They point out that the benefits of space research are not limited to knowledge about space and other planets。 in fact, each of us benefits daily from the many byproducts of these programs. Improvements in radio, television, medical technology, watches, batteries, food processing, and clothing are some of the areas where the space programs have made valuable contributions.Perhaps the greatest benefits have e in the field of satellite technology.
