NSF Threads for SXM-8 : Discussion (https://forum.nasaspaceflight.com/index.php?topic=52196.0)
NSF Articles for SXM-8 : https://www.nasaspaceflight.com/2021/06/sxm8-launch/
Launched successfully 6 June 2021 at 12:26am EDT (0426 UTC) on Falcon 9 (booster 1061.3) from CCSFS SLC-40 to GTO. ASDS landing achieved on Just Read the Instructions, towed by tugboat Finn Falgout. Recovery support ship was GO Quest. Fairing recovery of both halves from the water accomplished by GO Searcher and GO Navigator.
SpaceX is targeting Sunday, June 6 for Falcon 9’s launch of the SXM-8 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The one-hour and 59-minute launch window opens at 12:26 a.m. EDT, 4:26 UTC, and a backup launch opportunity is available on Monday, June 7 with the same one-hour and 59-minute launch window.
Falcon 9’s first stage booster previously supported SpaceX’s Crew-1 and Crew-2 missions, which launched astronauts to the International Space Station. 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.
SSL Selected to Provide Two Powerful Satellites to SiriusXM (https://sslmda.com/html/pressreleases/pr20160728.php)
PALO ALTO, Calif. – July 28, 2016 — Space Systems Loral (SSL), a leading provider of innovative satellites and spacecraft systems, today announced that it was selected to provide two high power satellites to SiriusXM, the world’s largest radio company measured by revenue. The next generation satellites, SXM-7 and SXM-8, will replace the XM-3 and XM-4 satellites in 2019 and 2020, respectively, and will help ensure continuous and reliable delivery of SiriusXM’s audio entertainment and data services to more than 30.6 million subscribers across North America.
“SiriusXM provides an unparalleled variety of audio entertainment for radio listeners in North America,” said John Celli, president of SSL. “We have a long history of working with SiriusXM to develop some of the world’s most advanced satellites, which broadcast to cars and radios for the home, office, and mobile devices. We are honored to be selected to build two additional satellites that will reinforce and augment the fleet’s capability.”
Both SXM-7 and SXM-8 will operate in the S-band spectrum. Each satellite will generate more than 20-kW of power and will have a large unfurlable antenna reflector, which enables broadcast to radios without the need for large dish-type antennas on the ground.
SSL has previously built a total of seven satellites for SiriusXM, including its first generation Sirius satellites, which were launched in 2000. Of the seven satellites built, one was a ground spare that was never needed due to the reliability of the original constellation. It was donated to the Smithsonian Air and Space Museum in 2012.
“We are pleased to once again collaborate with SSL on two advanced satellites that will bolster service to our subscribers for years to come,” said Bridget Neville, vice president of satellite and terrestrial engineering and operations at SiriusXM. “SSL is a premier designer and manufacturer of reliable communications satellites, with the technological capability to meet our demanding requirements. We look forward to working together on the new satellites.”
SXM-7 and SXM-8 are based on the powerful SSL 1300 platform, which has the flexibility to support a broad range of applications and technology advances. The satellites are designed to provide service for 15 years or longer.

In order to ensure continuity of service to its customers, Sirius XM has entered into contracts to build and launch two next-generation satellites, SXM-7 and SXM-8. Sirius XM proposes to operate SXM-7 at 85.15° W.L. and SXM-8 at 115.25° W.L., but the two satellites are technically identical and each is capable of operating at either of these orbital locations. Sirius XM currently plans to launch SXM-7 in late 2019, with operations commencing in the first quarter of 2020, and plans to launch SXM-8 and commence operations in mid-2020. Prior to commencing operations, each satellite will undergo IOT at 120° W.L., which will allow Sirius XM to verify the performance characteristics of the spacecraft prior to deployment.

