Lots of quotes and info here, thanks to Philip Sloss, who is at Stennis for test six of seven (covered in the RS-25 update thread)....but this is worthy of a standalone article.

Excellent primer article for the test Philip, lots of meaty details!

Huh, something I didn't know (and previously thought about):

“We run (the engine test) off of facility liquid oxygen run tanks and fuel (liquid hydrogen) tanks, but we also have interconnected piping that allows us to back-feed those systems during a hot-fire from barge tanks."

Nice article Philip!

Great article. This engine will be so well tested and understood within the context of it's new role, that I really look forward to what they'll be able to do with the next expendable version. 

Regardless, 4 instead of 3, directly under the tanks as opposed to the shuttle off-set and all sitting between 7 Million pounds of SRB hell on earth. This is going to be one hell of a show.
