The difference being that they had a hope of returning in the "Age of Exploration".
Often, they didn't know that, and the changes of not returning home were >50%
One way trips have no hope of returning.
The likelyhood of this is also greater than 50%, but less than 100%. Who knows what discoveries could be made off-planet?
That said, not everyone who "didn't return home" in the colonization days died, some settled despite the harsh environment. This would be more the intent of such a mission off-planet. It's being portrayed as a death sentence, when really it's more of a chance to be part of early colonization attempts.
