Blue Origin is once again counting down to the first launch of its orbital-class New Glenn rocket, buoyed by a better weather forecast.

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.

Blue Origin is planning to launch its reusable heavy-lift New Glenn rocket for its inaugural voyage at 1 a.m. EST Sunday if weather conditions allow it to proceed.
