About Space
Some of the most frequently asked questions about the U.S. space program are "Why go into space when we have so many problems here on Earth?" and "What does the space program do for me?" These are legitimate questions and unfortunately not enough people have been made aware of the vast benefits the space program provides that increase the quality of our daily lives. Applications on Earth of technology needed for space flight have produced thousands of "spinoffs" that contribute to improving national security, the economy, productivity and lifestyle. It is almost impossible to find an area of everyday life that has not been improved by these spinoffs. Collectively, these secondary applications represent a substantial return on the national investment in aerospace research. We should be spending more.
Out of a $2.4 trillion budget, less than 0.8% is spent on the entire space program! That's less than 1 penny for every dollar spent. The average American spends more of their budget on their cable bill, eating out or entertainment than this yet the benefits of space flight are remarkable. It has been conservatively estimated by U.S. space experts that for every dollar the U.S. spends on R and D in the space program, it receives $7 back in the form of corporate and personal income taxes from increased jobs and economic growth. Besides the obvious jobs created in the aerospace industry, thousands more are created by many other companies applying NASA technology in nonspace related areas that affect us daily. One cannot even begin to place a dollar value on the lives saved and improved lifestyles of the less fortunate. Space technology benefits everyone and a rising technological tide does raise all boats.
One small example is the Hubble Space Telescope. Much maligned at first because of its flawed optics, it still produced better photographs than anything here on Earth. Once fixed, it has produced even more startling scientific data which we have only begun to understand and apply. One of the many spinoffs from the Hubble telescope is the use of its Charge Coupled Device (CCD) chips for digital imaging breast biopsies. The resulting device images breast tissue more clearly and efficiently than other existing technologies. The CCD chips are so advanced that they can detect the minute differences between a malignant or benign tumor without the need for a surgical biopsy. This saves the patient weeks of recovery time and the cost for this procedure is hundreds of dollars vs. thousands for a surgical biopsy. With over 500,000 women needing biopsies a year the economic benefit, per year, is tremendous and it greatly reduces the pain, scarring, radiation exposure, time, and money associated with surgical biopsies.
Below is a "small" sampling of the many other ways that space technology has improved our lives and benefited mankind. It is truly a remarkable list and not nearly complete but I believe you will begin to appreciate the answers to "Why do we go in space" and "What does the space program do for me?" So the next time you hear these questions being asked, you will be able to explain it.

World's First Commercial Space Station Planned in Russia
Two Russian aerospace companies are teaming up to build what they say will be the "world's first commercial space station" – an orbiting outpost open to private citizens, professional astronauts and scientists. For a price.
Called the Commercial Space Station, the orbiting space laboratory and hotel will be able to host up to seven people at a time. It is being planned under a partnership between the Russian companies Orbital Technologies and RSC Energia. [Illustration: Russia's Commercial Space Station]
The companies announced plans for the new space station today (Sept. 29) but did not reveal an estimated cost. The space station is expected to launch sometime between 2015 and 2016. The cost of individual trips may vary based on launch vehicle, duration and purpose of missions.
"Once launched and operational, the CSS will provide a unique destination for commercial, state and private spaceflight exploration missions," said Orbital Technologies chief executive Sergey Kostenko in a statement. "The CSS will be a valuable addition to the global base of orbital assets."
Space hotel and orbiting lab
Medical experiments and Earth observations are just some of the services the space station is expected to offer. Space tourism, Kostenko said, is another big field.
"We also have proposals for the implementation of media projects," he added. "And, of course, some parties are interested in short-duration stays on the station for enjoyment."
Moscow-based Orbital Technologies is a company of engineers, scientists and space industry veterans dedicated to opening space for private enterprise, according to its website.
RSC Energia is the largest contractor serving Russia's Federal Space Agency and has extensive experience building space station modules and spacecraft. The company built Russia's Salyut space stations, the multi-module Mir Space Station and major Russian elements of the International Space Station. RSC Energia also builds the Soyuz and Progress spacecraft that launch routinely to the International Space Station.
Vitaly Lopota, president of RSC Energia, said the company has 40 years of experience building space stations and has been outlining plans for the Commercial Space Station for more than 10 years.
The new space station would have an initial design life of about 15 years, Orbital Technologies officials have said. Soyuz spacecraft would ferry crews to the station, while unmanned Progress vehicles would keep it stocked with supplies.
The station will also fly in an orbit about 62 miles (100 km) from the International Space Station and in a similar inclination, or tilt, to make any transfers of crew or cargo between to two stations easier, the company said.
