... had a political impact for both Jimmy Carter and NASA. The scope of this article reviews internal memos and author interviews along with secondary sources and contemporary events to show the involvement of NASA, Administration personal and the President working together to solve this ...

... an explosive wrapped with lunar regolith or lunar water is tractable only through numerical simulations, and only on a case-by-case basis. Qualitatively, regolith has a shorter mean free path ... . Water represents the opposite properties, a smaller ionization energy and a longer radiation mean free path. Using these qualitative properties, the applications and performance of the two propellants are compared. '''To BUY ...

... of commercial satellites. Current industry estimates indicate that 70% of the satellites launched between 1999 and 2008 will be commercial. Commercial satellite operators would like to use COTS, including Plastic Encapsulated Microcircuits (PEMS) for reasons of high performance, low cost and good availability. However, COTS components are not designed for use in the space radiation environment ...

... are obliged to operate within the space radiation environment. The resultant background noise is high and derived from extremely complex sequences of particle interactions. In order to improve the sensitivity of ... , it is vital to understand the detailed contributions to the background noise in meticulous detail and devise methods of suppressing them. These aspects are discussed in this paper. '''To BUY this ...

... During 1984-1991 China launched a series of small communications satellites in the DFH-2 and DFH-2A series. This paper will review the programme, discussing the in-orbit behaviour of ...

... these objects can be expected to have a mass at and below the deuterium fusion limiting mass of ~13MJup and hence can be classified as planets. The number of ... low-mass objects has a number of interesting consequences for the physical structure, number distribution and dynamics of small objects in the Galaxy. One or more interstellar planets should lie significantly ... of a light year. ISPs may be also of great significance both for the existence and widespread presence of life in the universe. They may also provide stepping stones for the ...

... Pages''' - 9 Abstract This article is concerned with the early relationship between Wernher von Braun and the British Interplanetary Society (BIS). The BIS/Wernher von Braun/Val Cleaver correspondence files located ... & Rocket Center in Huntsville, Alabama are unparalleled. As one reads the stimulating comments between Cleaver and von Braun, the need to share their thoughts prevails. Following is an excerpt from one ...

... of Pages''' - 12 Abstract The initial model showed a large deviation with the given performances and therefore some more detailed analyses were conducted. These included residual propellant mass estimates, hydrogen peroxide flow in the first stage, jet vane influence on the specific impulse and a fairing mass analysis. With the results a final model was constructed whose accuracy was ...
