Also, re: earlier delays:
Coronavirus delays push back launch of next Landsat to September 2021, SFN, September 7, 2020
Quote
The Government Accountability Office, a watchdog agency, reported earlier this year that the Landsat 9 project was “experiencing ongoing delays in spacecraft electronics fabrication, flight software, and simulators that affect system integration.”
Landsat 9 officials attribute these delays to Northrop Grumman.
Quote
“The project has met with contractor management to discuss its performance, including concerns about the number and experience of staff available to complete remaining work,” the GAO said.

The GAO’s report also identified scheduling conflicts with other spacecraft under construction at Northrop Grumman’s facility in Gilbert, Arizona. Northrop Grumman allotted test equipment to another mission, which “compounded” delays with Landsat 9, officials wrote in the report.

Does anyone know/can anyone say what other spacecraft were involved in these scheduling conflicts?

Support your local planetarium! (COVID-panic and forward: Now more than ever.) My current avatar is saying "i wants to go uppies!" Yes, there are God-given rights. Do you wish to gainsay the Declaration of Independence?

L9 has completed dynamics testing at Northrop-Grumman. Observatory thermal-vacuum test is next on the schedule.

L9 has completed thermal-vacuum testing at Northrop. Next up are final electrical tests, close-outs, and reviews prior to shipment to Vandenberg this summer.

DIU is helping to fund Cesium Mission 1. As part of that mission, two six-unit cubesats are scheduled to travel to low Earth orbit in September as secondary payloads on the United Launch Alliance Atlas 5 rocket transporting the NASA-U.S. Geological Survey Landsat 9 Earth-observation satellite.

Two of the rideshare payloads.

L9 has completed its pre-ship review (PSR). Next up is shipment from Northrop (Arizona) to Vandenberg SFB in early July. Launch readiness date is still 16 Sept 2021.
Barring any spacecraft issues between now and then, that date will depend on the ULA team flying back to California following a possible late August/early September launch of STP3 from the Cape.

Volga-Dnepr has a flight scheduled to carry an Atlas V booster to Vandenberg soon, might be the booster for this flight.

The booster is expected to arrive around 28 June 2021. And should be tail number AV-092.
The Centaur and fairing are already at VSFB.
The ESPA ring arrived in mid-June.

Some more details about the launch campaign:

-Will perform a launch vehicle wet dress rehearsal (WDR) in mid-August.

-Launch targeted for 16 Sept 2021 @ 11:11 PDT (18:11 UTC) with a 30-min window.

-NASA/ULA/Range can support attempts up to end of September. If delayed further, most likely have to wait until January 2022. ULA team needs to support the NASA Lucy mission which has a firm planetary launch window beginning 16 October 2021 from the Cape.

-Flying with an extra extended payload fairing (4-meter) to accommodate the ESPA ring.

-Centaur will execute a 4-burn profile to: inject L9 into its ~685km sun-sync target orbit (burn 1); re-shape orbit to ~550km sun-sync for ride-share deployment (burns 2&3); de-orbit (burn 4).

-If launch occurs on schedule, L9 will target an under-fly of L8 in early November for cross-calibration of their instruments. L9 will then raise itself to its final ~705km orbit slot (previously occupied by L7).

-USGS assumes operational control of the mission after the 90-day on-orbit commissioning.

Do you know what version of the RL10 engine will be used on Centaur?
