Boo hoo hoo...

This was the mission that was going to put some dead peoples' cremains on the moon, according to the piece here:

I'm glad they know what happened so we don't have to consider the possibility of telekinesis.

Well, when Russia's lander failed, the comments were full of hate comments that it served them right and they deserved it, forgetting that space travel is incredibly difficult and a single trivial defect can cause a multi million mission to go to waste. Just a reminder.

I realise that the propulsion system is novel in so far that it is intended to operate at low temperatures, hence the use of MON25 oxidser and the new engines. But I assume that the pressurant side of the system is of conventional design.

In past decades there have been concerns about non-return valve and pyrotechnic valve anomalies in bi-prop systems, but I cannot recall the last time I heard of a He pressure regulator failing.
