Sounds like they are predictably trying a fix of SN8's RUD for SN9.
SN8’s test was a huge success, despite the explosive finale. The vehicle successfully conducted numerous first-time milestones, with only the loss of thrust from the re-lit Raptors causing the landing burn to fail and the hard landing.
Mitigation of that landing burn issue, which was blamed on the CH4 Header Tank losing pressure, has been implemented into SN9.
“SN9 will press CH4 header tank with helium,” noted Elon, responding to Tim Dodd on Twitter. “Long-term solution is under debate. Not clear what is lightest/simplest.”
