Blue Origin has been preparing to launch New Glenn for a few weeks now, and finally rolled the 320-foot-tall rocket out to its launchpad at Cape Canaveral, Florida on January 9. At that point, the company was targeting a launch on January 12. But over the weekend, the company pushed that target date back one day in order to increase the odds of successfully landing New Glenn’s booster.
New Glenn’s three-hour launch window began at 1AM ET on January 13. The company loaded propellant into the rocket. But it got stuck troubleshooting the unspecified subsystem issue and pushed the launch time back multiple times before calling it off. (Berger reported that it had to do with ice clogging a line that helps vent gas away from the rocket.)
