The tool chest astronauts use during servicing missions contains more than 100 tools, including common screwdrivers and wrenches. We would be blind to the heavens. We would not know what made night into day and have no knowledge of moons, planets or stars. We see the tiny disk that makes our days bright. We marvel at the beauty of the stars, the moon and the mysterious worlds that lie beyond.
Telescopes extend that vision to see distant stars and galaxies.
But, we are never satisfied. Our atmosphere allows us glimpses of what lies beyond our capabilities and teases to want more. In 1990, NASA took a leap in this direction. It gave us ultraviolet capabilities and took images of celestial bodies that were the province of imaginations. Technology improves so quickly that electronics are not the same as they were a decade ago.
