Has anyone heard anything about what caused the premature relaunch of
SN10. Relaunches are usually after much more than a few minutes or
within a few seconds of landing (for the relaunches of the SN10 type
leading to RUD).

I'm wondering, will this lead to something like don't start servicing a
Starship less than several hours after landing to let the engines cool
down or what not. Or maybe it will lead to keep this valve closed after
landing.

If SpaceX ends up delaying servicing returning vehicles for several
hours, it isn't really a big deal. But still, they seem to want to go
for a very rapid turnaround, so if they could trim those several hours
from the refurbishment time, it can make it even more cool.

I have always wondered. variable temperatures and fuel line
diameters can cause a vapor lock in the fuel system. This is
fairly common in small aircraft engines. But the existence of this
lock does not exclude its application to rocket engines.

This dynamic at liquid O2 temperatures has been tested?
This can result in rocket detonation?
