Task 154: EP05 On-Screen Data Extraction

Status: DONE

Motivation

Extending video frame analysis to EP05 (final episode). EP05 covers the Uranus→Earth

return with composite route (507h), LEO 400km arrival, and nozzle destruction.

This completes the on-screen data extraction across all 5 episodes.

Key Findings

Complete Route Plan (frames 003-006)

• 4 burn sequences all displayed on-screen with exact parameters
• Uranus Escape: Δv=1500 km/s, T+00:00, D=25:26:00
• Jupiter Flyby: Δv=+600 km/s, T+375:00, D=12:12:00
• Mars Deceleration: Δv=-600 km/s, T+450:00, D=15:16:00
• Earth Capture/LEO Insert: Δv=-1500 km/s, T+479:00, D=27:44:00
• Total ΔV: 4200 km/s, Total burn: 80.6h, Coast fraction: 84.1%
• NOZZLE THERMAL LIMIT MARGIN: +0:26:00

Jupiter Powered Flyby (frame 012)

• Exit velocity: 2100 km/s (entry 1500 + flyby 600)
• Exit vector: INC 31.47° / AZM 261.88°
• Target: Mars Decel Burn
• Io Torus exposure: <6 min

Navigation Mode (frame 003)

• STELLAR-INS — AUTONOMOUS (FULL ROUTE)
• ALL BEACON-GUIDED MODES: UNAVAILABLE
• 507h ship time ETA

Jurisdictional Zones (5 transitions)

• 天王星自由港機構 / 天王星圏
• 国際連合・火星自治連邦保護領 / 土星圏
• 木星軌道連合 / 木星圏
• 地球軌道港湾機構 / 自由圏 (NEW category)

Earth Arrival (frames 020-022)

• Remaining Δv: 10 km/s → orbital velocity achieved
• LEO 400km over Philippines/SE Asia
• Nozzle destroyed after orbit insertion

Changes Made

• Added EP05_KEYFRAMES (23 timestamps) to ts/src/extract-frames.py
• Extracted 23 frames to raw_data/frames/ep05/
• Created reports/data/episodes/ep05_onscreen_data.json
• Added onScreenDataExploration (ep05-exploration-04) to EP05 report
• Updated Task 154 status to DONE

Dependencies
