Episode notes
Deep Space Requires Exotic Ground Hardware
- Deep-space ground comms reuse core radio components but require far more sensitive, cooled amplifiers and rare infrastructure.
- That scarcity and sensitivity makes deep-space links qualitatively different from near-Earth satellite comms.
Scheduling Passes Before Separation
- After separation we pre-schedule antennas by computing where Earth will need to point to see the spacecraft.
- We call each scheduled window a "pass" and book contacts in advance because antenna time is limited.
Competing For The Same Beam
- Odin launched as a rideshare with several other spacecraft, so many teams competed for the same ground assets simultaneously.
- That competition left AstroForge without priority access to the primary dishes during critical early passes.
