Santa Fe, New Mexico
Launch Date: November 22
Launch Window: 9:57pm EST (6:57pm PST, 02:57 UTC on the 21st) 2 hour window
Launch site: SLC-40, Cape Canaveral Space Force Station, Florida
Core Booster Recovery: N/A
Booster: B1049.11 (will be expended)
Fairings: Reused likely
Mass: 4500 kg (9921 lbs.)
Orbit: GTO
Yearly Launch Number: 53rd

Booster B1049.11 will be expended as part of this launch. It will be launched without legs or grid fins. It will have a white interstage instead of the typical black one from a Block 5. The interstage is from B1052 Falcon Heavy side booster that was converted to a standard F9 booster.

A SpaceX Falcon 9 rocket will launch the Eutelsat 10B communications satellite for Eutelsat. Based on the Spacebus Neo platform built by Thales Alenia Space, Eutelsat 10B will provide maritime and in-flight broadband, data, and video connectivity to customers in the Americas, the Atlantic Ocean, Europe, Africa, the Middle East, and Central Asia.

The payload was originally supposed to be launched on an Ariane 5. It is the last of the three Eutelsats (the Hotbirds were the other two) that moved from Ariane over to SpaceX for launches this year. The delay of the Ariane 6 rocket and potentially the war in Ukraine caused the switch.

From a SpaceX perspective it is rather nice that their customers for the 3 expended Falcon 9s are effectively paying SpaceX to upgrade part of their operational F9 fleet. Do we know if all 3 will be replaced?

SpaceX is building about 6 boosters a year out of the Hawthorne factory. They currently have 14 active F9 boosters until losing B1049 tonight. They also have 9 somewhat inactive FH boosters and cores waiting on launches.

Every launch needs a second stage and Vacuum Merlin. So they are cranking out about 60 of those a year now.

So the reality is that 6 boosters are using all 60 of those second stages with the ease SpaceX is having boosters do 10+ launches now.
 
Weather isn't good.

How many times has B1049.11 launched before?
10. It is also a pretty old block 5, so might not have been built as robustly as newer block 5s, but that’s just speculation on my part.
Just a reminder, that early Block 5's did not have the inconel COPV tanks demanded by NASA after the Amos-6 anomaly and spectacular failure. B1051 was the first booster to get the new COPVs. As far as I am aware, B1049 has the COPVs that are just COPV without the inconel "liner".
 
Everything is nominal. Launch, MECO, Stage Separation, Non-landing of the booster, Second stage restart, one minute boost, SECO2, and just waiting on payload deployment. I expect that will go well. 35,840 km per hour at SECO2 and 311 km altitude. We'll see what the speed and deployment altitude ends up being.

33050 km per hour and 1275 km altitude for deployment.

Nice job SpaceX!!
