Blue Origin is counting down to the launch of its New Glenn rocket on an orbital mission that's been more than a decade in the making.

Blue Origin pushed again its planned debut launch of its New Glenn rocket from the Space Coast, now targeting an early Monday morning liftoff. The 321-foot-tall rocket making its debut on the NG-1 mission is targeting a three-hour window from 1-4 a.

You can watch the launch live via Blue Origin beginning at 12 a.m. EST (0500 GMT) if Blue Origin sticks to the opening of its launch window. Space.com will carry the feed as well if possible.
