Are there many single heavy polar loads on the horizon, anyway? Iridium was so heavy because they sized the packages just right for F9 ASDS, same for Starlink. If there are significant savings in launching from the east coast, any large rideshare can be split into more launches.
Which booster has the most soot? SpaceX booster launch history! (discussion)

I polar corridor FH flight will be very tricky, where would they recover the FH core? They go pretty far down-range. A drone ship parked right off the coast of Cuba? :-) No, Iím not sure it is practical to use FH for this.

Maybe right off Gitmo  ;)

Discussion of FH landing really should move to another thread, this is a mission thread for a Falcon 9 launched payload.

Spaceflight Industries shows a flight on their list of available rideshares that sounds a whole lot like this one.

SAOCOM 1B is ready for launch campaign
Quote
Between November 27th, 28th and 29th, CONAE and INVAP completed the testing of the unfolding and folding mechanism of the SAOCOM 1B SAR antennas, completing the testing program. Only needs to verify its software and to perform the last propulsion subsystems checks, to be readied for transport to its Florida launch site. The schedule calls to have the satellite and support equipment packed and ready for transport before New Year.

This seems to be the first confirmation I've seen of rideshare payloads on the flight.

[Space News] Capella Space to launch seven radar satellites in 2020 as it prepares for commercial operations
Quote
WASHINGTON ó Space-based radar imagery provider Capella Space will launch seven satellites and start commercial operations in 2020, the company announced Dec. 16.
...
The first satellite, to be named Sequoia, will launch from Cape Canaveral in March into a polar sun-synchronous orbit on a SpaceX rocket.
...
The new satellite design, at under 100 kilograms, is larger than the original 40 kilogram design.

Is SpaceX gonna do all polar-orbit missions from the Cape starting with SAOCOM 1B?

As many as they can. (not all payloads are this light) It could also be a demonstration one-off to prove they can.

Staff, Fairing and ASDS support makes sense to use CC.  By the end of 2020 if Starlink is really flying every 2 weeks then they may prefer the availability in VAFB for such launches. 

It will be a great show for south Florida.  Iím really excited for this one.
Starship 2022, can't wait!!

Re: SAOCOM-1B launch time of day
https://directory.eoportal.org/web/eoportal/satellite-missions/s/saocom
Quote
Orbit: Sun-synchronous near-circular orbit (frozen dawn/dusk orbit), altitude = 619.6 km, inclination = 97.86ļ, period = 97.1 minutes, repeat cycle of 16 days (8 days for the constellation), LTAN (Local Time on Ascending Node) at 6:00 hours.

SAOCOM-1A was launched during local (Vandenberg) dusk and the Falcon 9 produced a spectacular visual display.  Weather allowing, the folks along the south Florida coast and in Cuba should also experience this.  There hasn't been such a launch of these circumstances in decades; some heads-up for the locals would be in order as the launch date approaches!

When is the exact launch time based on the SAOCOM link?

Yeah, I don't think that link is talking about launch time of day, it's talking about the local time of day of the sun-synchronous orbit, once it gets there.

PSA #1: EST does NOT mean "Eastern Time".  Use "Eastern" or "ET" instead, all year round, and avoid this common error.  Google "EST vs EDT".
PSA #2: It's and its: know the difference and quietly impress grammar pedants.  Google "angry flower its" .

It should launch at a similar time to SAOCOM-1A, which launched south to match the "dusk" part of the dawn/dusk orbit.

PlanetIQ is preparing to launch its first small radio occultation satellite into polar orbit in March on a SpaceX Falcon 9 rocket. The firmís second satellite is scheduled to travel in July into dawn-to-dusk orbit on Indiaís Polar Satellite Launch Vehicle.

From a business standpoint, PlanetIQ is doing well after raising $18.7 million and winning contracts from NOAA and the U.S. Air Force, said Michael McCarthy, PlanetIQ chief revenue officer.

PlanetIQ plans to fill out its constellation quickly, launching 18 to 20 radio occultation satellites between mid-2020 and mid-2022.

The first polar orbit launch from Florida since 1960 is scheduled for late March, when Argentinaís SAOCOM 1B radar observation payload will take off from Cape Canaveral, not from Vandenberg as originally planned.

That's a really good question.
Don't suppose they can have the returning first stage fly over Cocoa Beach, Port Canaveral, and CCAFS.
Shouldn't it be low cost, in terms of additional thrust required, to do that as part of  the entry burn by tilting towards the coast?
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Maybe not, if S1 flies the first part of the leg and S2 then does the rest.  No idea where in the S1/S2 profile the trajectory change would come, myself.

I think most (if not all) of dogleg is done by the S2. You really want to leave the atmosphere as fast as possible. Once you did that, you can add velocity much more efficiently and in pretty much any direction.
