Here's where SpaceX is going to try and land their rocket for the first time

Elon Musk's rocket company SpaceX is going to try and make history tonight (December 21).

At 8:34 p.m. ET, SpaceX will launch the most powerful version of its Falcon 9 rocket from Cape Canaveral, and then attempt to land part of the rocket back on Earth.

Just a few hours before the launch, SpaceX tweeted out a few images of the landing site, called Landing Zone 1:

Here's what the pad itself looks like. It was repurposed from a structure called Launch Complex 13, according to Universe Today:

And here's where the Cape Canaveral launch facility is.

The rocket will take off from Launch Complex 40, and then (maybe) land back at Landing Zone 1 a few miles away:

If SpaceX pulls off the landing, it'll be able to reuse the rocket for other launches. Reusable rockets could revolutionize spaceflight and significantly reduce the cost of launches.

Here's the livestream, which, Musk says will show both the launch and landing attempt, starting Monday December 21 at 8:30 pm EST:
