Spinoffs

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 the national 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 US and other governments' investments in aerospace research. We should be spending more.

Out of a $1.5 trillion US budget, less than 1% is spent on the entire space program. It has been conservatively estimated by US space experts that for every dollar the country spends on the space programme, 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 many people daily. One cannot even begin to place a monetary 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 tumour without the need for a surgical biopsy. This saves patients weeks of recovery time and the cost for this procedure is far less than a full surgical biopsy. With over 500,000 US 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 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 goes a long way to understanding the benefits that space exploration in general, has given us.
