Detonation Moon

That's no moon!...oh, wait, yes it was. Oops.

"Mr. President, are you suggesting we blow up the moon?"

"Would you miss it?"

—Austin Powers: The Spy Who Shagged Me

It's bad enough when some bad guy tries to put his John Hancock into the moon, it becomes really serious when it's destroyed. This happens in many continuities in many shows many times. Think of an Earthshattering Kaboom, only on the moon.

A sister trope to Deface of the Moon. Compare with Grasp the Sun for a symbolic use of celestial bodies. Expect there to be No Endor Holocaust.

Something that is only occasionally referenced is that a satellite body does affect the surface of the parent object. Destroying or otherwise removing the moon from it's orbit would cause serious trouble.

Punning on the 1950 SF classic Destination Moon.

Examples of Detonation Moon include:

Advertising

A 7-Up commercial had the spokesman attempt to project the 7-Up logo onto the moon with a laser. Unfortunately, the laser was a little too powerful, and... well, boom.

Orlando Jones: OK! Who had been messing with my laser?!

Anime

Cowboy Bebop has this as a background event, where the destruction of the moon in a gate research accident drove the bulk of humanity to colonize the rest of the Solar System. Earth itself is largely a wasteland now.
- Notably, No Endor Holocaust is largely averted here: The initial shockwave devastated the portion of Earth facing the moon and debris continues to rain down on the damaged landscape. Meteor showers are treated like a weather event by the survivors who live in underground bunkers. The constant creation of new impact craters means any attempt to map the surface is a quixotic venture.
Dragonball Z
- Piccolo destroying the moon to stop Gohan from rampaging as a giant ape (the moon is the giant ape form's power source).
- Dragonball Z Abridged parodies Piccolo's moon destruction via a news report detailing an estimated death toll of over 100 million due to the lack of moon to regulate the tides, not to mention all waterbenders losing their power and Sailor Moon being in horrible agony.
- Master Roshi also blew up the moon in Dragon Ball before it was put back into place some years later. He got yelled at afterwards, but he, like Piccolo only did it to stop a giant monkey attack (it was restored by Kami between those two times on the condition that Goku had his tail removed).
This happens some times in Dr. Slump, it being a gag manga with no realism at all. Usually it's Arale who destroys the Moon with her Super Strength, by chucking boulders at it. Afterwards we see the Moon all patched up, like a broken vase.
In Ouran High School Host Club, this is shown going on inside Tamaki's head in Episode 23 as a metaphor for his Berserk Button of Haruhi being pursued by another guy, the unsuspecting Kasanoda.
A test of the Von Braun's Tandem Mirror engine in Planetes reduced a significant area of the Moon into dust. Judging from the artwork, the damage covered a region larger than the state of California.
Z does this in Tenchi Muyo!, after he destroyed half the earth, for no other purpose than getting Tenchi's attention.
In the manga of Akira, Tetsuo teleports to the moon and blasts a huge hole in it.
In Fairy Tail, a village asks the heroes to destroy the moon, which has turned purple and started turning the villagers into demons at night. Subverted, as they only had to remove the aftermath of a ritual that took place on the island, which made the moon look purple and messed with the memories of the villagers, who really were demons to begin with.
In Star Blazers, the Comet Empire, after defeating Earth's space navy, puts the cherry on its sundae of conquest by destroying the moon.
In Tengen Toppa Gurren Lagann, Anti-Spiral uses the moon to attempt to destroy the earth, causing the Gurren Brigade to attempt to destroy the moon. Notable in that the otherwise VERY soft sci-fi makes it abundantly clear that the approach of the moon and it's removal would have a negative effect on the planet.
Origin: Spirits of the Past uses this trope, though instead of the moon being completely destroyed it's just split into tree.
In Yu-Gi-Oh!, Yugi has one of his monsters stab the moon to destroy it. Yes, it was a moon generated by another card and not the actual moon, but it still has the tide-changing effects...and it wasn't a monster card so he shouldn't have been able to attack it.

