it's not an investment for me because as far as i'm concerned, it hasn't provided me with a job.
But it HAS provided you with:
1. SATELLITE TELEVISION: Our world would not be the same without the satellites now in orbit around the Earth – all thanks to the space programme. They not only give us satellite broadcast television and radio but also power telecommunications including mobile phones and terrestrial TV networks.
2. SAT NAV: The global positioning system on which our in-car navigation systems are based was developed by the US Department of Defense. They would not exist without the space satellites.
3. GOOGLE EARTH: Mapping was never as accurate as the images we can now get thanks to satellites which from space can even see a dog in your back garden.
4. VIRTUAL REALITY: Nasa-developed research and advanced technology devices allow users to project themselves into a computer-generated environment. When coupled with a stereo-viewing device and appropriate software, it creates a feeling of actually being there.
5. ARTIFICIAL LIMBS: Prosthetic limbs are not new but advancements in space robotics are being adapted to create more lifelike, functioning limbs.
6. DIALYSIS: Modern machines to do the work of the kidneys – for patients waiting for or unable to have transplants – were developed as a result of a Nasa-developed chemical process.
7. MRI AND CAT SCANS: Nasa did not invent magnetic resonance imaging but it has contributed to major advances thanks to research into computer enhancement of pictures sent from the moon. Digital image processing has led to enhanced images of human organs.
8. BREAST CANCER SCREENING: A silicon chip originally developed for Nasa’s Hubble Space Telescope makes the testing process less painful, less scarring and less expensive than traditional biopsy methods.
9. ULTRASOUND TO ASSESS SKIN DAMAGE: An advanced instrument uses ultrasound technology to assess the depth of burn damage immediately, improving patient treatment and saving lives in serious burn cases.
10. EAR THERMOMETER: Removing the need to use intrusive, mercury-based thermometers on newborn babies and critically ill patients, the ear thermometer uses infrared astronomy technology to measure the amount of energy emitted by the eardrum. This is how Nasa measures the temperature of stars and planets.
11. ATTENTION GETTER: Techniques used to measure brain activity in Nasa pilots are being used to improve attention spans for children with Attention Deficit Hyperactivity Disorder.
12. ROAD SAFETY: The cutting of grooves in concrete to increase traction was developed to reduce space shuttle accidents on runways. It is now applied to roads and has cut US traffic accidents by 85 per cent.
13. IMPROVED RADIAL TYRES: Goodyear developed a fibrous material five times stronger than steel for Nasa to use in parachutes to land the Viking explorers on Mars. They expanded the technology to produce a harder-wearing radial car tyre.
14. LANDMINE REMOVAL: Surplus rocket fuel is used for a flare that can burn a hole in the case of a mine and burn away its explosive content.
15. STRUCTURAL ANALYSIS: Nasa software engineers have created thousands of computer programs to find imperfections in aerospace structures and components which has proved invaluable in air safety.
16. WATER FILTERS: Water-cleaning technology has existed since the early Fifties but Nasa came up with ways to filter it in more extreme situations. The activated charcoal with silver ions used in commercial filter systems cleans the water and kills bacteria.
17. FREEZE-DRIED FOOD: Nasa carried out extensive research to reduce the weight of food to be carried on missions. The result was a method for cooking food, freezing it quickly, then slowly heating it in a vacuum chamber to remove the ice crystals. The end product weighs one fifth of the original, while retaining 98 per cent of its nutrition.
18. TEMPER FOAM: Nasa developed a soft, high-energy-absorbent padding to improve crash protection in aircraft. Now “memory foam” is used in mattresses, pillows, military and civilian vehicles, sports safety equipment, amusement park rides, furniture and artificial limbs.
19. SCRATCH-RESISTANT LENSES: A modified version of a process developed by Nasa involves coating the lenses with a film of carbon that helps avoid scratches and decreases friction and reduces water spots.
20. RIBBED SWIMSUITS: The swimsuit worn by Olympic sensation Michael Phelps was developed with Nasa technology. Aerodynamic research came up with material which give 15 per cent faster speeds than any other swimsuit thanks to small, barely visible grooves that reduce friction and drag.
21. AERODYNAMIC GOLF BALLS: Technology is behind the design of golf balls with 500 dimples in a pattern of 60 triangles which allows the ball to maintain its initial speed longer and produce a more stable flight for better accuracy and distance.
22. ATHLETIC SHOES: Moon-boot material has been incorporated into running shoe midsoles to improve shock absorption and provide better stability and motion control.
23. PERSONAL ALARM SYSTEMS: A pen-sized ultrasonic transmitter used by prison guards, teachers, the elderly and disabled to call for help is based on space technology.
24. SPACE PENS: Most pens depend on gravity to make the ink flow to the ballpoint. The space pen was developed for the gravity-free space environment so that the ink cartridge contains pressurised gas to push the ink towards the ballpoint, so you can write upside down.
25. CORDLESS POWER TOOLS: The household and DIY products firm Black & Decker came up with a portable drill capable of extracting core samples from below the lunar surface during the Apollo missions. The same technology has been used on cordless miniature vacuum cleaners.
Virtually all computer improvements from vacuum tubes to integrated chips came from the space program.
and also, as a result of trying hydroponic gardening in low- and no-gravity environments, we're able to develop hardier species of plants that are able to survive (and thrive) in harsher climates-- thus being able to feed those in extremely arid regions.
Space has given us teflon, a material original invented for spaceship vents, but now the best material for kitchen tools.
Ballpoint pens, and memory foam.
The space program has given us velcro, and tons of computer technology.
NASA has weather satelites and helps with crop duster spray system calibrations. In a round about way, this helps farmers to grow with less damage so we can ship the food out. Until 2008, the USA made enough food for ourselves and exported quatities larger than we imported.
The list goes on.
are you giving me any money or food to live off of? it's not like you're going to help me out. when's the last time you helped anybody that needed something calling me selfish? haha... all of this because i disagree with nasa research. i would like to know the hundreds of jobs that nasa has provided in recent times during this economic depression too. as far as i know, i haven't heard squat about nasa providing jobs. i did hear about nasa having to make budget cuts which has led to job layoffs at nasa though. i'm sure there's people in here that feel the same way i do. having the nerve to call me selfish because i'm trying to put a roof over my head with water and food as if someone like you is going to be nice enough to help me out. you can't be serious. those millions of people that you speak of are no different than me as in they're trying to achieve the same thing i am so they're just about as selfish as i am. you're calling all of us selfish. so does that make you selfish too?
