T-20 minute vent. Launch appears to be a go.
Screencap from SFN webcast.

Liftoff! And first stage ascent.

5th and 6th fairing flights for those interested.

MECO > Stage 1/2 separation > SES-1 > fairing separation.

Second stage accelerates towards initial orbit; first stage ballisticly coasts to apogee.

zubenelgenubi · « **Reply #45 on:** 08/19/2022 07:27 pm »

First stage reenters atmosphere, with entry burn; second stage continues to accelerate.

First stage landing burn and successful landing.

SECO-1 > initial orbit achieved.

End of webcast.

Stack separation confirmed on the audio channel.

Actually, no, not at all. Still watched every second until landing and orbital insertion. Congrats AGAIN, SpaceX.

( Spike it all the way to Spica, if you must.

Satellites separations confirmed on mission control audio channel. Public access removed immediately following, as per usual.

Congratulations to the entire launch campaign team!

Seemed like a quite short entry burn (about 17 seconds). Normally it's more like 20 seconds.

I wonder if the entry burn is variable depending on the performance of the first stage. In theory MECO could happen at the desired velocity, then the entry burn starts at the specified altitude, and concludes when there is just enough fuel left for landing. This would lead to a variable entry burn - if the first stage over-performs, then the entry burn is longer, for less wear and tear on the booster. Conversely, if the first stage has to work harder than usual, then the entry burn is shorter. That's extra heating on the booster during the aerodynamic deceleration, but better than running out of fuel during landing.

Falcon 9 B1062 completes its ninth mission, with touchdown on SpaceX drone ship "A Shortfall Of Gravitas (ASOG)" - the 63rd (!!) consecutive successful landing.

Epic views all the way down again!

That’s just business as usual on the Space Coast!

Most of these folks didn’t know when they set out for the beach that they’d be treated to a Falcon 9 launch. That’s what I call winning the vacation lottery!

You can’t see SLC-40 from Cocoa Beach, but it turns out you can see the exhaust plume shooting out the right side.

3, 2, 1… liftoff!

At 3:21 p.m. EDT today, Falcon 9 B1062 launched from SLC-40 with 53 Starlink satellites headed to orbit.

In the foreground, B1073 stands Port Canaveral after its launch of 52 Starlink satellites earlier this month.

Falcon 9 second stage S-band downlink over Europe, 20 minutes after start from Cape Canaveral. Received with HackRF + Nooelec LNA + 5,5 turn helix on 100cm mesh dish..

150th Falcon 9 v1.2 orbital success. Accomplished using 44 42 first stages, about 12 of which are still apparently flyable.

List of active F9/ FH side boosters with their current designation:

B1049.11
B1051.14
B1052.7 (Flew twice as FH side booster, will return to that status later on)
B1053.3 (FH side booster)
B1058.14
B1060.14
B1061.11 West Coast
B1062.10
B1063.7 West Coast
B1067.6
B1069.2
B1071.5 West Coast
B1073.4

A dozen boosters in F9 configuration and expected to fly again in that configuration. 1 flight proven FH side booster.

There are also 10 boosters known to exist but that have not yet flown. 4 FH side boosters (B064, B1065, B1072, and B1075) and 4 FH core boosters (B1066, B1068, B1070, B1074) One booster has an unknown configuration, and there is 1 F9 booster set to fly Crew 5 to the ISS.
