The Falcon 9 first stage rocket booster supporting this mission previously supported launch of NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and two Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously supported launch of AMOS-17 and two Starlink missions, and the other previously supported a Starlink mission.
Each Starlink satellite weights approximately 260 kg and features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of Falcon 9’s launch capabilities. With four powerful phased array and two parabolic antennas on each satellite ... At end of their life cycle, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event their propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes. Further, Starlink components are designed for full demisability.Starlink is targeting service to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

It might be better to discuss booster assignments in the manifest discussion thread rather than spreading the conversation over multiple mission threads.
SpaceX has at least two more Starlink missions scheduled for launch before the end of March, and possibly more.
I would say that we're waiting to hear if this launch will be conducted from LC-39A in the near future, before Crew-2 launch preparations "take custody" of the launch complex.Or, if this launch will take place from SLC-40 after the Flight 22 launch (currently March 24) from same, followed by a pad recycle.I am also interested to learn what mission B1063 will be assigned to.

SpaceX is targeting Wednesday, April 7 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 12:34 p.m. EDT, or 16:34 UTC, and a backup opportunity is available on Thursday, April 8 at 12:12 p.m. EDT, or 16:12 UTC.The Falcon 9 first stage rocket booster supporting this mission previously supported launch of NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and two Starlink missions.

I don’t get the difference between the second and third stat above. How is “re-flight of a booster” different than “flight with a flight-proven booster.”
Quote from: Herb Schaltegger on 04/07/2021 02:55 amI don’t get the difference between the second and third stat above. How is “re-flight of a booster” different than “flight with a flight-proven booster.”Pretty sure this was asked and answered somewhere before (most likely on L22 ), something to do with FH boosters counting as reflight of a booster but not counting as a F9 flightsEdit: link to explanation in the L22 thread https://forum.nasaspaceflight.com/index.php?topic=53068.msg2209914#msg2209914 (see a few additional posts there on the subject)
Today's Starlink mission will utilize a booster making its seventh flight and two flight proven fairing halves.Lee Kanayama (@Falcon_1e) previews:https://www.nasaspaceflight.com/2021/04/spacex-launch-starlink-l23/
Quote from: Herb Schaltegger on 04/07/2021 02:55 amI don’t get the difference between the second and third stat above. How is “re-flight of a booster” different than “flight with a flight-proven booster.”The word 'booster' is the source of confusion. Too many people say booster meaning first stage. A booster is a helper, such as a SRB, so a F9 has no booster and a FH has two.
Good morning from Kennedy Space Center, where we can see a SpaceX Falcon 9 rocket on the pad at nearby Launch Complex 40. Liftoff of 24th Starlink set for 1234 ET.Slight return to normalcy here. MLP rolling around, parking lots fuller than usual, KSCVC tour buses out and about.
T-30 minutes until launch of Starlink; Falcon 9 and weather are looking good for flight. Webcast will go live ~15 minutes before liftoff → spacex.com/launches
Shelia Bordelon received her first shoutout on the launch webcast, note carefully wording as a "contracted recovery vessel"Further backing my speculation that Shelia is not the permanent recovery ship going forward.
and boy was the video good when it came backmaybe they trying something new
Quote from: cpushack on 04/07/2021 04:43 pmand boy was the video good when it came backmaybe they trying something newI suspect the loss of video was an issue on the receiving end since both stage feeds came back at once.
No video from either stage... seems a bit odd.

I also wonder if the support ships had tracking and were relaying it through starlink, based on getting video all the way down to the deck of OCISLY.
Too many people were trying to intercept SpaceX telemetry (and publish it on the twitters)Probably led to the issues with camera viewshttps://twitter.com/r2x0t/status/1379843322152431622Now these same people want to try to decrypt it

Otherwise you’re claiming SpaceX can’t decrypt their own video feed. Bear in mind that serious video feed encryption is literally consumer-grade technology at this point.
I've done written too much software to discount it. Adding an extra feature, which "should" work, but is low priority and isn't tested "live" until the rocket is in the air
SpaceX Falcon 9 B1058-7 lands on OCISLY.Great onboard view for this one!...
Chris G said on the stream at 25:30 for this launch that you can't launch Starship to a polar orbit for Starlink launches. I'm pretty sure that's false. Boca Chica juts out a decent amount into the Gulf of Mexico and the coastline south of that location is almost due south so a dogleg wouldn't even be needed much. Starship should be able to launch polar starlink launches from that location without issue.

Starship should be able to launch polar starlink launches from that location without issue.I doubt it. The extended overflight over Mexico would be a much risker than a narrow Cuba and Panama flyover. Perhaps when Starship flights are well established, but that might be a while. But this not the topic for this discussion I think.
The S2 view appeared at T+7:07, and the S1/S2 split screen at T+07:23, but the Booster camera was visible on the Mission Control screen seen behind Youmei Zhou (Dragon Propulsion Engineer and today's launch co-host) when they cut to her at T+06:33, with the Entry Burn Startup visible 10 seconds later, though they cut away from her at T+06:56 before the burn was complete.It might have been just a production issue, with the onboard camera feeds not initially available to the webcast video engineer.
Here is a comparison of the public booster telemetry from Starlink L22 and L23.Unlike recent missions, the L23 booster appears to maintain a high AoA all the way to MECO (normally the rocket pitches down just before MECO). As a result, the ballistic coast has an apogee about 10km higher at 126km, and consequently the booster lands some 18km further downrange at 633km.

Thanks for the feedback. I used to post them as .png files, but a couple of months ago there were some display issues with .png on the site, so I swapped to .jpg. Perhaps a mod can tell me the preferred site format?
Shelia Bordelon is now under one hour away from Port Canaveral with the fairing from the Starlink mission earlier this week.
SpaceX's new recovery ship the Shelia Bordelon arrived back in port early this morning with only 1 fairing from the recent Starlink 23 mission. The fairing appeared in good shape but the disposition of the 2nd fairing is unknown. #spaceX #NASA #Science #SpaceXFleet
OCISLY droneship and B1058-7 still closing in on Port Canaveral.Droneship should be within the vicinity of Port Canaveral around midnight, setting up an arrival after dawn tomorrow morning.
Good Morning ☀OCISLY and B1058 are just offshore and preparing to arrive at Port Canaveral in the next couple of hours
Falcon 9 B1058-7 has arrived at Port Canaveral.Watch live: youtube.com/watch?v=gnt2wZ…
SpaceX's Booster B1058.7 & OCISLY arrived at Port Canaveral just after sunrise this morning from this weeks #spaceX Starlink 23 mission The booster is getting extremely sooty with the NASA worm barely visible anymore but appears in good shape #NASA #Science @elonmusk #spacexfleet
Possibly the most famous of all the Falcon 9 boosters, B1058 has returned from her 7th mission. This booster began its life returning human spaceflight to the Space Coast last May during the DM-2 mission. These days, she passes the time sending Starlink satellites to orbit.
Worm vs meatball? Why not both?!
Thats odd. They just set 1058 on the ground instead of the stand they use to raise the legs.
Its over the stand now, guess they just set it down for some reason.
#SpaceX #Falcon9 #booster B1058 returns after its 7th flight. #spacexfleet
Holy levitating Falcon, Batman!B1058 is moments away from being placed on the transporter to be rolled away and prepped for another mission. But if you’re watching Fleetcam, you already knew that. youtu.be/gnt2wZBg89g
B1058 spent the majority of the morning working on its legs. Now that they've all been retracted, we're just waiting on the second crane to attach and lay the booster on its side. Another beautiful day at the port.
