Nuclear Ferry and Shuttle Orbiter docked to an Orbital Propellant Depot. The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), [1] was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program (NASA appropriated the name for its Space Shuttle Program, the only component of ...
Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of ...
The Critical Care Air Transport Team (CCATT) concept dates from 1988, when Col. P.K. Carlton and Maj. J. Chris Farmer originated the development of this program while stationed at U.S. Air Force Hospital Scott, Scott Air Force Base, Illinois. [1] Dr. Carlton was the Hospital Commander, and Dr. Farmer was a staff intensivist.
A Safeguards Transporter (SGT) is a truck developed for and used by the National Nuclear Security Administration (NNSA), a semi-autonomous affiliate agency of the United States Department of Energy, for the ground transport of nuclear weapons in the contiguous United States. SGTs' trailers are known as Safe Secure Trailers (SST).
Containers, also known as intermodal containers or ISO containers because the dimensions have been defined by ISO, are the main type of equipment used in intermodal transport, particularly when one of the modes of transportation is by ship. Containers are 8-foot (2.4 m) wide by 8-foot (2.4 m) or 9-foot-6-inch (2.90 m) high.
