And Trippy was the one that was just deorbited when Dragon left the station.
Also, is Leaky already on the EOTP somehow, or is that robotics work still to be done prior to EVA?
Last night, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) in position to extract the failed Pump Flow Control Assembly (PFCS) also known as ‘Leaky’. They extracted the PFCS and stowed it on the Enhanced ORU Temporary Platform (EOTP) side 3.
I'm still unclear about Trippy and Leaky. I assume Leaky is S/N 0004, the one that was swapped out in the 2013 EVA and was originally on the P6 2B channel, but has been sitting in one of the two EATCS slots since 2013 for storage.Which P6 channel was Trippy - was it the 4B PFCS, or the 'new' 2B PFCS that was swapped in in 2013?Or do I have it all wrong?There are a total of 12 PFCS launched to date including the late lamented Trippy

It makes no sense, to send one down which is still serviceable.On the other hand I suppose, that Leaky is the spare which was used in the EETCS and was then as a spare on P6. It will now changed for what or ever reason with the spare on ESP-1.The other two PFCS on P6 are in use on Channel 4B and on 2B(from the former EETCS, which was changed in in 2013), so actually no reason for changing.But those are just my assumptions, no source.

Which EMU will Feustel and Arnold wear?
