We don't know a lot of details about Inspiration4's mission yet, so a lot of guesswork & I'll be updating as we get that info next week. Jared Isaacman indicated an interest in launching in the pre-dawn hours for spectacle, so I've put the launch time at ~10:30 UTC. B1062 is confirmed, and so is Resilience. Guess is an initial ~200x575 kilometer orbit, raised to 575x575km.
For the first polar Starlink mission (Starlink v1.0 P1), the ASDS and FRV positions have been posted on the General SpaceX Map: Starlink v1.0 P1 Recovery Locations
OCISLY Position: Lng.-117.849722 Lat.29.375556
FRV Position: Lng.-117.657826 Lat.28.985422
Don't really know what the initial azimuth will be before a dogleg is performed after stage separation. Also, I assume the parking orbit apogee would be around 300 km given the final orbit will be at 570 km.
I saw on Gunter's Space Page's "Orbital Launches of 2021" that the website's author guessed 40 Starlink sats per polar mission. This adds up to a total mass of 10.4 tons compared to 15.6 tons (60 Starlink sats).
Still working on this... can't seem to figure out DART's launch trajectory. Any tips? I have it in a 64.7 inclination orbit at SECO, 200x300 km. I know there's a dogleg but I don't know the initial launch inclination to put F9 on to reach OCISLY. Falling behind as SpaceX already has another launch geared up this week.
