Blue Origin delays the first launch of its New Glenn rocket for a second time due to concerns about rough seas in the booster landing zone.

You can watch the launch live via Blue Origin beginning at 12 a.m. EST (0500 GMT) if Blue Origin sticks to the opening of its launch window. Space.com will carry the feed as well if possible.

As pointed out by NPR, New Glenn has a similar carrying capacity to SpaceX’s Falcon Heavy rocket, but it stands out with a larger, 23-foot-wide cargo bay. If New Glenn’s launch is successful, it could heat up its rivalry with SpaceX as both companies vie to secure lucrative government contracts.
