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.

The Space Coast could welcome a big player to the launch landscape early Sunday with the debut of Blue Origin's New Glenn rocket, a two-day delay from original plans to launch early Friday.

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