This is the space version of the Jamestown Settlement, a suicide mission. Always must be a return-to-Earth strategy. Jamestown failed, but Plymouth succeeded (barely) because the “mother ship,” the Mayflower, stood offshore and provided shelter & provisions through the winter for the Pilgrims. It also provided a return-to-England capability, plus multiple & continuing return trips by other vessels. A one-shot “fly and die” program is foolish and stupid. Humankind must be better than this.
I think this is more like Roanoke.
