What's New
Signal Propagation Delay Visualizer
New animated panel in Mission view showing:
- One-way and round-trip light time
- "Transmit now → arrives at" and "Seeing telemetry from" timestamps
- Animated pulse traveling between Earth and spacecraft (~2.5s loop)
Ephemeris Range Fallback
When DSN doesn't provide RTLT data, the app now fetches range and light-time from JPL Horizons:
- Uses the actively tracking DSN complex as the observer
- 60-second cache per (spacecraft, complex) to avoid rate limiting
- Ephemeris estimates shown in muted purple with source indicator