The company's description of the station do not specify its power systems, however a spokesperson told SPACE.com the initial module would have systems similar to the Zvezda service module on the International Space Station. The Russian Zvezda service module is equipped with solar arrays and thrusters for attitude control.
The Russian announcement comes amid a major push for commercial space vehicles and rockets in the United States, where at least one company – the Las Vegas-based Bigelow Aerospace – is planning commercial space stations of its own.
Bigelow Aerospace has already put two prototype space station modules in space, called Genesis 1 and Genesis 2. The modules are inflatable craft that launched in 2006 and 2007 and both remain in orbit.
The company is aiming to have a full-scale private space station in orbit and ready to receive customers by 2015, according to past reports. If so, Bigelow Aerospace's inflatable space station modules would snag the title of the world's first commercial space station in orbit if it launches before Russia's Commercial Space Station.
Another company, Excalibur Almaz in the Isle of Man, is planning to use spacecraft originally designed for the Soviet-era Almaz space stations to offer weeklong orbital spaceflights for paying customers.
The U.S. push for privately built spacecraft comes as NASA plans to use commercial space vehicles to ferry astronauts to the International Space Station once the agency's space shuttle fleet retires in 2011.
Russian space agency takes notice
The Commercial Space Station plan has also sparked interest in Russia's Federal Space Agency.
"We consider the Commercial Space Station a very interesting project, encouraging private participation," said Vitaly Davydov, deputy chief of the Federal Space Agency. "It will attract private investment for the Russian space industry."
The Russian space agency's chief, Alexey Krasnov, added that a commercial space station could serve as a backup for International Space Station crews.
"For example, if a required maintenance procedure or a real emergency were to occur, without the return of the ISS crew to Earth, habitants could use the CSS as a safe haven," Krasnov said.
As planned, the Commercial Space Station would use a universal docking system that could accommodate spacecraft from Russia, the United States and Europe, Orbital Technologies officials said. The station also is expected to accommodate China's Shenzhou space capsules, which have flown three manned missions since 2003.
The space station could serve as a springboard for even more ambitious voyages into deep space, Kostenko said.
"A short stopover at our station will be the perfect beginning of a manned circumlunar flight," he added. "Deep-space manned exploration missions planned in the next decade are also welcome to use the CSS as a waypoint and a supply station."

From NASA/JSC Office of Public Affairs:
Do you feel like an astronaut when you go to the grocery store? How about when you set your watch?
The next time you reset the smoke detector in your home, take a minute to imagine it as part of your own spacecraft's caution and warning system. Because before they saved lives on Earth, that's where smoke detectors were found on spacecraft designed and built by NASA.
Although NASA's most visible achievements have taken place in space, the technologies that put men on the moon, launched space shuttles and will build a space station have found their way into everyday life on Earth.
These common secondary uses, called space spinoffs, have continuously enhanced the lifestyle of Americans and strengthened the U.S. economy since the 1950s.
The technologies that led to the computer bar codes in retail stores, quartz timing crystals and household smoke detectors were originally developed for NASA.
NASA technology has provided many benefits to the medical field. The pacemakers used to treat cardiac patients as well as the remote monitoring devices for intensive care patients were derived from the telemetry systems that first monitored astronauts and spacecraft. Much of the portable medical equipment carried aboard ambulances has its roots in NASA's needs for such portable equipment in space.
These are but a few of the more than 30,000 secondary applications of space technology providing daily benefits in Earth-bound hospitals, offices and homes.
In the past, such spinoffs often happened by chance a coincidence when practical uses of new technologies were found.
NASA is now seeking to make the spinoff a part of the product itself.
Working jointly with private industry to develop technologies that have a use in space and on Earth lessens the cost of development for NASA, and, ultimately, the taxpayer.
Technologies developed for NASA to meet the challenges of space exploration have found more than 30,000 secondary commercial uses in products ranging from tennis shoes to medical equipment, bar codes, pacemakers and sunglasses.
Fabrics
NASA's use of aluminized materials to serve as insulation for satellites and spacecraft helped lead to a revolution in reflective insulating materials ranging from survival blankets to wraps for water heaters to new types of interior home insulation. Extremely strong fire-retarding materials that were developed for use in the pure-oxygen air of early spacecraft have led to a host of cloths, such as Beta Glass, used in fireproof clothing, accessories and firefighter's suits. Other spacecraft materials have included teflon-coated fibers with extremely light weight but great strength that have been used as roofing material for such structures as the Detroit Silverdome and the Jedda, Saudi Arabia, Airport.
