Ribbon cutting for Zero-Emission Hydrogen Fuel Cell Bus Program. The principle of a fuel cell was discovered by Christian Friedrich Schönbein in 1838, and the first fuel cell was constructed by Sir William Robert Grove in 1839. The fuel cells made at this time were most similar to today's phosphoric acid fuel cells. [1]
Compressed hydrogen is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology.
In the US Air Force, active duty installations are normally named after notable Air Force personnel, whereas Air Force Reserve and Air National Guard installations are named in the same manner or after the community in which they are located. Because the Space Force is a new service branch, it is defaulting to the current Air Force terminology ...
That has upset some current, part-time Air National Guard members involved in space missions because the proposed move would force them into the full-time, active-duty Space Force. Show comments ...
The Michoud Assembly Facility also houses other organizations such as the National Finance Center operated by the United States Department of Agriculture, the United States Coast Guard, the Chris A. Hadfield Rocket Factory, [34] and GE. [35] [36] The factory complex is open to the public (though through pre-booking in advance).
In 2001, a cooperative effort by NASA's Ames Research Center, Glenn Research Center, and Marshall Space Flight Center (MSFC) was implemented to develop ZBO concepts for in-space cryogenic storage. The main program element was a large-scale, ZBO demonstration using the MSFC multipurpose hydrogen test bed (MHTB) – 18.10 m3 L H 2 tank (about ...
Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts.
The Space Force describes that at a time and place of the United States' choosing it must be able to assure continued use of spacecraft and deny adversaries use of their spacecraft or space-enabled capabilities. [9] Missions that support space superiority include orbital warfare, electromagnetic warfare, and space battle management. [9]
