https://www.nasaspaceflight.com/?s=Starlink (https://www.nasaspaceflight.com/?s=Starlink)
Successful launch August 7, 2020 at 1:12am EDT (05:12 UTC) on Falcon 9 (booster 1051.5) from LC-39A. ASDS landing on OCISLY was successful. The fairing catchers did not manage to catch the new payload fairing halves in flight. Targeting deployment orbit of approximately 380 x 400km altitude, 53 degree inclination.
Payload: 57 Starlink satellites plus rideshare satellites. BlackSky will have two of their earth observation satellites on the flight. Each BlackSky satellite is about 55kg.
Please use the Starlink Discussion Thread (https://forum.nasaspaceflight.com/index.php?topic=48297.0) for all general discussion on Starlink.
L2 SpaceX:
https://forum.nasaspaceflight.com/index.php?board=60.0 (https://forum.nasaspaceflight.com/index.php?board=60.0)
From a previous mission's Press Kit:
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 in the Northern U.S. and Canada in 2020, rapidly expanding to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

I'm not really sure where to post this since the entire question is what rocket this might be flying on, but there have been a couple recent filings for ground stations to support the early operations of two Blacksky sats NET June 22. Would that be the already known SSLV flight with just two sats instead of four, or a different launch altogether?
I guess now we have the answer.
[Space News: June 5, 2020] BlackSky launching two satellites on June Starlink mission (https://spacenews.com/blacksky-launching-two-satellites-on-june-starlink-mission/)
Earth-observation company BlackSky will launch two satellites as co-passengers on a SpaceX Starlink mission expected to occur June 24, Nick Merski, vice president of space operations for Spaceflight Industries, told SpaceNews.

And it turns out they want to do a pretty quick turnaround of 1051 for this mission. Around 63 days if the date holds and this is for the fifth flight!
Previous missions of this booster:
Crew Demo-1 in March 2019
RADARSAT Constellation Mission in June 2019
Starlink-4 (V1.0 L3) in January 2020

SFN launch schedule (https://spaceflightnow.com/launch-schedule/) now shows a launch date of June 22, 22:20 UTC. That means it was pulled forward by a day or two.

I can’t believe the pace they’re on. We waited and waited for a booster to get to a 5th flight, and now we’re getting the third 5th flight in only three months.

Cross-posts re: news progression of June 2020 Starlink/Falcon 9 launches utilizing both SLC-40 and LC-39A, narrowing down to this flight as the first Falcon launch from LC-39A after the DM2 Crew Dragon launch:
(SpaceX after DM-2)
Upcoming launches include: Falcon 9s will launch the eighth, ninth and tenth batches of Starlink satellites from pads 40 and 39A as early as June TBA. And a Falcon 9 is slated to launch the next GPS III satellite for the U.S. Air Force from pad 40 as early as June 30, likely in the middle of the night.
http://www.launchphotography.com/Delta_4_Atlas_5_Falcon_9_Launch_Viewing.html
http://www.launchphotography.com/Delta_4_Atlas_5_Falcon_9_Launch_Viewing.html
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the eighth batch of Starlink internet satellites from pad 40 on June 3 at about 9:25pm EDT. The launch time gets roughly 20-21 minutes earlier per day. Then, a Falcon 9 from pad 40 will launch the ninth batch of Starlink satellites on early June TBA. A Falcon 9 from pad 39A will launch the tenth Starlink batch on June TBA. And a Falcon 9 is slated to launch the next GPS III satellite for the U.S. Air Force from pad 40 as early as June 30, likely in the middle of the night.

Well this is still far from Elon's 24 hours turn around goal. Pace is faster since they are using two pads and two droneships. I don't know where did your concern come from.

Perhaps the static fire decision is related to where the booster last landed? For the L8 launch, the booster used (1059) landed at the cape on it’s previous CRS mission. The booster for this launch (1051) last landed at sea.
If the pattern holds from a sample size of one, then there will be a static fire.

Isn't this launch the one that's supposed to have sunshades on all the satellites?

