Jeff Bezos' Blue Origin is set for an inaugural launch of its giant New Glenn rocket on Sunday, a long-awaited first leap to Earth orbit that sets up one of the biggest challenges yet to industry dominance enjoyed by Elon Musk's SpaceX.

Blue Origin says it's delaying the first launch of its New Glenn rocket due to unfavorable weather conditions for landing the booster.

Blue Origin plans to launch the debut mission of its powerful New Glenn rocket no earlier than early Sunday (Jan. 12) after a delay, and you can watch the action live. New Glenn is scheduled to lift off from Florida's Cape Canaveral Space Force Station in the wee hours of Sunday during a three-hour window that opens at 1 a.m. EST (0600 GMT).
