Task 151: EP04 On-Screen Data Extraction
Status: DONE
Motivation
Extending video frame analysis to EP04.
EP04 covers Titania → Earth return, with 65% thrust limitation, plasmoid encounter
(480 mSv), and security fleet pursuit. On-screen displays may reveal navigation
parameters for this return journey.
Key Findings
TRAJECTORY PREDICTION — Plasmoid Zone Parameters (02:38-02:45)
The most scientifically detailed display in EP04, showing real-time environmental monitoring:
Orbital Trajectory
- Periapsis Altitude: 6.50 RU
- Intercept Velocity: 18.3 km/s
- Vector: 2.1° INC / AZM 110.8°
- U3-Titania Approach: T+9h
- Advisory Index: CRITICAL
Plasmoid Zone (Estimated)
- Magnetic Field: 180-340 nT
- Plasma Density: 0.8-2.3 cm⁻³
- Core Temperature: 2.1×10⁶ K
- Traverse Time: 00:08:00
Shield & Operational Constraints
- Shield Capacity: 63% (12H TO CRITICAL)
- Shield Remaining Lifetime: 14 min
- Margin: 6 min (14 min life − 8 min traverse)
- Burns Remaining: 1-2 MAXIMUM
- Navigation: CS > INERTIAL (BEACON UNAVAIL)
Ship Status
- Cooling System: 0.74 MPa (63% of specification)
- Nozzle Burnout Probability: 67% on next ignition
- Cumulative Radiation: 480 mSv (dry patch reading)
- Engine Output: 65% (thrust 6.3 MN)
Location Labels
- 天王星エントリー軌道 / 天王星自由港機構 / タイタニア自治圏
- New jurisdiction "タイタニア自治圏" — more specific than EP03's "天王星圏"
Narrative Moments
