on Mars or the Moon, then adjust Slider #3 (Regolith Shield Thickness) until annual crew cosmic radiation drops below NASA's 20 mSv/yr design target.
