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.)

Ponyville, Equestria. Population 5000.

Fallow Meadows, Indiana. Population 8000.

Two towns, two species, two worlds.

But worlds will collide when both are hit by mysterious storms that transport them to a third world unknown to either. Trapped in a place hostile to them both, can human and pony learn to work together? Well, yeah, the story wouldn't be called Unity otherwise.

The real question is what happens when it turns out that they are not alone...

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.
