How're you feeling about SN9? What exactly had to be addressed to keep the CH4 tank from losing pressure? Any hardware changes or just software? Header tanks are also back pressurized with GCH4 and GOX, right?

SN9 will press CH4 header tank with helium. Long-term solution is under debate. Not clear what is lightest/simplest.
