Which first stage will be used for this launch?
(semi-rhetorical question)

Falcon 9 first stages are now apparently cleared for use up to twenty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

1064.6 and 1065.6 are the Falcon Heavy side boosters for Europa Clipper.  1072.1 and 1086.1 are assigned as the Falcon Heavy side boosters for GOES-U.

1073.15 and 1076.13 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are currently available for "single-stick" launches.

Available first stages, with UTC date of most recent recovery:
1077.12  Mar 10
1080.7    Mar 21
1060.20  Mar 24
1078.9    Mar 25
1076.13  Mar 30 (maybe)
1067.19  Mar 31 (maybe)

Edit April 16: It's B1077.12.

Here are two pairs of NGA Space Debris notices (each pair has the same notice for two different Navigational Areas). Neither one exactly matches this launch.

The NGA Rocket Launching notice is for April 17 to April 23, as are the S2 NOTAMs posted by Galactic Penguin SST.

One pair of the Space Debris notices is for April 16 to April 24; the other pair is for April 17 to April 26.

SpaceX is targeting Wednesday, April 17 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Liftoff is targeted for 5:26 p.m. ET, with backup opportunities available until 9:24 p.m. ET. If needed, additional opportunities are also available on Thursday, April 18 starting at 5:05 p.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 12th flight for the first stage booster supporting this mission, which previously launched Crew-5, GPS III Space Vehicle 06, Inmarsat I6-F2, CRS-28, Intelsat G-37, NG-20, and five Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

Landing and orbital insertion appear to have been successful.  Reloading feed shows current, but frozen, frame.

To be clear, I saw a landed booster and Stage 2 velocity static at 27,000±.  Sorry, didn't get screen cap.

Shows landed booster, but Stage 2 still short of orbital velocity, but seemed to be well on its way at the time of the capture.  EDIT.  If later update showed 27,000 km/hr, then seems good orbit.  My Hmmm wasn't at this thread, but at X for its failed SpaceX webcast.  Again.  It cut off at T+3:00 it seems.
EDIT 2:  SpaceX now confirms good initial orbit.  Second burn coming.

NSF had some great shots of ascent.

American Airlines flight 1914 from Dallas-Fort Worth just landed successfully at Norfolk International Airport.  Saw that on FlightAware.

No news coverage of that routine event.

Are we getting to the point that Starlink 6-51 is so routine that it is worthy of no live coverage?

(Rhetorical...and I'll show myself out.)

They appeared to be testing streaming where you could rewind or come back to live, just as with YouTube.  Looks like that new feature glitched.

Should have completed second burn and payload deployment by now.  I'm watching X, but no update just yet.

And now, from SpaceX moments ago (around 2248 UTC):  Payload deploy confirmed.

Perhaps this is part of the reason that the Launch Communications cut out????  There was none licensed?
Tomorrows flight of 6-52 also shows >>>Pending<<<<

This application uses information from previous application 0161-EX-ST-2024. This STA is necessary to authorize launch vehicle communications for Mission 1946 Starlink Group 6-51 from Cape Canaveral FL at LC-40 CCAFS or LC-39a at KSC, and the experimental recovery operation following the Falcon 9 launch. Includes sub-orbital first stage, and orbital second stage.

Can someone tell Tyler that he is still missing one US launch this year? 😊 Starship IFT-3 should also be included.

It's in the orbital section of Jonathan's space report and it achieved orbital velocity.  So that is well good enough for me.

Boy, the control system looks like it got saturated there for a minute a low altitude.  One fin went to full deflection and stayed there for a couple of seconds, plus the RCS got into the act to help out.  I'm guessing some low level winds needed to be countered.

If it was orbital, if it achieved orbital velocity at orbital altitude above the atmosphere, it wouldn't have reentered.   You would also be able to find it on Space Track with an International Designation, etc., but you can't.  Also, if it was an orbital attempt, it failed.

Unlike Starlink 6-51, which was a successful orbital launch!

Some reusability stats for this launch (Starlink Group 6-51):

Booster B1077.12 turnaround time:
37 days 22 hours 21 minutes
(its previous mission was Starlink Group 6-43 on Mar 10, 2024 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 43.90 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad LC-39A turnaround time:
9 days 22 hours 10 minutes
(the previous launch from this pad was Bandwagon-1 on Apr 7, 2024 UTC).

FYI: median turnaround time for LC-39A is currently 17.64 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet (https://docs.google.com/spreadsheets/d/1WwD3CzpKR6vNgYS3QlxoOK9WLi81fof9zRiXzGCnbwo/edit?usp=sharing) online.

Your OPINION is noted
JCM’s CALCULATION shows that the semimajor axis of IFT-3’s exceeded Rearth plus some margin like our favorite 100km, making it a successful orbital launch as designed.
To do otherwise is to call OFT-1 and -2, and the upcoming CFT and all Starliner launches orbital failures by design.

Yeah, it’s Tyler’s list and he can put what he wants in it, but my sincere suggestion is that we take this argument, and all the record keeping, launch, landing, and reuse, OUT of the launch specific threads and give it their own.  Some of those already exist and don’t need replicating elsewhere.

JCM wrote in his Space Report that the "orbit" achieved had a negative perigee:  -50 x 234 km x 26.5 deg. He also wrote that "[t]he Ship flight was not fully in orbit and so did not receive a US Space Force catalog number
or an international launch designation.

JRTI departs for Starlink 6-53!  - A super rapid turnaround.

Not certain what the record is for the time between delivering a F9 and departing for the next but 8 hrs and 15 mins must be close!
