Discussion thread for the Starlink 4-3 launch.

NSF Threads for Starlink: Discussion

Successful launch on December 2 at 6:12 pm EST (23:12 UTC) from SLC-40 with booster 1060-9. Successful ASDS first stage landing on ASOG. Fairing recovery is expected from the water.

Quote
SpaceX is targeting Thursday, December 2 for a Falcon 9 launch of 48 Starlink satellites and two BlackSky spacecraft [Global-12 and Global-13] to orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 6:12 p.m. EST, or 23:12 UTC.

The Falcon 9 first stage booster supporting this mission previously launched GPS III-3, Turksat 5A, Transporter-2, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.

Expected deployment orbit of approximately 430km at 53.2 degree inclination.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

From a previous mission's Press Kit:
Quote
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.

B1062 could be for this mission instead
Booster B1062.4 has been spotted recently at KSC with a second stage already attached, but since it wasn't used for Starlink 4-1, I'm guessing it will launch IXPE?

(We = the spaceflight community not privy to confidential information)

"We" know the next Starlink batch launch from Florida will be soon.  What we don't know are the planned particulars of that mission.

Launch Photography has mentioned this launch as TBA for some time; Next Spaceflight has listed NET November December for some time as well.

Edit Nov 15: If no Static Fire is needed, then the first we would know that the launch is imminent could be NOTAM publication and/or Falcon 9 transport to the pad about 1 day before launch.

Cross-posts from the manifest discussion thread:
SpX-23          LC-39A     August 29 (UTC)
Inspiration4  LC-39A    September 16
Crew-3           LC-39A    November 11
Starlink 4-1   SLC-40     November 13 12
??                   ??              ??
IXPE               LC-39A    December 9
Turksat 5B    SLC-40     mid Dec late 2021
SpX-24           LC-39A    December 21
CSG-2            SLC-40    December 14

An observation: If SpaceX wishes to, there is room in the launch schedule for another Starlink cluster launch from SLC-40 in late November [or early December, or late December], before Turksat 5B CSG-2

[Time for a SLC-40 launch campaign that does not conflict with CSG-2, as the CSG-2 launch from SLC-40 must also be accommodated.]

I don't know how much time the IXPE launch campaign needs, or I might also speculate about a launch from LC-39A in late November.

Edits: Nov 12 and 14

Congratulations SpaceX on what appears to be a flawless flight and a return of east coast Starlink flights. 

The rest of the 2021 Manifest looks like it could finish strong. Hopefully there can be 1 or two more Starlink flights before 12/31

<snip> Been meaning to do this for awhile but per Elon's tweet that SpaceX plans to launch 80t in Q4, that will definitely require at least a few more Starlink launches. Based on him saying that SpaceX launched 41t in Q3, I'll ballpark that as 13t for Inspiration4, 14t for CRS-23, and 14t for Starlink 2-1.

In Q4, we have two launches behind us and five more confirmed missions on the manifest:
Quote
Crew-3 (13t)
Starlink 4-1 (15t)
DART (0.7t)
IXPE (0.4t)
CSG-2 (2.2t)
Turksat 5B (4.5t)
CRS-24 (14t)
Altogether, that's about 50t, leaving room for two more Starlink launches to reach Elon's 80t prediction. I'd personally guess that that means one more Starlink launch from each coast before the end of the year.

SFN, SpaceX launch starts deployment of new Starlink orbital shell, November 13
Quote
At least four Falcon 9 missions are scheduled in December from Florida’s Space Coast, launching more Starlink satellites, NASA’s IXPE X-ray astronomy telescope, the Turksat 5B communications payload, and another NASA cargo mission to the space station.
Stephen Clark forgot CSG-2 (unless he knows something that he did not mention in his article).

See the CSG-2 launch thread regarding this:

I'm hoping this mission is called Starlink 4-2, otherwise I'll just throw myself off a cliff...

I'd also accept Starlink 3-1 if this goes to 97.6°.

Next Spaceflight has one NET November. (It gives it the name 2-2 but I think/hope that is just a leftover and likely to be wrong.)

There seem 3 4 possibilities for the 2 starlink flights:
VSFB Mid Dec or later
SLC-40 late Nov
LC39A late Nov
CSG-2 further delayed and replaced by Starlink flight
so at least one of them has to be late Nov if they are going to fit in 2 Starlink flights.

Quote
At least four Falcon 9 missions are scheduled in December from Florida’s Space Coast, launching more Starlink satellites, ...
does seem to suggest first and last options?
alternately perhaps the order of listed launches suggests SLC-40 late Nov window stretches into early Dec.

If this launch is going to be called 2-2 and will be launching to 70° it will make sense. It would just confirm that the first number is the shell number.

Does it make sense? If launching to shell 2 from both coasts that seems to suggest they want to fill shell 2 as fast as possible which would seem reasonable, but in that case, why do a group 4? (Perhaps they wanted to confirm they could do a launch of 53 sat to lower inclination?)

Have we seen FCC filings for 70° launches from Florida? I thought we've only seen 53.2° and 97.6°.

They filed for 6 missions from 40/39A with the Droneship placed at 23 17 50 N 78 58 45 W which would be fine for both polar and 70° launches. I think they would prefer to launch the polar satellites from Vandenberg to avoid the dogleg maneuver, but this wasn't confirmed anywhere. Those 6 licenses expire in Jan 2022 by the way

"We" are not "guessing" a booster identity.

There is insufficient public information to deduce identity.

B1062.4 was observed on November 4 being transported on the grounds, as reported up-thread, circumstantial evidence that it would be used soon.

If SpaceX chooses not to conduct a Static Fire, then we may not know the booster identity until:
1) SpaceX announces it;

2) A reliable someone with a reliable source announces it;

3) Our wonderful photographers provide enough hi-res photography to identify a booster by "soot-ological" and/or markings analysis;

4) Or one of our photographers snaps a hi-res photo with the tail number.

Edit/add: We may not know booster identity until November 30 or December 1.

(The word guess can have a negative connotation in English, implying a lack of thoughtfulness in reaching a conclusion.)