[Maxar] Preparing for Launch: SXM-8 Arrives at Launch Base (https://blog.maxar.com/earth-intelligence/2021/preparing-for-launch-sxm-8-arrives-at-launch-base?utm_source=twitter&utm_medium=organic)
By: Maxar Technologies | 05.06.2021
The latest Maxar-built geostationary satellite for SiriusXM, the leading audio entertainment company in the United States, has arrived at the SpaceX launch base in Cape Canaveral, Florida. SXM-8, a high-powered digital audio radio satellite, will now be integrated with a SpaceX Falcon 9 rocket in preparation for launch.
The satellite, which weighs almost 7,000 kg during launch, is built on Maxar’s 1300-CLASS PLATFORM. SXM-8 is designed to provide service for 15 years or longer. Once on orbit, SXM-8 will unfurl its large antenna reflector, visualized in yellow in the rendering below. This reflector will allow SiriusXM programming to reach mobile radios, such as those in moving vehicles.
“Maxar and SiriusXM have a decades-long relationship, and we’re thrilled to deliver the ninth satellite we’ve built for them since 2000,” said Paul Estey, Maxar’s Executive Vice President, Space Programs Delivery. “SXM-8, built on Maxar’s proven 1300-class bus, is more than twice as big and powerful as the first-generation SiriusXM constellation built by Maxar.”

Sirius/XM Satellite Radio’s Sirius-FM8 launches from the Kennedy Space Center on a SpaceX launch vehicle on June 1st, 2021. USN will support the In-Orbit-Testing (IOT) when the spacecraft is parked at 120.5 degree. The IOT will nominally last for 21 days with an additional 9 days of contingency.
-
The booster will almost certainly be B1060.8, but the addition of L28 on May 26 might indicate the launch is already slipping.
They are both using SLC-40 with only a 5.5 day turnaround. Tight ASDS turnaround with CRS-22 as well.

FALCON 9
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the next batch of Starlink internet satellites from pad 40 on May 26 at 2:59pm EDT. A Falcon 9 from pad 40 will launch the SiriusXM-8 communication satellite on June 1 at 12:25am EDT. A Falcon 9 from pad 39A will launch the next Dragon resupply mission, CRS-22, on June 3 at 1:29pm EDT. Upcoming launches include more batches of Starlink satellites. And a Falcon 9 will launch the fifth block III GPS satellite for the U.S. Air/Space Forces from pad 40 on June 17, sometime between 6-9pm EDT.

Still no clarity on SXM-8 launch date; cross-post:
https://www.floridatoday.com/story/tech/science/space/2021/05/27/spacex-ula-gearing-up-intense-florida-rocket-launch-cadence/7457144002/
Finally, SpaceX's most tentative launch of June appears to be SiriusXM's SXM-8 mission, originally slated for the first day of the month. It could still fly from LC-40 in the first half, but little else was available as of late Thursday.

Falcon 9 B1061-3 is at pad 40 for a static fire test later today. It can be seen from NASASpaceflight's Fleetcam.
The top of the Falcon 9 looks blunt, not conical.
If there is to be a Static Fire tonight EDT, then it will be without the payload.
Personally I'm surprised that they're doing a Static Fire. But given that, it's not a surprise that it would be done without the payload.
-
LOX loading for static fire has already started, T-0 is expected at 03:26 UTC.
Indeed, the Falcon 9 does not have the built-in payload.

What is a Debris Cloud ?
It's the exhaust clouds that were formed during the CRS-22 launch. They're just hanging in the air as of now.
?
I think debris cloud rule is similar to detached anvil rule: the decaying remnants of a thunderstorm.
Here's a quote from a paper that I found on-line: Scale Dependence of Monsoonal Convective Systems over the Indian Ocean
https://journals.ametsoc.org/view/journals/clim/13/7/1520-0442_2000_013_1286_sdomcs_2.0.co_2.xml
...[T]he background convective cloudiness, might as well include some tops of midlevel cloud systems, isolated thick cirrus, or detached stratiform anvils of decaying convective clouds, and can be thought as the so-called convection debris that is often encountered during the winter monsoon over the Indian Ocean region...
-
Actually for this case it’s probably from 14 CFR Appendix G to Part 417 - Natural and Triggered Lightning Flight Commit Criteria. These are part of the Commercial Space Transportation regulations from the FAA.
Debris cloud means any cloud, except an anvil cloud, that has become detached from a parent cumulonimbus cloud or thunderstorm, or that results from the decay of a parent cumulonimbus cloud or thunderstorm.
The specific rule is from NASA’s Falcon 9 Launch Weather Criteria chart isDo not launch within 3 nautical miles of a thunderstorm debris cloud, unless specific time- associated distance criteria can be met.

