quote [ Launched in March 1958, this grapefruit-sized shiny metal sphere was boosted into a high elliptical orbit. And it’s still there, passing between 650 and 3,800km (406 to 2,375 miles) from the Earth. ]
Remember when a cutting edge research satellite could be installed on the launch vehicle outdoors by a few guys in jackets instead of in a hermetically sealed clean room?
