NASA developed methods, techniques, and technology which reduces
the errors that are transmitted from spacecraft to satellite
dishes. Without this technology, your satellite TV image would
not be clear. NASA did not invent the satellite dish, they did
find a way to make it work better. NASA developed the
methodology of digitizing images. Each image when sent back from
a space probe to earth is actually a series of many 0s and 1s.
This method of digitizing images was latter used in the
development of the technology for medical imaging, thereby
providing to doctors a highly effective diagnostic tool. The bar
code was developed by NASA as a way of keeping track of millions
of spacecraft parts. This method of keeping track of inventory
is currently used by most retailers across the United States.
The bar code today also has coded into it a specific price for
that item, which results in speeding up the purchasing of items.
NASA developed low cost special plastics which act as a
substrate for printed circuits. Thes
