It looked like the landing was going to be off-center a lot.

Another launch from California in a few hours.  I will be sleeping.

There seems to normally be a significant sidestep towards the end of the deceleration phase of landing.  I’d love to know more about their landing control algorithms, but I suspect there’s a lot of proprietary knowledge there they prefer not to share.

I would also love to see a distribution of landing points vs target.  Very, very few hit dead center, but it seems that most  land less than halfway from the center to the ring.

It may be that the impact point after the entry burn misses the boat then once the landing burn is going OK they do that side step to land on the boat.

I suspect you are correct - that part seems too consistent not to be.

It almost seemed like this last landing ended up offset towards the stern instead of to port (I’m only remembering initial port offsets, but there may also be starboard offsets I’m not remembering).  I’m speaking of the primary deceleration before the final sidestep to the pad.

"Nice rocket company you have there. It'd be a shame if something were to happen to it..."

https://www.cnbc.com/2023/08/24/doj-sues-spacex-alleging-hiring-discrimination-against-refugees-and-asylum-seekers.html
The U.S. Department of Justice sued SpaceX on Thursday, alleging Elon Musk's space company discriminated against refugees and asylum seekers in its hiring practices.

The lawsuit says between 2018 and 2022, SpaceX "wrongly claimed" that export control laws limited its hiring to U.S. citizens and lawful permanent residents.

The DOJ has been investigating SpaceX since June 2020, when the department's Immigrant and Employee Rights Section received a complaint of employment discrimination from a non-U.S. citizen.

"Our investigation found that SpaceX failed to fairly consider or hire asylees and refugees because of their citizenship status and imposed what amounted to a ban on their hire regardless of their qualification, in violation of federal law," Kristen Clarke, assistant attorney general of the DOJ's Civil Rights Division, said in a statement.

Clarke added that the DOJ's investigation found "SpaceX recruiters and high-level officials took actions that actively discouraged asylees and refugees from seeking work opportunities at the company."

The Starlink 6-11 mission may slip to late on 26 August 2023 but no official word yet.  Crew-7 is assumed to be the priority launch.

Update:  It did.  My belief is that the review to OK a manned NASA launch includes a review of the previous launch of the booster...in this case Falcon 9.   If they launched Starlink 6-11 tonight perhaps they would have to evaluate the launch data before they could re-approve the launch of Crew-7 six or seven hours later.    Timing might not allow it thus Starlink 6-11 is delayed until after Crew-7 launches.  Again, this is my understanding and I could be wrong.

If this launches at 1:05 UT (27 August 2023) then parts of  Colorado, Arizona and New Mexico may have a great pass just after payload deployment.

1)  For the Colorado Springs area, there is a 15 degree elevation pass with maximum elevation at 8:38:32 PM MDT in the southwest (moving from west to east).

2)  Tucson AZ has a 67 degree elevation pass rising in the WNW (azimuth 303 degrees) at 734 PM MST.  It passes through the Big Dipper handle around 7:37:20 PM.   Maximum elevation is at azimuth 30 degree at 7:38:20 MST.

3)  For the Albuquerque NM area, the objects rise in the WNW at 8:35 PM MDT.  Maximum elevation of 36 degrees is at azimuth 213 degrees as it passes over the constellation Scorpius.  Shadow entry is soon after it passes just above the moon.

4)  El Paso TX has a 77 degree elevation pass with maximum elevation at 8:39:15 PM MDT at azimuth 215 degrees.  Going east the skies are darker so that should help those locations.  

Shadow entry at around 8:40:08 PM MDT (7:40:08 MST).

The Starlinks should be closely grouped with the second stage visible.  Binoculars could be helpful.   Since re-entry occurs to the east of South Africa, the deorbit burn and propellant tank ventings have to happen at some point after deployment and possibly visible to the states mentioned.  Without knowing the time for the events, I suggest that interested people check for local passes and go look.

Personally I am using Heavens-above.com.   Change the location in the upper right and click the link for your passes.

I will add more to this post as I get it.

Thanks to Dr Kelso for the element sets that allow these passes to be predicted and Heavens-Above.com for making the pre-launch predictions possible.

The 7:45 PM EDT launch time is not optimal for jellyfish sightings but I have seen some decent effects during a launch at sunset.  Later launch times may not be great for the booster portion but can still good for the second stage firing.

Look at Post #33 above.   People were able to see the post venting of second stage propellants from the Starlink 6-11 launch.  If it appears that the same is possible from this launch, I will start a new thread on it and post the same info in a separate post in this thread.  With a 8:40 PM EDT launch I have a 16 degree pass around 8:12 - 8:16 PM MDT.

California should see it starting around 8:47:15 PM PDT at azimuth 292 degrees.  Moving to the southeast with maximum elevation around  azimuth 215 degrees and elevation 74 degrees.  Shadow entry around 8:82 PM PDT.

This is from Sacramento CA.  If you are north it will be a little lower.  South at some point it will be overhead then further south getting lower but to the north of overhead.

Deorbit burn and propellant venting should be looked for.
