Publisher’s Note to Launch Solar

— Water is the most important aspect of life on earth. Despite its abundant availability, small percentage be able to use for the purpose of drinking (about 1%). Solar water exoneration comes in the form of a harmless and promising contrivance that purifies water which use a source of renewable solar energy. By rising the collective cause of solar radiation, the competence of solar water exoneration equipment can be increased, which is a mutual outcome of solar radiation, and provides additional heat by solar water preheating system. The main purpose of this effort is to disinfect the water from wastewater using cosmological energy with the course of action of embodiment. This system is proposed to be experimentally created for this purpose.

Havana City

Solar radiation is of utmost importance for life on earth and for carrying out different human and natural activities, such as the studies carried out for agriculture. The objective of this work is to calculate, from formulations, the incidence of solar radiation. Solar energy will be calculated in Havana City, Cuba, during the equinoxes and solstices, as well as the variation that exists during the different seasons of the year. A study was carried out every 3 hours: 6am, 9am, 12m, 3pm and 6pm, (average solar time) creating a table with real values of this energy, obtaining maps of light and shadow planes.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
