--------------------------------------------------------------------
*** After Orion separates from the ICPS ("Interim Cryogenic Propulsion
Stage"), 10 small spacecraft ("CubeSats") will be deployed to perform
experiments and technology demonstrations. Each CubeSat provides its own
propulsion and navigation.
-----
1. The above suggests that during our first visibility we see only a
coasting Artemis-1 rocket. Maybe some telemetry, maybe S-band;
frequency believed to be 2217 ±0.5 MHz, data rate 1 Mbps.
2. AOS 2, our second (long) visibility, begins with the rocket in a
trans-lunar trajectory.
3. About 7 minutes after our AOS 2 Orion and the ICPS separate. Maybe
some Orion telemetry, maybe S-band. 2203.2/ 2216.5/ 2287.5 MHz, ~5Mbps
4. During the next ~90s the Cubesats are ejected. At various times
thereafter (hours?) they will become "live". See published graphic.
5. At this point (20:24:31 utc) some or all could be radio alive.
We then have ~7 hours to unravel the ensuing chaos. Or sleep.
