This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.

(Sex tag for crude talk about sex, but no actual sex in the story.)

Displeased with her tutelage under the princess of the sun, Sunset Shimmer leaves through a mirror deep within the vaults of Canterlot. With her trusty companion Philomena by her side, Sunset steps into a new world. But not the one the book said it would be. A small calibration error will leave two worlds of magic irrevocably changed.

A crossover with the Harry Potter books and a Sunset in Hogwarts story.
