The space agency revealed this event would be happening a couple months ago, as it looks to send the 67-pound lander to drill into the comet's surface, learn more about its composition and, subsequently, send that information back to earth. It's also going to be the first time ever any images are captured from the surface of a comet, so you probably shouldn't miss that.
The ESA expects the landing to take place at around 11:02AM ET tomorrow (November 12th), which means you still have plenty of time to invite friends over for a viewing party, if you're into that sort of thing.
