Based on the fact that they actually removed two Starlinks for the planet satellites even with all the space in the fairing, is it safe to say that starlink launches are fundamentally mass limited and that any rideshare will end up in a reduction of starlink count for that launch? I can see see SpaceX charging by the starlink-equivalent for such a case.

I don't think that the removal of 2 starlink satellites was due to mass limitations. Looking at the image of all the satellites in the faring it looks like that the adapter that was designed by Planet takes the place of those 2 starlinks (1 layer of satellites) so that the entire stack is still held in place by the tension rods that are used on a standard starlink launch.
Will be interesting whether the 3 Planet Sats will be deployed before the rest, or just thrown out with their dummy starlink sat and deploy from that later? I haven’t seen a timeline for deployment anywhere.

SpaceX is targeting Saturday, June 13 at 5:21 a.m. EDT, 9:21 UTC, for launch of its ninth Starlink mission, which will include 58 Starlink satellites and three of Planet’s SkySats. Falcon 9 will lift off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, and a backup opportunity is available on Sunday, June 14 at 4:59 a.m. EDT, 8:59 UTC. This mission marks SpaceX’s first SmallSat Rideshare Program launch.

Falcon 9’s first stage previously supported the Telstar 18 VANTAGE mission in September 2018, the Iridium-8 mission in January 2019, and two separate Starlink missions in May 2019 and in January 2020. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be stationed in the Atlantic Ocean.

Falcon 9’s first stage previously supported Dragon’s 19th and 20th resupply missions to the International Space Station. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean. Half of Falcon 9’s fairing previously flew on the JCSAT-18/Kacific1 mission, and the other half previously flew on SpaceX’s third Starlink mission.

Planet’s SkySats will deploy sequentially beginning about 12 minutes after liftoff, and the Starlink satellites will deploy approximately 26 minutes after liftoff.

Hmm ... 2x first stage?

Is that better?

Note they are reusing fairings from 2 SEPARATE missions, something which has not been done before, very exciting!

Also worth noting the Starlink sats deploy 26 minutes after launch, which is interesting. I wonder if this will make S1 landing difficult?

Payload deploy doesn't effect staging.

Elon said they could do more but at the cost  of recovery. So this does show they could pack more. I want to see a FH with extented fairing hopefully with 100 to 120 Starlink launch before precursor to Starship.
Would be really cool to see more FH launches, but I'd bet it wouldn't be cheaper than two "standard" F9 launches with 60 each.

One FH launch =  3 S1 boosters to recover and refurbish, + 1 expendable S2, + one expendable, large fairing

vs.

Two F9 launches = 2 S1 boosters to recover and refurbish + 2 expendable S2s + 1 fairing recovery attempt

Which leads to the question which is more expensive?:

1 S1 refurb + fairing

or

1 S2 expended.

This mission has nothing to do with FH.  Please move speculative FH missions to another thread.

KEY POINTS

For the first time, all six members of the Air Force's 45th Space Wing launch weather team are female.

The next SpaceX launch, scheduled for Saturday morning, will see the six women decide if the weather is clear for liftoff.

"Any little girl that's looking up to us, I want to encourage you to pursue math and science and don't shy away from it," the 45th Space Wing's reconnaissance launch weather office Melody Lovin told CNBC.

SpaceX has finally updated their launches website for the upcoming launch, so I have created my own "press kit" again, based on the posted information.

SpaceX goes for its third launch in two weeks early on Saturday
Company also attempting to launch without static fire testing the Falcon 9 booster.

ERIC BERGER - 6/12/2020, 8:55 PM

Early on Saturday morning, SpaceX will go for its third launch in two weeks with another Starlink mission into low Earth orbit. This will bring the total number of Starlink Internet satellites launched to date to nearly 540.

Tomorrow’s Starlink mission, SpaceX’s ninth, is scheduled to launch from Cape Canaveral at 5:21am EDT.

58 Starlink satellites and three @planetlabs earth observation satellites are aboard. This marks the first SpaceX SmallSat Rideshare Program launch.

I will be going out fishing tmw at 3am and will be going 80miles offshore, I hope there’s a chance I’ll be able to spot the launch in some way, will be in south New Jersey. I’ll take pics if I see anything...

Does anyone know the trajectory of this mission?

Also am I right about SpaceX not doing a static fire on this booster?

The fairing on this mission is flight-proven! One half flew on the JCSAT-18 mission and the other on the third Starlink mission.

The SpaceX website doesn't mention fairing recovery for tomorrow's mission. Ms. Tree and Ms. Chief are downrange but it might not be a catch attempt.

At this point it looks like there isn't enough time for a static fire.

Starlink runs along the coast pretty well, but I'm no expert on whether you can see it or not. My uneducated guess is yes.

Falcon 9 is vertical on SLC-40 ahead of the 9th Starlink mission along with 3 SkySats for @planetlabs. This mission will utilize twice-flown booster B1059, previously flown on CRS-19 & CRS-20 for NASA.

Launch is scheduled for 5:21am EDT (0921 UTC) Saturday morning.

Definitely looks like some refurbishment going on to B1059.

I HOPE to be on the ground and watching YouTube with you all by the time SpaceX hits T-0...  ???

On Edit...
Hit a snag and launch will be delayed a while... maybe airborne when SpaceX flys... Time will tell...  :(

Later Edit... Airborne... mission is on...  :)
