I imagine that if we could transform the Moon into a beautiful planetary ring around Earth, wouldn't it be spectacular! Problem is the feasibility. Are there any practical solution?

Option

I think blowing up the Moon is the only viable option but wouldn't it also spell disaster for Earth, too? With all the debris from the leftover of the Moon they will eventually form a ring around Earth will they?

Objective

Transform Earth to look like Saturn. I couldn't care less about the Moon as long as it does not obstruct the planetary ring.

  • $\begingroup$ Actually; there's already a theory that, without some serious orbital cleanup proceedures, we'll eventually end up with a ringed Earth without touching the moon simply due to orbital trash from rockets and satellites piling up! This will naturally be quite a thin ring, though, not a Saturn-esq ring. $\endgroup$ – eharper256 Apr 21 '15 at 8:27

  • $\begingroup$ This will likely render huge swaths of the Earth uninhabitable to humans as the Sun's gravity will take the place of the moon. $\endgroup$ – JDSweetBeat Apr 21 '15 at 13:05

No need to blow it up, just give it a gentle push to the edge of earths Roche Limit. The gravitational pull will slowly tear it apart and create an awesome ring. I've grown tired of the moon anyway, so I endorse this plan. Risk of huge chunks of the moon crashing into the earth is a minor concern.

This article covers your question quite well

Blowing up the Moon would create quite enough debris on orbits steep enough to fall on Earth and end all life. Leave our Moon alone.

Let's develop a good, strong drive and fetch a plenty of small asteroids into Earth orbit, somewhere between LEO and GEO because the satellites are very useful.

Crash them into each other gently, to break them apart into multiple meteorite-sized chunks, without spreading them by much. There, you have your ring.

Alternatively, decelerate the Moon gradually, until tidal forces are strong enough to overcome its gravity, tear it apart and let it form a ring.

Easy mode: Get the Chinese to launch four-five more of their anti-satellite rockets. (yes, even 2 should suffice; we're close enough for that!) This should increase the amount of space junk past the chain reaction threshold, as satellites hit by space junk explode into more space junk, very quickly turning the Earth LEO into a massive, shiny cloud of debris, and preventing all space travel for a next century or so.
