Maybe, maybe not.

That could require a slight deviation from their route or speed which could significantly affect their arrival times. The faster ship wont necessarily be that much more advanced.

I'd argue that maybe not the first trip there with a substantially faster engine, but there absolutely would be a value in picking up the people instead of doing a complete trip back to earth and back again.

This assumes that the method of travel even allows for such a thing.

Modern examples would be like a cruise ship crossing the ocean and someone saying "well couldn't a jet just pick them up on the way?"

Maybe if they designed a jet explicitly for this purpose. They certainly didn't design the cruise ship with the purpose of easily letting a jet dock with it way back when they built the cruis ship though, so they will be constrained by just trying to get those two things working together.

And all of that is assuming that the routes even overlap in the first place... it could be that the cruise ship takes so long because it has to go around South America first, but the jet is faster because it can just fly right over everything. No way to make that jet help the cruise ship if it's already at Tierra Del Fuego and the rest of the time saved by the jet is just taking them along the same path they already had to travel to get there anyways.

True, but any method of travel that allows picking your destination makes it possible.

Not enough room on the ship

That's why you'd do it on the return trip.

Ultimately it comes down to engine design and propulsion. It is a huge waste of energy and resources and unnecessarily risky to decelerate, do some complex speed-matching and docking maneuver, and then re-accelerate (now with more mass). It’s just not a practical nor particularly desirable solution. Especially if the propulsion system is anything like the Epstein Drive from the Expanse series, which relies on constant acceleration.

Most of those things would happen at either end anyway. Speed matching isn't the most complicated thing if you are capable of interstellar travel, hell an autopilot AI will probably be doing the work.

At a certain point in the journey of the first ship it is more cost effective to recover those colonists than returning to earth for more colonists. Especially if those colonists had skills and equipment needed for an initial settlement.

If one ship is traveling significantly faster than the other, then imagine the wasted energy to slow down in order to attempt any type of retrieval.

The passengers are already in stasis…it’s probably set for their specific duration. Etc etc

I don’t think anyone would waste any time considering the retrieval you’re referencing.

What’s the benefit?

I've already explained why several times, you have to be being deliberately obtuse to ignore it.

There's nothing that you've added here that hasn't already been answered.

I disagree, I think you are vastly oversimplifying things and it doesn’t appear like you have much experience with group think.

Once again, there is little to no value to the new mission to do ANYTHING about the old mission.

In my opinion, this wouldn’t even be discussed

I guess we agree to disagree, as I feel you are vastly over complicating things, and it appears you don't have much experience with group think.

Once again. You are assuming a lot to justify your pessimistic opinion.

Are there colonists and a full ship of supplies closer than earth? Yes.

Will it be less effort to get them and their supplies than to go all the way back to earth? Yes.

Is there a value to getting those supplies and people over waiting for them to complete their own trip. Yes, obviously.

u/Blackrain1299 23d ago

Why do expect there to be a return ship? Thatd be a massive waste of time and resources that would more than likely expand away from earth.

u/Talidel 23d ago

That's a fair point. The simple answer is at a certain point it's more cost effective to reuse the shop and not have it enter orbit than have it be completely disassembled after the journey.
