NSF Threads for Starlink v1.0 Flight 11: Discussion (https://forum.nasaspaceflight.com/index.php?topic=51758.0) / Updates (https://forum.nasaspaceflight.com/index.php?topic=51758.0)
Successful launch September 3, 2020 at 8:46:14 am EDT (12:46 UTC) on Falcon 9 (booster 1060.2) from LC-39A. ASDS landing on OCISLY was successful. Fairings were not recovered intact. Deployment orbit of approximately 212x346km, 53.0 degrees.
Payload: A batch of 60 Starlink satellites.
Please use the Starlink Discussion Thread (https://forum.nasaspaceflight.com/index.php?topic=48297.0) for all general discussion on Starlink.

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 also wanted to point out that the launch complex for this flight has not yet been announced--could be either at Kennedy LC-39A or Canaveral SLC-40.
How the Eastern Range in September looks now. I include MARS (Wallops) launches because, I believe, they share some range tracking assets with KSC/CC. Seeking clarification or correction.:

A Falcon 9 is scheduled to launch the eleventh batch of Starlink internet satellites from pad 39A on late August TBA. Other upcoming launches include more batches of Starlink satellites on September TBA.
Use of LC-39A would apparently be mandated because there would not be enough time to turn around SLC-40 before the end of the month.
I wonder how close the Starlink launch will follow after SAOCOM-1B.
EDIT August 21: Thinking further, Falcon 9 no longer needs range radar to determine if a flight deviation has reached the limits of triggering the destruct package--it's autonomous via GPS use. Therefore, there's no need to await a range reset of such between launches.
This launch could be as soon as August 28! That depends on the two previous launches being on-time and successful.
Three launches in three days?!

It would take at least 20 hours for Ms Tree & Ms Chief to travel from the SAOCOM 1B recovery zone to the Starlink recovery zone. With this Starlink launch pushing back one day, and over 38 hours between launches, it's quite possible that they can recover both fairings.
There might not be enough time to stop in to port and unload between launches, but that's probably OK. They recently demonstrated scooping a fairing half out of the water while a second half was already on deck. It may even be possible for them to re-rig the nets while underway following the first recovery, in order to make a second catch attempt. We'll see soon enough!

The other strategy I've heard suggested would be send one fairing catcher to each zone, try to catch one half, and just fish out the other afterwards.

Good way to lose a fairing because you don't know where it went and it breaks up by the time you find it. Based on the fact that we're hearing a possible 24 hour slip, they're likely gonna do it the proper way

Yeah...If they don't know where the fairing was going, it's not too likely they'd be able to put a ship there to catch it.

NROL-44 delayed to August 28:
Scrub!
twitter.com/ulalaunch/status/1298853251648040961
"Launch Director Lou Mangieri has announced that we will not continue with the #DeltaIVHeavy rocket countdown operations today for #NROL44. Another launch attempt will be possible in 24 hours."
SAOCOM-1B would be delayed to August 30, same time of day:
[Re: launch on August 28] Any idea why there is no longer a backup window on the forecast? Starlink-L11 taking priority?
If SAOCOM is delayed again, we'll have to wait a couple more days for a launch window. The 29th doesn't have the optimal conditions for orbit insertion.
If this Starlink launch must follow the SAOCOM launch by 2 days, that would place this launch on September 1.
If the launch time continues to regress by 21 or 22 minutes per day, then launch time on the 1st would be circa 1325 UTC.

1 for 3 in July. 1 for 3 - 4 in August. I get it, stuff happens. If SpaceX ever wants to get a full constellation up though maybe they want to start looking for ways to be less affected by external factors. They're building up quite a log jam. I wonder if they could add a launch site for Falcon 9 to Boca Chica?

Falcon is not launching from Boca Chica. Not all of the delays have been external factors. They've had launch vehicle and payload issues delay launches too. The blockade on SAOCOM launching while that really expensive payload is sitting on the pad next door is unfortunate, but that's partly from trying a new launch corridor, and only happened this time because COVID-19 delayed the first SAOCOM launch campaign. The Delta pad isn't used that often anymore. If NROL-44 gets delayed again they should be able to launch the Starlink mission from 39A before SAOCOM.

I'm wondering about how many Starlinks are piling up on the ground.
I think once we get through the summer weather that SpaceX can manage a 10 or even 7 day launch pace with 2 ASDS.
It's worth asking if SpaceX can manage flying and adding 60 new satellites every week. I suspect they have planned that into the project from the beginning.
I'm really enjoying these launches and look forward to seeing the Starlink beta start up soon.

There are two more Starlink flights scheduled for September, so it could be a rapid cadence for the next few weeks.

While GO Ms. Tree continues to the #Starlink LZ, it appears GO Ms. Chief may have stayed at the southern #SAOCOM1B landing zone after all. Last ping was almost 23:00 ET last night, well after Mystery left. A double header recovery weekend is looking promising.

