The Reverse Fate of the Challenger

The loss of the space shuttle Challenger in 1986 was felt across the world.
Across the whole Universe.
On Jupiter, they felt it so keenly that the King and Queen reverse-engineered the solar system back trillions of years, micro-adjusting the orbits of their moons.
However, their plan hinges on a young black woman in mid-twentieth century America.
They must send down an alien task force to ensure her future, for that future involves the Challenger.
And the doom of all worlds rests on changing the destiny of that ill-fated vehicle.