Comic Books

The Doctor Who comic strip "The Love Invasion" featured an alien who intended to improve the lives of the human race and his (in the long run) with the first item on his agenda being "destroy the moon". He nearly goes through with it.
The moon of the planet Sakaar (from Planet Hulk) is broken into pieces.
In a What If? story about the Avengers' enemy Korvac, Korvac and the Stranger become involved in a shoving match, with the moon itself as the object being shoved. The moon, behaving at least somewhat according to the laws of physics, gets ripped to shreds by tidal forces and forms a debris ring around the Earth. There is No Endor Holocaust, but it doesn't matter because Korvac ends the universe with the Ultimate Nullifier.
The moon gets destroyed in the "Five Years Later" period of Legion of Super-Heroes. In this case there is an Endor Holocaust, with lunar fragments being a serious threat to Earth for some time afterwards (until Earth got destroyed as well).

Film

This happens in the somewhat distant future in the 2002 film of The Time Machine, when some genius decided that using nuclear weapons to dig caverns beneath the surface was a good idea. It causes a bit of an armageddon. The moon's still there despite their effort, but only about half or so is intact, the rest having settled into orbit or hit the Earth.
The Moon inexplicably combusts in Amazon Women on the Moon, with a small piece continuing to dangle from a wire, after the first astronauts to visit it incur the wrath of the Amazons living there.
Flash Gordon (1980), Ming pokes the moon out of orbit so it is sent on a collision course with Earth.

The novel Die dunkle Seite des Mondes (The Dark Side of the Moon) of the Charity series by Wolfgang Hohlbein ends with the Moon being shattered by a massive hyperspace wave, as a result of something that was done in one of the previous novels in the series. Considering the wave was about to do the same to Earth, the destruction of the Moon is considerably more preferable. One of the characters mentions that humans will have to learn to live without the tides, while another character points out that the tides will still be there, as the main mass of the moon is still in orbit.
In Incarceron, it's mentioned that the Years of Rage have taken their toll on the moon. It still appears to be in orbit, but its innards have been hollowed and its face is pockmarked, effectively killing the tides.
Happens offscreen between the first and second Empire From the Ashes books. Fortunately, it is replaced with a gravity generator to avoid problems with tides.

Live Action TV

From the TV-series version of The Hitchhiker's Guide to the Galaxy, a description of the songs of the rock group Disaster Area: "[They] are, on the whole, very simple and usually follow the familiar theme of boy-being meets girl-being beneath a silvery moon which then explodes for no adequately explored reason."
On The Big Bang Theory The guys are bouncing a laser off the moon to see if it's viewable from Earth and Penny's dim-witted date is worried the moon will blow up. Leonard reassures him that they set the laser to stun.

Videogames

In Sonic Adventure 2, Eggman blows up half of the moon with the Eclipse Cannon to show the world he's not messing around when he announces he's conquering the world. Fans have all sorts of theories why the moon seems none the worse for the wear in all following games, including one where the final battle happens on the surface.
In Skies of Arcadia, the six Moons bombarding the planet with meteors plays an important role in the game's backstory. More ridiculously, there's an Limit Break that allows you to smash one of them into the enemy... naturally, this is ignored once the battle's over.
The end of Kirby's Adventure sees the pink guy fly after Nightmare, eventually ending up on the moon's surface. Before the battle, the moon is whole; after the battle, it becomes permanently crescent, which is retained for every subsequent game in the series.

Almost happens in Avatar: The Last Airbender, when Zhao plots to kill the moon spirit. It's not clear if the moon was physically destroyed/wiped from existence, but at the very least he got it to stop reflecting light. Somewhat averts No Endor Holocaust in that they make it clear the moon's death would be a very bad thing. As it stands, however, all it did was force a Heroic Sacrifice to fix the moon and create one very pissed off ocean spirit kaiju.

Real Life

The rings orbiting the planet Saturn may have formed when a moon orbiting it broke up either by straying too close to its parent planet or was destroyed in a collision with another moon.
Some planets may eventually lose their moons billions of years from now. Because it is orbiting the Red Planet faster than that planet can spin, the Martian moon Phobos may eventually collide with Mars; because it is the largest retrograde object in the Solar System, Triton, the largest moon of Neptune, may eventually also collide with its planet, creating a ring system rivaling Saturn's; and even though the Moon is actually moving away from the Earth until it slows down so much that it it literally stuck above one side of our planet permanently, the dying and expanding Sun will eventually cause the Moon to spiral back toward Earth, causing it to shatter and collide with our own planet (ironically, this was also how our Moon was born).
Project A119. The US during the Cold War had a plan to detonate a nuclear weapon on the moon during the 1950's. Officially called the much less insane-sounding "A Study of Lunar Research Flights".
