Book Description
The object was to determine if an ultrahigh vacuum facilitated the decomposition of silicates into oxygen and silicon oxide (SiO) or silicon. The practical object was to initiate further research on the possibility of using this oxygen as a lunar resource. An ultrahigh vacuum chamber was constructed capable of obtaining pressures down into the 10 to the -12th power torr range, and simulating the lunar environment. In order to monitor the results of the experiments, a small mass spectrograph was installed on the ultrahigh vacuum test chamber. Tests were run on silicon dioxide, magnesium silicate, and a tektite (an amorphous silicate). All tests indicate that the ultrahigh vacuum significantly lowered the decomposition temperatures of the silicates. In all cases oxygen production was initiated at 1316C. At 1472C the production of oxygen was materially accelerated. The mass spectrograph studied indicates that silicon was produced rather than silicon oxide. In view of the very high pumping speed of the diffusion pump and cryopump on the chamber, it is believed that oxygen production is significant in the 1400 to 1650C range.

Book Description
The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.

Book Description
This book produces convincing evidence that exploiting the potential of space could help solve many environmental and social issues affecting our planet, such as pollution, overcrowding, resource depletion and conflicts, economic inequality, social unrest, economic instability and unemployment. It also touches on the legal problems that will be encountered with the implementation of the new technologies and new laws that will need to be enacted and new organizations that will need to be formed to deal with these changes. This proposition for a space economy is not science fiction, but well within the remit of current or under development technologies. Numerous technologies are described and put together to form a coherent and feasible road map that, if implemented, could lead humankind towards a brighter future.
