SpaceX F9 - Eutelsat 10B - CCSFS SLC-40 - 22/23 November 2022 (02:57 UTC)

The next SpaceX Falcon 9 rocket will launch the Eutelsat 10B communication satellite from pad 40 on November 21 at 9:52-10:02 p.m. EST.

Only a 10-minute launch window. Isn't that unusual for a GTO launch?

Wider launch window > using performance that could otherwise be dedicated to reducing the delta-v needed to reach GEO from the transfer orbit.

They are already using an expendable 1st stage.

They are already using an expendable 1st stage.

So why is the performance loss acceptable on the other GTO missions that have longer windows?

Falcon 9 uses subcooled propellants.  I think that might be the main reason they want short launch windows.  The spacecraft people would probably be happy with their usual 1-2 hour window duration.

For GTO launches, they try to hit a specific point in space. The optimal launch time to reach that point is always the middle of the launch window. However, they are able to extend that launch window by using the margin the launch vehicle has to steer into the optimal trajectory (ULA calls it RAAN steering). That takes a little bit of performance. In the case of Eutelsat 10B, which already is an expendable launch due to performance requirements, that margin is very small which only allows for a 10 minute launch window.

Can anyone post here the mission patch, please? At least from Eutelsat side.

I checked https://www.spacex.com/launches/eutelsat-10b/ and it was actually updated. SpaceX has the T-0 as 02:57 UTC.

SpaceX support ship Doug is an impressive 1015 km (549 nm) downrange to recover the fairing for the upcoming Eutelsat-10B mission.

Booster B1049 will be expended.

Targeting Monday, November 21 at 9:57 p.m. ET for a Falcon 9 launch of the Eutelsat 10B mission from SLC-40 in Florida → spacex.com/launches

https://www.spacex.com/launches/eutelsat-10b/

SpaceX is targeting Monday, November 21 for launch of the Eutelsat 10B mission to a geosynchronous transfer orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 9:57 p.m. ET (02:57 UTC on November 22). A backup launch opportunity is available on Tuesday, November 22 at the same time.

The Falcon 9 first stage booster supporting this mission previously launched Telstar 18 VANTAGE, Iridium-8, and eight Starlink missions.

A live webcast of this mission will begin about 15 minutes prior to liftoff.

Tonight @SpaceX will retire another booster, the B1049. The B1049 has already made 10 launches and is the booster that has been "stopped" the longest.

Weather permitting, Falcon 9 B1049 will make its final flight this evening. Eutelsat-10B is set to be deployed into a supersynchronous transfer orbit, lifting off from SLC-40 at 9:57 PM EST (02:57 UTC).

Falcon 9 could loft a 4.5 tonne satellite to supersynchronous transfer orbit with first stage downrange recovery.  Why expend a stage here?  Is the orbit substantially higher energy, or does the satellite weigh more than suspected?

My opinion is it’s a way higher energy orbit.

Maybe apogee might be between 80,000 and 90,000 kilometers and the inclination close to 21 degrees.
