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.

Celestia has never used her full power.

Ever.

But that might be about to change. Chrysalis has contacted her and requested a meeting out in the middle of nowhere. Celestia expects a trap. In fact, she's hoping for it.

Contains spoilers for Season 7, Episode 10: "A Royal Problem," as it takes place the evening after the events in that episode. The episode itself serves largely as a framing device, however.

Long ago, Luna turned into a twisted, evil version of herself, and Celestia remained to watch over Equestria. Yet Celestia has wondered whether she too could turn into a "Nightmare"... and she's speculated about what she would become.

She has kept these thoughts to herself, but when Celestia and her sister witness the former’s evil counterpart, "Daybreaker," in a nightmare, Luna notes that Celestia does not seem too surprised at her own "dark" side...

The next evening, Luna asks Celestia for her thoughts on Daybreaker - and asks what exactly would turn Celestia into such a monster...

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

When Starlight Glimmer decided to play with time, she created worlds that never should have been. Now she goes to a young Twilight Sparkle, to give her the tools to end the war with Sombra.

She can only hope the Twilight in this world can forgive her for it.

It all started with a simple question. "Can the portal go to other places besides Equestria?

The answer turned out to be "No, but we might be able to make one that can."

When their research is complete, Sunset and Twilight are pulled into an adventure in another world, where they meet even more doppelgängers of themselves. But their alternate counterparts may reveal some things about themselves they never knew.
