Building a Better Hydrogen Trap - Science Daily  Left: Crystalline sheets produced in covalent organic frameworks (COFs) Credit: Adrien Cote. Using building blocks that make up ordinary plastics, but putting them together in a whole new way, University of Michigan researchers have created a class of lightweight, rigid polymers they predict will be useful for storing hydrogen fuel. The trick to making the new materials, called covalent organic frameworks (COFs), was coaxing them to assume predictable crystal structures---something that never had been done with rigid plastics. As a result, the researchers can use X-ray crystallography to determine the structure of each type of COF they create and, using that information, quickly assess its properties. "Once we know the structure and properties, our methodology allows us to go back and modify the COF, making it perform better or tailoring it for different applications," said Cote.   
Raven Industries Announces Five-Hour Flight of 'HiSentinel' Powered Airship - Science Daily  Left:  The 146-foot-long HiSentinel stratospheric airship reached an altitude of 74,000 feet during a technology demonstration flight November 8. The airship is shown fully inflated during preflight verification in a hangar in Roswell, N.M.  The Army Space and Missile Defense Command (ASMDC) sponsored the demonstration. Raven demonstrated a small stratospheric airship with a five-pound payload in 1969. The flight carried a sixty-pound equipment pod to 74,000 feet on a five-hour flight-only the second airship in history to achieve powered flight in the stratosphere. The relatively inexpensive nature of the Hi Sentinel system will allow several test flights per year.   

Spacex Falcon 1 Launch Announced - Science Daily  On Friday, November 25 at 1 p.m. (PDT), the Falcon 1 countdown to launch is expected to reach T-Zero. At that point, the hold-down clamps will release and the Falcon 1 rocket will begin its journey to orbit, accelerating to 17,000 mph (twenty-five times the speed of sound). Designed from the ground up by SpaceX, Falcon 1 is a two stage rocket powered by liquid oxygen and purified, rocket grade kerosene. It will be the first privately developed, liquid fueled rocket to reach orbit and the world's first all new orbital rocket in over a decade. Most importantly, Falcon 1, priced at $6.7 million, will provide the lowest cost per flight to orbit of any launch vehicle in the world
