HALO Mars: Hazard Aware Layered Operations on Mars

HALO Mars Hazard Aware Layered Operations on Mars

POSITION Suit Grid Position: Live (GX, GY) cell inside the 150×150 (`10 km × 10 km`) terrain matrix and straight-line distance from Base Habitat `(75, 75)`. GX 85, GY 65 • 0.95 km

ELEV / RAD Elevation & Dose Rate: MOLA/HiRISE altitude (m) and live radiation dose rate (µSv/hr) shielded by surrounding canyon horizon (SVF). -2180 m • 8.9 µSv/hr

SOLVER Physics Compute Time: Wall-clock time (ms) to solve unabridged 8-connected Dual-Pass Dijkstra across all 22,500 cells plus Marching Squares contours. 3.1 ms

ZERO-GPS Zero-GPS Horizon Lock: Correlation confidence (NCC %) and optical compass heading comparing the suit camera skyline against orbital Mars elevation data. Click readout to inspect. 99.9% • Yaw +0°

Safe Zone Caution Turn Back (Red) Return Route Safe Return Contours:
• Safe Zone (Green): T < 0.75 — ample outbound + return reserve.
• Caution (Amber): 0.75–1.00 — approaching turnaround ceiling.
• Turn Back (Red): T > 1.00 — reserve deficit to reach Base safely.
• Return Route (Blue): Energy-optimal path around cliffs & drift sand.

HiRISE: Rust/Ochre Relief • Red = >33° Impassable Cliffs

Burn: -- kcal/hr O₂: -- kg • Batt: -- Wh

Wrist Watch & Battery Saver:
• Shows your mission timer, remaining O₂ and battery rings, and an orange Home dot on the outer bezel pointing straight back to Base.
• 1Hz Battery Saver (Eco Mode): Pauses the 3D map graphics (0 mW GPU) and updates the watch screen once per second—stretching battery life from 2.8 hours to 15.6 hours on a single coin-cell battery during an emergency.

60Hz 3D • 231.9 mW • 2.8 HRS

EVA & ROUTE TELEMETRY

Heart Rate Crew Heart Rate (BPM): Drives effective cardiovascular strain (`%HRR`) and NASA-STD-3001 triage multiplier above 75% HRR, shrinking the safe return perimeter under high exertion. 88 BPM

Suit + Sample Load Suit + Collected Mass (kg): Combines 50 kg suit mass + collected rocks added to the `82 kg` crew mass in partial gravity (`3.71 m/s²`), raising uphill and sand-slip work. 65 kg

Calorie Reserve Usable Metabolic Reserve (kcal): Total mission energy budget minus a mandatory 250 kcal safety buffer. Lowering reserves shrinks the green/amber safe return contour immediately. 750 kcal

Simulate Field Sampling: Adds +15 kg to Suit + Sample Load (up to `120 kg`) so you can test whether carrying heavier geological cores keeps your return corridor safe.
