I think sun synchronous orbits are retrograde P2P sub orbital hops are either direction, 30-40 minutes, maybe 25 for shorter trips like London to New York.

- gpm 7y agoAgreed that P2P sub orbital hops are any direction. Low sun synchronous orbits are approximately the same as polar oribts, more perpendicular than retrograde. I'm not sure if we use high sun synchronous orbits for anything?
- isostatic 7y agoSun sync is approx 98.7 degrees at 800km - so slightly retrograde (prograde being 0-90) Majority of LEO sats are sun sync