Isn't this launch the one that's supposed to have sunshades on all the satellites?
If so, what do those sunshades weigh? 60 of them might add a good few tons to the payload mass. Do they reduce the number of satellites that can be launched, or are they lightweight enough not to make a difference?

Quite doubtful
They aren’t going to be made of cast iron.
Some treatment on composite, perhaps
A few kilos at most each, spring and latches included.
Times 60 will be under half a ton, possibly a fraction of that.

It’s made of a special dark foam that’s extremely radio transparent, so as not to affect the phased array antennas. Looks a lot like a car sun visor.

[zubenelgenubi: Article is dated May 27, 2020. There have been 2 Starlink launches, of 60+58 satellites, between the article date and the conclusion of the June 13 SpaceX launch coverage. The first VisorSat was aboard the June 4 UTC launch.]
Patricia Cooper, SpaceX’s vice president of satellite government relations, said May 26 that SpaceX has another 80 or so Starlink satellites it is preparing to launch based on their current design before regularly incorporating sunshades that block sunlight from hitting reflective parts of each satellite.

SpaceX has only missed out one static fire, so I don't think you can declare a trend just yet. I'd imagine they are more likely to become situation-dependent based on vehicle condition, customer requirements and other stuff I haven't thought of.

2 days from launch, seems that there won't be a Static Fire.
SpaceX needs to get comfortable launching without static fires for the future of SS anyway.
This is a great use of internal missions to push the reuse of boosters and fairings and now procedures.
It will be fun to see how much they can reduce the booster cycle time.
-

Why? We've seen them static firing much closer to launch than this before, specially for Starlink with fairing on top.

There they go! Ms. Tree and Ms. Chief have departed from Port Canaveral for the Starlink mission.
They will not attempt to catch the fairing this time but will recover it from the water.
https://twitter.com/spacexfleet/status/1275540729146859520
With two missions on deck for the #SpaceXFleet I thought I would take a peek in port. Sisters are still here most likely waiting out weather. Only the scoop nets are rigged so there may not be a catch attempt. Dunno know why. 🤷♀️ JRTI has a crew prepping on deck ahead of GPS III.
-
I believe the fairing catch attempts are mostly automated. So if they are reviewing and reprogramming the algorithms, they may hold off until they are ready to retest. They already know they can reuse fairings in the water, and have damaged them during failed catch attempts, so it may be prudent to hold off until they are more confident they can catch successfully.

https://space.skyrocket.de/doc_sdat/blacksky-global.htm
Given each BlackSky Global satellite is 56 kilograms, which means both total 112 kilograms, adding the 57 Starlink sats makes the total payload mass 14,932 kilograms.
-
Pure speculation, and wondering "what if?"
What if a part of the reason SpaceX is utilizing the new (for Starlink) higher deployment orbit of 388 x 401 km, and possibly a small bit of payload margin, is because they are iterating on a quicker-to-deorbit payload separation mechanism?
Deploying in that higher orbit, in the rough range of ISS orbital altitudes, seems a bit odd if they were going to just leave the deployment rods as space debris as on previous Starlink launches.

NOTMAR/NOTAM Launch Hazard Area map visualization of Starlink v1.0-L9 mission (https://www.google.com/maps/d/viewer?hl=en&mid=1IDaH4FjeWQAh4d2rDf8QD99A1ELP-W1W&ll=30.87834138971509%2C-78.21116190702423&z=7) from LC-39A for Jun 25 20:39 UTC, alternatively Jun 26 20:18 UTC.
Compare to previous Starlink launches there is slightly moved booster landing position for B1051.5 also with slightly longer Hazard Area B (orange one).
There is also an additional area of unclear purpose (green), similarly as it was during Starlink mission in April.
Stage2 deorbit during second orbit with debris reentry to the area across Indian Ocean this time, similar as first four Starlink launches where also was a circular deploying orbit.

Could this simply be that the rideshare customer wanted a higher orbit for their sats and Starlink could handle that orbit?

57 seems like odd. Has there been any previous confirmation of the number? All I can find are secondary sources that mention 58.

Yes, 57 was also mentioned by T.S. Kelso, an astronomer who runs CelesTrak and receives Starlink satellite trajectory data from SpaceX before each Starlink launch, it was posted upthread by gongora.

