Thread for the Starlink 4-37 group launch.

NSF Threads for Starlink 4-37: Discussion

Launch December 17, 2022, 21:32 UTC (4:32 pm EST), from KSC LC-39A, on booster 1058-15.  The first stage is expected to land aboard Just Read The Instructions.

Payload 54 Starlink satellites to 53.2 degree inclination on a northeastern trajectory.  Initial orbit of approximately 230 x 335 km?

Starlink v1.5 satellite mass is now about 300kg after the addition of laser ISL terminals.

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

That would imply USSF 44 not until ~Oct 27th at earliest as both ASDS needed. That is quite possible I suppose, but if USSF 44 is earlier it would have to be before 4-37 which would push 4-37 later. If USSF 44 much later than Oct 27th then it might make sense to fit in a launch from 39A, maybe 4-37 or Eutelsat Hotbird 13F?

I edited my original post to clarify my thoughts.

Yes, availability of both ASDS for USSF-44 will constrain launches.

And (a guess), if the USSF-44 launch is delayed, then we will likely see Starlink Group 4 launch or launches scheduled at LC-39A so launch cadence may be sustained.

The foreign-manufactured satellites seem to launch from SLC-40.  There's a reason for that, but I don't remember it?

[crandles57]

I think I recall that at one time it was more difficult for foreign people or people employed by foreign companies to gain access to one or other of the launch sites. That might be necessary for integration work. Not sure if this is still the reason.

Typically FCC certifications can be expected to be posted 4-8 weeks prior to the Operation Start Date.  In the later half of that range for a non-standard mission like a Falcon Heavy.  Having not seen one yet for USSF-44, the chances of an October launch are looking unlikely

Perhaps that 'A' does suggest just one launch presumably 4-36 and not 4-37 in the timeframe to Nov 5. I could be reading too much into that wording - there is just about enough time for 4-37 in the period from Oct 26 to Oct 29 but that doesn't leave much room for delays.

B1058 will be the first booster to fly for a 15th time. Although I’m not sure if it’ll be temporarily taken out of service for a bit after landing, or if it’ll immediately begin preps for a 16th go.

It likely will undergo a more intense examination than usual, before starting to be refurbished. That would likely mean it would be out of the rotation for a while.

My instinct from some tweet I recall to the effect of -- "No obvious limit on reuse" ... is that they'll just keep processing and look for signs in the ordinary course of refurb.

Will this be the last Group 4 launch until replacements start going up?

There's still a few more Group 4 launches left, I think this might actually be the replacement batch already since there's still like 4-5 more "holes" in the list of Group 4 launches (example is Starlink Group 4-24). As far as actual true replacements go, I'm sure the mini Starlink v2s are gonna be that replacement

1583 is the total number launched.  That includes satellites that have deorbit for one reason or another.  1518 are currently in orbit. So one and a half launches are still needed.

Will Starlink 4-37 still be the SLC-40 launch immediately following HAKUTO-R?  If so, it would be an early December launch.

Edit November 30 UTC :  True, even with HAKUTO-R delayed from November 30 to December 1.

Spaceflight Now shows the launch on Dec 5 at ~9 pm EST (updated on Nov 29).

Ben Cooper has Dec 6 in the evening EST (updated on Nov 30).

Considering the HAKUTO-R delay, Dec 6 EST / Dec 7 UTC is probably the earliest possible date anyway.

OneWeb L15 and Starlink 4-37 will be launching almost three hours apart from each other. I think that's a new record for the shortest gap between two Falcon 9 launches.

[zubenelgenubi]

Will the Starlink 4-37 launch move forward to launch as soon as possible; or be the next SLC-40 launch on December 7 UTC; or will it retain its place in line at SLC-40 after HAKUTO-R?

The third choice would delay the launch of Starlink 4-37.

After further inspections of the launch vehicle and data review, we're standing down from tomorrow's launch of @ispace_inc's HAKUTO-R Mission 1; a new target launch date will be shared once confirmed. [Dec 1 UTC]

Edit December 1: So far, no changes to the SLC-40 launch order or timing.

Edit Dec 3: Choice #3.  Starlink 4-37 delayed; HAKUTO-R scheduled to launch Dec 7 instead.

Might this launch move to LC-39A in mid December, before the January launch campaigns begin?

Ben Cooper's site still says this is launching from SLC-40. But interestingly, it also says Transporter-6 is still planned for a mid-December launch without specifying the pad, so maybe T-6 is going to launch from LC-39A?

A Falcon 9 from pad 40 will launch a batch of Starlink satellites on December TBD around 7-8 p.m. EST. A Falcon 9 will launch a pair of internet satellites for SES on December 13, in the afternoon EDT.

I should have received a standalone Operations Completed cancellation notice from the NGA for HAKUTO-R.  Instead, I received this cancel-and-replace NGA notice that cancels the HAKUTO-R notice and replaces it with this information for what appears to be a Starlink launch.  But not on December 17.  The primary day is December 16, at almost the same time as O3b mPOWER 1-2.

<snip>

Might SpaceX be hedging their bets by setting up notice for a December 16 Starlink launch if something between the 11th and (perhaps) the 15th delays the mPower launch?

If the mPower launch is not delayed, then this Starlink launch proceeds on the 17th.

(Also noting there are 3 Falcon 9 launches scheduled 15th-16th-17th.)

i remember 25 minutes apart by soyuz U in 1969 so pretty close

Falcon 9, December 16 @ 4:21-5:49 p.m. EST (pad 40) and Falcon 9, December 16 @ 4:54-5:13 p.m. EST (pad 39A)

Also:

If both launches take place, it will beat the 1966 Cape Canaveral orbital launch record of ~99-103 minutes apart set by Geminis 8, 10, 11 & 12 and their Agena docking targets for closest back-to-back launches.

SpaceX is targeting Saturday, December 17 for a Falcon 9 launch of 54 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida. The instantaneous launch window is at 4:32 p.m. ET (21:32 UTC).

The first stage booster supporting this mission previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, Transporter-3, and nine 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.

New @SpaceX flight leader B1058 still on the dock at Port Canaveral for Day Three. It sure is the sootiest booster I recall seeing! That is the accumulated residue of 15 trips to space and back - More than any other “thing” (that we know of), other than Discovery. 👍🏻🚀

Discovery has 39 ups and downs, but Columbia had 28 ups, 27 downs, Endeavor had 25 ups and downs, Atlantis 33. So only has Challenger beat so far.
