was a part of NASA’s ERAST programme (Environmental Research Aircraft and Sensor Technology). It was developed by NASA and Californian company AeroVironment Inc. ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in the future such aircrafts could

astronauts when an amount of radiation gets through the walls of a space shuttle or station and enters the body. Solar radiation usually affects astronauts walking in space‚ outside of their space shuttles‚ but sometimes it can even affect the people on Earth‚ causing electricity failures. Many people - astronauts mostly- fear the consequences of solar radiation‚ due to the fact that solar radiation can cause dangerous effects to one’s health. Even though sometimes the effects are so minor‚ you can

Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

The Benefits of Solar Energy Melissa Strayer University English 215 July 20‚ 2012 The Benefits of Solar Energy Solar energy represents the future of a clean earth in days to come; it also represents the clean air that our children and their children will breathe. We constantly have to worry about pollutants in our air from all of the many harmful chemicals being thrown into the air by fossil fuels; we never stop to think about how this will affect our children‚ and it’s time that we start

Solar Power In India India’s power sector has a total installed capacity of approximately 1‚46‚753 Megawatt (MW) of which 54% is coal-based‚ 25% hydro‚ 8% is renewables and the balance is the gas and nuclear-based. Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements and are likely to increase in the coming years. In the next 10 years‚ another 10‚000 MW of capacity and investment of about Rs. 24 lakh crore are required. Fortunately‚ India lies in sunny

Solar System For Households As the development of technology is flourishing‚ fossil fuels are unceasingly depleted for enormous generation of energy. With limited resources‚ alternative forms of renewable energy are emerging. Among them‚ solar power has been growing at a blistering pace in recent years. It sparks controversy among different parties. Some people applaud this method saying it is more environmentally friendly; while some others express resentment on the astronomical cost of building

Proper understanding of each of these discoveries and theories is important when learning about our universe. Planetary Accretion Planetary accretion has two main theories on how the planets in our solar system were formed. The first of the two is the Solar Nebular Disk Model; this is where our Solar System’s planets started out as small pieces and started to collide together‚ uniting into bigger pieces and this kept happening until they became planetesimals. Once they were planetesimals‚ they crashed

Aleksander Tucker 21 April 2013 ECS 310 Wind and Solar Power Wind and solar power are the future. They are clean‚ renewable‚ and infinite sources of energy and allow for energy to be produced domestically. They are also complimentary; Wind and solar energy will also be economically beneficial. Maintenance is easy‚ and long-term cost is a great advantage. Wind turbines and solar panels can also be very aesthetically attractive‚ and people can comfortably live around them. Human health risk is

Solar Panel The world’s energy demands increase year after year‚ while its resources are consistently being depleted in order to sustain these energy demands. These limited resources will one day be no more. A dependable source of renewable energy must be found. Currently solar energy is not efficient enough to sustain the population. However‚ the technology is constantly advancing‚ and solar energy could one day be that source. The solar cell’s roots can be traced all the way back