Any specific reason given for the delay? Just more rocket work needed?

I'm guessing they wanted to get the next flight's SF out of the way.

Y'all asked for it so here you go! B1051.5 at LC 39-A on the left and the recently static fired booster for GPS III on LC-40 to the far right. You can also see the MLP for OmegA, VAB and LC-41 where an Atlas will launch Perseverance in July. Busy Cape Range!

There's quite a lot going on at the Cape right now! Using @julia_bergeron's photo, I marked each point of interest in this shot.
Two Falcon 9s, One Atlas V going to Mars, parts of SLS, and OmegA! These next few months are going to be a lot of fun to watch.

On leaving the "rods" at such a high orbit...
I wonder (speculation hat on)
Have SpX added some sort of thruster package (using a StarLink sat buss) to each one with the intent they will deorbit themselves???
(speculation hat off)
I mean... the later planned launches to higher orbits almost mean they have to have something planned...
And I think, tethering the rods to the S2 to drag the whole mess down is risking punching a hole in the tank...
I will be watching... Very curious ???

According to Spaceflight Now, the precise launch time is 4:18:02 PM local (20:18:02 UTC).

It also looks like they are investigating a leak in Falcon 9.
According to a SpaceXer on r/SpaceX, teams are "investigating an O2 sensor showing a slight leak in the E9 engine bay. Slightly off nominal, but nothing too crazy." Could push Starlink closer to GPS. https://old.reddit.com/r/spacex/comments/hfy9rw/two_falcon_9s_vertical_lc39a_and_slc40/fw2ax1f/

Yes, would be the third "fifth" flight of a booster. Could be the second "fifth" recovered if recovered.

I split off the growing Static Fire/no Static Fire discussion into a new thread: SpaceX Falcon 9: To Static Fire or not to Static Fire; that is the question (https://forum.nasaspaceflight.com/index.php?topic=51340.0).
I moved the new thread to the SpaceX General Section sub-forum. It seems to me to be a question not for a single mission, but relating to SpaceX launch operations at large.
I suspect that this discussion will continue for some time.
-
https://twitter.com/nextspaceflight/status/1276709173284057089
And the flight restrictions for June 28 have also been removed. As originally expected, SpaceX will in fact wait until after the GPS mission to launch Starlink. Seems like a sensible plan.

Super hazy day in Florida! I’m a little surprised that #SpaceX has left the next #Starlink mission on the pad with it being delayed until after GPS.
Is it more efficient to leave the F9 + payload vertical on the pad? The Starlink launch may be shortly after the GPS launch.
(Or has SpaceX since rolled the LV back into the LC-39A HIF?)

Surprisingly, the LV is still vertical at the pad:
https://science.ksc.nasa.gov/shuttle/countdown/video/chan3large.jpg

There was some talk of an oxygen sensor in the engine bay having issues. Maybe it's easier to fix this particular problem in the vertical position for some reason?
-

It looks like they’re taking her horizontal now.
-
Could they just swap booster with another one while this one goes through checks and fixes?
-
Could they just swap booster with another one while this one goes through checks and fixes?
No. They have a limited number of boosters available, and the boosters with lower numbers of flights would be assigned for external customers (they have two of those flights that could happen in July). There may not be another booster available right now for Starlink. It would also probably take several days to swap boosters even if another was ready to go.
-
There was some talk of an oxygen sensor in the engine bay having issues. Maybe it's easier to fix this particular problem in the vertical position for some reason?

