Technologies for Space Exploration Describe technologies for space travel: -Multistage rockets * Propelled by the recoil pressure of the burning gases it emits as it burns fuel * Most modern‚ high performance rockets are multistage * Multiple rockets stacked on top of each other that detach separately * Reasons for staging are * To improve performance by eliminating dead weight during flight * A huge‚ empty fuel tank is merely dead weight so it is dropped off

renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with

SPACE EXPLORATION Should governments spend millions on space exploration? Why? How do you see the future of space exploration? Space exploration is about studying the space‚ stars‚ planets and other celestial bodies. Investigation about the physical conditions of all these is carried out in space exploration. This is done through the use of artificial satellites‚ space probes and space craft having human crew. http://www.infoplease.com/encyclopedia/science/space-exploration.html History Humans

Space exploration has been a major interest among the United States since the space race in the mid-1900’s. Though space exploration may seem vital for expanding the wealth of our nation and enhancing life for us earth dwellers‚ there are certain issues that should be taken into consideration such as costs‚ ethical concerns‚ and the safety of our planet before we launch the rockets. Exploring the solar system is positively viewed by many‚ but most people do not agree with the amount of money

Debra Stadelman Mr. Willard Science and tech. 4th quarter project SPACE EXPLORATION Space exploration has been very important in human life. The first object in space was Sputnik 1 and it was launched by the U.S.S.R.in 1957. When sputnik was first launched it seemed as if it were to start a new war against the United States. But as the studied it more they realized that it was just a satellite circling the globe. That it meant us no harm. In 1958‚ launched by

Lori Mares 03/07/13 Exploration in Space Space exploration has been around for a long time ever since the first rocket went into space. That was the work of the Germans after world war II. The competition to be the first in space began in 1945 and would last 30 years. The Space Race pitted the United States and Soviet Union against each other in a contest that extended from the Earth to the surface of the moon and beyond. Humans have dreamt of exploring space for a very long time. Centuries

Exploring space is a waste of money? Space exploration has been a huge part of our history; from Neil Armstrong and Buzz Aldrin winning the “space race” withRussia‚ to the Mars Rovers. There are many different takes on the matter of space exploration and a lot of people feel that the disavantages far out weigh the benefits. Yet‚ many others believe that space exploration should be continued at all costs and that it has proven to be very beneficial in the past and will continue . To start off

Space Exploration Is space exploration a waste of resources or a useful contribution to society? I am here to present to you my views on this topic. Firstly‚ I would like to start off by saying that I believe space exploration can really be a waste of time and money. Though some of the discoveries might be interesting to us on Earth‚ I fail to see why people and companies (like NASA) spend so much money on things that don’t help us very much when there are people dying every second due to hunger
