"When U.S. astronauts stepped onto the moon on July 20, 1969, their voyage was about exploration, discovery and pushing the boundaries of known technology.
In the 40 years since, NASA-related technology has come down to earth. Hundreds of everyday products were developed or modified using aerospace research, from baby formula to swimsuits.
Speaking in April before the National Academy of Sciences, President Barack Obama highlighted scientific advances from the work to put astronauts on the moon:
"The Apollo program itself produced technologies that have improved kidney dialysis and water purification systems; sensors to test for hazardous gases; energy-saving building materials; and fire-resistant fabrics used by firefighters and soldiers. And, more broadly, the enormous investment of that era — in science and technology, in education and research funding — produced a great outpouring of curiosity and creativity, the benefits of which have been incalculable.""
