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.)

After strange occurrences with radios across the world Twilight does some research. What she finds, changes everything.

Anon likes his life to be simple. He wakes up, goes to work and sometimes gets himself a good book to read while he is home. It's a routine that he likes to follow, it makes him feel like he has a bit of normality with his life in Equestria. The fact that having Celestia come crashing into his home as part of his routine should prove that his life is anything but normal.

(Thanks to PeerImagination for editing!)

A not so standard human-in-Equestria story including but not limited to: democracy, tequila, and robots.

Things escalate from there.
