There is not much to separate the telemetry for SXM-7 and SXM-8. The biggest difference I see is that the SXM-8 second stage flew with a bit more loft, but to the same injection parameters.

Ken the Bin noted earlier that the updated timeline showed the fairing deployment some 14 seconds earlier on SXM-8 compared to SXM-7. Maybe the increased lofting allowed the earlier fairing deploy? I wonder if that helps with fairing recovery by reducing re-entry velocity?

There is no sound insulation cotton on the fairing

Didn't pay attention to that detail. Good catch.

Indeed, usually its only Starlink missions that omit the acoustic tiles. There is nothing preventing other satellites though from being made compatible with that same acoustic environment though. It does save mass

But why else do Starlink missions eliminate the acoustic tiles besides shave off dry mass?

They're porous so probably absorb water after landing, requiring a lot of time to remove, clean, and replace with new insulation. Also more weight in the fairing (especially when waterlogged) increasing risk of damage when lifting/transporting.

The SXM-8 radio broadcasting satellite has been cataloged in a sub-synchronous transfer orbit of 235 x 19384 km x 27.0 deg. The heavy 7 tonne satellite is mostly propellant and will use its own engine to first raise apogee and then perigee to GEO altitude (~35800 km)

Another contributing factor could be that they have been collecting data on the Starklink missions and now know that the extra acoustic tiles are unnecessary - at least for this kind of payload.

100th Falcon 9 v1.2 launched, and 100th success. A 101st v1.2 was lost with AMOS 6 in the 2016 pre-static firing propellant loading explosion at SLC 40.

JRTI and B1061 will be within the vicinity of Port Canaveral from around midnight tonight. They can than set up for an arrival around dawn tomorrow.
OCISLY droneship is currently occupying the parking space for JRTI so needs to be moved or depart before JRTI arrival can happen.