From Starlink v1.0 L7:
What happens to the booster that was on the pad, now that its set to launch in June? Do they take it down and bring it back to the barn?
Yes. F9 will be rolled back into the barn for weather protection of rocket and payload.
Payload stack (including fairing) will also be de-mated and stored in vertical (upright) position. A Starlink stack doesn't like being stored horizontally for prolonged periods of time (sagging of the stack is just one concern).
So if we're speculating why this F9 was vertical until now, another possibility is that they wanted to finish horizontal integration of GPS before lowering this rocket, so the Starlink stack did not have to remain horizontal while waiting for integration/deintegration equipment to be available.
Edit: Theory in next post makes more sense -- shared work crew rather than shared equipment. My modified speculation is they did not want to lower the Starlink F9 to horizontal until the people were ready to do the deintegration.
-
So if we're speculating why this F9 was vertical until now, another possibility is that they wanted to finish horizontal integration of GPS before lowering this rocket, so the Starlink stack did not have to remain horizontal while waiting for integration/de-integration equipment to be available.
Good thinking. Also, good finding the quote from a previous launch thread!
However, the GPS F9 is launching from SLC-40, and the Starlink F9 is launching from LC-39A.
I assume that each launch complex or Horizontal Integration Facility (HIF) at each complex has its own complete set of tools and equipment, so to speak. Is this a correct assumption? If so, that should not prevent full-on campaign work simultaneously at the two launch complexes.
Another assumption: the encapsulated payloads, removed from their launch vehicles, would stay at their respective HIFs. Therefore, no move of payloads back to their respective processing facilities.
Or, SpaceX chose to do as they did because it was better from a human-hours/labor costs consideration? Rather than working 2 full, separate crews at both launch sites simultaneously?
TL;DR IDK. Someone else here might.

No, it's not. They only do it if the launch is late enough in the day. Each forecast has a "Next Forecast Will Be Issued" section at the bottom and if they plan to release the L-0 forecast, it's noted in the L-1 forecast. This time it stated "As Required", which usually means no L-0 forecast.

Is there any indication as to why the scrub? They've waited until well after prop load to scrub for weather before. This sounds more like a problem with the booster or the payload.

This is my theory at this point, pretty useless to say “checkouts” is the reason when they’ve had countless days to do any checkout they need to do (not to mention counting to t-1 minute) so definitely something wrong with Rocket I think.

Hmm... this is the first Falcon 9 in a while that didn't pass its static fire with flying colors, had to be brought back into the barn and delayed for what was identified as a leaking valve. And the launch attempt scrubbed for weather was counted down to T-1 minute to get "data collection" on the booster, before being aborted. Now, today they won't even consider moving to prop load. What type of "additional checkout" could be needed? This booster has been static fired since its cleanup/refurb, and has been up and down on the pad several times. Seems, as has been said, that they've had tons of time to run checkouts.
This seems (note, I said "seems") to add up to there being something going in with this booster that is seriously concerning to those responsible for launching it. There seems to be more internal pressure *not* to launch than on any previous Falcon I can recall. Ever since the static fire, it just feels like SpaceX is spring-loaded not to launch position on this one, but to scrub position.
Again, hmm...

I've watched too many rocket launches and way more scrubs to be concerned at this point.
This is the 5th flight of the booster, so maybe they are learning the limits of some components. Standing down is great, shows maturity. They'll get this one off soon.
Edit: This was going to be part of my Saturday morning entertainment. Now what am I suppose to do :(

1048.5 also didn’t pass static fire with flying colors, then aborted due an engine issue, and finally lost due to an engine issue.

OCISLY and support ship GO Quest have both departed from the Starlink LZ.
GO Quest has turned in the direction of the ANASIS-II LZ and it looks like OCISLY might be returning to Port Canaveral.
The intentions of Ms. Tree and Ms. Chief are not immediately clear.
-
all providers are equal when it comes to the vagaries of weather. ;)
This seems off. The Shuttle, for example, could not launch in cold weather, but Russian rockets seem to have little problem with this. And ICBMs are explicitly designed to launch in bad weather, as waiting a few days for the weather to improve is not an option.

Moderator: Thread trim.
Sferrin, you had a post deleted, but you continued your sub-NSF-standard discussion re: the alleged failure of SpaceX to launch Falcon 9 on-time. And others responded.
Member: I give you a hypothesis to discuss in the following post.
-
The #Falcon9 for #ANASIS2 just went vertical on neighbouring SLC-40 for Static Fire later today!
Could the cancellation of the Starlink launch today (July 11), for an "internal" customer have (partially?) been to allow the Static Fire for the Anasis-II LV, also today, for an external customer?

Doubtful. Last week when there was an attempt, if it had gone to plan Starlink would have launched off 39A and the GPS III booster would have had its static fire at 40 later in the afternoon.

