Is there a publicly available spreadsheet containing data on the tests at McGregor? At minimum, engine type and firing duration that is shown on NSF Live?

Is this what you are looking for: https://mcgregor.nerdpg.live/dashboard?

And I have F9 on the brain, given all the launches. This is a Falcon Heavy core.

Check out this SpaceX Raptor engine tested with the nozzle pointed slightly up! I believe this is a Raptor Vacuum engine judging by the width of the exhaust flame.

In his defense he posted that long before SX referred to it as Gimballed, maybe might have thought the engine test mount was inclined. :shrug:

Cool to be able to link both views, it's not too often you get a spacex test video that can be definitively linked to the NSF version.

Don't see any mach diamonds.  Maybe a Raptor vacuum without the full nozzle?

Crazy conditions during yesterdays raptor test on tripod showing some interesting interactions between the vapor and the shockwaves!  2 different angles for your viewing pleasure.  @NASASpaceflight

Tripod looks to be ready again so watch testing LIVE at: nsf.live/mcgregor

What is the last glimpse weve had of the methane thrusters?

That's easy: the artist's impression when NASA gave SpaceX the HLS Option A contract.

I recall a somewhat recent comment by Elon that they were going to try and get away with only the Raptors.  That made me think they had not put alot of work into the unseen thrusters.

Myself, I like the idea of a staged combustion MethLOx powerhead in the engine area with liquid LOx and Methane lines up to the thrusters, then Pintle injector thrust chambers.

Yes there would be a lot of frictional losses, but the mass flow rate wouldn't be that high for the final landing burn. 

Staged combustion would help preserve the autogenous pressurization system and SpaceX knows how to make pintle injector combustion chambers.

Coming up with a SS test rig for McGregor to test this exhaustively would be a perfect use for the test site.
Wildly optimistic prediction, Superheavy recovery on IFT-4 or IFT-5 (Welp a little early on IFT-4, but still have a shot at 5)
