What’s the mission: Blue Origin will conduct another test flight this week, as it looks to fly its New Shepard rocket into suborbital space. This time, it will carry a plethora of scientific payloads important to NASA and other research institutions, including a system for measuring rocket fuel in microgravity; another for measuring electromagnetic fields during flight; and a third that will study how dust particles interact in microgravity to glean insight into how planets and other celestial bodies form. Like previous flights, this one will also take up a test dummy into space—Mannequin Skywalker--as a stand-in for future space tourists who might take a ride aboard New Shepard someday soon. The launch, originally set for 9:30 a.m. E.T. Tuesday, was delayed thanks to problems with the ground infrastructure. It seems Blue Origin plans to try again on Dec. 21, but the launch time has yet to be announced.