Materials
Composite materials, a mix of fibers and resins designed to provide great strength yet remain very light weight, have been synonymous with all aerospace applications from airplanes to NASA spacecraft and have advanced into lightweight, strong materials for helmets, tennis rackets and other sporting goods. NASA spawned further development of memory metals, metals that remember their former shape when bent, in its early space station studies and advanced forms of the materials are now used in common flexible metal eyeglass frames. Other glasses benefit from scratch-resistant coatings originally developed as a protective coating for delicate spacecraft parts. In footwear, a shock-absorbing spacerÓ technique originally developed for the boots of moonwalking astronauts has given birth to an entire new family of shock-absorbing tennis shoes and other athletic shoes.
Electronics
The smoke detectors now required by law to be placed in all homes and universally credited with saving countless lives are an end result of a technology originally developed for NASA's early 1970s Skylab spacecraft. Quartz timing crystals which have led to the current status quo in wristwatches and small clocks were first developed for NASA as a highly accurate, lightweight and durable timing device for the lunar-bound Apollo spacecraft. On the moon, astronauts used specially developed portable, battery-powered electric tools to drill into the surface and take samples of the crust, tools that were the direct predecessor of today's cordless screwdrivers, drills and other rechargeable power tools. Common bar codes now used for pricing in supermarkets are an advancement of technology originally developed for uses within NASA, such as maintaining a highly accurate inventory of millions of spacecraft parts. Bioreactor
A cell culture device developed as part of space medicine research at JSC may allow scientists to better test new treatments for cancer and viruses without risking harm to patients. The rotating wall bioreactor, a cell culture device that was developed as part of space medicine research at JSC, mimics the effect weightlessness may have on cell cultures by incorporating a rotating cylinder to hold the culture. With its rotation, pressure points on the growing cells are relieved and the device can grow three-dimensional, highly accurate tissues, unlike previous culture growths which grew in two dimensions. Already being commercialized by a small company in Houston, the device has been used to grow more than 35 cell types and no cell type yet tested has not grown well in the system. The bioreactor may add a valuable new tool to the arsenal of medical research.
Zeolite Soil
The study of how to grow plants in the most inhospitable location yet visited by humans the moon led to the development of a synthetic soil by JSC researchers that holds promise as a revolutionary fertilizer and soil on Earth. The zeolite soil mix takes advantage of the natural properties of a common mineral called zeolite in storing and time-releasing nutrients. A JSC-developed additive is mixed with the specially prepared zeolite to create a soil that in laboratory testing has produced conditions almost comparable to the fertility provided by hydroponics, a well-known technology that uses water to provide plants with a precise nutrient mixture. However, unlike hydroponics, the zeolite soil does not require massive pumps and pipes. The zeolite mixture already is being commercialized by two U.S. companies and may provide a valuable new fertilizer that, due to its time-release properties, avoids runoff pollution, a common symptom of current agricultural fertilizers, as well as providing high fertility.
Implantable Heart Pump
NASA's expertise in tiny yet highly reliable pumps may provide an alternative to the large, external heart pumps used by patients awaiting a heart transplant. JSC has combined forces with the Baylor College of Medicine and famed heart surgeon Dr. Michael Debakey to make use of the center's expertise in developing the Ventricular Assist Device. The new generation of heart pump already is undergoing implant tests in animals and, if they continue to go well, a first human implant may come soon. The pump would allow critical heart patients a much more convenient alternative to the heart pumps currently in use.
How does modern technology help our daily life?
Technology has changed the life of the people around the world. It is something that keeps on improving which takes over some jobs that human used to do and change the way of how things gets done. And blessing is a feeling which makes someone feels happy because something happened in their lives.

Technology, for example; office application, accounting program and internet, makes things to process faster, neater and efficiently. Before technology was advanced, nearly everything was slow and required a lot of work and manpower. Typing on typewriter, finding information from a pile of books in the library, doing accounting manually - those are very slow and time consuming process. It is the technology that speeds up everything! Typing things like proposal and study notes using an application, for example, Microsoft Word, made it easier to edit if there is any mistake and able to share with classmates or to others using the internet by upload them to the web. Finding information using internet made it faster. Nowadays, with the help of search engines in the internet, finding information is just a few clicks away. Also, there are free encyclopaedias online which allows anyone to edit the encyclopaedia to keep it up to date. Thus, technology has its advantage to save time and cost for the mankind.
let's see-communication, entertainment, information that about covers it with me\\
Open your eyes and look around you....make a list of all the things in the room that have been made using technology. By the way, technology is using knowledge to create useful productyou didn't have technology you would be living as a caveman did.....duh!\
