Steal the Space Capsule!
Someone has misattributed your dad's heroic astro-deeds to someone else! Steal his old space capsule from the Smithsonian and show the world the truth!
Depending on your stats, choices, or just dumb luck, you may or may not succeed. A lot can go wrong with a plan like that. I mean, "stealing a space capsule from a museum"? Sounds complicated.
(It's not complicated.)
