You're just an ordinary guy, living an ordinary life. But your life changes one miserable Monday, when you arrive home to find an unexpected visitor in your house: specifically, you discover Twilight Sparkle in your bed.

Things go downhill fast.

And she's just your first visitor.

Tags and contributing authors will be added as needed. A couple new chapters will be added daily until the well runs dry. Continuity is overrated, so don't complain about it. It's a thematic collab, not a big budget Hollywood movie where there are never any continuity errors.

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.
