Expect the eventual fallout from all of SpaceX's experimentation with reflectivity and effects to terrestrial observation assets to result in an eventual US and then later an International set of standards for all new sats in Earth orbit. This will be a big gain for the terrestrial astronomical instruments usage. But for even more advanced observations will likely move out into space beyond most of the objects that are in the way such as placed out at Lagrange  Earth-Sun 2 past the Moon's orbit and is permanently facing away from the sun. This is beyond the Lagrange Earth-Moon 2 point.
Most observations can't and won't move out into space. The cost of a space based observatory is HUGE compared to an equivalent ground based one. And just for the record, launch cost has no impact on this. Free launch won't change this.

My bold.

Do you have links to actual numbers I can do research on?  Published reports, etc.  Also interested in $/minute of actual observation time for different types and locations of terrestrial observatories.  Thx.

Since this is not really Starlink specific, a PM is probably more appropriate.

I can just someone requesting fire support.
Reply would be "can you hold on for 3 hours while spin up the gun".

This would NOT be for fire support. It would be for strategic, precision destruction. It would go after the sorts of targets the Ukrainians are firing HIMARS at (bridges, ammo depots, command centers, etc.), and those don't move. So rate of fire isn't really a concern for this sort of weapon.

The use of 20-something actors to portray experienced astronauts
Yeah, these are the same casting decisions that always had actors portraying WW2 GIs (who in real life were in their early 20s) who were actually well into the 30s or 40s.
Berger tweet:
SpaceX confirms it will go for its third launch in 37 hours today with the Intelsat G-33/G-34 mission. Commercial mission is on first stage previously flown 13 times. I believe this is a record for most rapid succession of three launches in a single rocket family.

Omani satellite is called Aman.

On Tuesday, 4th October, the first Omani satellite, Aman, was successfully prepared for its launch into the Low Earth Orbit, at Newquay, Cornwall, in the UK.

Seems like there should be time to do it mid/late Oct and allow time for JPSS [launching on] 1 Nov?

So has it been delayed? And if so, do we know why?

IDK why the NextSpaceFlight listing has vanished.  ???

Depending on how one counts, SpaceX is just 2-4 launches away from completing Shell #4. I'm not actually sure if the FCC deployment requirements specify that all planned satellites have to be concurrently working in orbit, or merely launched at some point. If the latter, then SpaceX is exactly two 54-satellite launches away from having launched 1584 Group 4 satellites.

I personally suspect/hope that SpaceX will actually ensure that it has the maximum possible number of working satellites in orbit, which would require ~4 more launches. In that vein, Group 1 may also need 2-3 more launches to be truly complete. But it's entirely possibly that both Group 1 and 4 can be considered practically complete after just a few more launches.

In an IPO-Edge webinar this afternoon, Virgin Orbitís Dan Hart says they are still working with the UKís CAA for a launch license for their mission from Spaceport Cornwall. Will be releasing a target launch date in the next several days.

Hart adds that the companyís plan remains doing four launches this year (two completed so far), but the focus now is getting through the UK launch. After that, will see if the company can get a fourth launch in this year.

F9/Crew 5: At 2pm EDT, Crew Dragon was 30 kilometers behind the ISS and 2 kilometers below; approach initiation burn expected at at 3:27pm at a range of 7.5 km; Mann: "We've got a good view of station already, it was looking pretty beautiful out the window"

The Crew Dragon spacecraft continues to fly smoothly and is approaching its arrival at the ISS. In the long-term stay on the ISS, which is about to begin, I will do my best to show the results of the utilization of the Kibo Japanese Experiment Module. We will continue to spread the wonders of the universe in various ways, so please look forward to it.
