During the attempt, the Jeff Bezos-owned space company aims to reach orbit, helping to further its goals of shuttling Project Kuiper satellites, equipment, and eventually humans into space. Here’s what you need to know about when and how to watch New Glenn’s long-awaited inaugural launch. What is New Glenn? New Glenn is the 320-foot-tall rocket that Blue Origin initially announced in 2016. Though Blue Origin planned to launch New Glenn by 2020, the project was beset by delays due to issues with engine development and other technical setbacks. The rocket has a reusable first stage powered by the company’s BE-4 engines, which run on liquified natural gas and liquid oxygen. Shortly after launch, the first stage is supposed to detach and autonomously land upright on a sea-based platform, where Blue Origin can then retrieve it and reuse it for future missions. Following separation, New Glenn’s upper stage should fire up its BE-3U engines — a less powerful engine that uses liquid oxygen and liquid hydrogen — as it attempts to propel itself into space with its payload. The upper stage is capable of delivering 45 metric tons of cargo into low Earth orbit. For this uncrewed launch, New Glenn will house the Blue Ring Pathfinder, a payload consisting of a communications array, a power system, and a flight computer. This will let Blue Origin test its Blue Ring spacecraft, which will eventually support missions with refueling, hosting, data relay, and cloud computing capabilities.

Earlier this week, Blue Origin scrubbed New Glenn’s launch due to a “vehicle subsystem issue.” A successful first launch could make Blue Origin a serious rival to Elon Musk’s SpaceX. Along with competing for government contracts, both commercial space companies are also working to build out internet satellite constellations, with SpaceX regularly sending Starlink satellites into space and Blue Origin on tap to support Amazon’s Project Kuiper initiative. When will Blue Origin launch New Glenn? Blue Origin’s next launch attempt will take place at Launch Complex 36 in Cape Canaveral, Florida, on Thursday, January 16th. The three-hour launch window opens at 1AM ET (10PM PT). Blue Origin says the “vehicle looks good” for Thursday’s launch window, but says it’s “watching weather closely as clouds build over the Space Coast.” If the company can’t attempt to launch New Glenn on the 16th, it will make another attempt Friday, January 17th with a three-hour window opening at 1AM. How to watch New Glenn’s launch You can watch a livestream of New Glenn’s launch from Blue Origin’s website, its X account, and its YouTube channel. We’ll embed a livestream here when it becomes available. Update, January 15th: Added an update from Blue Origin about launch timing.
