Refueling is standard procedure for the ISS. These days that's mostly handled by the Russians though.

I was thinking free-flying spacecraft to free-flying spacecraft.  I'd think that would be a bit different.

NASA has been looking to demonstrate a remote/robotic servicing mission (which may include refueling) for some time but the money's never been approved. There have been rumors that X-37 was going to test tech for refueling recon sats but so far scant evidence.

Interview with Aerojet Rocketdyne manager covering development of the AR-1 engine including some details on technical design and operational performance.  The picture on the wall is not an F-1 and is briefly discussed around the 15 minute mark.

Thanks for that. He actually mentions the M-1 engine in the painting at the 13-minute mark. He starts discussing the F-1 at the 15-minute mark.

Progress refueling ISS is free-flying spacecraft to free-flying spacecraft.  Just because ISS is more massive doesn't change anything.

And here is the competing BE-4 engine from Blue Origin.  Rated at 550,000lbs thrust and scheduled for flight readiness by 2019.  Unlike Aerojet, no tax dollars are being used.

Razzmatazz from ULA in response to Spacex.

They have an hour long panel discussion of future space development posted on their Youtube channel as well.

Initial BE-4 test results in "lost powerpack".  Sounds like a vague definition for an engine explosion although it isn't clear in the article if the rocket was actually in full operation and generating thrust.

https://spaceflightnow.com/2017/05/15/blue-origin-encounters-setback-in-be-4-engine-testing/
"Blue Origin said Sunday that it lost a set of powerpack hardware for its BE-4 engine during a ground test mishap, dealing at least a minor setback to the development of a powerful U.S.-made propulsion system that United Launch Alliance says is the leading candidate to power the first stage of its next-generation Vulcan rocket."

"Powerpack" apparently covers the parts of the engine upstream of the main injector.  So this sounds like the didn't destroy the injector or combustion chamber.  Could be they shredded a turbopump or something else that is a little less energetic than blowing up the whole engine.