Clearly 5th flights are posing a challenge right now in the learning curve of the reuse of these boosters.
There's a bunch of juicy info on reuse in a recent talk / Q&A with Tom Mueller. It's been reported in a few places that the booster failure was due to leftover alcohol in a sensor deadleg from cleaning the engines. The fix was to simply not do it. I don't think this particular failure mode was unique to a deeply reused rocket - just happened to be on a fifth reflight. However, it is related. Mueller claims that they found making a conventionally designed engine reusable was often just a matter of adding bits of material in the right places (usually points of stress concentration) to improve cycle life. It doesn't take much to go from 1 to 10 flights, apparently, if you actually looked into it. The biggest problem he mentioned with reusing the Merlin 1Ds was that kerolox is very sooty, and they need to do a pretty thorough, intensive cleaning to maintain engine performance on subsequent flights. This is partly why he expected Raptor to be practically better for reuse and refurbishment - methalox is just a lot cleaner.
Perhaps now that they stopped doing this additional cleaning step, they started finding extra soot buildup causing issues with sensors on the reused engines. The original failure on B1048.5 was caused by solvent in a sensor deadleg, and an oxygen sensor was reported to have issues after this SF. Maybe it turns out there's just still soot stuck in that deadleg, and they need to take the whole stack down for a much more thorough cleaning of the engine.
Alternatively, I wonder if they made the cleaning process change *after* these engines were already cleaned, and they're worried there's still signs of residual solvent in some of the deadlegs.

The impression I got was that they simply needed to make sure they didn't leave the solvent in the lines. I don't think the comment implied they would skip the cleaning step.

Would they have counted down to T-1 minute during the weather scrub last week to test the payload?

Practicing abort procedures; safing, detanking, etc. And remember that scrub was for weather. We don't really know why the subsequent launch attempt was cancelled (at least I don't think so).
Have a good one,

Given Elon's reference to 'swap hardware if needed', does anyone think that there's a chance that L9 got delayed specifically because they already saw the problem with the ANASIS 2nd stage, and that the 2nd stage for L9 might fly on ANASIS?

Given Elon's reference to 'swap hardware if needed', does anyone think that there's a chance that L9 got delayed specifically because the already saw the problem with the ANASIS 2nd stage, and that the 2nd stage for L9 might fly on ANASIS?
No
While that was a fabulous Jim impersonation, might you elaborate why they would not do this if they felt the time to repair the ANASIS 2nd stage might be extensive?
Thanks.
Well, since more serious Block 5 reuse started, production of upper stages has obviously been decoupled from 1st stage production so my counter-question would be why do you think there aren't any other available S2s at hand to replace it with?
Personally, I'm more interested in knowing what broke on ANASIS-II S2. Eric Berger's mysterious haiku-sounding tweet almost implies it's the niobium nozzle extension again.

ANASIS-II launch delayed. (https://forum.nasaspaceflight.com/index.php?topic=48217.msg2106716#msg2106716)
Standing down from tomorrow’s launch of ANASIS-II to take a closer look at the second stage, swap hardware if needed. Will announce new target launch date once confirmed on the Range.
That's a launch delay for Falcon 9's at both LC-39A and SLC-40.

I would expect plenty 2nd stages through production, but not necessarily on-site. They had seemed to try to time their deliveries of 'new' parts as late as reasonable the last time I watched closely (which was admittedly a while ago)
SpaceX had also seemed to be doing very well in avoiding delays for mechanical issues, and then to have two delays, days apart would seem to me (IANARS), to be more likely related than not. Of course they could still be related in a way that doesn't borrow a whole 2nd stage.
In any case, it's not that I am convinced that this is what they are doing, just investigating reasonableness as to why they would or would not.
Personally, I'm more interested in knowing what broke on ANASIS-II S2. Eric Berger's mysterious haiku-sounding tweet almost implies it's the niobium nozzle extension again.
I took that as more of a joke than an implication.
BUT, at this stage in their history, if they were to snip a nozzle extension again, I would expect them to fly it on a Starlink flight, not a customer flight..

