The Falcon 9 first stage rocket booster supporting this mission previously supported launch of GPS III Space Vehicle 03, Turksat 5A, and four Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean.
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.

Starlink v1.0 L23 will likely be the final launch before SpaceX begins to focus on the Crew-2 mission, lifting off from LC-39A on April 22.
https://www.nasaspaceflight.com/2021/04/spacex-launch-starlink-l23/Quote Starlink v1.0 L23 will likely be the final launch before SpaceX begins to focus on the Crew-2 mission, lifting off from LC-39A on April 22.A 16 day gap between launches at SLC-40 seems unlikely to me, especially when SpaceX has scheduled launches with a 7 day turnaround.B1051 and B1063 should be ready to go. Maybe even B1060.
Why not B1049?

Sunrise is 6:49am. The launch time gets 22-26 min. earlier each day. Then, a Falcon 9 will launch the Starlink 24 internet satellite batch on TBD. Other upcoming Falcon 9s include more Starlink batches on TBD. A Falcon 9 from pad 40 will launch the SiriusXM-8 on June 1 at 12:25am EDT.

It is also possible that with the recent run of frequent launches that they simply don't have the next Starlinks (or upper stage or fairing) ready yet.
It is probably all hands on deck for Crew 2.
S0, will this launch fill out the initial 18 satellite minimum for all 72 53° planes in the 1st shell?

Just Read the Instructions droneship is being prepared to depart Port Canaveral later today for the next Starlink mission.Tug Hawk will tow JRTI ~633 km downrange to the landing zone.
Departure! Just Read the Instructions droneship is underway from Port Canaveral for the next Starlink mission!Live views from NSF Fleetcam: youtube.com/watch?v=gnt2wZ…
The droneship logo has been repainted on JRTI too!#Blessed
The SpaceX fleet is about to have a very busy week...- OCISLY w/ B1061-2 en-route to Florida (ETA Monday-ish)- JRTI en-route to the Starlink LZ- GO Searcher stationed for Atlantic Crew-1 splashdown in, Navigator in Gulf- GO Quest and Shelia Bordelon preparing for Starlink
Tug Finn Falgout has just departed Port Canaveral - amid reports via maritime radio - that tug Hawk, currently towing JRTI droneship to the Starlink LZ, has suffered a mechanical fault and needs rescue.Support ship GO Quest has also departed - which may linked to that effort.
Quick update on this: First thing this morning Just Read the Instructions was handed over from Tug Hawk to Tug Finn Falgout, with the help of support ship GO Quest.The fleet is now en-route to the Starlink LZ. I'm not convinced they'll make it in time for T-0 but we'll see...
SpaceX is targeting Wednesday, April 28 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 11:44 p.m. EDT, or 3:44 UTC on Thursday, April 29.The Falcon 9 first stage rocket booster supporting this mission previously supported launch of GPS III Space Vehicle 03, Turksat 5A, and four Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean.
I was close when I heard about the one-day slip.I assumed it would be 22 minutes earlier than the original launch time (04:05 UTC), so that would’ve put the launch time at 03:43 UTC.

Is it ok to comment in here?Something that I can't ever figure out about night launches: why can we see the RCS firing at night? It's cold nitrogen gas, isn't it? Yet, you could easily see thruster pulses when you couldn't see any of the rocket being illuminated. I've never understood this. Does the RCS produce visible light or is there something else going on here? I've noticed this on other nighttime launches as well. Sent from my Redmi Note 7 using Tapatalk
Falcon 9 Marks 4th Launch in Four Months With Midnight Starlink Mission
The #SpaceX #Falcon9 meets the Moon as another batch of #Starlink satellites are sent to orbit. Congrats to @elonmusk & team on another successful launch & landing!(📷: me / @WeReportSpace)
Beautiful launch this evening by SpaceX with their Falcon 9 rocket on their 25th #Starlink mission.We went "Exploring" tonight can't wait for the next one!Special huge thanks to @flightclubio 📷: me for @gospacelaunch
Shelia Bordelon is in the lead for L24 return with the fairings. (Will offload and head right back out) while GO Quest, Finn and JRTI are coming back with B1060-7.

Does anyone have a guess on when I can see the booster return? I’m in town and would love to see it come in.
Shelia Bordelon has returned to Port Canaveral with two fairing halves that she fished from the water from the last starlink launch. #SpaceXFleet #SpaceX
Shelia is docked now and you can't really even see the fairing halves anymore lol
Shelia Bordelon unloaded the recovered fairing halves from the Starlink L24 mission onto waiting transporters. They'll resupply and head back out for the L25 mission scheduled 5/4. GO Searcher saying peek-a-boo as they ready for their Dragon duties. #SpaceXFleet #Fleetcam
Incoming @SpaceXFleet!
Just Read The Instructions (JRTI) has entered Port Canaveral. Welcome home, Booster 1060.7. Great job!
Falcon 9 B1060-7 returning to Port Canaveral earlier this afternoon. I had a good time chatting it up with folks. It’s always great to see the increasing enthusiasm for spaceflight, and I enjoy sharing mine with others.🚀@SpaceX #Falcon9 #SpaceCoast @considercosmos
