Technically, yes, the challenges would be great but not insurmountable. My question is still: why would anyone do this? It would require enormous resources and I don't see any payoff.

If the probes (packed with complex microbes and spores) are small
enough and/or easily protected by a surrounding layer of ice, would be
relatively cheap and otherwise expendables. *Say you sent out a
million of these with some specific target for each of them to
encounter, and if the odds of getting through were only one in a
thousand would still manage seed a thousand prospective targets. *Then
at a much slower and multi-generational trek you eventually catch up
to those targets a few hundred or thousand years later.

Are we still talking about seeding Mars, or an extra-solar planet? Either way, you would still need launch vehicles and a flight vehicle with some means of propulsion, both of which are expensive. And it took around three billion years for life on Earth to develop from single to multicellular life, all you'd have after a few thousand years would be slime.



At least there'd be a good chance of something compatible as having
survived their directed panspermia, existing on those planets. *Or
would you rather land on a new world where nothing was familiar or
compatible?

To be honest, I wouldn't do it that way, no. I wouldn't fire a few shots at a thousand targets because you couldn't fly to all of them. I would pick a very few of the most promising targets and fire at them a lot. Much better odds than hoping the planet you flew to was one of the ones that were successfully seeded. And in fact, I wouldn't even do that. What I would do would be park the ship in orbit and terraform whatever world I arrived at with fully developed species from Earth. It might take a while, but we've already been on the ship a long time, right, so a few more years won't hurt.



If your sun was running out of hydrogen and turning itself into a red
giant, I don't believe there'd be any lack of motivation for getting
the hell away from that nasty thing, especially well before it turned
into a white dwarf.

What would you do if our sun was growing more and more unstable and
getting measurably larger and hotter by the year?

What would you do if there was a Jupiter or Saturn class of rogue/
wandering planet that was for certain headed for impacting your sun,
or your planet?

I am not aware that we are in danger of any of those things happening! And even if they were, "run for it" just isn't an option right now, we don't have anything like the technology to run far enough, or fast enough, or in great enough numbers, and we have no idea where we could run to.

I sense that we have wandered off the point somehow. Oh well.

Your closed mindset is noted, as well as your disregard for all other
intelligent and regular complex life in our solar system, our galaxy
the universe.

Uh, where the hell did that come from? One minute we're discussing hypothetical ways to place life on other worlds, and suddenly this! I haven't mentioned any intelligent life apart from humans, that wasn't even remotely part of the discussion. Why are you going of on a tangent like this?


Are you currently giving God or any other creators the finger?


That would be a very odd thing for me to do, given that I have no belief in such things.
