I don't think you understand. There are no holes in Voyagers tanks, like
what occurred on Apollo 13. If the tank is filled with gas, or liquid, it
will become a solid. The entire time it is becoming a solid, it will be
producing thrust and moments as it leaves. Solids do not do this, ......
aaahhhh... don't do it nearly as much. Just patch the hole with no
propellant leakage, seriously, what if I am breathing one of the
Propellants?

I thought there were a lot of other good points in the video, like long
term storage in-orbit or on the way to Mars should be as a Solid, not
Liquid or Gas.
Because nobody has ever been able to build leakproof tanks? (Hint: the
Voyagers have been in flight for 43 years and their hydrazine tanks are
still doing just fine.)
Like a cube-sat engine using liquid helium so the hydrogen stays solid.
I would think solid hydrogen encased in boiling liquid helium would be
reasonably safe to take to orbit in a 1U.
vent anything, so forget the boiling LHe. For another, they have to be
able to sit in the rocket for weeks before launch with zero maintenance,
so forget anything cryogenic altogether.
