I know there are programs like the Rocket Lab CryoSat, but I was wondering if there have been any tests of non-cryo propellant transfer? I know the Space Station refuels with a storable hypergol, but otherwise?

    $\begingroup$ AFAIK it's only been hypergols. There wouldn't be much point in xferring RP-1 or similar since it typically uses a cryo oxidizer. $\endgroup$ Sep 16, 2023 at 0:39

    $\begingroup$ potentially helpful will be other questions tagged with refueling and restore-l and their answers. $\endgroup$
