Ares One was the mission and there is some lore about them.
Nothing major. Hardy is mentioned after the mission, apparently the Traveler made him smart and he kept working on stuff.
One of the astronauts who didn’t land was working on the beginnings of Rasputins AI.
About all I can remember.
People wondered if those three were revived. I doubt it, they were long dead by the time of the Collapse.
It was an:
Astronaut
Cosmonaut
I forget the last one
Rasputin
The Symbol of Destiny is the 3 of them and Rasputin.
There is a Bit of Lore of them..... forgot where though.
