Task 155: EP05 On-Screen Data Cross-Reference with Orbital Analysis

Status: DONE

Motivation

Task 154 extracted on-screen data from EP05 video frames — the most detailed route

plan display in the series, with 4 burns (Uranus Escape, Jupiter Flyby, Mars Decel,

Earth Capture), exact ΔV/duration values, and LEO arrival parameters.

This task cross-references those on-screen values against the existing EP05 orbital

calculations, Rust crate analysis, and report data. This completes the cross-reference

chain across all 5 episodes (Tasks 147, 149, 152, 153 covered EP01-04).

Scope

1. Compare on-screen ΔV budget (4200 km/s total) with existing EP05 calculations
2. Verify burn durations against brachistochrone parameters at assumed masses
3. Cross-check Jupiter flyby parameters (exit velocity 2100 km/s, INC 31.47°)
4. Validate Earth LEO 400km arrival conditions
5. Check nozzle thermal margin (+0:26:00) against existing nozzle analysis
6. Examine navigation mode (STELLAR-INS AUTONOMOUS) implications
7. Create ep05_onscreen_crossref.json with findings
8. Add exploration to EP05 report
