Congratulations on the first 7th flight for an external customer.  The booster performed really well. 

Seems this beast of a payload could have almost gone on a FH. 

Fingers crossed on fairing recovery. 
Starship, Vulcan and Ariane 6 have all reached orbit.  New Glenn, well we are waiting!

Shortly afterward, SXM-7 deployed its solar arrays and started receiving and sending signals. Next, SXM-7 will begin firing its thrusters to commence its journey to its final geostationary orbit.

A #SpaceX #Falcon9 left earth Dec 13 on a mission to deliver #SXM7, a radio satellite for @SIRIUSXM. This is the second time @SpaceX has launched a Falcon 9 for the seventh time. #B1051 flight heritage: #Demo1, #Starlink missions, #RadarSat (RCM) & #SXM7.

The #Falcon9 takes to the skies for the 7th time on its way to successfully deliver #SXM7 to orbit! The booster landed & will now be brought back to Port Canaveral for refurb & its next mission. That's now 25 launches for the #SpaceX
Falcon 9 this year!
Covered for @Teslarati

Initial orbit for 2020-096A: 237 x 19389 km, 27deg
Very similar to the Telstar 18V and Telstar 19V missions, which were from the same manufacturer.

Here is a comparison between the SiriusXM-7 and ANASIS-2 mission telemetry.

ANASIS-2 was unusual because it injected to a nearly circular parking orbit, presumably to take advantage of the Oberth effect for the second S2 burn at an altitude of 182km. For whatever reason, SXM-7 marks a return to a more elliptical parking orbit, with the burn to medium earth orbit commencing at a more conventional 241km altitude.

My estimate for apogee was 19515.7 km, so I was off by only 0.65%!

The higher altitude might be because SXM 7 went into sub-GTO. Its next burn would be at perigee, so you want to make sure you're well above the atmosphere so that you don't accidentally re-enter from air drag if you have to delay the burn.

JRTI droneship is now underway from the SXM-7 LZ, towards Port Canaveral.

Ms. Tree is due to arrive in Florida early tomorrow morning (15th) - likely before dawn. GO Searcher is due back later in the day.

Ms. Tree has just returned from the SXM-7 mission with an intact fairing half that was recovered from the water!

I can’t tell you much other than there is a fairing half there. Can’t tell what kind of shape it’s in.

I don't think this has been mentioned before.

This launch marked the fastest fairing turnaround at 146 days between ANASIS-II and SXM-7. Previous record was 154 days between two Starlink launches.

Edit: Actually, this is incorrect. The record turnaround was between Starlink L8 and L13 at 127 days. SXM-7 was the second fastest so far.

GO Searcher has arrived at Port Canaveral with a fairing half (under the blue tarp) that was recovered from the water during the SXM-7 mission!

Expect to see a rapid turnaround and to leave for NROL-108 as soon as tonight.

JRTI droneship and Falcon 9 are currently set to return to Port Canaveral on Thursday 17th, shortly after dawn.

GO Quest has elected to charge on ahead, not wait with JRTI. Quest came straight from the CRS-21 operation so has been at sea for two weeks.
