The new unit histogram concept is described as increasing with one order of magnitude the amount of statistical information extracted from experimental data. The new statistical technology is particularly suited for very scarce population samples, when it dramatically increases the information extracted from the available data. Otherwise, existing features of the population would remain inacces...

Aluminum hydride or alane AlH3 is a very important and fascinating material that has recently attracted attention for its potential for different purposes [1, 2]: (i) as an energetic component in rocket propellants, (ii) as a reducing agent in alkali batteries and (iii) as a possible hydrogen source for low temperature fuel cells. For hydrogen storage, this material will be an excellent candida...

Current research trends have advanced the use of “green propellants” on a wide scale for spacecraft in various space missions; mainly environmental sustainability and safety concerns. Small satellites, particularly micro nanosatellites, evolved from passive planetary-orbiting to being able perform active orbital operations that may require high-thrust impulsive capabilities. Thus, onboard prima...

This paper discusses alternative methods for enabling human explorers to achieve long range mobility on the surface of Mars. Vehicle types considered include ground rovers, winged and lighter-than air atmospheric vehicles, and suborbital ballistic vehicles making use of rocket propulsion. Energy sources considered for such vehicles include batteries, fuel cells, radioisotope generators, solar p...
