First stage landing and second stage attains orbit.

Second stage coasts > SES-2 > spacecraft separation.

Congratulations to the entire launch campaign team!

And thank you, NSF webcasters, for a great show. 👍

Falcon 9 soars through the sky on its way to deliver SES-22 to geostationary transfer orbit.

Booster B1073 landed successfully for its 2nd time.

The cloudy backdrop made for a gorgeous liftoff, and the atmospheric conditions created a longer-lasting vapor cone.

SES-22 Mission Control Audio

Well, they switched that YouTube feed to private or deleted it. Was there a new one? It's not showing up in their YouTube channel, although they usually hide it after the launch (instead of deleting it) . I wanted to watch the ground track move during the inclination plane change burn.

CelesTrak has GP data for 1 object from the launch (2022-071) of SES-22 on a Falcon 9 rocket from Cape Canaveral on Jun 29 at 2104 UTC:

16.54deg, 310 x 35,627km
About GTO-1600

People always seem to be curious about how loud launches get. Well, here's how loud today's launch of SES-22 was from the press viewing about 3 miles away.

The ΔV requirement for the plane change from 28.5° to 16.5° in LEO is about 1,580m/s. With a payload mass of only 3.5t there was plenty of performance available to not only achieve GEO-1600, but to perform this simultaneous dogleg, which is apparent in the attached before and after stills from the webcast.

Although there were a couple of video stutters on re-entry, the telemetry data was solid, as you can see from the attached plots.

Fun fact, SES ordered six C-band satellites (2 each from Boeing, Northrop and Thales Alenia Space), but the TAS spacecraft were supposed to be "“contingency satellites.” Instead TAS is first in line to launch as SES clears spectrum for a ~$4 billion payout. (1/2)

At the time of the contract award (August 2020), SES was under pressure to "buy American," and really downplayed the TAS satellite order as a backup deal. But TAS finished SES-22 in less than 22 months, which is pretty impressive for a GEO satellite, esp. w/ supply chain issues.

Which drives home an important point: I've been hearing for the past year that European satellite manufacturers are outperforming their U.S. competitors. SES-22 is another indication that Europe is excelling at GEO satellite builds.

Ok this is a longer thread than planned, but that's life.

Here's a link to an article about when Thales Alenia first won this contract. SES didn't even issue a press release at the time because they were only hyping up U.S. contracts. End 🧵.

Is it me or was that booster landing particularly soft this time? Maybe with the incredible quality of video feed it just looks better than before, but that little slide at the end with the legs barely touching tells me that the touchdown was very soft.

With Starlink 4-19 there was a major step up in telemetry and video integrity for ASDS landings, courtesy of the Starlink network itself. The feed is now often as smooth and consistent as the RTLS landings.

SES-22 cataloged as 52933 in a 310 x 35627 km x 16.5 deg geotransfer orbit.

I noticed that too. IMO it's just the greatly improved video quality. But also variability in ASDS vertical elevation (i.e. riding the waves) probably worked out on this one to make for a perfect landing.

People always seem to be curious about how loud launches get. Well, here's how loud today's launch of SES-22 was from the press viewing about 3 miles away. (embedded Tweet)

For the record, the video showed mostly high 90s dBA with a couple peaks at 106 dBA.
