Episode notes
Last-Minute Ground Station Rescue
- Christopher flew to the Azores (Santa Maria) one week into joining the team to set up a ground station for Odin.
- The ground power amplifier broke before launch, forcing last-minute scramble and near-miss backups.
Trillion-Fold Path Loss
- Deep-space path loss is enormous compared with LEO/GEO, on the order of 250 dB which equals ~10^-25 in linear power.
- That attenuation forces fundamentally different RF designs and extreme link-budget thinking.
Aiming Is As Critical As Power
- Ground and spacecraft pointing must be extremely precise because high-gain antennas have very narrow beamwidths (often <<1°).
- Small misalignments produce major additional loss that dominates link performance.
