My attempt at a more serious 'Luna meets Neil Armstrong' storyline. What would really happen, both on the moon and on Earth? Inspired by 'The Eagle has Landed' by CyanBlackStone.

Princess Luna has found herself on a very different moon after some strange force interfered with her banishment. She doesn't know what the metal objects that keep orbiting and sometimes landing there are, but she wants to find out. Meanwhile, Neil Armstrong believes that being the first man on the moon will be the crowning achievement of his life. Hoo boy, is he ever in for a surprise.

For those who are interested, the most excellent Zanec has provided this link to an interactive Apollo 11 site.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

Plowpony's Day- a day of peaceful rest and relaxation. Or it was, until Twilight Sparkle badly mangled a teleportation spell. It has left her with a bad case of Horn Rot, a disease that if untreated could prove fatal. What's more, the malady is advancing faster than the slow-brewing potion that cures it!

There is one swifter cure: the Beneviolet, a star-shaped flower that grows in the distant Archback Mountains, far beyond the western borders of Equestria. Applejack, Rainbow Dash, and Rarity choose to undertake the long journey for the sake of their friend. Their path will wind through floes of ice, across gold-tinted plains, into distant forests glimmering with magic. They will learn much about the world beyond their homeland- and much about themselves, as well.

Yes, it's "Dangerous Business," here on FIMFiction. A huge debt is owed to all those who have supported me over the years. I've edited the story some to remove extraneous bolding and italics, but other than that, it remains unchanged. I hope new readers enjoy it as much as old ones did.

Twilight has been having her study sessions with the Cutie Mark Crusaders for some time, and has been remarkably pleased with their progress. And kind of worried, as they keep getting better and better. She might be a princess now, but TEACHING THE CUTIE MARK CRUSADERS? She'd rather not become their formal mentor. Yet.

A letter is sent out, and Princess Celestia gets a call for help. And, an opportunity is born. After all, why not? After a thousand years, perhaps it is time to do something else, just for a bit. She does have a rather wonderful younger sister who hasn't been ruling a land for a thousand years, and who has been studying how to rule for the past four rather intensely. So, teaching three fillies undercover? Sounds like fun.

And Luna. She's wanted to be as respected as her sister so much that she once went mad over it. But now, she's simply being handed the power that she once coveted for so long and no longer wants. What kind of a world does she live in now that her highest desire has been so casually granted?

With all of this, What Could Possibly Go Wrong?

Arcs:

Escape: When Celestia hears the call, she jumps at the chance to teach again, especially three fillies who might surpass her grandest student. But first she's got to escape her own identity...
Examination: So you want to find out what a filly does? Time to test her silly, so long as you don't taunt the Happy-Fun Filly.
Excitement: So, you've found the Happy-Fun Filly. Great, but the other two need help as well, and Scootaloo has this ~Great!~ idea for how to use her new-found magic...
Encouragement: Cometh the Bubbles, and a whole load of new headaches as they find out just what being a Happy-Fun Filly really means...
Exaltation: Where's Luna been this whole time? She can't be very happy about being left in the lurch holding Equestria. She could really use somepony to talk to.
Exercise: 'Sunbeam' is looking to teach the Happy-Fun Filly more, but first she needs to start taking care of the wagon-tire she keeps around her middle so that certain Unfun-Time Fillies don't interrupt her. And there's this big draft stallion looking for help...

Smaug is the mightiest of all beasts in Middle Earth. No creature can match his prowess. As the last of his kind, he has no obligations to anyone being other than himself. The only thing he cares about is his hoard.

But this new creature, this alicorn, may just change that.

Cheerilee knows two things: she's an earth pony and she loves being a teacher at Ponyville Elementary. Nevermind the fact her mother was a pegasus and both her father and older brother are unicorns, the latter of whom just got married to an earth pony with a better teaching job than Cheerilee. It doesn't bother her, because she just loves being unable to find a higher paying job than what she has now. Really. She isn't that serious when she absentmindedly wonders if being a unicorn would improve her job prospects.

So with all that in mind, she isn't happy at all when she wakes up to discover she has spontaneously turned into a pegasus, a change that goes far deeper than just sticking wings on her back. And the trials she has to go through as a result of her new status will make her call into question just who she is and what she really wants out of life.

After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.

Wake up. Go to work. Save Ponyville from unimaginable horrors beyond time and space. Have lunch with your PFF.

Ditzy Doo lives in a different world than her fellow ponies. She sees things nopony else can see—like higher-dimensional spatial anomalies, fae creatures, and eldritch abominations. And she uses what she sees to solve problems that nopony else even knows about.

But this time, Ditzy may have bitten off more than she can chew. Something very unfriendly is trying to enter Equestria through Ponyville’s Town Hall. An earth pony with an hourglass cutie mark has taken an unhelpful interest in Ditzy. The Princess’s personal student has grown suspicious. And, most irritating of all, her alarm clock radio is acting strangely.

Ditzy must race against the clock to save Ponyville—a clock that keeps playing the same song over, and over, and over ...

Over a thousand years ago, two royal siblings fought for the sky and were exiled, one by her sister's hoof, and one in penance for what she had done.

In the present Republic of Equestria, no one remembers them as anything more than legends and old pony tales. Save for one shy filly who fell from the sky one fine summer's day.

An Alternate Universe "What If" tale, reconstructing the beginning from a different angle.