I've heard from a company person that the "lean production" philosophy of getting nothing before you needed it worked about as well as most people assumed it would, and they've gone to more stock and redundancy thinking in most things.
Schemes that require everything to go exactly as planned always seemed a little optimistic to me.

Precisely. We now think that we know that Static Fire for the SAOCOM 1B launch will occur 5 days before launch. (https://forum.nasaspaceflight.com/index.php?topic=47380.msg2108598#msg2108598)
Ben Cooper currently has the same launch listed for late July or early August. (http://www.launchphotography.com/Delta_4_Atlas_5_Falcon_9_Launch_Viewing.html)
My hypothesis: If either the Starlink et al. payloads or the SAOCOM 1B et al. payloads are ready, then SpaceX would proceed with the launch campaign for that one launch before the Atlas V mission on July 30. The other Falcon 9 launch would wait until afterwards.

Is a July 29th launch date realistic considering Perseverance will be sitting on the pad next door?
I would say yes because a falcon has launched from 40 with an atlas sitting next door, but with how big of a mission this is that atlas is carrying I honestly don’t know.

My guess is this, that SpaceX can prepare for the 29th and if Perseverance slips a day or more they can go. If it doesn't slip then SpaceX stands down for a few days until SLC41 is clear.
I don't imagine SpaceX wants to be even seen as getting in the way of an interplanetary launch. There is competition between launch providers, but I think all of us space fans can appreciate missions like Perseverance.

I think it depends on when roll out of the Atlas happens. I believe in the past once Atlas is at the pad Falcon static fires or launches wait.

Does the fact that Atlas is carrying a ‘nuclear’ payload have any impact, or is that irrelevant considering all the safety features built into that payload.

See the coordinates of the polygon describing the second stage re-entry zone in the NOTMAR quoted above (https://forum.nasaspaceflight.com/index.php?topic=51150.msg2110404#msg2110404). The polygon describes the southernmost section of a sinusoidal curve, which is how an orbit is projected onto the Earth's surface. Those latitudes of those coordinates approximately match the orbit inclination of Starlink satellites.
The second stage re-entry zone for SAOCOM 1B should run roughly north-south, as it's going to a polar orbit (more exactly, a sun-synchronous orbit).
(If someone could map the NOTAM, it would be appreciated!)
EDIT: See map here (https://forum.nasaspaceflight.com/index.php?topic=51150.msg2111050#msg2111050).

Apparently, it's all approved. (I would like to read an explicit confirmation of such.)
Falcon 9 can launch on July 29 with Atlas V/MMRTG-loaded Perseverance on its pad a few miles away. Atlas V will move from its VIF to the pad on July 28. (https://forum.nasaspaceflight.com/index.php?topic=41005.msg2110577#msg2110577)

They should have four boosters in August. Whether they can actually launch that many depends on payload and range availability. Haven't heard anything about SXM-7, don't know if it's been delivered or incurred COVID delays like most other payloads.

Could DM-2 landing operations possibly interfere with the launch if they need to use August 2nd?

The launch would be over 11 hours before splashdown, so I don't think it would be a problem.

Storm #9 is now officially a storm named Isaias and scheduled to hit the cape on Saturday, August 1, 2020.
Image NOAA
Take a closer look at the storm path timeline vs. the August 1 launch time: 3:21 am EDT.
At launch time on Saturday the 1st, Isaias is forecast to be in between the Friday 8 pm and Saturday 8 am time-marks. That location is west of Andros Island in the Bahamas. That is well to the southeast of Miami, FL.
I think that's too far away to affect either launch weather criteria and the drone ship landing weather criteria.
A delay to the Sunday, August 2 launch window--a different matter.
-
However, it could complicate the returning of the booster to the port.
-
@zubenelgenubi
I agree with you. Though two points of concern I see. First the storm sped up a bit the last days, which should on the one hand be better that it can't suck it that much more additional energy but it could cross the launch time. The second issue I can imagine is if it increases in strength like storm 8 in Texas which grew to a hurricane level 1 if there is enough time even if the launch "fits" before the storm if there is enough time to handle all necessary safing thereafter.
But if I remember correctly SpaceX already had a launch ?2? years ago squeezed in just before a storm. Let's hope for the best especially for the people underneath the storm the next days.
-
Look at the Tropical Storm force wind arrival time. Currently hitting the Cape at ~8PM Saturday.
Going to be a close thing.
With the Droneship and recovery, I don't thing SpaceX would risk losing the rocket....
But. What do I know... *shrugs*

This interpretation is better than some of those before it, but analysis of the graphs requires care
This graph says this prediction is ~30% probability of tropical storm force winds arriving at the Cape no earlier than ~2AM Sunday.