SpaceX is targeting Sunday, June 6 for Falcon 9’s launch of the SXM-8 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The one-hour and 59-minute launch window opens at 12:26 a.m. EDT, 4:26 UTC, and a backup launch opportunity is available on Monday, June 7 with the same one-hour and 59-minute launch window.
Falcon 9’s first stage booster previously supported SpaceX’s Crew-1 and Crew-2 missions, which launched astronauts to the International Space Station. 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. A live webcast of this mission will begin about 15 minutes prior to liftoff.

Both fairing halves are brand new.

Inside the web page it does not appear in what time will be the fairing separation, at first I thought it was because the client does not want it, but we have seen the satellite before so maybe it is an error, there is also an error in the Homepage.
According to the launch of SXM-7 where some times are the same, the fairing separation would be in T+03:37.

Is your @SIRIUSXM coming in clear?
The next generation #SXM8 satellite has been deployed, and will continue to make its way to geostationary orbit before going into service.

Falcon 9 punches a hole in the cloud layer, and then lights it up!
Typically, clouds are a bummer when watching a launch, but the way those 9 Merlins lit up that thin cloud layer looked really cool, as they pushed @SIRIUSXM's #SXM8 satellite to orbit!

Liftoff!
At 12:26am (ET) Sunday, #SpaceX launched the #SXM8 satellite atop a flight-proven #Falcon9 rocket. Minutes later, the booster was successfully recovered.
This was the (cloudy) view from Palm Shores, 25-miles south of the pad.

There is not much to separate the telemetry for SXM-7 and SXM-8. The biggest difference I see is that the SXM-8 second stage flew with a bit more loft, but to the same injection parameters.

Ken the Bin noted earlier that the updated timeline showed the fairing deployment some 14 seconds earlier on SXM-8 compared to SXM-7. Maybe the increased lofting allowed the earlier fairing deploy? I wonder if that helps with fairing recovery by reducing re-entry velocity?

Indeed, usually its only Starlink missions that omit the acoustic tiles. There is nothing preventing other satellites though from being made compatible with that same acoustic environment though. It does save mass
-
But why else do Starlink missions eliminate the acoustic tiles besides shave off dry mass?

But why else do Starlink missions eliminate the acoustic tiles besides shave off dry mass?
They're porous so probably absorb water after landing, requiring a lot of time to remove, clean, and replace with new insulation. Also more weight in the fairing (especially when waterlogged) increasing risk of damage when lifting/transporting.

The SXM-8 radio broadcasting satellite has been cataloged in a sub-synchronous transfer orbit of 235 x 19384 km x 27.0 deg. The heavy 7 tonne satellite is mostly propellant and will use its own engine to first raise apogee and then perigee to GEO altitude (~35800 km)

Another contributing factor could be that they have been collecting data on the Starklink missions and now know that the extra acoustic tiles are unnecessary - at least for this kind of payload.

JRTI and B1061 will be within the vicinity of Port Canaveral from around midnight tonight. They can than set up for an arrival around dawn tomorrow.
OCISLY droneship is currently occupying the parking space for JRTI so needs to be moved or depart before JRTI arrival can happen.

OCISLY is still occupying the booster unloading dock so perhaps JRTI will be berthed elsewhere.

Edit: just full disclosure here I am assuming this is 1061 and not 1067 due to timing and port activity and the booster markings appearing to match. If anyone has info to the contrary feel free to mention and I will move it to the appropriate thread.
