Blue Origin is counting down to the launch of its New Glenn rocket on an orbital mission that's been more than a decade in the making.

Choppy seas in the Atlantic could still cause a delay, but Blue Origin remains on the clock for an overnight launch of its New Glenn rocket on the Space Coast.

Blue Origin announced that it will launch its first New Glenn rocket from Cape Canaveral in Florida on Sunday. According to a press release from the company, owned by billionaire Amazon founder Jeff Bezos, a three-hour launch window would be opened between 1 a.m. and 4 a.m. ET on Sunday, January 12.
