Yes, a launch or two ago the conditions were just right an the LV 'disappeared' for a split second!
I'm not the only member who'd thought that he'd witnessed a R.U.D.

Last 2 landings now have shown some pretty aggressive grid fin activity , like full deflection activity.
Something's up with that.

There was a good explanation about that in this thread before, it's happened several times.
I'm not sure if it was a piece of ice but I believe that it came from the booster.

Here is some information on payloads on the upcoming Transporter 2 launch

Who’s onboard SXRS-5 (SpaceX Transporter-2)?

I am seeing conflicting launch times.

The first stage may return to land instead of a drone ship recovery.

Info on the Sherpa OTV

I have not found a picture of the payloads ready to go or an animation of the deployment sequence.

Here is a graphic of the hazard zones for the upcoming Transporter 2 launch. The zone to the east of Miami could be for the first stage but one source suggested that it may land near the launch site.

The zone closer to Cuba may be the fairing.   Note that there must be a dogleg maneuver probably by the second stage that changes the inclination closer to 97 degrees (sun synchronous).

There should be a fairly substantial difference in the landing profile depending on the mass they're launching and what orbit it's going to. A heavy payload to a high orbit likely has the booster doing more work - getting higher and/or faster than a light payload to a light orbit.

SXM-8 shows (in Wikipedia) as a 15K satellite to GTO. Wikipedia would also tell you that a Falcon 9 can only push 12k to GTO without expending the core, so clearly they're doing something there to get SXM-8 all the way up. The point is, that one was almost certainly near the edge of the recovery envelope and probably came in pretty hot.

GPSIII-05 was a 9600# satellite to MEO. The GPS constellation is at 12,500 miles, so it's pretty high. GPSIII-02 went up on a Delta IV (all the others were on F9's), but the DIV needed 2 strap on boosters to make it, and the RL-10's on the DeltaIV upper stage should be more efficient than the F9's upper stage at getting the satellite into that high an orbit. (The RL-10, while lower thrust than the Merlin, is VERY efficient, with a higher Specific Impulse than the Merlin. That should really help to launches above LEO.) To get to that orbit, they should again have to go steep (DIV would likely go steep because of the low thrust of the RL-10) or fast to let the second stage get to that high orbit.

My point is that we're so used to watching Starlink or Dragon Launches - which are both pretty easy for F9 - that we forget that sometimes they're launching something a little more kinematic. I'd bet that if you looked at SXM-7* or a previous GPSIII launch, they would have been similar to the last 2.

Transporter 2 is an odd one, too, because it's going to Sun-Synchronous orbit. But it's smallsat rideshare - they've probably got that booster right in the middle of it's comfortable performance range, especially if it's returning to the Cape from that launch angle. It would need some performance available to do that.

*-ETA:I looked up SXM-7. They launched it into a highly elliptical orbit and the satellite used it's thrusters or a kicker to get to it's final orbit in GEO. So that's the something I alluded to above. That was probably cheaper than expending a F9 core, which could do it without any tricks.

Initial GPS 3-05 orbit was 394 x 20174 km.

Initial SXM-8 orbit was 235 x 19380 km, 26.5 degree inclination.

Thanks for that , very good insight.

The RTLS should be quite spectacular with the booster following the coast line from the South , I hope it's clear !!!

SpaceX drone ship Of Course I Still Love You arrives at Panama Canal

"Ten days and one unexpected detour after SpaceX drone ship Of Course I Still Love You (OCISLY) departed Port Canaveral, Florida for what could be the last time ever, the ship has arrived at the Panama Canal.

The five thousand mile (~8000 km) journey began almost exactly on June 10th and saw drone ship OCISLY towed to the Bahamas – an unanticipated development. Unlike drone ship sibling Just Read The Instructions (JRTI), which made the same journey in reverse about a year and a half ago, OCISLY was loaded onto the deck of large semi-submersible transport ship known as Mighty Servant 1 (MS1). Normally used to transporting entire ships and oil and gas equipment weighing tens of thousands of tons, a SpaceX drone ship – while still huge – is a featherweight load in comparison."

It looks like they consistently land slightly off center to one place. That must be on purpose and not just messing the center by a little.

They could be aiming slightly upwind in case of a last-second gust I'd guess.