We may need to just check back in a couple hours on the TFRs and see what's there. Right now I see ones covering the launch windows for NROL-44, SAOCOM-1B, and Starlink-11 on the 30th, but the Starlink window only has one of the two entries, then there are ones on Sept. 1 and Sept. 2 for something. Looks like some entries for ZJX still need to be posted. (Also looks like Astra slipped a bit over in Kodiak)
-
It looks like there is TFR for this launch on Aug 30, Sep 1, Sep 2, Sep 3. There is also a TFR for SAOCOM launch on the 30th, and SAOCOM has NOTMAR for each day Aug 30 - Sep 2. The weather forecast for SAOCOM on the 30th is only 40% Go. Could be a few days of watching to see what launches.
-
So the L-2 weather forecast for this mission is up. At the same time the SAOCOM forecast is still on the website, which would mean two SpaceX launches in a bit over 9 hours.
50% GO for the primary date, 70% GO for the backup date (48-hour delay).

Will need the Range and SpaceX to confirm, but the Starlink mission will likely be the next launch from the Cape. Still should be possible on Sunday morning, as the Delta IV Heavy delay will likely be several days.
Edit to add: now ULA have announced a minimum 1 week delay to their launch, hopefully means range is now available for SpaceX.

Even with the delay, I believe this is going to be the shortest time between two SpaceX orbital launches (38 hours and 11 minutes). If I'm not missing anything, the current record was set by the SSO-A mission and the CRS-16 mission (47 hours and 48 minutes).

The L-1 weather forecast is up. The probability of acceptable conditions for the primary day has improved to 80%, it's still 80% in case of a 24-hour delay.

Here is the Starlink V1.0 L11 telemetry. The L10 telemetry had a glitch at the end of the S2 burn, so I'm comparing with L7 instead.
There are a few differences:
1. The L11 throttle bucket is slightly earlier than previous missions.
2. Although an S2 throttle down was announced at T+08:00 on the mission webcast, there is no evidence of it in the data.
3. Both launches inserted at 215km altitude, but L11 was travelling 6m/s slower, at 7535m/s. Presumably the apogee will be slightly less.

I was looking at the fantastic data plots provided by OneSpeed and had a question for the rocket scientists in the forum. This may have been discussed at another forum. If so, I apologize in advance. My question is: As I recall, during the manned Dragon II launch Bob and Doug mentioned that the second stage ride seemed much rougher than first stage. The acceleration data in OneSpeed's chart seem to show a gradual increase in "noise" starting about halfway through the second stage burn. The noise, or vibration, gets progressively worse toward the end of the burn and the data from the latest launch (L11) even shows signs of periodic acceleration spikes. Does this relate to the "rough ride" noted by the astronauts?

That's quite possible. Small fluctuations in thrust will product small fluctuations in acceleration. As the fuel is consumed, the mass of the vehicle decreases and the amplitude of the acceleration fluctuations increases.

That's quite possible. Small fluctuations in thrust will product small fluctuations in acceleration. As the fuel is consumed, the mass of the vehicle decreases and the amplitude of the acceleration fluctuations increases.
That being said, I would not read too much into the noise in these plots. We do not have the raw telemetry, only the video stream, which displays altitude above ground and velocity in the rotating earth reference frame in km/h at the frame rate of the video, which is being processed by on-screen OCR to read out these values.
At this point this data is already preprocessed with some filtering by SpaceX, then rounded in the velocity domain to km/h and in the time domain to 1/30s Sometimes there's gaps in the data or small jitter due to transmission delays and buffering effects on the SpaceX media side.
However, the acceleration is the derivative of velocity so the change in speed per time. Due to the rounding to full km/h this is inherently noisy, and the jitter adds additional noise, which also increases the faster the rocket accelerates.
So - although you would expect the actual noise in the acceleration to also increase as the rocket gets lighter and as such small thrust fluctuations have larger impact, I would expect this noise to be at higher frequencies than the 1/30 s resolution we can see in the stream. The noise in these plots is most likely dominated by the noise introduced by the way this is read out.
A hint at the actual noise is given by the Falcon9 payload user guide (current version: https://www.spacex.com/media/falcon_users_guide_042020.pdf ) which lists the maximum axial acceleration noise under 30 Hz at 0.8 g and the maximum axial acceleration noise at frequencies above 100Hz at 0.9g - with a noise maximum at around 160Hz

this time it looked to me that the two bottom starlinks got tangled with each other and may have even bumped with each other. Does anybody see the same thing _ the left sat got almost at right angles with the stack rotating around the lower corner

Not a problem. They will correct position after the individual satellites have more separation.

How exactly are you filtering that? Box filter? Gaussian? Infinite impulse response lowpass? FFT and then masking in frequency domain?
-
Not caught = bad news
I disagree. Broken fairings = bad news. Fishing them out of water and reusing them isn't as cool as two autonomous vehicles coordinating a net landing, but isn't to the point of "bad news".
Have a good one,

Simple down sampling. Tried a few methods, most introduced artifacts and distortions not consistent with physics.

The thing about broken fairings is we usually don't hear what caused the mission to fail. Looking at the NOAA bouy data for 41002 it seems there could have been some instability with winds near the LZ. But, it could have simply been hardware failure. 1/2 #SpaceXFleet
https://twitter.com/julia_bergeron/status/1302224607634751491
Bouy 41001 to the northeast shows a similar pattern but without the spike ahead of launch. Without weather balloon data we don't know upper level wind conditions. They did collect the remains so I'm sure SpaceX will learn from the loss regardless of the cause.