Confirmation of the launch delay from Ben Cooper
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the tenth batch of Starlink internet satellites on August TBA at about 12-1am EDT.

launch.

This flight is starting to feel cursed. Feels like this batch of birds is always a week away from joining the flock in orbit. Hope this is not a sign of things to come for future Starlink launches. They need to be accelerating cadence, not slowing down.

Not extrapolating anything. Just expressing hope that such delays don’t become more prevalent. Hopefully we see a flurry of Starlink launches over the course of the next month to get them back on schedule.

C'mon :)
Such delays - caused by tropical storms/hurricanes - they ARE prevalent (more or less) during the hurricane season.
also
Such delays - caused by new technology development (like in "nobody did this before - ever") - they ARE prevalent - indeed.
This flight is going to use B1051 which flied FOUR times before. They do not have much experience with so *heavily used* boosters (nobody has), so delays are inevitable.
Especially - in project where they do not have much deadline pressure.
Bottom line - IMHO, there is no curse, just combination of bad weather with new tech.

Amen. From someone who grew up watching them just trying to get a rocket - any rocket - to lift off the pad without blowing up, let alone actually reaching space, stuff like delays for weather are just so "oh well". F9 is going to fly. There is literally no such thing as a curse on a rocket. Come on.
-
It seems that spacex whether they like it or not does flurries of rocket launches. Basically with 2 pads and quick turn around on the pad they build up a bunch of boosters and 2nd stages and payloads and then launch very quickly. Then because of various delays goes through a dry spell.
Nothing wrong with that. In fact it might be better from the standpoint of pad personnel to have on and off times like this. Once you get into the rhythm, keep doing it. More efficient from a human perspective.

Dont forget that revenue launches (ie anything other than Starlink) probably have priority, while Starlink goes when the other payloads arent ready.

I think people are just annoyed that the Landing Bingo can only support one mission at a time, sequentially. The more flights get popped in front of the current active Bingo game, and the fewer Bingo games we can have.
It's all about the breads and circuses, man... ;)

I think they're safe. They went one for three last month. I'd guess they get two at best in August. I'd put a poll up but I don't imagine it would be very popular. :-\

Because clean room garb is so flattering ...
Here’s a sneak peek at some of the hardware I get to work with! Behind our team are two of the @blackskyinc Global optical satellites attached to the triangular payload plate adapter that will be lifted and installed to the top of a giant stack of 57 #starlink satellites!
Photo was taken in the @spacex Payload Processing Facility (PPF) at Cape Canaveral Air Force Station at the beginning of June.
Our mission, StarLink 9, is *finally* attempting launch again tonight (tomorrow morning) at 01:15 ET!
For scale: those large blue structures in the background are how the Payload Fairings are maneuvered when vertical.

(I was confused with the launch updates on here, but I did check that it is the discussion thread. Apologies if it's not.)
I know this lot are carrying sun-visors, but are they still going to visible now? (Or within the first 24 hours? I recall reading, somewhere on here I think tha the best time to attempt to catch the "train" was within the first 24 hours (after which they disperse away)
..and if they are, where would one track them? I'll check N2YO, but didn't know how fast it updates after launch; so I thought to ask if there's another site that specifically tracks Starlink. I know of starlinkradar.com, but same questions about immediacy of update..

They should be visible until they start to maintain a "shark-fin" orientation (more about it here: https://www.spacex.com/updates/starlink-update-04-28-2020/)

I haven't seen any word about fairing recovery. They said in the webcast that if they catch them, they will show it in the webcast, otherwise keep an eye on social media.
Makes me think that they were fairly confident that they may catch them today and prepared to show it live or semi-live just after catching them, but something happened and they didn't catch them.

