Thread for Starlink v1.0 Flight 9.  This is a Starlink rideshare mission.

Check the Starlink Index Thread for links to more Starlink information.

NSF Threads for Starlink v1.0 Flight 9: Discussion

NSF News Articles for 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 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 9ís 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 Earthís 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.

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
Starlink-7 (V1.0 L6) in April 2020

GO for launch, GO for age of reflight

SSLV launch is now flying sats 7-10 due to launch delays. SSLV sat assignments will keep shifting to the right until SSLV enter its launch campaign.

EDIT: Just recently updated as such on Skyrockets website.

Copy/paste from the Starlink v1.0 L8 thread.  Copy/paste so this thread OP remains the thread OP.
Starlink launch 10, there seems to be no dedicated thread yet

SFN 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 canít believe the pace theyíre on. We waited and waited for a booster to get to a 5th flight, and now weíre 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)

Quote
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.

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.

This is now the next SpaceX orbital launch.

Are there any sign of launch preparations at 39A?

If they are going to skip static fire again, you won't see any activities until the last two days.

Wow...this pace is breathtaking...have we finally reached the point of rocket launches becoming as common and ordinary as commercial airlines ...?

Itís all fun and games until someone loses an eye..or a Falcon 9.....

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.

Of only there were bus tours at 39A we could see if they replaced the top insert on the strongback from Crew Dragon configuration to fairing configuration but... we won't know

Fairing-catching net-ships now set a minimum time between launches of three to four days, ... assuming both launches use fairings.

In pre-Corona virus times, there were over 9k airliners flying around at any given time.

So, no.

But the pace is still impressive.

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 itís 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?

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 arenít 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.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

They could be just pieces of black cloth.
