Electromagnetic radiation and health of exposure. Ultraviolet light, specifically UV-B, has been shown to cause cataracts and there is some evidence that sunglasses worn at an early age can slow its development in later life. Most UV light from the sun is filtered out by the atmosphere and consequently airline pilots often have high rates of cataracts because of the increased levels of UV radiation in the upper atmosphere. It is hypothesized that depletion of the ozone layer and a consequent increase in levels of UV light on the ground may increase future rates of cataracts. Note that the lens filters UV light, so
S-1 (satellite) 4". "S-1" was the first geocentric orbit launch attempt for the rocket; its second attempt on August 14, 1959, carrying the "Beacon 2" inflatable sphere experiment to low Earth orbit, also failed. Eventually, both the Juno II and a re-launch of the "S-1" mission, designated "Explorer 7" or "S-1A", found success on October 13, 1959. The satellite, which ended its mission in August 1961, is still orbiting the Earth today. S-1 (satellite) S-1, also known as Explorer S-1 and Explorer 7X, was a geoscience satellite equipped with a suite of scientific instruments to study the environment around the Earth. The
