Is this the first closed loop version? I thought some of the early attempts ran out of hydraulic fluid due to it being open
We used to have a (lame) open loop hydraulic system, but that was upgraded to closed about 2 years ago

Are you running electric pumps to repressurize the working fluid in or something more exotic?

Glad you said 'lame' - I honestly hadn't heard about the transition to closed loop among all the other changes to the F9.

I think running out of hydraulic fluid is why they lost one of the stages. Also why Blue Origin lost their first New Shepard.

Lol how would anyone even consider open loop

Releasing the hydraulic fluid would decrease weight as the flight goes on, but I doubt it made much of a difference.
