New Glenn, a massive heavy-payload Blue Origin rocket, had its launch window moved back at least a couple of days.

Blue Origin's massive New Glenn rocket comes in at a towering 320 feet tall — which is equivalent to a 32-story skyscraper. Still, it's overshadowed by SpaceX's Starship, which current launches from Texas and may launch from Kennedy Space Center in the coming years. Starship looms over all rockets throughout history at a whooping 395 feet tall.

Blue Origin put its orbital-class New Glenn rocket through its last major test in preparation for the rocket's first-ever launch.

Beachside spectators have monitored the rocket and Launch Complex 36 pre-launch activities on the horizon for weeks, including a Dec. 27 hot-fire test.

New Glenn will lift off from Launch Complex 36 at Cape Canaveral with Blue Origin’s Blue Ring Pathfinder—a prototype spacecraft designed to host and transport up to 3,000 kilograms of payloads, refuel visiting spacecraft, and enable in-space computing and communications.

The FAA says Jeff Bezos’ space company Blue Origin has “met all safety, environmental and other licensing requirements” to launch its heavy-lift rocket New Glenn.

But with Blue Origin's giant New Glenn soon to join the launch crowd, get ready for some spectacular launch viewing. The Blue Origin launch pad is perfectly poised for a stunning view of the entire liftoff.

A rocket is expected to be launched at a launchpad in Florida that has been inactive for almost two decades. A new rocket about 98 meters long, developed by Blue Origin, is being prepared for the first flight,
