Will there be a Static Fire before the launch of Starlink v1.0 Flight 26?

The first stage will be 1058.8.  Launch is currently scheduled for May 15.

Edit May 14: Apparently, no.

No Static Fire. LV erected on the EDT afternoon of May 15.
Also May 15 EDT: A successful launch and first stage recovery on ASDS.

Will there be a Static Fire before the launch of Dragon SpX-22?

I suspect yes.  It's a Cargo Dragon flight.  And, it will be the first flight for first stage 1067.

Wrong.

Complete stack erected afternoon and evening of June 1 EDT.  No Static Fire.

Will there be a Static Fire before the launch of SXM-8?

It will be the third flight for first stage 1061.  Therefore, I doubt it will be static fired.

Likely statistics told them that most times there are not issues on the pad. The pad availability is the no.1 launch capacity constraint right now, makes sense trying to optimize it.

Pro of not doing a static fire on pad:
- Saving time on a shared resource, the pad, if everything is ok.

Cons of not doing a static fire on pad:
- If there is an issue with the vehicle or GSE that scrubs the launch that would be caught by a static fire, a lot more time is spent on the pad, and a precious launch window was wasted. Plus additional mission and range costs.

- Slightly higher risk if an issue not causing abort would be caught during post-static fire review.

Statistics should have data on the cons, and they concluded that no static fire is most efficient at this time.

Wrong again!  Launch vehicle, minus payload, went to the pad in the afternoon EDT, June 2nd.  Static fire at 2:30 am EDT, June 3rd.

EDIT June 3: Did Sirius pay for a Static Fire?

EDIT June 6: Successful launch and first stage ASDS landing.

I am too lazy to check, but I am pretty much (sic) sure that static fire is determined by the launch pad availability over anything else. If they erect booster in time and have space (nothing being "scared" on other pads) and time for relaunch they do static fire. It's simple as that. Old, new,repaid booster doesn't matter.
I've mentioned the reason  already.

Will there be a Static Fire before the launch of GPS III-5?

It will be the second flight for first stage 1062.  Therefore, I doubt it will be static fired, UNLESS the Space Force is paying for a Static Fire.

Will there be a Static Fire before the launch of Transporter-2?

It will be the eighth flight for first stage 1060.  It will also follow the previous launch from SLC-40 by seven days (as of this posting).  I doubt it will be static fired.

Wrong!  Successful static fire afternoon EDT June 22, now three days before scheduled launch.

Successful launch and first stage LZ-1 landing on June 30!

July?
Are you sure about that?
I only ask because July 22 is my birthday, and well, today is not my birthday.  :P

Will there be a Static Fire before the launch of SpaceX Dragon-23?

As of this posting, 4 days before launch, we don't know what booster will be used. The LV has not yet been transported to LC-39A.

Is 1051 still in Florida? Or was another first stage taken to Vandenberg in its place? Or, it could be 1058.9, 1060.3, 1061.4, 1063.3, 1067.2.

1062.3 will launch Inspiration4 next month.

We also don't know yet if there will be a Static Fire.

The LV for CRS-23 has been rolled out. And yes, there will be a static fire. B1061.4 will be the booster according to Nextspaceflight

Successful B1061.4 SpX-23 Static Fire evening August 25 EDT.

Edit August 29: Successful launch and first stage ASDS landing on morning of August 29 EDT.

I expect yes, as part of the preparation for a crewed Dragon flight.  First stage is 1062.3.

Considering this is such a valuable mission, including humans, I would imagine they will do a firing.
