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.

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

Rough weather has prompted Blue Origin to postpone the launch of its New Glenn rocket, citing choppy waters in the Atlantic Ocean, and creating potentially unsafe landing conditions for its reusable fuel booster.
