For the question to resolve "YES" a Starship must receive propellant from another spacecraft:
A test counts.
Any amount of propellant transferred counts.
It must survive the refuelling.
@Mqrius Oh, interesting. Yeah, the question is about external refuelling since an internal transfer does not help with flight economics
@lukres Yeah, the test would mostly be about verifying that they can settle the propellant and use pressure differences or Gforces to get the propellant to transfer. But when they do it, it would be the first solid step towards orbital propellant transfer.
@lukres That will be an internal transfer between the header tank and the main tank of a single Starship, actually. That's not from one vehicle to another so it wouldn't count yet. But yes, exciting development!
