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, targeting an early Monday morning liftoff. The 321-foot-tall rocket making its debut on the NG-1 mission targeted a three-hour window from 10 p.m. to 1 a.m. Pacific Monday for liftoff from Cape Canaveral Space Force Station’s Launch Complex 36.

A successful test flight of Blue Origin’s New Glenn rocket would allow Jeff Bezos’ space venture to compete against Elon Musk’s SpaceX.
