Artemis II Mission Tracker

Real-time mission control dashboard for NASA's Artemis II crewed lunar flyby mission. Live at artemis.cdnspace.ca

Created by Canadian Space

Features

Telemetry & Tracking

• Live MET (Mission Elapsed Time) clock with UTC
• Real ephemeris orbit map (JPL Horizons + NASA/JSC OEM data) with fullscreen mode and real-scale toggle
• Moon detail zoom inset with dynamic zoom, real-position projection, and lunar ground track labels
• Earth detail zoom inset for re-entry approach with splashdown zone
• Orbital telemetry: speed, Moon-relative speed, G-force, altitude, Earth/Moon distance, periapsis/apoapsis
• Inline sparklines for all key metrics (24h history)
• Speed units: km/h, m/s, mph, knots — distance units adapt automatically

Spacecraft Health

• NASA AROW real-time telemetry (1 Hz): attitude quaternion, Euler angles, angular rates
• 3D attitude indicator (Three.js wireframe Orion model)
• RCS thruster activity map with recent-firing indicators (5-min amber fade)
• Solar array wing gimbal angles (inner/outer) with sun-facing efficiency bars
• Solar power estimate from SAW efficiency
• Gyro cross-check (primary vs fallback IMU deviation)
• Dead-band indicators on angular rates
• Signal light time display
• Spacecraft mode decoder

Communications

• Deep Space Network live dish status with country flags (🇺🇸🇪🇸🇦🇺)
• DSN bandwidth chart (30-min rolling, per-dish breakdown)
• Ground station handoff predictions with elevation angles
• Signal light-time delay

Dedicated Pages

• /dsn — 3D globe with NASA Black Marble night texture, real-time day/night terminator, signal beams, station visibility forecast, 24h signal timeline, bandwidth chart, all-dishes view with az/el polar plots
• /stats — Cumulative mission statistics (max speed, max Earth distance, closest Moon approach, total distance, space weather)
• /track — Ground track map (Leaflet + OpenStreetMap/CARTO)
• /api-docs — Full REST and SSE API documentation
• /admin — Protected admin panel for live status updates

Mission Context

• Crew activities timeline (Gantt chart) synced with jakobrosin/artemis-data
• Apollo 8 historical comparison panel with event-by-event context
• Wake-up songs panel (continuing the Apollo/Shuttle tradition)
• Δ-V budget tracker (ESM post-TLI maneuver accounting)
• Space weather (NOAA SWPC: Kp index, X-ray flux, proton flux, radiation risk)
• Next milestone countdown
• Crew bios and spacecraft specifications

Customization

• Panel visibility modal (press M) — toggle any panel or top bar item
• Save/load layout presets with column placement (left/center/right)
• Bilingual: English and French (full i18n coverage)
• SIM mode — replay the mission from archived snapshots with playback controls
• GDPR-compliant cookie consent (GA only loads after acceptance)

Tech Stack

• Next.js 16 (App Router), TypeScript
• HTML Canvas (orbit map, Gantt timeline, sparklines)
• Three.js (attitude indicator, DSN globe)
• Leaflet + OpenStreetMap/CARTO (ground track)
• better-sqlite3 (telemetry archive, WAL mode)
• Server-Sent Events for real-time updates