#SpaceX Starlink-10 launched into a thick soup of humid sky tonight from LC-39A, with 2 rideshare sats for @SpaceflightInc's customer @BlackSky_Inc. Another Falcon landing too. On to the next....

I love that these launches are so routine now. Looking forward to this booster doing its sixth launch and landing.

Streak shot from SpaceX website

Starlink V1.0 L4 - L8 all inserted into their coast phase at around 216km altitude. L1 - L3 however inserted at around 168km. Starlink V1.0 L9 marks a return to the earlier insertion altitude, at a slightly higher velocity, but with only 57 Starlink satellites on board.
Why? The 60 L3 satellites were deployed at an altitude of 302km, close to a circular orbit. The 57 L9 satellites were deployed at about 400km, also roughly circular, because that is the required orbit for the BlackSky rideshare satellites. Achieving this orbit required a small reduction in overall payload to 57 Starlink satellites.
As per some of the earlier missions, the L9 S2 throttled back to about 94% throttle at the 450s mark. It also burnt longer than L3 to compensate, and shut down travelling some 25m/s faster.

It takes about 3 minutes after launch to pass the Kármán Line, the boundary to #space around 62 miles above us. That requires 1.7 million pounds of heart-pounding thrust coming from the nine Stage 1 engines that are pushing 1+ million pounds of #engineering through... (cont'd)

Are you sure the orbit is the reason for reduction to 57 Starlinks? The delta-V between 302 km circular and 400 km circular is about 56 m/s. Getting rid of 2 starlinks (at 260 kg each), then adding 2 BlackSky (55 kg each) should increase second stage performance by about this amount using the usual assumptions (total payload about 15.6t, ISP=348, burnout mass=5.5t, including residuals), plus another 5 m/s from the first stage. So if it's really for performance (and not say mechanical fit of the adapter, or slightly larger or heavier visor-sats compared to the L3 versions) then this is really on the performance edge of the F9 recoverable.
Perhaps the throttle back of S2 was for load limiting? It kept the peak load to 3.5 Gs, where a normal Starlink launch goes to 4 Gs.

I realized in the webcast this morning's Starlink flight means the last 2 launches from historic 39A were the Demo 2 booster (1st flight, left) and the Demo 1 booster (5th flight, right). In the 2+ months in-between, the Demo 2 booster has already flown again (ANASIS-II mission).

Are you sure the orbit is the reason for reduction to 57 Starlinks?
John Insprucker claimed that was the case in the launch webcast, at T+01:04:22 (or 1:21:14 into the Youtube webcast).
https://youtube.com/watch?v=KU6KogxG5BE&t=4874 (https://youtube.com/watch?v=KU6KogxG5BE&t=4874)
... typically when we're flying Starlink, we go into an elliptical orbit after one burn and then we separate the satellites, and their ion thrusters will lift them to the final orbit. But for the spaceflight customer with the BlackSky satellites we needed to get to a circular orbit, so they required two burns, the second which you saw just a little while ago, when we got to apogee. That circularized the orbit, but in order to do that, that took more propellant out of the vehicle, so you couldn't carry quite as much mass, so we traded off three of the Starlinks, so we're at 57 Starlinks on the stack.
(I hope I managed to transcribe that correctly.)
(EDIT: Link to webcast, and spelling; thanks, kdhilliard.)

No, getting rid of 2 starlinks. I was finding an estimated performance for two fewer satellites, to show that according to my crude estimates, they could have fitted 58 Starlinks. So I was speculating that there was some reason other than mass. However, John Insprucker, later in the recent webcast, says that mass was indeed the reason. He should know, so my speculation is wrong.

I freaking love that SpaceX is able to put so much payload into LEO and only expend the upper stage!

Aha - I see what I missed. The above calculation estimates that the F9 could have inserted into the higher orbit with 58 satellites. I think this is correct. But SpaceX also needed to de-orbit the second stage from the higher orbit as well. It's not much (about an extra 30 m/s is needed, and the stage is 4 times lighter after the payload is separated), but it's enough to require three Starlinks less, not two.
