Task 150: EP03 On-Screen Data Extraction

Status: DONE

Motivation

Extending video frame analysis from EP01-02 (Tasks 146, 148) to EP03.

EP03 covers Enceladus departure → Titania arrival (143 hours).

Key Findings

DESTINATION: U-3 Titania Terminal Complex (U3-TTC)
ARRIVAL ETA: T+143:12:00 (PORT STD TIME) — matches dialogue exactly
NAV MODE: SATURN-REF > SOL-INERTIAL > URANUS-REF (Scheduled)
Route name: SOLER LINE — the series title is the route name!
ORB-CURTAIN BOUNDARY CROSSING DETECTED — legal risk acceptance warning
Ship ID: MTS-9907/EXT-P17, Ship marker: MTS-9907-E01

6-Phase Burn Sequence (most detailed of any episode)

Saturn Escape: Δv=4.31 km/s, T+00:00, Duration 0:10:10 (green)
Cruise Burn: Δv≈2.99×10³ km/s (=2990 km/s), T+03:30, Duration 30:25:00 (green)
Exoplanar Alignment (RCS Trim): Δv=0.11 km/s, T+47:00, Duration 0:18:00 (red)
MCC-1 (RCS Trim): Δv=0.05 km/s, T+71:00 (red)
MCC-2 (RCS Trim): Δv≈0.07 km/s (partially obscured) (red)
Capture Prep: Δv≈2990 km/s, Duration 30:25:30 (red)

Brachistochrone confirmation: Cruise Burn (30:25:00) ≈ Capture Prep (30:25:30)!

PLASMOID STORM Warning

EST T+138:00:00 — predicted 5 hours before arrival, foreshadowing EP04

SOLUTION A: Star Tracker Reference, Confidence 92.3%
SOLUTION B: Inertial Guidance Reference, Confidence 91.7%, Last Correction: -21min
DIFF/ENT: 1.43×10^7 [km] = 14,300,000 km — matches dialogue 1436万km (0.4% rounding)
Two diverging trajectory lines visualize the crisis

Uranus Approach

Altitude 25 RU at magnetosphere entry
NAV reference switch: SOL-INERTIAL → URANUS-REF
